Has anyone else with heated hand grips found this? Am I destined to live a life of cold, winter motor-biking hands? I've been having electrical issues with the Trumpy. The mechanic has checked it all, ruled out the obvious causes and has come to the conclusion that it's the hand grips draining the battery. It sounds logical because I had exactly the same problem with my previous bike (and same brand hand grips). Has anyone else found this? Any solutions? I LOVE my hand grips. Is it possible to have both a bike that goes and warm hands?
