Frequently Asked Questions about our Revvi Bikes

Are Revvi bikes legal?

The short answer: they’re not road legal. These bikes are designed purely for off-road riding, so keep them off public roads, pavements, and cycle paths. The best option is private land, with the landowner’s permission, or a proper off-road riding track (why not check out our article on the best kids MX tracks in the UK for more information).
What’s the top speed of a Revvi electric balance bike?

Speed is where the fun comes in, but it’s also where control matters most. Each model has a different ceiling: Revvi 12" – up to 10 mph, Revvi 16" & 16" Plus – up to 12 mph, Revvi 18" – up to 20 mph, Revvi 20" – up to 22 mph. These numbers might not sound huge on paper, but when you’re a metre off the ground and on dirt, it’s plenty. The key is that all models offer lower settings, so beginners can start slow, get their balance right, and move up when ready.
Can I adjust the speed settings on a Revvi bike?

Yes, and it’s one of the best features for managing a young rider’s progress. Every Revvi has built-in speed modes, allowing you to limit the bike while your child’s still finding their footing. For example, the Revvi 12" starts at 5 mph and steps up to 10 mph. The larger bikes offer three modes, so you can start low, move to medium, and finally let them stretch to full speed. It’s the safest way to build skills without taking the thrill out of riding.
How do you charge a Revvi bike?

Charging is simple but worth doing right. Each bike comes with its own charger. All you have to do is plug it into a normal household socket, connect it to the bike’s charging port, and let it run until full. There’s no need for complicated setups or extra gear. Follow the manual’s guidance, and don’t cut the charging short as this helps keep the battery healthy and ensures your rider gets maximum time out on the track. Another great aspect of Revvi batteries are that they can be removed and charged, which is ideal for long days racing and cold storage.
How long does a Revvi bike take to charge?

Here’s what you can expect: Revvi 12" – around 2.5–3 hours, Revvi 16" & 16" Plus – around 5.5–6 hours, Revvi 18" – around 2 hours, Revvi 20" – around 2–3 hours. If you’re used to charging adult e-bikes, you’ll notice the smaller models fill up much faster. The bigger ones take longer but also deliver more power and speed. The trick? Put it on charge as soon as the ride’s over, and it’ll be ready for the next session or buy a spare Revvi bike battery so you can always have one ready to swap straight over.
How do I know which size Revvi bike to choose?

Picking the right size is about matching the bike to the rider’s age, build, and experience: Revvi 12" – Ages 2–6, ultra-light, ideal for complete beginners. Revvi 16" & 16" Plus – Ages 5+, for riders ready for more control and speed. Revvi 18" – Ages 8+, heavier and more powerful, for confident riders. Revvi 20" – Ages 10+, the closest thing to a mini dirt bike. If you’re unsure, measure their height and compare it to the bike’s seat height. Or better yet, get in touch. We’ve helped plenty of parents find the perfect fit without guessing.
