Cobra 24

A great first mountain bike...

We don't know where it comes from, but your kid's undying love of dirt is a common — and treatable — condition. The Cobra 24 can help. It's a great first mountain bike, helping to bridge the gap to adult bikes. The 24-inch wheels roll over obstacles without being too big to handle, and 21 gears and a suspension fork allow small riders to conquer dirt trails. With a durable steel frame and tough wheels, it's the cure for satisfying your little dirt maniac. This model fits riders 53”-62” tall, aged approximately 8-12 years old.

  • DB Hi-Ten steel frame
  • Shimano 3x7 speed drivetrain
  • HL Zoom 40mm travel fork
  • Linear pull brakes

However, others say that it's a little small for a 24" bike, has missing parts, and is poorly fitted. The length of the bike is shorter than most, so your feet do hit the front.

Absolutely do not buy this bike!
1 Star
Absolutely do not buy this bike!
The pedals are dangerously close to the front tire when properly assembled. Don’t think twice about going back to your search results and finding a different bike for your child. My 9 year old son immediately noticed how his foot hit the front tire and got right off. I wouldn’t want other parents to experience the same disappointment I did. I contacted customer service for DB and they approached the design flaw with the delusional approach of continuing to ask for additional photographs and never accepting responsibility or offering to remedy the situation. This is the only negative review I have ever written for a product. Avoid the disappointment and select another bicycle to ensure your special day goes off without a hitch. From one parent to another…
