E-motor conversion for tadpole trike

[Bill Jackson]

I have just ordered a Bafang BBS02 750 watt mid drive conversation kit for my HP VELOTECKNIK Scorpion FS 26 recumbent folding trike. The trike has a 3 speed internal hub transmission in the 26" rear wheel. I plan to wait until this rear 3 speed hub fails before I replace it. However, I am having problems finding a suitable replacement. The 11 speed NuVinci planetary transmission is attractive but the literature says the 380 model only supports 350 watts.. Shimano also has a rear hub transmission but I am having trouble getting information on there rear hub transmission models.
Can anyone give information on how I might proceed?

There is good article here by one of our own "spinningmagnets".

I just built a wheel with a S-A 3 spd that is also a freehub. It is great so far but I will need more time with it before I can give a good evaluation of it.

The N380 is rated low. I , as well as many other forum members have used them behind BBSHD's with no problem. They will handle that BBS02 just fine.

The Nexus 8-speed IGH has a 307% shifting range from its lowest gear to its top gear. the NuVinci 380 has a 380% range, and is quite possibly the best IGH for the BBS02 ever made. It can also be converted over to using a belt instead of a chain, but I don't know what issues have to be ironed out to accomplish that.
