    I intended to go very slowly, but I find myself going faster than I would have thought. I'm curious about the rest of you.

    To make it quick, how about this format? Suggestions are welcome.

    Assuming acceptable weather and road conditions;

    Bike: cruiser
    Engine size: 49cc
    Drive type: factory gearbox, chain
    Load weight: 200lb (you, your gear etc)
    Terrain: mostly flat, asphalt
    Area: in town
    Average speed: 15mph
    Max speed: 26mph

    Wow. I'm surprised how close all those speeds are to each other. I like the addition of the 'max speed' line!

    Three miles an hour gained by swapping a sprocket, you gotta love it. Congratulations!

    I'm looking to optimize the gearing to run in the engines sweet spot at my normal cruising speed. (about 20-23mph) Looks like this will turn the trick!

    Bike: Mountain Bike
    Engine size: 66cc China Girl
    Drive type: Chain, 36T sprocket
    Load weight: Around 155 lbs / 70kg
    Terrain: hilly, flat, bridges, all asphalt/concrete
    Area: surburban
    Average speed: 45 kph / 28 mph (flat) and 29 kph / 18 mph uphill.
    Max speed: 58 kph / 36 mph

    My 'idling speed' (where it will put along with no throttle at all on flat ground) is around 30-33 kph/18-20 mph.

    I have had it to 68.9 kph / 42.etc mph coming down the bridge, but that's where the bike itself began a speed-wobble beneath me, so I had to cut the throttle and let it settle down a bit.

    Your idling speed is my average:) I understood that an engine should not be idled high enough to propell the bike?

    Great! So far our weight on the tyres is: 275lbs, and we ride at: 25mph. Knowledge is power, and there's alot more here.
    Let's get as many members as possible to give their feedback here. Then we can talk about braking and other issues with some mathematical info.

    Thanks for the help!.we..wee.brnot
