2026 REVVI SIZE GUIDE
Best Revvi Bike by Age
Compare every current Revvi model — from the Revvi 12 through to the Revvi 20 Plus and Revvi 24 — to find the right bike for your child's age, height, confidence and experience.
Choose the bike your child can confidently control now, not simply the biggest model within their age range.
Choosing the best Revvi bike starts with age, but height, confidence and previous riding experience are equally important.
The current Revvi range provides a clear progression from lightweight electric balance bikes for young beginners to larger, faster youth electric bikes for experienced teenage riders.
Use the recommendations below as a practical starting point. Where age ranges overlap, choose the model that gives the rider comfortable control and a sensible amount of room to progress.
Quick Answer
Which Revvi Bike Should You Choose?
- Revvi 12: young beginners and first-time riders, approximately ages 2–6.
- Revvi 16 and 16 Plus: children progressing onto a larger and more capable 16-inch platform, approximately ages 5–8.
- Revvi 16 XL: riders who need more room than the smaller 16-inch bikes without moving straight to an 18, approximately ages 6–9.
- Revvi 18: a strong all-round step-up bike, approximately ages 8–12.
- Revvi 20: a larger 20-inch platform for older riders, approximately ages 10–14.
- Revvi 20 Plus: a more powerful 48V 1000W option for taller or experienced riders, approximately ages 10–14+.
- Revvi 24: the largest current Revvi for taller teenagers and experienced riders, generally ages 12+.
Exact-Age Recommendations
What Size Revvi for Each Age?
Children of the same age can differ significantly in size and ability, so use these answers alongside the rider's height and experience.
What size Revvi for a 4-year-old?
The Revvi 12 is normally the best choice for a four-year-old beginner. A particularly tall or experienced rider may be ready to consider the Revvi 16.
What size Revvi for a 6-year-old?
The Revvi 16 Plus is our main all-round recommendation for most six-year-olds. The standard Revvi 16 remains the calmer choice for a cautious beginner, while the roomier 16 XL may suit a taller rider.
What size Revvi for an 8-year-old?
A smaller or newer eight-year-old may still suit the Revvi 16 Plus. Choose the Revvi 16 XL when extra room is needed while retaining a compact platform, or the Revvi 18 as the best all-round step for a correctly sized rider from around age eight.
What size Revvi for a 10-year-old?
For most 10-year-olds, choose between the Revvi 18 and Revvi 20. The Revvi 18 suits smaller or newer riders; the Revvi 20 offers more room for taller children. The Revvi 20 Plus is the performance choice for confident riders.
What size Revvi for a 12-year-old?
A smaller or newer 12-year-old may still suit the Revvi 18. The Revvi 20 is the manageable larger option, the Revvi 20 Plus is the advanced 20-inch all-rounder, and the Revvi 24 is for riders who genuinely need the largest chassis.
What size Revvi for a teenager?
A smaller or less experienced teenager may still suit the standard Revvi 20. The Revvi 20 Plus is the stronger compact 20-inch option, while the Revvi 24 provides the most room for taller riders.

Model-by-Model Guide
How the Revvi Range Progresses
Each step adds physical size, performance or both. The right upgrade depends on what the rider can safely and confidently control.
First bike
Revvi 12
Best for young beginners who need a light and manageable introduction to electric riding.
Starter 16-inch
Revvi 16
A straightforward step up for children ready for a bigger chassis without excessive performance.
More performance
Revvi 16 Plus
Our best all-round 16-inch recommendation for many riders aged 5–8, combining manageable handling with useful performance and progression potential.
Roomier bridge
Revvi 16 XL
Ideal when a standard 16 feels small but the rider is not yet ready for the physical jump to an 18.
Shop Revvi 16 XLAll-round step-up
Revvi 18
One of the strongest all-round choices for children progressing beyond the 16-inch range.
Shop Revvi 18Larger platform
Revvi 20
Best for older and taller riders who need more room while maintaining manageable performance.
Shop Revvi 2048V performance
Revvi 20 Plus
The best advanced 20-inch all-rounder, with a 48V 1000W system, 48V 15Ah removable battery and upgraded suspension for confident riders.
Largest Revvi
Revvi 24
The largest Revvi platform for taller youth riders and teenagers who genuinely need the extra physical room. It is not automatically a better choice than the more compact 20 Plus.

Revvi 18 vs 20 vs 20 Plus vs 24
Choose the Revvi 18 for a smaller or less experienced rider who still needs a manageable step-up bike.
Choose the Revvi 20 when the rider needs a larger chassis but does not require the strongest performance package.
Choose the Revvi 20 Plus as the best advanced all-rounder for a confident rider who wants a powerful 48V 1000W system on a compact 20-inch platform.
Choose the Revvi 24 only when the rider is tall and experienced enough to benefit from the largest chassis in the range.
Beyond the Age Guide
Four Things to Check Before Choosing
1. Height
Can they comfortably reach?
The rider should be able to mount, stop and balance the bike without struggling against its size.
2. Experience
What have they ridden?
Experience on bicycles, balance bikes or smaller electric bikes may justify progressing sooner.
3. Confidence
Are they genuinely in control?
A nervous rider normally develops faster on a manageable bike than on an oversized, intimidating model.
4. Performance
How much power is appropriate?
The 20 Plus and 24 offer serious performance and should be chosen for ability, not age alone.

Frequently Asked Questions
Revvi Bike Age and Size FAQs
Can I choose a Revvi using age alone?
Age is a useful starting point, but height, confidence, strength and previous experience should determine the final choice.
Which Revvi is best for a 10-year-old?
Most 10-year-olds will suit the Revvi 18 or Revvi 20. The Revvi 20 Plus may suit a taller and more experienced rider who wants stronger performance.
Which Revvi is best for an 8-year-old?
A smaller or newer rider may still suit the Revvi 16 Plus. The Revvi 16 XL provides an in-between size, while the Revvi 18 is the best all-round step from around age eight when the rider fits it correctly.
What is the difference between the Revvi 20 and 20 Plus?
The Revvi 20 Plus steps up to a 48V 1000W system, a larger 48V 15Ah battery and upgraded suspension. The standard Revvi 20 is the more manageable option for riders who do not need that additional performance.
Is the Revvi 24 automatically best for an older child?
No. The Revvi 24 is physically the largest model and suits taller, experienced riders. A Revvi 20 or 20 Plus may offer a better fit for a smaller teenager.
Revvi 20 Plus or Revvi 24 for a teenager?
Choose the Revvi 20 Plus when the rider wants advanced performance but is better suited to a compact 20-inch chassis. Choose the Revvi 24 when a taller rider genuinely needs the larger riding position.
Should I buy a bike for my child to grow into?
Some room to progress is sensible, but the bike should still be controllable now. An oversized bike can reduce confidence and make stopping or balancing more difficult.
