New to e-bikes, I'm looking to equip my carbon frame road bike with a 36volts, 250W, front hub motor to assist with hill climbing, in some cases fairly steep. No assistance needed on the flat, when there should be minimum resistance from the motor!
Would appreciate advice on what motor parameters to consider, particularly gear ratio (am assuming direct drive wouldn't provide sufficient power).
Will be building a new wheel with the motor, using a 36 spoke, 700C x 23mm rim.
As an electronics developer I'm also planning to design my own controller, preferably using or based on an already proven, bullet proof design that fully protects the motor from over heating (the motor will of course need temperature sensing, probably retrofitted).
