Lucky for me, I happen to be 6'-3" with long legs and the few people that have brought up lending them a bike were shorter. I would explain to them about frame sizing and crank arm dimensions, and seat height, and triple chain ring shifting, and blah, blah, blah. "Never mind." The very best one though was a guy at work that complimented me on my health at an advanced age. He was thinking maybe about taking up bike riding too. "Have you seen what a good bike is costing now days?" he asked. "You can drop three to four hundred dollars on a new bike!" "Maybe I could try out a few of yours to see what I like. Walmart won't let you just try them out in the parking lot!" I brought up our height difference, and seat placement, and.........closing with noticing lots of bargins on Craig's list lately. I retired last summer and have yet to see him out on the local trails. Must not have found the right color grips yet.
