Read this on another forum "Also the gears they push, basically with smaller wheels and bikes well designed for small people they are putting less force thru the knee and this is very important for immature humans"
Now I don't know much about gear ratios etc but in my experience it takes more force to pedal a bike with smaller wheels over the same distance/terrain, than one with larger - thinking of the difference for my son on 12" compared to 16".
The question on the forum I was reading was whether someone should get a 16 or a 20 for their small 5 year old. I agree that 16 would probably do him best as it is a first proper bike, but wasn't sure that the "less force through the knee on smaller wheels" is correct.
Can someone more knowledgeable agree or disagree and explain why?
