My Take as a British MX Rider
Age is a useful starting point, but confidence and control matter just as much.
The right Revvi bike should help the rider build skill, not overwhelm them. A bike that is too big or too powerful can slow their progress down.
If your child is between sizes, only size up if they can safely control the bigger bike.

Revvi 16 – Best Starter 16” Bike
The Revvi 16 is the natural next step from the Revvi 12 and suits young riders who are ready for a bigger 16” platform.

- Ideal for younger progression riders
For more confident younger riders, the Revvi 16 Plus adds extra capability while keeping a manageable 16” size.
Best Revvi Bike for Ages 6–9
Revvi 16 XL
Best for: riders who need more than a Revvi 16 Plus but may not be ready for an 18”.
- Strong bridge before Revvi 18
- More powerful 16” platform
- Good for confident riders aged around 6–9
Revvi 18
Best for: taller or more confident riders who are ready for a bigger platform.

- More room and stability
- Great long-term progression bike
The Revvi 16 XL is a great middle ground if your child is not quite ready for an 18, but needs more bike than a standard 16 or 16 Plus.
If your child is taller or already confident, the Revvi 18 may be the better long-term choice.
Best Revvi Bike for Ages 8–12
Older or more confident riders will usually benefit from the Revvi 18 or Revvi 20.
Revvi 18: best all-round fit for most 8–11 year olds.
Revvi 20: better for taller, older or more confident riders.
Revvi 18: more manageable and confidence-building.

The Revvi 20 is the top Revvi choice for older, taller or more confident riders.
- Largest Revvi model

The Revvi 20 is the best Revvi option for riders who have outgrown smaller models and need more size, stability and long-term headroom.
Shop Revvi 20How to Choose the Right Revvi Bike
Height
A taller rider may suit the next size up earlier than the age guide suggests.
Confidence
A nervous rider is usually better on a smaller, easier bike first.
Experience
Riders with balance bike, BMX or MX experience may progress faster.
Progression
The best bike should suit them now and still leave room to improve.
If your child is between sizes, we usually recommend sizing up for longer use — as long as they can safely control the bike.

For first-time riders: Revvi 12
