jonathon – is yours coming up 4 or coming up 5?
It was the gearing as much as the wheel size
Yeah, my son’s 16″ bike is 22-16 for our hilly trails (and he was still only 2 when it was built) so top speed is slightly lacking. Planning to put a bigger chainring on, and longer cranks.
FunkyDunc – A second hand Beinn Small I was watching on ebay went for £215! Another for £175. I don’t think there are any other 20″ bikes that are as small framed as the Islabike, but I would be delighted to be corrected!
