The Mongoose Cipher is the perfect bike for developing the riding skills of your kids and learning how to ride a  multi-speed bike. This bike is built with every feature that kids need to ride and nothing they don't, ensuring they can get the most out of the Cipher. The tough and lightweight aluminium frame and fork combo get the job done every time and are light enough to allow you kids to control the bike with ease. The simple gearing and larger tyres which improve comfort make this bike fun to ride so that they'll really want to go for a bike ride. The Cipher is easy to control thanks to the coaster brake hub and front/rear v-brakes so that your kids can ride safely on any terrain. The Mongoose Cipher is a high-quality aluminium frame kids bike which is great for developing riding skills and getting outdoors on two wheels.


  • Mongoose Tectonic® T1 aluminum frame and aluminum rigid fork
  • Internal 3-speed hubs
  • Kenda® 1.75” tires and Nexus Inter3 with coaster brake hub and front/rear v-brakes.
