A small frame for the first BMX rides

The Revo pairs 14-inch wheels with a 13.7-inch top tube and 102 mm one-piece chromoly cranks. Its full 1020 Hi-Ten frame has 10.55-inch chainstays, while the complete bike weighs approximately 8.825 kg.

Check fit and brake reach

The suggested rider height is around 95–115 cm. Check body proportions and riding ability as well as height. Top tube length is a frame measurement, separate from wheel diameter.

The bar measures 6.5 inches high and 22.4 inches wide. Make sure the rider can reach it and operate the brake comfortably. An adult should check the setup and choose a practice area suited to the child’s ability.

Adjust the saddle for your child

The railed Century saddle and 250 mm aluminium post allow position and height adjustment. Stay within the rail adjustment limits and the post’s minimum insertion mark, then check the clamp and fixings are secure.

A front caliper and rear V-brake are fitted. Have them adjusted before the first ride and check their operation before every session. The headset, US bottom bracket and hubs use loose-ball bearings; keep them inspected and serviced.

Get used to the cassette drivetrain

The 25T steel sprocket and 9T cassette driver provide a single-speed setup. The cranks turn when the bike rolls backwards, unlike a freecoaster. Practise in a suitable area under adult supervision.

Safety while riding

Freestyle BMX riding puts high loads through the bike during tricks, jumps and landings. No bike is indestructible: parts can wear out or become damaged. Check the frame, fork, bars, wheels, axles, cranks, pedals, brakes and bolted connections before every ride. 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 riding a BMX bike for assembly, servicing and riding checks.
