To add to what T-Mar said also the early safteys did not have standard wheel size.wheels were often 28 rear and 32 front---smaller than the hi-wheelers but still large.Also many used pegs on the front fork to to rest the feet while"coasting"Frame sizes I think did run a bit large too as I've seen 26" and larger frame seven after the wheels were somewhat standard(28 or 26)
