Overview

Razor puts a steel frame and fork, BMX-style handlebar and training wheels on the Kobra, a single speed kids bike for neighborhood riding. A foot coaster brake and a front hand brake handle stopping.

Two brakes and training wheels make it a confidence builder for a child learning to ride on pavement. The steel build adds heft, and the listing gives no rider weight limit.

Who it's for

Made for kids who have reached the minimum height and ride on paved paths. Older or taller children who need gears should look at a larger bike.

Pros and cons

Pros
  • Steel frame and fork
  • Two brakes, hand and coaster
  • Training wheels included
  • Long frame warranty
Cons
  • Rider weight limit not stated
  • Single speed only
  • Steel adds weight

Performance notes

Pedaling backward engages the coaster brake, while the hand brake adds front stopping for kids ready to use it. A single gear makes riding simple on flat paved streets but makes hills harder.
