I recently finished my electric conversion on a 20" folding bike (no longer folds). I have a front hub motor (BMC 36V 500W high torque geared hub motor). It has the power to climb the hills between work and home. The problem is that it looses traction and the tire slips on even dry pavement.
I have never heard anyone else complain about front hub motors doing this (but most hub motors don't have the torque this motor has). I am looking for some experience-based advice.
- I am running a 90 psi, 20x1.5 tire with just a little tread. I'm wondering if going to a lower pressure tire will help. I'm thinking Big Apple.
- I am thinking about reversing the fork. The current wheelbase is about 40 inches and reversing the fork will reduce it by less than 2 inches and change the weight distribution.
