Hello everybody ,I am a Spanish guy living in Aberdeen ,and after have been reading the forum for a while ,I want to start my project.
The bike is going to be a Dahon Speed 3 ,folding 20" wheels ,with 3 speed hub.After reading the forum ,I am thinking in a Cute Q85 front wheel engine ,250w ,because of the fork size in the Dahon is only 83mm.
I found the engine in 3 different versions ,201rpm ,261rpm and 328rpm.As I am 90kg rider ,and there are many up hills in Aberdeen ,I choose the second one ,261rpm ,trying to find balance.
I am going for a 36v, 10Ah Li Ion bottle battery with integrated controller ,and here is the first of my doubts, which controller do I need? ,there are two options ,a sensorless square wave ,or a Hall sensor sine wave?, the idea is ride the bike with a thumb throttle as much time as I can ,I would like to use it for commuting ,and I don't want to reach the places sweating ,I already have a proper MTB to keep me fit ;-)
There is another option with the controller, 90v-132v, or 200v-264v, I guess that my choice must be the second one.
I am not looking for a big speed ,as I want to keep a low profile ,just go with the same speed than a regular bike ,but without pedalling, and I prefer have a bigger torque.It would be enough for me doing about 15-18 miles with one battery charge.
Any advice would be most welcome ,thanks in advance
