NOTE: Since I wrote this article I bought the Tongsheng crankdrive motor and installed it on my trike. It lasted less than 2 months so I was not impressed with it and therefore I can not recommend it. The motor quit working and while it was working it destroyed my drive train costing a small fortune to repair. The mechanics at my local bike shop agree with me that crankdrive motors are rough on the drive train. I would recommend the 1000 watt Bafang that offers torque sensing.
I have a hub motor on my trike and quite frankly I am not a fan of crank drive systems for various reasons. However, certainly crank drive systems are quite popular. Probably the name we hear the most is Bafang. I am sure it is a good system and lower cost than most others making it an attractive option. One can spend more money … much more … and do better. Recently I visited the website of Victory Cycles in Kokomo, Indiana. I have dealt with them several times. I bought my first e-motor from them, a 350 watt BionX unit. As many know BionX went out of business leaving their dealers caught off guard. Victory Cycle sold lots of BionX units so when BionX went belly up they found themselves in a predicament. They had lots of customers who want an e-motor on their trike. Having lost BionX they had to come up with something. They started looking at what all is available. Since BionX is a hub motor system they hoped to remain with a hub motor. They tried one well known brand (which I won’t mention by name) but ran into lots of issues so they said goodbye to that company and continued their search. They looked at Bafang but decided against it. You can read about this HERE. The bottom line is they objected to Bafang saying that it is not smooth. So their search continued and led to the two systems they are selling today. Both are crank drive. You can read about these two systems by clicking on the same link above.
One is the TONGSHENG TSDZ2 750 Watt mid drive system which they sell for $1800 installed on most tadpole trikes.
The other e-motor they sell and highly recommend for Catrike is the Bosch E-Cat system which they sell installed for $2600 on a new Catrike you buy from them or you can have them install it on an existing Catrike for $2750.
I am sure that the Bosch E-Cat system is a very good system, but I personally don’t think I would want it for two main reasons. First it is only 250 watts … which just isn’t enough in my opinion. Secondly, it is e-assist only. No hand throttle is available. That is a real turnoff for me. That being said, I am sure many will love it and not have an issue.
The Bosch Active Line Plus electric-assist system features four power assist levels: Eco – 40%, Tour – 100%, Sport – 180% and Turbo – 270%. Each level also features a maximum drive torque to ensure smooth, gentle acceleration. The Bosch Active Line Plus delivers assist up to 20 mph and a cadence of 105.
That is the straight skinny from this dealer. This is what they recommend and sell to their customers. I ponder over the question of “would I consider going with a crank drive system” if i were wanting to buy a new e-motor for my trike. Right now if I had to answer that I think I would say no, I will stick to a hub motor system. But again, that’s me. Many like the crank drive system. If you are interested in why I prefer hub drive you can read about it HERE.
Having an e-motor on a trike most definitely helps us to …
