Just taken delivery of a Haibike sDuro Cross 6.0. Decided to take in-tube battery off bike to charge. According to handbook the Yamaha battery cover should slide off, no chance...So loosened top and bottom screws, still no joy, so unscrewed completely. Operated lock, battery fell forward but.....could not then remove it. Bugger it decided to charge in bike, clicked battery back and replaced lower screw, slid in cover but upper screw now about 1/4 inch above hole in frame! Did eventually manage to lever in but suspect x-threaded as top of cover now about 1/2 inch proud of frame. Am I completely thick or is this a widely-experienced problem. Any easy manipulations to solve this would be appreciated!
