  Amped A18 Comp 800W Electric Bike

  The Amped A18 Comp is the flagship 18” electric bike in the Amped range and one of the most capable 18-inch kids electric bikes currently available in the UK.

  Built for confident young riders who are ready for a serious step up, the A18 Comp combines a 36V 800W motor, 1000W peak output, full suspension, hydraulic brakes, a lightweight 6061 aluminium frame and 18” Duro fat off-road tyres.

  This is not just a faster balance bike. The Amped A18 Comp is designed to feel more like a small electric motocross-style bike, giving riders better suspension control, stronger braking, improved grip and much more confidence across grass, dirt, gravel and off-road terrain.

  For riders around 120–150cm tall, the A18 Comp is the premium choice if you want the ultimate 18” electric bike rather than a standard entry-level model.

  My Take as a British MX Rider

  The A18 Comp is the 18” bike I would look at when a rider has outgrown the feel of a standard electric balance bike and is ready for something much more serious.

  The big difference is not just the speed. It is the chassis, suspension and braking package. The full suspension setup, hydraulic brakes and fat off-road tyres make the bike feel far more planted and capable than most normal kids electric bikes.

  Compared with a Revvi 18, the A18 Comp is the more premium, performance-focused option. The Revvi 18 is a brilliant all-round electric bike, but the A18 Comp is the one for riders who want the flagship 18” machine.

  If your rider is taller or you want more room to grow, compare the A18 Comp vs A20 Comp before you buy.

  If your rider fits the sizing and wants the best 18” electric bike we sell, the Amped A18 Comp is the standout choice.

  Why the Amped A18 Comp Is the Flagship 18” Choice

  The Amped A18 Comp sits above standard 18” electric balance bikes because it is built around a much more serious performance package. It is aimed at riders who are already confident and want more suspension, more grip, stronger brakes and a more capable chassis.

  Flagship 18” Model

  The A18 Comp is the top 18” Amped bike, built for riders who want premium performance rather than a basic starter bike.

  1000W Peak Power

  The 36V 800W brushless motor delivers strong, responsive power with up to 1000W peak output.

  Full Suspension

  Hydraulic adjustable front forks and FASTACE rear air shock help the bike stay controlled over rougher ground.

  Hydraulic Brakes

  XOD hydraulic brakes front and rear give the rider stronger, more controlled stopping power.

  18” Fat Off-Road Tyres

  Duro fat tyres give extra grip and stability across grass, gravel, dirt tracks and woodland terrain.

  Premium Aluminium Frame

  The 6061 aluminium frame keeps the bike strong, stable and properly built for progression.
