Has anyone had issues with broken spokes on their Lextric XP? I had 5 spokes break last October all in the same area of the rear wheel. I replaced the spokes and trued up the wheel. Now I have 6 broken spokes in various positions on the rear wheel and the outer rim is out of round requiring replacement. Lectric has indicated that it would be best to replace the whole wheel but will not cover it under warranty and is offering a discounted replacement. I am wondering if the spoke design has a flaw and if anyone else is having this issue.
