As much as I enjoy my trikes equipped with the NuVinci auto shifts (Developer Kits), they aren't very efficient or very easy to pedal without using assist. Over a year ago I installed a Bafang BBS02 on a bike for one of my sisters. She was having some problems with the BBS02 so I got her a new BBS02 from Paul at EM3EV. Then with Paul's help, I repaired the older unit, which I have now installed on a Performer Trike-X. My first thought was to replace the mid-drive on one of my existing trikes with the BBS02, but rationalized my way to doing a whole new project instead.
One of my requirements was to end up with a rear derailleur and the 9 speed on the Performer should work fine.
The only modification I made to the original trike (other than installing the Bafang), was a longer rear seat support, 5" long instead of 2 1/2" long. I did this for my riding position, but it also left enough room for a 48V 10AH Ping battery between the seat and the rear rack
I've just completed the electrical work and haven't ridden the trike outside since installing the Bafang, so more to come later.
Edit: Battery was moved to rear rack bag and switches and Watt meter are between the rack and the seat.
Edit: the links below are for the old mid drive builds that used the NuVincis and 9C motors
