I've had my converted Magnum Metro on the road almost a year, and the motor has always been nearly silent. Lately though, it's making a sound a lot like a geared hubmotor - not sick sounding, just an obvious machine-like whirring sound. I had the bike worked on by a VeloFix bike mechanic recently, and he told me that when he put the rear wheel back on after tuning the spokes, that he had to 'rearrange the rear axle washers'. I'm not sure if that could be it, or not. I loosened the axle nuts a quarter turn, thinking he might have put too much pressure on the bearings, but I don't think it mattered much if any. Any insights would be welcome.
