Sprocket size for a little guy w/ a 70cc HT

I'm looking to bring the noise down and fuel economy up when cruising at 25, via a smaller sprocket.

I weigh about 130lbs and my bike w/motor weighs 55lbs.

How does a 30 tooth sprocket sound?

you might have to pedal a bit to get started
a 36 would be less pedalling
andyinchville could give better advice (he sells sprockets...see ad on left side of page)

I purchased a 36T from him and I will say, You pay for what you get. And what you get is a really nice American made sprocket. I love mine. I have to let the clutch out more gradually, but that's fine.

I'm thinking a 32 tooth sprocket, need new brake pads first though. How good are These pads from delta.

Thanks

HI Guys,

Thanks for the kind words....As far as going to a 30T sprocket....If you are in a relatively flat area, live at not too high an altitude, and plan on not having a lot of stop and go or slow speed operation....a 30T should be OK....I have sold as low as 27T to a group of people in FL and they seem to be fine with it (First one man bought a 27T then later all the guys friends also bought some from me....I guess that had to try to keep up with their buddy and his small sprocket!)...

FWIW and if you want to save a few $$....Our best sellers are 34T sprockets and they typically sell on eBay for around $20 or so.


Hope this helps you. Good luck in your build and ride safe!

Andrew

The Florida guys is a case were bigger isn't better.

Thanks for your help.

I'd try Kool Stop Salmons before I'd use the Azteks on a motorized rig.

They are good pads and work great on my 23 lb. hardtail but they weren't up to repeatedly bringing my 50 lb. commuter with a rack and panniers to a stop at the bottom of a 40 mph hill. After a while they glazed over and now they squeal like a pig.

I'll try the Azteks, then switch to the more durable Kool Stops if the delta Azteks don't work out.
I'm also use to squealing brakes.

You should consider getting one of those neat shifter kits I just read about. I gotta get one of those but don't have the money as of yet.

I've got the money for Paul's kit but would rather spend the money on school.
