Hi: I am a new forum member and the proud owner of two almost brand new EV Global bikes. Unfortunately, they are in my home in Tucson AZ and I would love to outfit my Gary Fisher Mountain bike with a front hub, Li battery-powered kit. Anyone have a suggestion? It would be neat to have 21 gears sitting in the back wheel and a power assist on the front.........like a Quattro is to a regular Audi. Let me know what you think. Thanks.
