Kids Fat Bike

A bike designed for young riders that aren’t afraid of any terrain introducing our 20-Inch Fat Bike. Massive 20-inch by four-inch off road “fat” tires and slick 7 speed drive-train, they can tackle any terrain that they dare. Fat bikes are perfect for sand, snow and everything in-between. The Sun M30 thumb shifter make changing gears easy, whilst front and rear disc brakes provide awesome stopping power in wet or dry conditions. The 6061 Alloy frame style makes this bike a lot later than the other models out there, coupled with alloy components for a bike that comes in at under 30 LBS, we even drilled out the alloy rims!  This fat tire bike is super fun and will build confidence in every rider.

  1. 5 out of 5

    No better deal out there! This bike is built with a very smart component set that does a great job of balancing weight and price. All of the other 20″ fat bikes on the market that come close to matching the weight of this bike are significantly more expensive and not any better. The build is so good on this bike that it weighs about the same as a typical 24″ kids bike. With the fun factor and versatility of having fat tires on a well built bike you can’t go wrong buying this for your little ripper! My daughter has never been so excited about a bike!
