Why choose the Revvi 20"?
The Revvi 20" is built for older, more confident riders — offering more power than the 18" while keeping the same smooth, controlled ride with full suspension and hydraulic brakes.

Designed for riders aged 10+, it delivers 22mph of top-end performance in a 22.5kg package that is still light enough to handle with confidence. If your rider has outgrown the 18" or is stepping into the Revvi range for the first time at 10+, this is where they belong.

Three Speed Settings. Real Room to Grow.
The Revvi 20" gives riders a clear progression path through three speed modes:
- Slow — 10 mph — confident, controlled riding for those finding their feet
- Medium — 16 mph — the natural next step as skills and confidence develop
- Fast — 22 mph — full 800W performance for experienced, capable riders
The full twist throttle with integrated battery level display keeps control intuitive, while alloy adjustable-reach brake levers are designed to suit a range of hand sizes comfortably.
Speeds may vary depending on riding conditions and rider weight.
Full Suspension. More Travel, More Capability.
The Revvi 20" steps up the suspension over the 18" with increased front fork travel, making it more capable on demanding terrain:
- Front — Suspension forks with 100mm of travel
- Rear — Air shock at 140psi with 30mm of travel
Together with aggressive knobbly 20" tyres on spoked rims, the Revvi 20" handles everything from grass and gravel to dirt tracks and off-road trails with composure. The aluminium alloy frame with swingarm keeps the whole package rigid and responsive without adding unnecessary weight.
Hydraulic Disc Brakes — Front and Rear
At speeds up to 22mph, reliable braking is non-negotiable. Hydraulic disc brakes front and rear deliver strong, consistent stopping power in all conditions the bike is designed for — giving riders the control to push harder and parents confidence in the safety of the setup.
Extended Battery Life
The removable 36V 7.5Ah lithium battery is a step up from the 18" and reflects the demands of older, more active riders.
Charge time is 2 hours 30 minutes, with the following approximate ride times by speed setting:
- Slow — approx. 90 minutes
- Medium — approx. 60 minutes
- Fast — approx. 35 minutes
Looking for Alternatives?
If your rider is slightly smaller or still building confidence, the Revvi 18" is often the better starting point.

Is the Revvi 20" Right for Your Rider?
Designed for riders aged 10+, with an adjustable seat height of 68.5–86.5cm and a maximum rider weight of 65kg.
The wide seat height range suits a broad spread of riders in this age group. Suitability always depends on the individual child’s height, weight and skill level — at the parent’s discretion.
What's in the Box
The Revvi 20" arrives semi-assembled — the front wheel, number board and handlebars require fitting, while the throttle and brake lever come pre-fitted to the bars.
Each bike includes a UK charger, owner’s manual and tool kit.
Assembly requires a mechanically capable adult. Please ensure all bolts and components are correctly tightened and lubricated before first use.
