Although this posting is about the Tongsheng TSDZ2, mini 750W crankdrive(or as some call them middrive) e-motor it started out talking about what trike I would buy if I were to get a new trike today and led into what e-motor I would choose today. So it is mostly about this particular e-motor.
I have had my Catrike Trail since 2009 although my current trike is a 2013 frame (original frame was replaced by Catrike under warranty when I discovered a hairline crack alongside of a weld on the underside of the cruciform) and nearly all of the components have been changed at least once and upgraded from what it originally came with. I have a lot of money invested in my trike so it would not be cheap to replace it today. I really love my Trail but truthfully if I were buying a new trike today I think I would get the Eola and customize it some. The newer Trail model does not appeal to me. I have no use of a folding model nor the adjustable seat back. I much preferred my 2009 model which was the “space frame”.
The Eola has the space frame and really appeals to me. Since I have an e-motor the fact that the Eola is only 11 speed is not a concern to me as I would be motorizing it.
I have always had a hub motor and prefer a hub motor over a crank drive motor. However, if I were to buy a new trike and motorize it I am seriously considering going with a crank drive … something I did not think I would ever do. And I think I would go with a Tongsheng TSDZ2, mini 750W crankdrive motor. I am certainly not saying it is the very best e-motor in the offering but it is one that has caught my attention.
As you can see it is fairly small in size. It has built in controller with torque sensing. I have read and heard nothing but good reports about this motor. There is one exception, however, and it concerns me greatly. It is said that one must be careful not to overheat this motor as it will get damaged all too easily. It is recommended not to try to use too large (voltage wise) of a battery because of this. 48 volts is the most recommended. Even then the rider dare not ‘hot dog’ with it.
Two chainrings can be used on this motor.
Here is the display unit that comes with it.
Yeppur, it is a very nice looking unit and is fairly low cost … about $400 not including the battery.
