I have an electric bicycle that is powered with a front wheel motor. I have been using the bike regularly for 3 years with no major issues. Recently, the front forks of the bicycle (it's a giant mountain bike) sheared off (where the wheel connects to the forks). I had wondered if this might happen. A bicycle is designed to be powered via pedals not via the front wheel. The forks were replaced but the same thing happened a week later. Has anyone had any similar experiences or can recommend a 'strengthened' set of forks that may prevent this from happening again.
