These were a blast when I was a child - I remember them as 'Flying Turtles" - and this model is even better. The wheels roll very well and the racer starts moving easily when the bars are swung back and forth. I purchased 2 of these racers from Pedal Car Planet last year for my church's youth camp and they were certainly a highlight - the kids are asking if the racers will be there this year, and the answer is 'YES' - the quality of these machines will provide many years of camp and other activity fun! Thanks Pedal Car Planet for great prices and service on many quality products!
