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.

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.
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.
