E-MOTOR BATTERY MOUNTS FROM TERRACYCLE


TerraCycle makes some great products for our trikes. With the ever increasing popularity of electric motorized trikes having a way to mount the battery is crucial. It is not desirable to mount a heavy battery up high on a trike as it raises the trike’s center of gravity considerably and effects the handling and therefore safety of the trike. Keeping the battery mounted down low and out of the way is important. TerraCycle offers some solutions … some specifically made for certain trike and battery brands and others which aremore less generic. Actually as far as I can tell from their webpage they only have kits for Catrike and ICE (rigid rear) and (suspended models) at this time.

They do offer a highly configurable mount so chances are pretty good they can help a guy (or gal) out with their battery mounting problem. When ordering one needs to specify what trike (brand and model) as well as e-motor system and battery they have so TerraCycle can send the correct spacers needed for the specific kits or to help them in getting you a mounting bracket which will work on your trke.

I said that keeping the battery mounted down low is important as far as the trike’s center of gravity. This is quite true, however, the downside of mounting the battery down low is that it is then very vulnerable to getting water, mud, slush and whatever else flung up on it. I presently have my battery down low, but I am seriously considering mounting it up on the rear luggage rack somehow as my battery is getting so messed up for all kinds of stuff being flung up on it. I don’t like that. When I first got my electric motor pedal assist kit I had the battery located in the rear rack and I didn’t have any issues with handling. The battery certainly stayed a whole lot cleaner up there and it was a lot handier to get to it. Some manufacturers of e-motors offer a special rear luggage rack designed to hold their battery. Unfortunately most of these rack mounted batteries are not very powerful so the cruising range they offer is limited.

A larger battery can be mounted on top of a rear luggage rack, but then the luggage rack can’t be used for a trunk bag. Panniers can still be used. I sure will miss my trunk bag if I end up mounting my battery on top of the rear rack.

The battery can also be mounted on the boom. However, that is a lot of weight sitting on the boom and the boom was never intended to carry weight like this so I don’t know how wise it is to do this. I am not saying that it won’t hold it okay. I just don’t know.

The Beatles said it all in one of their songs … “we can work it out” … and when we do it will most certainly help us to … ENJOY THE RIDE & KEEP ON TRIKIN’

SUNSEEKER FAT TAD ELECTRIC TADPOLE TRIKE


 

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.

THE JOY OF RIDING A PEDAL ASSIST MOTORIZED TRIKE


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.

GIVING UP ON BIONX & GETTING REFUND


Many of you know what all has happened since early last summer when I bought my 350 watt hub motor kit from BionX. At first I loved it even though it topped out at 19 mph instead of the 20 mph they advertise. I did have a problem of the battery not lasting nearly as long as I needed it to, but BionX was good enough to replace the battery with a larger capacity battery free of charge. All was fine for awhile, but then the “pedal assist” mode stopped working and all I had was the hand throttle which was not only a pain to use holding the button on as I rode, but it drained the battery down much quicker than using the pedal assist mode. BionX sent a new replacement motor under warranty, but they sent the wrong motor. This replacement motor lacked the torque (power) the original motor had. It would go 20 mph though which I liked. I complained about the low power, but it pretty much fell on deaf ears thanks to the BionX dealer telling BionX that my unit works properly. I didn’t appreciate that as I know how it worked when I first got it. This dealer didn’t know what he was talking about and wouldn’t listen to me. I talked to both the dealer and BionX about getting a full refund. The dealer said that I would have to pursue that with BionX and BionX said I would have to pursue it with the dealer. After some weeks past I emailed BionX about all of this, but it seemed to fall of deaf ears. I mailed a letter to the CEO/President of BionX explaining everything to him. I asked for his help and told him if BionX continues to ignore me I will have no choice but to contact the Better Business Bureau and file a complaint. BionX never responded back to me so I filed the complaint. BionX had so many days to respond to the BBB about the complaint, but they were silent. Being past the alloted days the BBB contacted BionX again and shortly after I got a phone call from BionX in which I was told BionX wants to resolve this to my satisfaction. I had been saying all along that this replacement motor is not the same motor I had originally, but I was ignored. As far as the dealer was concerned it was the same motor and it worked the way it was suppose to. The phone call from BionX finally got the truth out of them as they admitted that they had sent out the wrong motor … one which was not as powerful. So they sent out what was suppose to be the correct motor and I took my trike back to the dealer for the motors to be exchanged. While at the dealer I took the trike for a test ride and came back very disappointed. It still didn’t have the power of my original motor and the top speed was only 17 mph instead of 20 mph claimed by BionX. A few weeks past by and nothing changed so I emailed BionX requesting a full refund. I received an email reply today saying that the refund is being processed. Once I have the refund in hand and they have their hub motor kit back I will look into getting a different brand as I am sold on having a hub motor with torque sensing pedal assist and manual hand throttle. I will keep you informed of how that goes. Hopefully it will be better than my experience has been with BionX. It is a shame as I really liked the BionX unit. I will miss their display console and handlebar mounted control. They are probably the best of all those in use for e-bikes. I know many people have had no complaints with their BionX systems. I don’t know why I have had all these problems. I sure would have liked for it to work out otherwise. With my expensive but very nice BionX system I was hoping to …

KEEP ON TRIKIN’

update Jan. 16, 2018:  I took the BionX system back to the dealer and got the full refund. Now I am looking to see what I will try next. I am definitely sold on having the electric pedal assist system. I loved having it and am anxious to replace it. BTW, getting a different system can be done for half the cost (or even less) of the BionX unit and it will involve a larger size (power) hub motor and a larger capacity battery.

BIONX UPDATE


Dec. 16, 2017

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.

to BionX

^^^^^^^^^^^^^^^^^^^^^

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.

TERRATRIKE RAMBLER E.V.O.


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”.

From here on everything which appears in this article is someone else’s writings and not mine.

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.

– Electric Assist Hub: The E.V.O. is available in a traditional deraillured system external hub with electric assist
– Direct steering: Horizontal handlebar position provides responsive leverage to steering inputs, and provides a tight turning radius
– Steering stack with bushing/bearing combination for smoother steering
– Chromoly steel frame is lightweight, smooth riding, and capable of supporting up to 300 pounds
– Comfort mesh seat for extra lateral support
– Simple operation, seamless experience
– Powerful 750W direct-drive hub motor
– No pedal resistance when battery isn’t used
– 5 phase motor provides more torque & power
– Up to 1000 recharge cycles per battery
