Yep, shift kits work well in my situation. I have a LOT of impatient car drivers around me in traffic, especially rush hour. If you're slow, especially from a standing start, they're quick to blow their horns.

To put the cassette's overall gear ratios into perspective,
first gear is like a Happy Time 89-tooth single sprocket;
second gear = 68t sprocket;
third gear = 60t sprocket;
fourth gear = 53t sprocket;
fifth gear = 45t sprocket;
sixth gear =40t sprocket;
seventh gear = 34t sprocket;
eighth gear = 29t sprocket.

So using a 40t HT sprocket is like pedal-assisting in sixth gear on a bike with a shift kit.

Shift kits are easier on the clutch too.
Sounds great thanks for the info. here, Ididnt know exactly how the gearing played out on one, I have 2 bikes that have 7 gears on the rear wheel instead of eight but I fih=gure if I dont like the 3 spd set up I'll just change over toone of them in its place and put a simple Derailleur on it off one of the other old bike I have sitting around or just get a new one from my Local Bike Shop.

Thanks again for the info.

I dont always ride WOT, but when I do..I do my best to keep the rubber side down..Ride safely my friends!
