Since then I have looked at the scooter and its specification and it looks that this scooter should be suitable for adult scootering. The new Razor scooter with 5.5 inch big pneumatic wheels is available a the Sharper Image . If you have one write to us and we will post your review. They may not have been designed with adults in mind. And remember if your are tall or mature or scooting on rough pavement you must go with a bigger wheel scooter like the Xootr or even a bigger wheels one.
Scooters share the same risks as bicycles.
Always wear a helmet, obey traffic laws and do not ride at night without highly reflective garments. About 6 weeks ago I was given a JD Bug scooter. It has a very soft ride compared to my original razor scooter with the 100 mm wheels and front suspension. It handles bumps in the pavement much better. However, the friction of the wheels makes it very tiring to ride over long distances.
