I have fitted a new front rack and added weight. Fitted a new front 'deep tread' knobbly tyre. Let air out of the tyre down to 10psi. I only use power level-1 and yet i still cannot get good traction on hills in dry conditions. Riding in damp conditions is a no go. Fitting the motor into the back wheel is the only answer i think? How can i achieve this at a reasonable cost?
