Last week I purchased an Izip E3 Path+ bike from my local electric bike shop. After two days of riding (~35 miles) I heard a grinding/rattling sound coming from the rear hub where the motor is located. The bike would move at normal speed, but when lifted off of the ground, the rear wheel would not freely spin. It would come to a stop immediately. I took it back to my bike shop and they confirmed there was something wrong with the motor and swapped my wheel and motor with another Path+ model in the shop. Three days later and now at ~90 miles, the same exact thing has happened again. I will be taking the bike back to the shop tomorrow. However this time they will not have another replacement wheel for me and I'm certain to be waiting days for a replacement to arrive. Needless to say, this has shaken my confidence in the Currie Tech motors and the Path+ bike. I'm uncertain as to what I should do. Do I roll the dice and get another replacement motor, hoping that it was only pure dumb luck that I got a couple of motors from a bad quality control day at the factory, or do I just tell the bike shop owner I'd like a different brand of bike. Anyone else with these issues?
