So I finished my 49cc Tri Rider yesterday and not surprisingly there is no low end power. I'm running a 11T drive sprocket and a 24T on the axle. (4" diameter) I know it's small, but there are three support bars in the way and the max diameter sprocket I can squeeze in there is a 5.5 inch which I don't even want to try because the improvement wouldn't even be worth the trouble. The only thing I can think of is to build a 10" mini axle off of the back with two sprockets (44T & 20t) and then back to the original axle. Any advice would be greatly appreciated. I only need about 15-20 mph top end. Just tool around the neighborhood with my dog and need to be able to climb medium inclines. Thanks.
