Brake levers sized for smaller hands

The Tektro HD-J2820 brakes have short-reach junior levers. They help your child reach the controls without having to stretch as far. Check that both levers can be reached comfortably and practise braking on familiar ground before the first trail ride.

Set the air fork for your child

The X-Fusion RC32 air fork has 130 mm of travel. Its spring pressure can be adjusted for your child’s weight, following the fork’s instructions and pressure limits. Have a workshop help with setup, and use a suitable shock pump.

One shifter for changing gradients

The nine-speed Shimano Cues drivetrain uses an 11–46T cassette. There is one chainring at the front, so your child has one shifter to learn. A 30T chainring and 155 mm cranks complete the drivetrain.

Check the fit, not just the height range

The suggested rider height is approximately 140–160 cm, with a 531 mm effective top tube. Check that your child can stand over the frame, reach the 710 mm bar and operate the brakes. Body proportions and experience matter alongside height.

The mini-mullet wheel setup uses a 27.5-inch front wheel and 26-inch rear wheel. Kenda Amrak 2.4-inch tyres are fitted to Raptor rims. The rims are tubeless ready; any conversion also needs suitable tyres, tape, valves and sealant.

An adult should check the bike before each ride, choose routes suited to the child’s ability and help with protective equipment. Candy pedals are included. The listed weight is approximately 13.50 kg.

Inspect the bike after a hard impact and stop riding if you find looseness, cracks or damage. Have any problem checked and repaired before riding again.

Wear a properly fitted helmet and suitable protective pads. Read our important information before buying and using a bike for assembly, servicing and riding checks.
