Re: Looking for a sporty motorized bicycle
"extreme lean angles" is kinds tough to get out of a bike with an average top speed of 40mph and skinny bicycle tires (compared to wide m/c tires. )
a lower center of gravity, lower seat, lower bars, etc are needed, and you won't find that on a walmart bike.
check out the racer's bikes on here, and find the youtube videos of our races and you'll see the limits we have now.
you'll never get anything close to the handling or speed of a m/c unless you build something yourself that pushes the limits of a motorized "bicycle."
check out jeff's bikes (culvercityclassics) and scotto's for something closer to a motorcycle. they ain't cheap or easy to build, obviously...
