Powered by a 36V 500W brushless hub motor, the Revvi 18” offers three selectable speed settings, reaching up to 19 MPH in its highest mode.

🏁 Three Speed Modes. One Bike That Grows With Them.

The Revvi 18” gives riders three speed settings, allowing the bike to be matched to their confidence and experience.

🐌 Slow — 9.5 MPH

A more manageable setting for riders getting used to the bike and developing throttle control.

⚡ Medium — 13.5 MPH

For riders who are becoming more confident and want to start exploring the bike’s performance.

🚀 Fast — 19 MPH

For experienced riders who are comfortable with the bike and ready to use its full performance.

Always select the speed setting appropriate to the rider’s ability and supervise children while riding.

🛞 Built For Off-Road Riding

The Revvi 18” is designed to handle much more than a smooth garden or driveway.

🏁 Full Suspension

Hydraulic front suspension with 80mm of travel works alongside the rear air shock with 30mm of travel to help absorb bumps and uneven terrain.

🛑 Hydraulic Brakes

Hydraulic disc brakes front and rear provide strong, controlled stopping performance.

🛞 18” Knobbly Tyres

The aggressive pneumatic tyres provide grip across a variety of off-road surfaces.

💪 Aluminium Frame & Swingarm

The lightweight aluminium construction keeps the bike manageable while providing a strong platform for off-road riding.

🏍️ MX-Style Details

Foldable MX-style foot pegs, adjustable handlebars, an adjustable seat and a metal-spoked wheelset give the 18” a proper mini motocross feel.

🔋 Battery & Range

The Revvi 18” comes supplied with a 36V 5Ah removable lithium-ion battery.

Approximate continuous riding times:

🐌 Slow — up to 1hr 20min

⚡ Medium — up to 45min

🚀 Fast — up to 25min

Actual riding time will vary depending on speed setting, rider weight, terrain, riding style and conditions.

The battery is removable and can be changed in around one minute, while the bike also features an external charging port for convenient charging without removing the battery.
