Revvi 18" Electric Bike ā Quick Overview
Recommended age: approximately 8ā11 years.
Best for: confident riders moving beyond smaller 16-inch electric bikes.
Rider fit: typically suited to riders around 130ā155cm, with an adjustable 67ā74cm seat height.
Motor: 36V 500W brushless hub motor.
Speed settings: 9.5mph, 13.5mph and 20mph.
Our view: the Revvi rangeās strong all-round step-up bike, combining a bigger chassis with full suspension and hydraulic braking.
The Revvi 18 is designed for older or taller children who are ready for a more substantial electric bike. Its 18-inch wheels, adjustable seat, 500W motor and 20mph top setting provide more room and stability than the smaller Revvi 16 models.
Full suspension and hydraulic disc brakes make it capable over rougher ground, while three speed settings allow performance to be introduced gradually according to the riderās ability.
My Take as a British MX Rider
The Revvi 18 feels more like a proper electric motorbike than the smaller balance-bike models. The larger chassis, suspension and hydraulic brakes are meaningful upgrades for riders who are becoming faster and more confident.
For most riders stepping up from a 16-inch bike, the Revvi 18 is the best all-round size-and-performance choice.
Get More Value with a Revvi 18 Bundle
For a rider moving onto a faster bike, the bundle options are well worth checking before ordering. Depending on availability, they can combine the Revvi 18 with protective riding gear or additional battery capacity for longer sessions.
Choose a gear bundle if the rider still needs the main protective equipment. Choose an extended ride-time option if fewer charging breaks matter.
Why Choose the Revvi 18?
500W Power
The 36V brushless motor provides strong performance for confident step-up riders.
Bigger 18-Inch Platform
More physical room and stability for riders who have outgrown smaller Revvi models.
Full Suspension
An 80mm front fork and air rear shock improve comfort and control on uneven terrain.
Hydraulic Brakes
Hydraulic discs with adjustable-reach levers provide consistent stopping performance.
Is the Revvi 18 Right for Your Rider?
The recommended age is approximately 8ā11 years. Age alone does not confirm fit: rider height, inside leg, reach, confidence and experience should all be considered.
Choose the Revvi 18 If...
- Your rider is approximately 8ā11 years old
- They have outgrown the 16-inch Revvi models
- You want a stable all-round bike with full suspension
- A 20mph top setting suits their ability
Consider the Amped A18 Comp If...
- You want a premium 18-inch performance bike
- The rider needs more power and higher-spec components
- They regularly ride tracks, fields or rough terrain
- Performance matters more than value
Consider the Revvi 20 If...
- Your rider is taller or needs more room
- You want a larger Revvi platform
- Physical size is the priority rather than a premium upgrade
- The Revvi 18 riding position appears cramped

Revvi 18 FAQs
What age is the Revvi 18 for?
The recommended age is approximately 8ā11 years, subject to rider size, confidence and ability.
Should I choose the 18 or 20?
Choose the 20 when the rider needs a larger physical platform; choose the 18 when its adjustable 67ā74cm seat height provides the better fit.
Why choose a bundle?
Bundles can provide better value when the rider also needs protective gear or additional ride-time options.
Can it be used in wet conditions?
No. The supplied guidance states that the Revvi 18 is not suitable for wet conditions.
Our Verdict
The Revvi 18 is a strong all-round step-up bike, offering a larger platform, full suspension and hydraulic brakes without moving straight to the premium Amped A18 Comp.
For a confident rider aged approximately 8ā11, check the Revvi 18 bundles before buying the bike alone.
