I haven't measured the cranks, but it was on a 15" Trek 920 as shown below.
I was looking for an eight speed rear wheel on craigslist (for a different bike) and found a set of what turned out to be pretty good wheels with an 8-speed cassette and the tubes and tires and some cool anodized red skewers too, all for $30 on craigslist. And, it was right on my way home from work that day. Naturally I bought the $30 wheelset and took the "free" tires. We put them on my son's bike and he tried them out on the street in front of the house and in the two nearby cul-de-sacs. I saw him hit a pedal on the ground right away and he did it some more while turning around in the cul-de-sacs.
It could be okay with an alert rider who always raises and keeps the inside pedal up when cornering, but they're not suitable for a kid who ought to be able to ride without such worries, as he could with the 2" tires. I didn't bother to try them on my 26" MTB after seeing what happened to him. I'm glad I found that wheelset, though.
