hi everyone i am in the process of installing my first engine. isnt this neat?!?
49cc zoom bikes trek liteweight mtn bike. should have it running in a week or to. yabba dabba doo. had an electric kit. was great except it increased the weight of the bike by 65 lbs, top speed was only 19mph, and only went 10 mph or above for 10-12 miles. then 5mph for another 5mi. stopped working and now for sale motor only. recharging took 4-5 hours, and cost about a dollar each recharge.
anyways can someone tell me the advantages of a 4-stroke engine? faster? more than one gear?
