since i built the 2 lowriders, i haven't riden any of my other bikes. they both are driven on a daily basis. as a matter of fact they get all over town.
for long rides i take the second lowrider. it has a sturmey archer 3 speed internal hub. the other is more for cruisin the hood (to and from the store etc) the small childs crank makes it easy to pedal, but to gain any real speed ya got to pedal your heart out.

its a different experiance. with the bike this low i can reach top speed, lean the bike on its side and use the pedal for a brake (grinding it into the ground) without risk of crashing.
upon rare occasion i bottom out the bike or hit the pedals on the ground. that being said, the only way you know ya did it is cause ya hear it. ya really dont feel it. its not like hitting your pedals on the ground on a standard bicycle.

both bikes navigate most curbs manholes etc with ease. the only time i seem to bottom out the bike is on speed bump type surfaces.
