Review on 1000W BBSHD BBS03 Mid Drive Motor Kit Electric Bicycle Conversion Kit with Optional 48v 52v Lithium Battery Central Engine and DPC18 Display - DIY Ebike by Bill Wieser

PRO: Powerful engine. I live in a place with steep hills and the engine makes them disappear. If you want to convert an e-bike, this kit is highly recommended. The gifts added work great with the controller and it's easy to set up. CONS: The fit is not as versatile as advertised. My bike's axle radius is slightly larger than the motor axle, so I had to add extra support to keep the motor in place. I didn't like asking for freebies separately, but they came, so I guess it's not that bad.
