Just for everyone's information and enjoyment I just finished converting may older Bacchetta Giro 20 recumbent to an Ebike version. Purchased the Bafang BBS02B kit a couple months ago. For the most part installation went pretty smoothly. I had to lengthen the battery power cable that came with the kit. Extender cables are available but cutting the cable and extending it was very easy. I ended up having to make a anti-rotation stop near the bottom bracket so that the motor would not rotate upwards due to the tremendous torque produced. You just can't tighten the nut on the bottom bracket enough to keep the motor from rotating. On a conventional bike this rotation is inhibited by the up tube between the bottom bracket and the head tube. The piece of 1.5 x 0.5 inch aluminum made a good mounting point for the headlight. The kit came with a very nice pannier rack with a battery compartment built in. So far so good. Getting about 40 miles/charge from the 750Wh battery.

I like the conversion, especially the torque bar and the way you attached the headlight.

Thanks. I had seen on this forum some photos of people making a bracket that mounts to the bolts on the motor and then clamped to the main tube. The bar was a bit less effort and seems to work well. I should also mention that I had to lengthen the speed sensor cable because I decided to mount it on the rear wheel instead of the front.
