Which Revvi is right for your child?

Choosing a Revvi starts with the rider: their size, balance and confidence. Use this comparison to narrow down the range, then check the fit before buying.

Compare the Revvi range

Age ranges are manufacturer guidelines, not a guarantee of fit. Wheel size alone does not tell you how a bike will fit or how manageable it will feel.

*Manufacturer-listed specifications checked September 2026. Specifications can vary by model year; confirm the supplied version with us. Revvi lists differing weights for the 24″, so an approximate range is shown. Battery capacity alone does not predict riding time.

What to check before choosing

Fit: check the rider’s reach to the ground, handlebars and brake controls. Ask us about a fit check if you are between sizes.
Control: the rider needs to manage the bike’s weight, balance, throttle and braking. A larger bike is not automatically the right next step.
Experience: start with unpowered practice where supported, then use the lowest powered setting when the rider is ready.

For the 12″ model, two-year-old riders should use it without power. Follow the bike’s age guidance and instructions. Children must be supervised by an adult and use suitable protective equipment. Plan riding on private land with the owner’s permission.

16″, 16″ Plus or 16″ XL?

The 16″ Plus adds front suspension and a rear disc brake to the smaller balance-bike format. The 16″ XL is a substantially heavier bike with front and rear suspension and hydraulic brakes. Compare the rider’s fit and control rather than treating all three as the same size.

20″ or 20″ Plus?

The Plus has a 48V 15Ah battery, adjustable suspension and more weight to handle. The standard 20″ uses a 36V 7.5Ah battery. Both have 20-inch wheels, but they are different bikes to ride and manage.
