Hey everybody, i'm pretty stoked about converting my bike to a motorized bike, but I have a few questions before committing to one brand/building one. Question #1: I have a 24 speed mountain bike(GT Avalanche 3.0), is there a particular brand of motor kit that will work best for my bike? Question #2: I have been to pistonbikes and bikeengines and a few other websites. There is a huge price difference in these sites, pistonbikes starting around $150 and bikeengines being on average around $500. Would a $150 be sufficient for a first-timer? Thanks for your help!
