Now the hugely popular "Fat Bike" is available for younger riders! Fat Bikes are capable of riding over soft terrain such as sand, bogs and snow thanks to the incredibly wide tyres and rims. Fat Bike tyres can be run at much lower pressures than a standard mountain bike, allowing much more traction on even the muddiest of terrains. The Sonic Bulk features super-oversized 20 inch wheels, and will suit riders in the age range of 6-12 years old. The bike is equipped with Shimano gears, and has six wide range mountain bike gears to help you get across any terrain, or just for an easier ride to school. The gears are controlled by Shimano Revo shifters. Quality V-style brakes are fitted offering large amounts of modulated braking when it's needed.
