I use the SBP shift kit and my bike had 5 gears on the rear. Even with that it was still geared a little low. I went with the 11 tooth counter sprocket and was better. Today I got the idea to use the 3 front chain rings from the bike I took off to do the shifter kit. 2 of the chain rings are bigger than the one on the shifter kit. I drilled them and installed on front. The biggest made 1st gear like 5th gear. I could cruise at 30mph in 1st. 1st-3d gears worked but 4-5th were too high and it wouldn't accelerate in them. 30 mph at idle. Went to middle size gear and perfect. 25-30 mph a little above maybe 2k rpm, just loafing along.
