brushed vs brushless. Is the drag on brushed motors so bad that you have to run it all the time? 200 bucks more for brushless is it worth it?
To help charge the battery and increase range. I was thinking of mounting a car alternator to the frame. Using one of those sprockets that attach to the spokes to drive it. I think will be turning in the opposite direction as it does in a car. Would it make charge going backwards? If not, I think I can work out a way to get it rotating the right way. As for the speed, with a 14T sprocket on the alternator and 50T the one on the wheel, at 20 mph it will turn at about 900 rpm. With a custom 80T it will turn at about 1500 rpm. Do you think this would be fast enough to produce a significant charge? Keep in mind when the alternator is going 2-3x faster than the engines rpm when in a car.
When I was trying to find out more about brushed vs brushless, I ran accros this thread http://www.motoredbikes.com/showthread.php?t=6444&highlight=brushed+brushless. I dont really get why he even needs the gas engine. Just hook up th generator part of it the way I'm talking about with the alternator.
HOLD ON! That belt drive bike just caught my eye. http://www.bikeengines.com/bentest.htm That large "pulley" on the rear wheel should provide adequate rpm's for the altenator or Just for Kicks's generator. You'd think anyway. Wonder if they sell that part separately.
Well it getting late.
Thanks in advance!
