On "The Whizzard's" maiden voyage yesterday, I rode to my jobsite and back, then motored west to Home Depot for stuff, a distance of 25 miles. The bike performed flawlessly; this surprised me cuz I rescued it eight days ago from months of neglect in an open bike lot. Changed oil and crumbling fuel lines, tightened stem, added air and awayyy she went!:grin5:
Brakes need attention but that's another post.
My question is if it's possible to change to a smaller sprocket on single-speed bikes. This Whizzer is freewheeling; it has a small drum brake, not a coaster brake.
However, I'd also like to swap to a smaller sprocket on "The Dragon Lady", my twin-engined cruiser with coaster brake.
The reason is that both bikes need my pedal-assist during midrange and top speed. My other dual-engined monster "The Iron Dragon" has five speeds and fifth gear REALLY helps pull the bike, even at speeds over 30mph
What should I look at changing, the freewheel sprocket or the crankset?
IMO, adding more pedal-assist to a Whizzer bike or a motorized coaster bike would definitely enhance both bike's midrange and top end performance.
Of course low speed pedalling would suck without the engine , but I can live with that.
