Three Speed Settings. Real Progression.
The Revvi 18" gives riders — and parents — three clearly defined speed modes to grow through:
- Slow — 9.5 mph — perfect for building confidence and learning control
- Medium — 13.5 mph — the next step for riders developing their skills
- Fast — 20 mph — full performance for experienced, confident riders
Speeds may vary depending on riding conditions and rider weight.
The full twist throttle with integrated battery level display keeps everything simple and intuitive, while alloy adjustable-reach brake levers are designed to work comfortably with younger hands.
Full Suspension. Proper Off-Road Capability.
Unlike balance bikes that offer basic front forks, the Revvi 18" features a full suspension setup front and rear — making it genuinely capable on rough terrain:
- Front — Suspension forks with 80mm of travel
- Rear — Air shock at 140psi with 30mm of travel
Paired with aggressive knobbly 18" tyres on spoked rims, the Revvi 18" handles grass, gravel, dirt tracks and off-road terrain with confidence. This is a bike built for adventure, not just the garden.
Hydraulic Disc Brakes — Front and Rear
At speeds up to 20mph, stopping power matters. Hydraulic disc brakes front and rear deliver strong, progressive braking performance in all conditions — giving riders the control they need and parents the reassurance they want.
Lightweight and Rider-Friendly
At just 20kg, the Revvi 18" is impressively light for a bike with this level of specification. The aluminium alloy frame with swingarm keeps the weight down without compromising rigidity, and foldable MX-style foot pegs add to the authentic motorbike feel.
The adjustable seat height of 67–74cm suits a wide range of riders in the 8–12+ age group.
Battery and Range
The removable 36V 5Ah battery charges in under 2 hours and delivers the following ride times depending on speed setting:
- Slow — approx. 80 minutes
- Medium — approx. 45 minutes
- Fast — approx. 25 minutes
Please note: Not suitable for use in wet conditions.
What's in the Box
The Revvi 18" 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.
Is the Revvi 18" Right for Your Rider?
Designed for riders aged 8–12+, with an adjustable seat height of 67–74cm and a maximum rider weight of 50kg.
Suitability always depends on the individual child’s height, weight and skill level — at the parent’s discretion.
The Revvi 18" is a great choice for confident young riders stepping up into a proper electric motorbike.
