I am not sure what is going on with Bionx since they went into “receivership” Feb. 27th. I know that their website was more less unavailable (non-functioning) following that news. There doesn’t seem to be much of anything available online to read about it. I was just checking out the BionX website and see that it is back up and functioning with no mention of their recent woes. If I hear anything more I will share it here.
update — One reader of this blog reports in a comment that he heard that BionX has been bought out from receivership and is indeed back in business. Sadly, the dealer nearest me has not heard anything out of BionX since all this started.. I have emailed BionX asking them what their current status is, but they haven’t emailed me back yet. It will be interesting to see if the new ownership does anything about the propietary structuring of BionX. I sure hope they make some needed changes.
Some of you know I have had 3 different brands of e-motor conversion kits installed on my trike. I can only speak from my experience with these three motors.
The first was a 350 watt BionX conversion kit. While it worked properly I loved it. Admittedly I didn’t love the price nor the replacement cost for the battery. Also I was not impressed that the largest battery BionX offers is only 11.6aH … only good for about 30 to 35 miles. The motor was a brushless gearless direct drive type which was relatively small yet quite powerful. It had a lot of torque for such a small motor. BionX is a proprietary system which was what I believe caused their downfall. They filed bankruptcy last February 27th. It is all such a shame as they really did have an excellent system. Everything fit and installed normally and easily.
The second hub motor I tried was a Golden Motor Magic Pie Edge. It was large and very heavy (19 pounds). It too was a brushless gearless direct drive type. It had quite a bit of torque, but far more resistance to pedaling with the power off due to the magnets. According to the dealer I bought it from it apparently had a bad controller built into the hub as the voltage from it was too low and the motor would only propel me at 14 mph top speed and that was only for a short time when the battery was fully charged. It ended up down around 12 mph once the battery power started dropping off. The motor was too large in diameter to properly fit in a 20 inch wheel. There was very little room left between the motor and the valve stem so removing the valve core and working with some tools/gauges was impaired and difficult. When I went to install my tire on the rim I found it most challenging and difficult. I had to resort to using tire levers to accomplish it. Once the tire was on the rim it would not easily center up concentric. I had a terrible time trying to get it centered and inflated. I have never had any of these issues with any other rims. When I went to install the wheel in the rear stays I discovered that the axle assembly was too wide and would not go in. (I had previously had 3 different BionX wheels and they all slipped into place quite easily.) I ended up having to spread my rear stays apart in order to get this Golden Motor wheel installed. I read that some of the e-bike wheels are made for a maximum of 7 cogs in the rear cassette. At 7 cogs they are suppose to be 135 mm. If one installs 8, 9 or 10 cogs the width increases and so the wheel won’t fit in a 135 mm space. Again, I didn’t have that problem with the BionX. Lastly, I noticed that the disconnect for the various wiring cables from the axle were far from the rear wheel meaning that when I needed to remove the rear wheel I would have to tear the wiring all apart to get to a place where I could disconnect it. That is ridiculous! It would involve cutting plastic cable ties, removing Velcro wraps, turning my trike over on its side in order to get at this wiring. With BionX and with my 3rd and current motor the disconnects are provided right near the rear wheel. I can’t imagine what it would be like trying to repair a flat tire while out riding. It was a nightmare to work with it in a shop where I had all the tools I might need as well as a means of suspending my trike up in the air off of the floor. Overall I was not impressed with much of anything about this Golden Motor and could not recommend it to anyone.
The third and current hub motor conversion kit I bought and installed is an eZee 350 rpm. As far as I know that is the only identifying information to set it apart from their other motor offering which is a 250 rpm motor. The difference is the 350 rpm is designed for 20 inch wheels while the 250 rpm motors are designed for 26 inch, 700 and similar diameter wheels. The 350 rpm means that it can propel the smaller diameter wheels about the same speed as the 250 rpm motors propel the larger diameter wheels. Unlike the BionX and Golden Motor the eZee motor is geared which means it is suppose to have more torque at low speed but less top speed. That is what I have read. However, my experience is far different. I have found just the opposite to be true. This hub motor lacks the torque the BionX and Golden Motor had, but I have a far higher top speed. The physical size of this eZee hub motor is slightly smaller that the BionX unit. It only weighs about 8.34 pounds so it is much lighter than most hub motors. I am disappointed with its lack of torque for climbing hills. The other motors would “shoot me” up a hill while this eZee motor lacks the ability by itself to climb much of a grade without my pedaling to assist it. Never the less, I am enjoying it immensely and thus far have no regrets about buying it. I would recommend it to others.
I like the fact that I am no longer tied into a proprietary system like BionX. The battery I have now is a 20aH and it costs about 40% or less than what BionX was charging for their 11.6aH battery. With BionX being in bankruptcy I don’t know what the future holds for BionX customers. Right now they have shut down operations and let their 80 employees go. They are looking for an investor/new ownership. I wish them success as I would hate to see all their many customers left with a hub motor system with no support nor parts to keep them operating. I have a couple of friends who have BionX. At this point in time I am just glad I returned my BionX unit and got a full refund. I am not faced with this concern like my friends are. Perhaps someone will start rebuilding BionX batteries and selling them … if that is permitted. If only BionX could survive and get away from this proprietary nonsense which got them into this trouble.
I rather imagine some of the readers of this blog are wondering what all is going on as far as my not posting much on it anymore. I had mentioned previously that I just feel more less drained and in need of getting away from it. That is quite true, but there is another factor which weighs in and all by itself has put the brakes on. My vision has become quite poor and so it is quite difficult for me to do much work at the computer. I had a stroke occur in my only good eye and it has really dealt me a blow. Previously many years ago I had a stroke occur in my left eye which left me legally blind in the left eye. There was no medical treatment for this at that time. A few years later there was so when it happened to my right eye I have been getting treatment since. That being said, things have not been going well and slowly it has worsened. Spending much time at a computer is hard on good eyes, but it is even harder on bad eyes.
As many of you know I also had a Facebook Group called Tadpole Rider Group. I was more less consumed by it spending most of my life involved with it. It was totally out of control and was really taking its toll on me. I had to make the hard choice to close it. Unfortunately something went very wrong and it didn’t totally get deleted. I spent many hours painstakingly going thru all that Facebook required to close it only to have some fluke take place and leave it up to be seen (what there is left of it). I can’t do anything about it as I don’t have access to any of it any more. It is just in limbo … stuck right where it is at appearing just as it does. I have attempted to get Facebook to delete it, but that is a near impossibility … trying to contact Facebook that is. Everything I have tried has been in vain. In short, Facebook is really one screwed up entity.
I still have the desire from time to time to post something more here on this blog, but I find it just too challenging most of the time to even attempt it. I don’t know what the future holds as far as my eyesight. I don’t know if it will get better, stay the same or get worse. There is a posting I want to do right now, but I don’t know if I will be able to. Time will tell. Again, I want to thank all the loyal readers of this blog. I am sorry things have come to this. It has been a drastic life change for me and is something I struggle with to accept and deal with.
At least for now I am still able to ride my trike. Spring arrived yesterday on the calendar anyway. I am hoping the weather shapes up soon and indicates it is aware of it.
Here is a rather poor quality image of my trike with the eZee hub motor conversion kit installed.
I am really enjoying it although I am a bit disappointed with the amount of torque it has. It is a geared type motor which is suppose to be more torquie than direct drive gearless motors. However, it doesn’t seem to have as much torque as the direct drive motors I have had. Never the less I am liking it quite well thus far and have no regrets about buying it as of yet. It is rated at 1000 watts while the BionX motors I had were reated at 350 watts. The first BionX motor I had definitely had more hill climbing ability than this eZee motor has. It would shoot me up a hill just by itself while this motor only assists my pedaling and would do rather poorly on a steep hill or a long incline.
Well, that is my story and I seem to be stuck with it … at least fo rnow.
On February 27th the Canadian hub motor manufacturer BionX filed bankruptcy. In taking this action they did not say anything to their dealers. The overall picture is looking pretty bleak. It is possible that they are attempting to “reorganize” and salvage their business. However, with the problems they have my guess is that this is unlikely. I reckon we will just have to wait and see what happens.
Because BionX chose to design and manufacture their system proprietary and charge way too much for it … especially the replacement batteries … they cooked their own goose. I would think that the only way they could possibly save themselves now would involve changing all this so that they are competitive in the marketplace and attractive to customers. That would be a huge undertaking.
I read that some dealers who are trying to sell BionX items they have in stock at discounted pricing in an attempt to get rid of them before they get stuck with them. It is my understanding that BionX is not selling anything from their website. They probably are not allowed to under the bankruptcy laws. Mind you I know nothing about bankruptcy laws and procedures.
This does not look good for those who have a BionX hub motor system as it is likely that they will not be able to obtain any repair parts or batteries. They will be stuck with a system that is dead in the water leaving them dead alongside of the road or trail. I am so thankful now that I returned my BionX system for a refund. I have a couple of friends who have BionX installed on their trikes. I feel for them if all this comes to pass.
I have more less painted a gloomy picture for BionX and BionX customers … BUT … hey, who knows … they may pull out of this and survive. I am sure lots of folks would be happy if that happens. The truth is I don’t know what all is going on so anything I am saying here is pure speculation and may turn out altogether different than it is appearing at this time.
Below are some links to websites where you can read about this.
And HERE is the official announcement:
“On February 27, 2018, Grant Thornton Limited was appointed as receiver and manager (in such capacities, the “Receiver”) of the assets, undertakings, and property of Bionx Canada Inc.”
For what it is worth I would like to see BionX stick around as they have a nice product. They do need to do away with the proprietary approach to business however and lower some of their pricing … especially on the replacement batteries.
I went for a ride today on one of our local trails. I thoroughly enjoyed my ride thanks to the hub motor. What a difference it makes! Some say (and argue) that you don’t get as much exercise with a motor, but I say nonsense. I am fully convinced I get far more exercise using a motor. It encourages me to pedal faster and work harder to maintain the higher speed I find that there is a night and day difference when I ride using a motor to assist me. That is the key … to assist. It is all too easy to let the motor do all the work and there are those who do this. I try to keep pedaling most of the time while I am out riding. One thing I have noticed is that thanks to now having a geared hub motor with no resistance when there is no power going to it rather than a gearless direct drive like I had previously which has considerable resistance my trike really rolls good maintaining a good amount of the speed I obtained with the aid of the motor (or without it for that matter). And that makes it easier and encourages me to keep pedaling trying to maintain that higher speed … far higher than I go without the aid of the motor. I is just a whole lot more enjoybale riding going so much faster than I can go without the motor. In my opinion it is a “win-win” situation. I am loving it.
Those who have followed my trek concerning electric motor pedal assist on my tadpole trike know about my experiences with BionX. After returning the 3 BionX hub motor and components for a full refund I ordered a Golden Motor Magic Pie Edge hub motor conversion kit. Right off the bat I experienced problems and regretting buying it. The rim was different than any other I have ever had and my Schwalbe Marathon Plus tire was extremely difficult to mount on it. After getting it on the rim it was even more difficult to get it “concentric” on the rim. As difficult as it was to work with in a shop atmosphere I can’t imagine trying to change a flat tire while out riding. Then when I tried to install it on my trike the width was too wide to fit between my dropouts. All 3 of the BionX wheels I had went right into place like any other typical wheel. I didn’t want to, but I ended up spreading my rear stays to gain some width in order to get the wheel into place. Once I got it into place and hooked things up I test rode it and discovered that even though it had very good torque it only had a top speed of 14 mph … and that is only with a fully charged battery. It dropped off down into th 13 and 12 mph range within a couple of miles of riding. It should have been capable of at least 20 mph. It turned out that it had a faulty controller (which like BionX is built into the rear hub). The dealer would have sent me another controller that I would have had to install. That is not something I cared to get into. Then he offered to send me an entire new wheel assembly, but it would have been the same nightmare I ran into with the first one so I said no, I just want to return it for a refund. Unfortuately this dealer won’t refund the shipping charges either direction so I am out a good size chunk of money. I am not happy about it, but there is nothing I can do about it. I returned it and am waiting for a refund.
Another factor that helped me dicide to return it was that there in no place near the rear wheel where the wiring can be disconnected if one needs to remove the rear wheel. I would have to cut a bunch of plastic cable ties and turn my trike over on its side in order to get at all the wiring tucked up underneath the seat to access the nearest plug connection to get it apart. That is ridiculous and I wanted no part of it.
Meanwhile I ordered yet another hub motor conversion kit. This time I ordered an eZee brand (http://www.ebikes.ca/shop/electric-bicycle-kits/ezee/ezee-rear-kit-advanced-pas.html). It is the 350 rpm viersion which is what the 20 inch wheel size requires so that the speed is about the same as a larger diameter wheel has. The 26 inch and larger diameter wheels use 250 rpm motors. According to what I have read about e-bike motors higher rpm is better than lower rpm. Up until now the 4 hub motors (3 BionX and 1 Golden Motor) were all direct drive (gearless), but this eZee is one with gears. It is slightly louder, but not alll that bad. Upon installing it and trying it out in the street in front of my house it accelerated up to 27.5 mph. They only claim a top speed of about 20 mph so I was a happy camper to discover it goes faster.. I took it out for a longer ride and so far I really like it. It doesn’t have the torque that the first BionX motor had nor the Golden Motor so I am a little disappointed in that regard, but overall I like it quite well. I expected the torque to be equal to or greater than the direct drive motors since it has a 1:5 gear reduction and the motor is rated at 1000 watts at 48 volts. I discovered that the top speed I obtained of 27.5 mph dwindles down as the voltage of the battery goes down. Only when I had voltage in the low 50s could I obtain the higher speed. As the voltage dropped down into the high 40s my speed fell off to about 25 mph where it stayed for quite some time. By the time my battery voltage fell off down into the mid 40s my top speed reduced down to about 23 mph. I am plenty satisfied with that.
Between this hub motor kit and the battery, battery charge and rear rack the battery mounts in the cost was less than $1800 and I am not locked into a proprietary system like BionX where they charge 2.5 to 3 times as much for a replacement battery as I can buy one for now. And I can get a far more powerful battery for less money. BionX doesn’t even offer such a battery.
As to the physical size of this eZee hub motor it is about the same as the 350 watt BionX hub motor. One thing I don’t care for with this eZee hub motor is that the wiring comes out of the end of the axle rather than out of the side plate of the hub motor like BionX and Golden Motor did. I think that is just plain stupid, but a lot of hub motors are made this way. In fact, most of them are.
Yes, I could have bought a cheaper hub motor kit, but I don’t think I would have been satisfied with it. I did a lot of research and reading about various hub motors before making my decisions. unfortunately my choice of the Golden Motor turned out to be a bad choice and it was an expensive lesson. Now only time will tell if my last choice was a really good one. Right now I am a happy camper. I don’t yet have the torque sensor installed and working so I am only using the hand throttle. I am waiting on a new crankset to arrive as the torque sensor is the wrong sloine size for my existing crankarms. Having to replace my perrfectly good crankset is an additional expense I was not counting on, but if I want the torque sensor to work I have no choice. And I do want the torque sensorr installed and working so it will be a true “pedal assist” unit.
HUB MOTOR VS MID DRIVE MOTOR … yes, the argument goes on. Some say Mid Drive is the only way to go while others say Hub Motors are the only way to go. Hey, they both go and like with most everything there is good and bad & pros and cons concerning each. HERE is a well written and informative article about the subject. I think I made the right decision. I like hub motors. Mid Drive just doesn’t appeal to me. They are hard on the drive train and if the drive trail fails while you are out riding you are done for as the motor can’t help you. With a hub motor you can still go on down the road/trail since it doesn’t rely on the drive train. My thinking and position lines up with the conclusion of this article and this company has worked with them both and speak from experience and hands on knowledge.
Although this following video (and nearly all others I have seen on this subject) is about bicycles it does a good job of covering the topic.
This is an interesting trike. I have a hard time understanding some of this man’s English, but the trike is pretty neat. If nothing else, seeing how he has mounted the skis on the front wheels might give others an idea of how put skis on their trikes, myself included. I have thought about it.
Anyone who has been following this blog knows I had a BionX hub motor system installed on my trike and that I experienced various problems with it that BionX never got resolved to my satisfaction. Consequently I requested a full refund and got it. Dispite the problems I experienced I really liked having the hub motor system on my trike and I really miss it now that I am without it. It has always been my intention to replace it with some other brand. I have spent a whole lot of hours researching to learn what is available in order to make a decision I am hopeful is the right one for me. I have listened to the counsel of others and considered the options.
I ruled out mid-drive systems as they just don’t appeal to me. If for no other reason I don’t like the idea of putting all the strain and wear and tear on my drive train. Also most mid-drive motors I have heard while watching videos of them were loud and I found that objectionable. I don’t like the idea of having a motor hanging on the end of my boom and I am not willing to give up two of my chain rings up front in order to have a motor placed there. I have 27 speeds and I want to keep them.
I like hub motors even though I know it makes dealing with a flat tire more complicated and difficult. But I usually run Schwalbe Marathon Plus tires and don’t get flats so that isn’t much of a concern. There are two basic types of hub motors … brushless gearless and brushless geared. As with most things there are pros and cons to both. After much studying I made the decision I wanted to stick with the brushless gearless type which is what BionX is. Hub motors with gears inside of them require replacing the gears periodically as they wear out. I didn’t want to get into that. Also brushless geared hub motors are usually noticeably louder that the brushless gearless type. I like my motor to be quiet. I mean … I may want to sneak up on somebody. 🙂 Seriously, I just like keeping a low profile. I would rather not draw attention to myself and my trike by having it produce noise others hear. Besides it is both annoying and embarrassing.
In my research I found that it is extremely easy to find hub motor kits for 26 inch wheels (and larger). However, finding them for 20 inch wheels is somewhat challenging. The lead mechanic at a local bike shop was also looking for a hub motor system for me and said the same thing. He found it difficult finding a hub motor kit for a 20 inch wheel. But with a lot of time and perseverence I did find a few. Within these “few” I had to select one and that can be difficult. I read all I could about the different ones. Only a few of the few had much of anything written about them so that narrowed it down some as I didn’t want to go into this blindly.
There are various sizes of motors available. My BionX was 350 watts. I have seen 250, 350, 400, 500, 600, 750, 1000, 1500, 2000, 3000, 5000, 10000, 15000 and even higher. I am sure riding a trike with a large motor would be exhilirating. However, I am pretty sure I would end up wrapped around some tree or worse. Besides the larger the motor the more battery power it requires and uses. The bottom line is one only needs enough power to do the job. My 350 watt BionX motor was pretty decent power-wise so 500 watts should be about perfect and sensible. BTW, here in the U.S. the legal limit for road use is 750 watts. In Canada is it 500 watts and in Europe it is only 250 watts. (I sure am glad I don’t live in Europe.) 250 watts is ridiculous. That won’t even climb many hills.
Most of the hub motors have the wires coming out of the end of the axle. That absolutely turns me off so I didn’t consider any of them. I don’t like the idea of their vunerabilty of getting damaged. So with this criteria the candidates were narrowed down considerably.
I am not going to name brands here for fear of offending someone who happens to have one of those brands. I may or may not have something against any of them. I am not here to put any other brands down or to advise others what I think they should buy. I am only concerned about what I think will be the best choice for me.
After a lot of deliberation i chose the Golden Motor Canada Magic Pie Edge hub motor. It is not the cheapest by far, but it is still reasonably priced. I bought my battery, charger and rear rack for the battery seperately as Golden Motors didn’t have what I was looking for. The total cost for the hub motor kit with the extra options I selected was $781.50. The battery, charger and rear rack was $560.49. Altogether it comes to about $1350. The BionX system I just had was nearly $2500 so you can see there is quite a difference is cost. As I said earlier the BionX was a 350 watt motor. This new one is 500 watts. The BionX battery was only 11.6 aH (the largest they offer). This new one is 20aH. I have seen as high as 50aH. I based my decision on this 20aH battery on what I experienced with the 350 watt motor and the 11.6aH battery. The range I got out of that combination was not very impressive … only about 35 miles on a good day. In colder weather it drops way off. The replacement cost of the BionX battery is over a thousand dollars. I can replace this battery for less than $400 (at least that is what I see currently looking at batteries). I would probably opt to spend more however and get a lithium-polymer battery next time instead of lithium-ion. They are still far less money than the BionX battery costs and are a much more powerful and higher quality battery than the BionX battery. I wanted to get a lithium-polymer battery at this time, but I also wanted to hold the cost down so I opted for the lithium-ion.
One thing I want to address here is the matter of the pedal assist mode and torque sensing being built into the circuitry inside of the hub motor. BionX does this. It is great until something happens to it like what happened to mine. My pedal assist feature stopped working. Fortunately it was under warranty so BionX replaced the hub motor. Unfortunately the motor they sent to replace it was the wrong motor … much less power than the one I had that went bad. This new motor I ordered does not have pedal assist or torque sensing built into the circuitry inside of the hub motor. It is a seperate external component which costs about $145 or so extra as it is optional. At first I was upset about this, but after thinking it over I changed my tune. If something were to happen to the torque sensing unit and it quit working it is a far easeir repair (for me) than BionX repair would be. Warranties don’t last all that long and then we are on our own. Repairs are out of pocket at that point. I don’t know what BionX charges for a new printed circuit board, but I would much rather replace the external torque sensor than have to open up the hub motor and replace the printed circuit board inside.
Lastly, this new motor has a few features BionX doesn’t have. It offers a reverse feature so one can use the motor to back up. It can be programmed offering three different selections of the rider’s choice as to how much power the motor is delivering. Typically one programs it to have a low power choice, a medium power choice and a high power choice. These can be selected as one is riding. By law here in the U.S. an e-bike (e-trike) can’t go any faster than 20 mph on roads when being powered by the motor. It seems so silly when there are riders who can obtain 40 mph or so thru pedaling. Many motors are capable of propelling the bike/trike faster than 20 mph, but by law they must be limited to a top speed of 20 mph. With this motor being programmable one could choose full power as one of the 3 available selections. That would propel the cycle much faster than the 20 mph top speed allowed. I tell you what … I won’t tell if you won’t. 😉 I am sure there are many who would choose to have full power available as one of the selections. It not only would provide the highest top speed obtainable, but it would provide maximum acceleration and performance. Anyone up for a drag race? Am I getting too old for that?
Well, that’s my story thus far. It is all on order. And yes, I am very anxious to get it and get it installed and working. And then I hope to …
KEEP ON TRIKIN’
I will keep readers updated. BTW, as stated, this is round two and hopefully it will be the final round.
If you can handle the weather this looks like it would be fun …
Utah Trikes is known for their customization services. Here is one of their projects. With 1600 watts there is plenty of power. Along with all that power is plenty of noise … something I find quite objectionable. I guess it doesn’t bother some people.
What will they think of next? We talk about the extreme comfort of a recumbent tadpole trike comparing it to a recliner chair and then somebody comes along and undoes all that has been accomplished in creating such a dream machine. I am talking about standing up while riding a tadpole trike. Yes, you heard (read) me right! Hard to believe, huh? The picture up above is just a drawing, but this thing really exists. Actually the inventor/builder has had several prototype models thus far … with the goal of improving it with each new design build. Obviously the appeal of this machine would probably be only those who are into skate boarding, snow boarding and surf boarding. That leaves me and a whole lot of other people out. I guess I am thankful I was born when (and where) I was as there are just many things younger people do that I am so glad were not around when (where) I grew up.
See? I told you so. It doesn’t appear to be human powered, only electric hub motor powered so there is no exercise involved in riding it. And that is one big hub motor so I assume it is fairly powerful. I found this video which explains several things about this machine.
It is a tadpole trike, but it certainly isn’t recumbent. It is just the opposite of recumbent as the word recumbent means “prone position” or “lying down” … no , it doesn’t mean “feet forward out in front”. There are a whole lot of tadpole trikes being sold labled as recumbent and they really are not recumbent at all. I read that there is a seat kit available for this trike so I reckon it may be able to transform (morph) into a recumbent trike of some sort. 🙂
I look at this and it just screams UNSAFE. But then that is what I think of skate boarding too … insane! It is like tempting fate. I can’t imagine trying to make a panic stop on/with this trike.
Riders of conventional tadpole trikes can ride on a 100 mile ride all day long in great comfort. One sure couldn’t do that on one of these. Oh well, different strokes for different folks. I don’t understand it, but that is okay I guess.
Here is a newer prototype …
Here the inventor/builder takes the trike for a ride around his city …
I wonder how many of these he will sell. Hey, in this crazy world we might be surprised. Hey, if they can ENJOY THE RIDE more power to them. Too bad they aren’t getting any exercise in the process.
For those on a tight budget here is an option available for a fairly reasonable price. One can also get the same trike without the FAT tires and wheels for a lesser amount. And, of course, one can also get the same trike without the electric motor system.
And Utah Trikes offers the same trike with a Bafang motor mounted on the end of the boom. This particular one is customized for the customer. It has dual cargo racks on the sides and dual batteries mounted undernearth the cargo racks.
I came across this video and thought it would be a good one to share with others. This man rides a HP Velotechnik Scorpion FS26 Pedelec trike which is a factory made electric motorized trike rather than an after market add on kit.

NOTE: Today I sent an email to BionX requesting a full refund. The new hub motor they sent still has the issue of not being able to obtain the advertised top speed of 20 mph. It also does not have as much torque as the first motor I originally had. As much as I like their designed system I am tired of all the problems and not getting anywhere getting them to resolve them. I will buy a different hub motor system later on after I get the refund.
Nov. 21, 2017
NOTE: I just got off the phone a few mintures ago. A man from BionX called me to discuss my issues. They admitted that they had sent me the wrong motor as replacement under warranty and this is why I have been having this issue with the hand throttle. They will be sending out the correct motor which has considerably more torque. This has made my day. Below is what I had written for this posting which will be published Nov. 24th. I am leaving it here so readers will know what has transpired prior to this phone call I just received. Needless to say, if they get my problems/complaints all resolved I will gladly change the thumbs down to a thumbs up as I really do love the BionX system on my trike.
As many of you know I have been having problems with my BionX hub motor kit I purchased last summer. Although BionX has taken care of some of the problems I am still dealing with the hand throttle problem and BionX is not doing anything further to help me on this despite my pleading, attempting to reason with them and even threatening them. I eventually filed a complaint against them with the Better Business Bureau hoping they would be concerned about having that on record against them, but it hasn’t made any difference. They didn’t even bother to respond to the complaint. I don’t know what is going on, but I have pretty much written them off as a company that business dealings should be avoided. I had told BionX I would be filing a complaint if they continued to ignore me and refuse to resolve this issue. I truly don’t understand why any legitimate business would not want to address this complaint and satisfy their customer rather than receive a bunch of bad publicity. They don’t seem to take this seriously nor take me seriously, but I am most serious. I paid a lot of money for this hub motor kit and I want and expect it to work right like it did when I first bought it. I don’t think that this is asking or expecting too much. It is looking more and more like I have ran out of options and won’t get this made right by BionX. They don’t seem to care. And so as a result of all I have been dealing with and continue to deal with I can not recommend BionX to anyone. They get a big thumbs down from me.
Remember – they finally contacted me and say they will take care of me and get this resolved to my satisfaction. If they do as they say I will be most happy to give them a thumbs up.
By the way, just as a side note … I have noticed that battery performance is only about 50 % in cold weather of what it is in warm weather. My friend who has an identical setup as mine says the same thing.
Matt Shumaker used a KMX Typhoon tadpole trike modifiying it considerably, especially the frame, to create this powerful monster. There is no doubt about it … he achieved his goal in making a strong frame.
He lowered the frame 3/4 of an inch and also widened the frame 5 inches and lengthened it 3 inches to accommadate the motor and increase the handling of the trike. With two 15 hp (11,000 watt) motors powering it these modifications are a very good idea. Matt says it will accelerate from zero to forty in 4.5 seconds! That would indeed be exhilarating.
It sounds like a jet airplane going by. He says he has about $6,000 invested in it plus about 200 hours of time. He values it at about $9000. It is all wheel drive with motors for the front wheels and motors for the rear wheel. The trike does have pedals in case they are needed. The trike weighs about 90 pounds so pedaling it isn’t something one would want to do if they didn’t have to.
Matt reports that the range is about 35 – 45* miles on a charge which is a whole lot more than my 80 mile rated BionX battery gets. I am only getting about 20 miles using 80 % of a full charge on my BionX unit … not very impressive. Of course, this is a massive battery in comparison to what I have. (* one place I read 35 if it is babied and another place I read 45 with no remark about babying it.)
With all that power and speed it requires some hefty brakes. He used 203mm Hope 4 piston hydraulic brakes.
Matt reports that he sold this trike for $7500 with only one motor as he removed one.
A few tadpole trike manufacturers are offering electric motorized models. One of them is TerraTrike. I applaud this as having a BionX unit installed on my Catrike I really love having it. I have a friend I ride with who has a BionX unit installed on his TerraTrike Rambler. The BionX unit is a great unit as long as everything works right (mine doesn’t), but it is expensive. This E.V.O. model is far less money although feature-wise I much prefer the BionX unit. That being said, this Falco unit is 750 watt vs. the BionX 350 watt and it offers a 2 mph reverse as well as a crawl forward from a standstill. BionX has neither. Of course, the thing about this deal which is a real turn off for me is the fact that it is a TerraTrike trike. I just am not impressed with them as I think they are poorly designed and built. I would much rather spend $500 more and get a high quality well designed trike such as Catrike. So many TT owners admit that they regret not buying a better quality trike. For me personally there is absolutely nothing about the Rambler that appeals to me. It would have been a good candidate for a book entitled “unsafe at any speed”.

TerraTrike’s Electric Vehicle Option (or “E.V.O.” for short) will transform the way you ride and will increase your range by degrees of magnitude. It will allow you to climb hills that were previously daunting, it will keep you spinning through rolling terrain. The Rambler E.V.O. is not intended to be an electric trike. The E.V.O. was designed to help you along your journey while you still get the cardio benefits of trike riding. You will hear and feel the motor turning on and off as it senses your need for assistance. You will still be shifting the trike as you normally would; as the hills get steeper or as you come to a stop.
With a generous range of up to 60 miles per charge, you will have nearly limitless potential. The lithium ion battery can be charged overnight with the included “smart” charger. Simply plug the charger into a nearby outlet, or the battery can be easily removed from its case for charging in a different location.
TerraTrike figured out the ideal torque sensor setting and assist level so that it is very predictable and optimized for assistance and range. The top speed is governed at 20 mph. The Rambler E.V.O. motor control accessories available are ‘Wired Plus Minus (WPM)’ ‘Wired Console’ and ‘Wireless Console with Plus Minus’. The trike will still be limited to 20 mph, but you will be able to adjust the level of assist (low, medium, or high) or you can put it into one of three regenerative modes which actually charges the battery on long descents.
The optional Wired Plus Minus (WPM) switch also adds a reverse gear. You will need to back pedal while it is backing up due to the drivetrain of the trike. But don’t worry, max speed in reverse is 2 mph. The WPM accessory can also help climb hills by providing a “crawl” feature. It too is limited to 2 mph and is merely intended to get the trike rolling so that you can begin your pedal stroke. After the trike starts to move and you start to pedal you can let go of the plus button and the motor assist will kick in as appropriate.
