2026 REVVI SIZE GUIDE
Best Revvi Bike by Age
Compare the Revvi 12, 16, 16 Plus, 16 XL, 18, 20 and 24 to find the right electric bike for your child's age, height, confidence and riding experience.
The best Revvi bike is the one your child can confidently control now—not simply the biggest model within their age range.
Revvi offers one of the clearest progression routes in the UK kids' electric bike market, beginning with the Revvi 12 for very young first-time riders and progressing through to the larger Revvi 24 for taller teenagers.
Choosing the best Revvi bike for your child comes down to age, height, confidence and riding experience.
The Revvi range now covers everything from a child's first lightweight electric balance bike through to larger and considerably more capable youth electric bikes for older riders.
That wide choice is one of Revvi's biggest strengths, but it can also make choosing between closely positioned models such as the Revvi 16, 16 Plus and 16 XL more difficult.
This guide explains where every current Revvi model sits within the range and which type of rider each bike is best suited to.
Quick Answer
Which Revvi Bike Should You Choose?
Revvi 12 is the best starting point for very young first-time riders, while the Revvi 16 introduces a larger platform for children ready to progress.
The Revvi 16 Plus and Revvi 16 XL suit increasingly confident riders who still benefit from a manageable 16-inch-style platform.
The Revvi 18 is one of the best all-round step-up bikes in the range, while the Revvi 20 suits older and taller riders who need more room.
The Revvi 24 is the largest and most capable current Revvi, designed for taller teenagers and experienced riders who have outgrown the smaller models.

Why Revvi?
A Clear Electric Bike Progression Route
Revvi has become one of the UK's most popular kids' electric bike ranges because the models follow a clear progression in size, performance and rider ability.
A child can begin on the Revvi 12, move through the different 16-inch options and continue onto the Revvi 18, 20 and 24 as their height, strength and riding confidence increase.
That makes Revvi particularly useful for families who want a recognisable upgrade route rather than moving between unrelated brands and platforms.

A Range Designed Around Progression
Model-by-Model Guide
Which Revvi Is Best for Each Rider?
Each Revvi occupies a slightly different position within the range. The best choice depends on how comfortably the rider can control the bike today, rather than simply choosing the largest model they could potentially grow into.
Ages 2–4 · Best First Revvi
Revvi 12
The Revvi 12 is the natural starting point for very young riders learning balance, throttle control and basic braking.
Its compact size makes it much easier for a small child to place their feet down, steer confidently and recover from minor mistakes.
Best for: young beginners who need the smallest and most manageable Revvi platform.
- First electric balance bike
- Small and lightweight platform
- Simple introduction to throttle control
- Best suited to younger beginners
Choose the Revvi 12 When
The Rider Is Starting From Scratch
For a nervous, smaller or completely inexperienced rider, the Revvi 12 will normally build more confidence than buying a larger bike too early.
Ages 4–6 · Starter 16-Inch Revvi
Revvi 16
The Revvi 16 is designed for children who are ready to move beyond the smallest balance bike platform but still need a straightforward and manageable machine.
It is the simpler starter option within the Revvi 16-inch range and suits younger riders who are beginning to develop confidence.
- Starter 16-inch electric bike
- Natural step up from the Revvi 12
- Suited to beginners and progressing riders
- More room without immediately adding too much bike
Our View
The Sensible First 16-Inch Choice
Choose the standard Revvi 16 when the rider needs a bigger bike than the Revvi 12 but is not yet ready for the additional capability of the Plus or XL models.
Choose the Plus When
The Rider Already Has Confidence
The Revvi 16 Plus makes the most sense when a child still fits a 16-inch bike but is ready for a more capable progression platform than the standard Revvi 16.
Ages 5–8 · More Capable 16-Inch Bike
Revvi 16 Plus
The Revvi 16 Plus sits above the standard Revvi 16 and is intended for riders who want a stronger progression bike while retaining a manageable frame size.
It is better suited to confident younger children than complete first-time riders.
- More capable than the standard Revvi 16
- Suited to confident younger riders
- Useful middle step within the range
- Retains a manageable 16-inch format
Ages 6–9 · Best Bridge to Revvi 18
Revvi 16 XL
The Revvi 16 XL occupies an important position between the smaller Revvi models and the larger Revvi 18.
It is a strong option for a child who needs more room and capability but may not yet be physically ready for the jump to an 18-inch platform.
- Larger progression-focused 16-inch model
- Best bridge before the Revvi 18
- Suited to confident riders
- More substantial without moving immediately to 18 inches
Our View
The Missing Step Many Riders Need
For riders who have outgrown smaller 16-inch bikes but would find the Revvi 18 too large, the 16 XL can be the most sensible choice.
Ages 8–12 · Best All-Round Step-Up
Revvi 18
The Revvi 18 is one of the strongest all-round progression choices in the range and suits older children who have developed genuine bike control.
It offers a larger riding platform than the 16-inch models without moving immediately to the considerably bigger Revvi 20 or Revvi 24.
Best for: confident riders who have physically outgrown the smaller Revvi models.
- Strong all-round progression option
- More room for older riders
- Natural next step after the Revvi 16 XL
- Suited to confident and developing riders
Our View
The Range's All-Round Sweet Spot
For many older children, the Revvi 18 provides the best balance between manageable size, meaningful progression and room to improve.
Choose the Revvi 20 When
The Rider Needs More Physical Room
The Revvi 20 is best considered when the rider is genuinely too tall or cramped on the Revvi 18 rather than simply because they fall within an overlapping age range.
Ages 10–14+ · Larger Progression Platform
Revvi 20
The Revvi 20 is designed for older, taller and more confident riders who need a larger platform than the Revvi 18 can provide.
It remains a strong choice for many young teenagers and sits below the flagship Revvi 24 within the range.
- Larger frame and riding position
- Suited to older or taller riders
- Natural progression from the Revvi 18
- More manageable than immediately moving to the Revvi 24
Ages 12–16+ · Flagship Revvi
Revvi 24
The Revvi 24 is the largest and most capable current model in the range, intended for taller teenagers and experienced riders who have outgrown the Revvi 20.
Its larger 24-inch platform gives growing riders more room without requiring an immediate move to a full-size adult electric dirt bike.
- Largest Revvi platform currently available
- Designed for taller teenagers
- Natural progression after the Revvi 20
- Best suited to experienced riders
Our View
A Proper Option for Riders Who Have Outgrown the Range
The Revvi 24 is not simply the automatic choice for every older child. It makes the most sense when a rider has the height, strength and experience to control the largest bike confidently.
Buying Advice
How to Choose the Right Revvi Bike
Age is useful for narrowing down the range, but the final decision should also account for the rider's physical size, confidence and previous experience.
1. Height
Can They Reach Comfortably?
A taller child may fit the next size earlier, while a smaller rider may benefit from remaining on the lower model for longer.
2. Confidence
Do They Feel in Control?
A nervous rider will usually progress faster on a smaller, easier bike than on a larger machine that feels intimidating.
3. Experience
What Have They Ridden Before?
Previous balance bike, BMX, bicycle, electric bike or motocross experience can affect how quickly a rider is ready to progress.
4. Progression
Is There Room to Improve?
The ideal model should fit the rider properly now while still giving them enough capability to build skill and confidence.
Should You Size Up?
Sizing up can work when a child is between models, but only when they can safely control the larger bike.
Do not size up purely to achieve longer ownership. A bike that is too tall, heavy or powerful can reduce confidence and slow rider progression.
Common Decisions
Which Closely Matched Revvi Should You Choose?
These are the comparisons most likely to cause uncertainty when moving through the range.
Revvi 16 vs Revvi 16 Plus
Choose the Revvi 16 for a simpler starter bike. Choose the Revvi 16 Plus for a more confident rider who is ready for a more capable progression model.
Revvi 16 XL vs Revvi 18
Choose the 16 XL when the rider still benefits from a smaller platform. Choose the Revvi 18 when they are taller, older and ready for a physically larger bike.
Revvi 18 vs Revvi 20
The Revvi 18 is the stronger all-round step-up for many riders. The Revvi 20 is better when they need more room and can confidently manage the larger platform.
Revvi 20 vs Revvi 24
Choose the Revvi 20 for many older progressing riders. Choose the Revvi 24 for taller teenagers who have physically outgrown the Revvi 20.
Complete Rider Setup
Most Customers Choose a Revvi Bundle
Many families choose a Revvi bundle so the rider has the correct equipment and setup from day one rather than adding everything separately later.
Bundles can provide better overall value while making the buying process simpler.
Shop Revvi BundlesRider Experience
My Take as a British Motocross Rider
Age is a useful starting point, but confidence and control matter just as much when choosing a Revvi.
The right bike should help the rider build skill rather than overwhelm them. A model that is too tall, heavy or powerful can make basic control more difficult and slow their progression.
When a child is between sizes, I would only move them onto the larger bike if they can confidently reach the ground, steer it, stop it and recover it when things do not go perfectly.
For taller teenagers who have genuinely outgrown the Revvi 20, the Revvi 24 gives them a larger platform without immediately moving onto a full-size adult electric dirt bike.
