The Best 18 Inch Electric Balance Bike

If you are shopping for an 18 inch electric balance bike, the revvi 18 is the clear pick. It delivers proper big-kid performance in a light, confidence-building package that is ideal as an electric balance bike for an 8 year old who is ready to step up. Available in six colours: blue, black, pink, green, red, orange. The revvi 18 brings real dirt-bike vibes with simple controls and serious components.

Why The Revvi 18 Stands Out

  • Proper progression for older kids - With three speed modes (Low, Mid, High), kids can start slow and build confidence before unlocking top performance.
  • Serious performance in a kid-friendly package - A 500w brushless hub motor gives strong, smooth acceleration without overwhelming new riders.
  • True off-road capability - Hydraulic front fork and rear air shock let kids tackle dirt tracks and uneven terrain, not just flat parks.
  • Premium stopping power - Hydraulic front and rear disc brakes deliver safe, controlled braking even at higher speeds.
  • Light but tough design - Aluminium frame and swing arm keep weight low (around 20 kg) without sacrificing durability.

Built For Riders Aged 8 Plus

With its three speed modes, stable 18 inch wheels, and predictable throttle, the revvi 18 helps riders master balance and control before progressing to larger e-bikes or petrol dirt bikes. It is the sweet spot if you are searching for an 18 inch balance bike that still feels playful but has room to grow.
