Revvi 18: the next step from a smaller electric bike?
The Revvi 18 electric bike sits between the smaller 16-inch Revvi models and the larger Revvi 20. It combines a 36V 500W hub motor, full suspension and hydraulic disc brakes with an 18-inch wheel platform.
Usually considered for riders aged approximately 8–11 years, it is worth comparing when a smaller bike has become cramped and the rider is ready for more room and performance.
Revvi 18 at a glance
Best suited to: young riders who have developed throttle and braking control and need more space than a smaller electric bike provides.
Main features: 18-inch wheels, a 500W brushless hub motor, removable 36V 5Ah battery, three speed settings, full suspension and hydraulic brakes.
The key decision: does the rider fit the bike comfortably and have the ability to control it? Age alone does not confirm suitability.
Why consider the Revvi 18?
The Revvi 18 is a useful model to compare when a rider has outgrown a 16-inch bike but does not need the size of a Revvi 20. Its suspension and hydraulic brakes complement the larger chassis for recreational off-road riding.
A larger riding position
The 18-inch platform gives growing riders another sizing option between the smaller Revvi models and the 20-inch range.
Selectable performance
Three speed settings let you introduce performance gradually as the rider develops consistent throttle control, steering and braking.
Full suspension
Front suspension and a rear air shock help absorb uneven ground. Hydraulic disc brakes provide stopping control, with adjustable-reach levers.

What age and size is the Revvi 18 for?
The usual age guide is approximately 8–11 years, with an indicative rider-height range of 130–155cm. These are starting points, rather than a guarantee of fit.
Check the rider’s inside-leg measurement against the 67–74cm adjustable seat height, along with their reach to the handlebars and brake levers. Previous riding experience also matters.
Before choosing the Revvi 18, check:
- The rider can reach the ground securely at an appropriate saddle setting.
- They can comfortably reach and operate both brake levers and the throttle.
- They can start, steer and stop without struggling with the bike’s size.
- Their weight is within the limit shown in the product listing and supplied manual.
Unsure about sizing? Contact us with their height, inside-leg measurement and current bike so we can help you compare options.
Is it a suitable upgrade from a Revvi 16?
It can be, provided the rider is physically ready and has developed the necessary control. A child moving from a Revvi 16 or 16 Plus is stepping onto a larger bike with different performance and equipment.
If the Revvi 18 is too large, compare the smaller models in our Revvi range. If the riding position is already cramped, explore the Revvi 20.
Revvi 18 speed settings and battery
The Revvi 18 has three selectable speed settings: approximately 9.5mph, 13.5mph and 20mph. Begin with the lowest appropriate setting and increase performance only when the rider can consistently control the bike.
How long does the battery last?
The removable 36V 5Ah battery provides different ride times depending on the mode and conditions. The following figures are approximate estimates.
| Mode | Speed | Ride time |
|---|---|---|
| Slow | 9.5mph | 80 minutes |
| Medium | 13.5mph | 45 minutes |
| Fast | 20mph | 25 minutes |
Actual speed and runtime vary with rider weight, terrain, temperature, riding style and battery condition. The longest estimate should not be treated as the expected runtime in every mode.
Charging and spare batteries
Allow approximately 1 hour 50 minutes for charging, following the instructions supplied with the bike and battery. Use the correct charger and check model compatibility before purchasing a replacement battery.
For longer riding sessions, compare the spare-battery options within our Revvi 18 bikes and bundles . Read each listing to confirm exactly what is included.
Revvi 16 XL vs Revvi 18 vs Revvi 20
These models offer different combinations of physical size and equipment. Motor wattage alone does not tell you which bike fits the rider or how it will feel to ride.

| Model | Main specification | When to compare it |
|---|---|---|
| Revvi 16 XL | 16-inch wheels and a 24V 600W hub motor. | When the rider needs a smaller platform than the Revvi 18. |
| Revvi 18 | 18-inch wheels, a 36V 500W hub motor, full suspension and hydraulic brakes. | When a growing rider has outgrown a smaller bike and fits the 18-inch platform comfortably. |
| Revvi 20 | 20-inch wheels and a 36V 800W hub motor. | When the rider needs more physical room and can confidently handle the larger bike. |
Should you choose the Revvi 18 or 20?
Compare the riding position first. The Revvi 18 may suit a rider who finds the 20 too large, while the Revvi 20 is worth considering when the 18 feels cramped. Neither model is automatically the right choice based on age alone.
