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

The Revvi 20” gives riders three selectable speed settings, making it possible to match the bike’s performance to their confidence and experience.

🐌 Slow — 10 MPH

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

⚡ Medium — 16 MPH

For riders who have gained confidence and want to start exploring more of the bike’s performance.

🚀 Fast — 22 MPH

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

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

🛞 Built For Off-Road Riding

The Revvi 20” is designed to cope with much more than smooth surfaces.

🏁 100mm Front Suspension

The front suspension provides 100mm of travel, helping absorb bumps and uneven terrain.

💨 Adjustable Rear Air Shock

The rear air shock provides 30mm of travel and can be adjusted to suit the rider and riding conditions.

🛑 Hydraulic Disc Brakes

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

🛞 20” Knobbly Tyres

Large 20” pneumatic off-road tyres provide grip across a variety of terrain.

💪 Aluminium Frame & Swingarm

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

🏍️ MX-Style Details

Foldable MX-style foot pegs, an adjustable seat, height-adjustable handlebars and spoked wheels give the 20” a proper mini motocross feel.

🔋 Battery & Range

The Revvi 20” comes supplied with a 36V 7.5Ah removable lithium-ion battery.

Approximate continuous riding times:

🐌 Slow — up to 1hr 30min

⚡ Medium — up to 1hr

🚀 Fast — up to 35min

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

The battery is enclosed within the bike’s metal frame and can be changed in approximately one minute.

The battery also features its own charging port, allowing it to be charged on or off the bike.
