Electric Bike Conversion Kit

There are many different displays sold with the BBS02/BBSHD drive units. Some vendors allow you to choose, others will ship you whatever you get and that’s what you’re stuck with. Any of these displays should work with either the BBS01, BBS02, BBSHD or the Ultra Max. C961 C961 the cheapest and easiest to get of the three displays The C961 is the oldest and has a small display with the three buttons separate from the unit.
