Great wee bike. My boy has just turned 7 years old and loves it. Age range in my opinion is 7-11. The minimum 13yr old age recommended on the write up and box is ridiculous. No 13yr old could ride, or would want to ride this as would be far too small and slow.
Build quality on bike is very good and is super easy to operate.
Only thing I think it should have is a progressive throttle. The on off grip throttle is a little annoying as it's full power or nothing. Just something to get used to but not a big deal.
Would buy another Razor product based on this.
Thanks.
