Starting new build, your thoughts?

FWIW I've never even ran the bikeberry gearbox, its brand new & looks decent built. But I've heard of failures of them, but they were big dudes at 240-280lb on a motorized bike.

Your big problem is mounting the motor/gearbox to the bike frame. There was a
solution, a special mount for chain saw type motors but it is no longer available.
If you find a solution, let us know.
