I wasn't sure if I should post this in classic bikes or here.
I found a classic Ralleigh 3-speed bike. It is a kid's bike with 24" wheels. I can fit on it, maybe a couple more inches of seat post would help. But the cranks are quite short, making for a difficult ride.
The cranks appear to be bolted on and so I thought perhaps I could replace them if I could find some cranks that could bolt in the same way.
My question is, if I put longer crank arms on, would the bike become unsafe to ride? Would I risk snagging the pedals when I rounded corners? How much clearance does there need to be between the pedal in the down position and the ground? Or am I worrying needlessly?
