Revvi has just announced its two biggest bikes ever, and both are available to order right now at Go Off Road Barnsley. The new Revvi 24" is the first Revvi built to carry riders into their teens, with 1500W of peak power and a 30mph top mode. The Revvi 20" Plus takes the best-selling 20" platform and upgrades it with the same 48V motor, proper adjustable suspension and hydraulic brakes. Finance is available on both with an instant decision.
Here are the full specs, how the new models stack up against the current Revvi 20", and which one fits your rider.
Revvi 24": the first Revvi built for teens
Until now the Revvi range topped out at the 20", aimed at riders around 10 years old. The 24" changes that. It keeps everything parents choose Revvi for: twist-and-go simplicity, selectable speed modes, no gears, no clutch. Then it scales all of it up for taller, heavier riders who have outgrown their current bike but are not ready for a full-size electric dirt bike.
The headline numbers are serious:
- 48V 1000W brushless hub motor with 1500W peak power and 132 Nm of torque
- 48V 15Ah battery with up to 35km of range
- Three speed modes (15.5, 22 and 30mph) so the bike grows with the rider
- RST suspension front and rear with compression and rebound adjustment
- 4-piston hydraulic disc brakes front and rear
- Adjustable seat height that keeps pace as your rider shoots up
- 30.8kg, light enough for a teenager to pick up and manage off-road
- Available in black at £1,599
Revvi 20" Plus: the 20" with real bite
The standard Revvi 20" is one of the most searched-for kids’ electric bikes in the UK, and the Revvi 20" Plus answers its most common criticism: riders get quick, then want more. Here is what the Plus adds:
- Same 48V 1000W motor as the 24", peaking at 1500W with 132 Nm of torque
- Three speed modes topping out at 27mph, up from 22mph on the standard 20"
- EXHO air shock up front, Fastace spring shock at the rear, both with compression and rebound adjustment, spec you normally see on much bigger bikes
- Aluminium frame with forged swing arm and linkage
- Hydraulic disc brakes front and rear on aggressive 20" knobbly tyres with spoked rims
- 75kg max rider weight, so it will not be outgrown in a season
- 28kg all in, £1,399, in stock now

Which Revvi Size Should You Choose?
Forget age ranges for a second. The single best way to size any of these bikes is your child’s inside leg measurement. Stand them against a wall in their shoes, slide a book up between their legs until it stops, and measure from the top of the book to the floor. On the right bike, they can sit on the seat with both feet flat on the ground and knees slightly bent. If they are on tiptoes, leaning the bike over to get a foot down, or stretching their arms to reach the bars, the bike is too big, no matter what the age label says.
Revvi 20": the sensible starting point (around 130cm and up)
The seat adjusts from roughly 68.5cm to 87.5cm, which suits most riders from about 130cm tall, typically ages 8 to 12. If this is your child’s first powered bike, start here. The 22mph top mode sounds tame next to the new bikes but it is plenty for gardens, fields and first track days, and at 22.5kg it is light enough for most kids to pick up themselves when it goes over. That last bit matters more than parents expect: a child who cannot lift their own bike stops riding it.
Revvi 20" Plus: same size, serious step up in pace
The Revvi 20 " Plus bike fits the same height range as the standard 20", so the choice between them is not about size at all. It is about experience and appetite. The extra 5.5kg of bike, the stronger acceleration and the 27mph ceiling all reward a rider who already brakes, corners and picks lines confidently. If your child has spent a season or two on an 18" or a standard 20" and is visibly riding within its limits, the Plus gives them somewhere to go. If they are still building basics, the extra power gets in the way rather than helping.
Revvi 24": for genuine teens, not tall 10-year-olds
The Revvi 24" needs an inside leg of at least 77cm, with the seat adjusting all the way to 101cm, so it will carry a rider through their entire teens. That huge range is the point: it is the last Revvi they will ever need. But be honest about readiness. 30mph is proper dirt bike speed, so treat it like one: full gear, open private space, and a rider who has already proven themselves on a smaller bike. If your 10-year-old is tall for their age, resist the temptation to size up to “grow into it”. A bike they can barely touch down on at 30mph is not a growth plan.
Still torn between two sizes? The honest answer is to come and sit on them. We are at our Wakefield showroom with the full range on the floor, and a two-minute sit tells you more than any chart. Bring the kids.

The Revvi 24" launched in 2026, with the first UK bikes delivered over the summer. Stock moves quickly, so check the Revvi 24" product page for live availability.
What is the difference between the Revvi 20" and the Revvi 20" Plus?
The 20" Plus has a 48V 1000W motor (1500W peak) instead of the 36V 800W motor on the standard Revvi 20". It tops out at 27mph instead of 22mph and adds compression and rebound adjustable suspension front and rear. It weighs 28kg against 22.5kg and costs £1,399 against £1,099. Both fit the same rider height, so the choice is about experience, not size.
Should I buy the Revvi 20" Plus or the Revvi 24"?
Choose by size, not power. Both bikes share the same 48V motor and 15Ah battery. The Revvi 24" needs an inside leg of at least 77cm. If your rider is below that, the Revvi 20" Plus is the right bike.
How fast are the Revvi 24" and Revvi 20" Plus?
The Revvi 24" has three speed modes: 15.5, 22 and 30mph. The Revvi 20" Plus has three modes: 13.6, 20 and 27mph. Parents can start a rider on the lowest mode and move up as their skill builds.
What age is the Revvi 24" for?
Revvi rates the 24" for riders aged 12 and over, and the 20" Plus for riders aged 10 and over. Inside leg, weight and confidence matter more than age, so measure your rider before you choose.
What is the weight limit on the Revvi 24" and 20" Plus?
Both bikes have a maximum rider weight of 75kg.
How long does the battery last, and how long does it take to charge?
Both bikes run a 48V 15Ah battery. Expect around 1 hour 20 minutes of constant riding in the low speed mode, 50 minutes in medium and 30 minutes in high. A full charge takes around 5 hours.
Is there a Revvi 22" or a Revvi 26"?
No. The Revvi range runs 12", 16", 16" Plus, 16" XL, 18", 20", 20" Plus and 24". The 24" is the biggest bike Revvi makes.
Can I buy a Revvi 24" or 20" Plus on finance?
Yes. Finance is available on any purchase over £300 with an instant decision. Credit is subject to age, status and affordability.
Can I get a graphics kit for the Revvi 24"?
Yes. We stock Revvi 24" graphics kits in a range of colours and styles, covering the number board, front forks and swing arm. Fitting is available in our workshop.
What warranty do the bikes come with, and how are they delivered?
Both bikes include a 6 month warranty. We deliver nationwide, or you can collect from our Wakefield showroom. Bikes can be supplied boxed or fully built and PDI checked.
Are Revvi bikes road legal in the UK?
No. Revvi bikes have no pedals and exceed the legal limits for an electric bike, so they cannot be ridden on roads, pavements or public land at any age. They are for private land with the landowner's permission.
