I have a decent mountain bike and I was looking to transform it into an ebike. I’ve seen that there are mainly three main options to do this:
– a rear wheel hub
– a front wheel hub
– a crank motor
Considering that I don’t have much experience (close to zero) in modifying bicycles, I would really love to learn from someone having more expertise .

Does it make a big difference the position of that electric motor (front, rear or middle) when it comes to a “heavy load” like myself?

Found this type of motor, but I’ll have to drop my 3 existing gears… I don’t know…

Thanks in advance for anyone happy to help me here.
