i followed the directions on putting the bikeberry motor together and it doesn't work after 8 weeks of the purchase. someone said i shouldn't follow the bikeberry instructions and throw them in the trash and they said i need to put the bike away and read hours and hours of instructions on how to make the bike work instead of calling customer service for help. i stated that i regret the purchase and would never purchas again from that company. they told me that it was my error, operator error and not the motor kit. sounds like a lot of BS.
