hello boys ... I'm in the process of making my electric motorcycle ... but I do not know which motor to put ... HUB engine or central engine ... the motorcycle weighs approximately 20kg design format choper cruise rwheel fat bike de 26 ". ... I was thinking about an engine 3kw ... is a motorbike ride, but I want power and speed when required, do not go more than 90km / hs and have torque to climb slopes without problems ... I read that the hub engines do not have much torque and come just for e-bike or am I wrong? Which of the two engines is better? Thank you
