Hi , I purchased an Eleglide Citycrosser about 7 months ago and now the bike is unusable. The motor works but the nuts on the hub casing of the motor (the part connected to the sprockets) have all broken inside the motor, also part of the hub casing has broken. I'm unable to get a new motor from www.eleglide.com as they only ship these motors to the EU market. Is there a compatible motor I can get? The motor is 250W 36V with instantaneous power of 400W and max torque of 45Nm. It will be a compatible motor that would work with the existing battery and controller, as well as the torque sensor. Thanks.
