Have seen a post on here saying the gtech motor is a bafang hub. Would it possible to buy a front bafang motor and connect to the original battery/controller. Change rear to an igh and keep the belt.
You could fit any hub as long as the connector is correct and drops outs are standard 9mm QR, other issue is extending motor cable. Extensions are available.
There's absolutely no point in doing that. It would make much more sense to start with a normal bike, so you can use a standard battery and controller, which will be much cheaper and easier to service.
Thanks, just looking at ideas to see if i can add gears to the gtech for under £300, looks like a front hub using original battery will be the easy and cheapest way to go. Or sell it and buy the orbea gain.
