Hello to all, I'm Nicholas from Tempe, AZ. I have a Novara Ponderosa 29er mnt bike that I have been interested in doing a motor conversion on for awhile now. Originally was thinking of building up an old full suspension, however I think this big wheeled hard tail will make things a little easier. My plans are for a quiet 4 stroke with plenty of low end grunt. The bike will be primarily used for exploring difficult trails in the local desert and mountains. I have always seen tons of heavy used game trails and old mine roads that are to washed out to take even an ATV on. I need something that is light enough to carry over/thru difficult obstacles yet has enough power to help me up the steepest of hills. So low gearing will also be a must. Any advice would be very appreciated. I want to stay away from friction drive systems do to their poor performance in wet conditions. I also want to retain my disc brakes. Thanks and look forward to figuring this one out.
