they do have one class 3 model in the us, the evo city nitro. lots more in their euro lineup, but i guess they don't see a market here for class 3 mtbs.Rebel, Atom, AtomX are names of hardtail BH models. Currently, BH doesn't make any Class 3 e-bikes. It is important to add BH uses different motor brands, for example Brose and Yamaha. They also use so called BH motors, best to be avoided.
I'm curious what would make you put down their hub motor bikes? i have one and have had zero issues, and never heard of any common or repetitive issues with their hub motor bikes.
