There is a good reason to buy a BBS02! Just needs to be modified for trike bars...

Ultimate bbs upgrade: custom harness to interface bbs motor with standard KT controller, using standard 9 pin connector. Note wiring colours.
Some of them are hidden unfortunately... Can we have a clearer indication shot of the middle domino please?

wow. Great thing. But then you loose programming capability. Is it good otherwise?

well. Big difference in layout. That one you put chain ring outside. On Precialps you have it on inside. As close as possible to motor. Better for chainline and if chain jumps off inwards. And you can mount a chain ring guard plate on the outside position if you want. Ie dual chain ring mounts.

I also have a cheap one on the other bike. Looks similar to your find. But I think Precialps is worth the extra cost.

Well the kt controllers hold one key advantage over standard bbs - they won’t almost immediately fail if one of the connected hall sensors (throttle, brake, speed sensor) go awry.
