About the Manufacturer

Producing some of the most popular and visually recognizable scooters in the country, Razor has been credited with the recreation of the scooter craze in the USA. Starting with the original kick scooter, Razor has used its distinctive patented single lever folding system and rear fender brake through the evolution of their kick scooters.

Each scooter is constructed of Aircraft-grade aluminum to provide maximum durability without weighing the rider down. Features such as the foam grip handlebars and durable grip tape are engineered to achieve a system that allows riders to utilize every inch of their scooters. In 2000, the ever popular A Series Kick Scooter won the coveted Toy of the Year award.

Along with an excellent class of kick scooters, Razor produces a line of electric powered toys ranging from stand-up and sit-down scooters to realistic motocross bikes and go-carts. Entertaining age groups as young as toddlers up into teenage years, there is a Razor for just about everyone.

Razor also has Team Razor, the company’s extreme sports team that highlights the abilities of young riders with various Razor products, most notably kick scooters. Team Razor demonstrates the capabilities of Razor products in a safe environment, reinforced by the company’s safety tips and precautionary designs.

from Mount Pleasant, SC – Verified Buyer

The bike seems OK, but we got what it was obviously a returned item, so we are missing several parts. I am use to buy online (made more than 30 purchases just from Amazon last year) so this kind of things can happen, someone forgets to put something in the box, small hardware parts get lost in transit, etc. What I can not understand is how Wayfair ships again an item that was probably retuned because the same issue we are having. This was my second experience with Wayfair, and probably my last. As for the bike, who knows if it'll work…..

Dont waste your money!!!

from Eastlake, OH – Verified Buyer

This bike looks great. It arrived without a kickstand. called the manufacturer. NO Help at all. The bike is made very poorly. the chain keeps coming off and the pedals are made of cheap plastic. One has already broken.My son was so excited to receive this for his birthday in August 2013, only to be let down right away. Don't disappoint your child. look for another bike.

This BMX bike is so cool! I love it! Everything works great and exceeded my expectations. Wayfair was an easy site to purchase from and my bike was shipped on time. My family will definitely be back for more! Thank You. Ollie (and his Grandpa)
