The Ultimate Guide To The Revvi 20 Inch Balance Bike

Meet the Revvi 20

If you’re after a serious 20-inch electric balance bike that feels like a real off-road machine, the Revvi 20 is the one that changes the game. It’s built for bigger, bolder riders who need more power, more travel in the suspension, and brakes that can actually match their speed. Unlike toy-like starter bikes, this one has the size and weight to make your child feel like they’re stepping into proper motocross territory - without jumping too far, too fast.

I’ve had parents tell me that when their kids hop onto a Revvi 20 for the first time, they suddenly sit taller, throttle more carefully, and smile wider. It’s a bike that commands respect in the best way - it pushes riders to grow their skills while still being friendly enough to learn on. If your child has outgrown smaller Revvi balance bikes or is itching for bigger trails, the Revvi 20 is the upgrade that keeps the adventure alive.

Who Will Get the Most Out of the Revvi 20

The Revvi 20 isn’t for every child - it’s aimed squarely at riders with enough confidence and strength to handle a 22 kg bike. As a rule of thumb, I recommend an inside leg measurement of around 65 cm or more. Most kids hit that around ten years old, but some get there sooner.

It’s perfect for:

• Kids moving up from a Revvi 16 or 18 who feel limited by speed or suspension.
• Families who ride on forest tracks, grassy fields, or light off-road terrain.
• Riders who want a stepping stone before full-size motocross or e-mountain bikes.

For kids ready to push their riding, this model has the room and capability to grow with them.

On-Trail Performance and Everyday Feel

When you twist the throttle on the Revvi 20, the first thing you’ll notice is the smooth, confident acceleration. The 800 W motor isn’t jerky or intimidating; it delivers power steadily so kids can ease into speed. Low mode keeps things tame for practice, Medium is the sweet spot for most riding, and high gives that thrilling top speed of 22 mph on open ground.

Suspension is where the Revvi 20 really sets itself apart. The front hydraulic forks swallow bumps and small roots easily, while the rear air shock takes the sting out of rougher ground. For kids moving from a rigid or front-only setup, the difference is massive. They’ll feel more control over uneven terrain and less fatigue after longer rides.

Battery performance is equally impressive. In gentle use, you can get up to an hour and a half of riding on Low. Realistically, most kids will use Medium and see around an hour, still plenty for trail sessions or park runs. And with the removable battery, you can carry a spare or charge it indoors without lugging the bike inside.

Braking is reassuringly strong thanks to hydraulic discs front and rear. On wet or muddy trails, stopping power is predictable, which is a big confidence boost for parents. The aluminium frame gives the bike strength without excessive weight, and the knobbly tyres provide grip in loose soil or grass.

Why Bigger Kids Love This Bike

Older kids want a bike that doesn’t feel like a “little kid” model. The Revvi 20’s size, adjustable seat height, and powerful motor tick that box. It’s big enough to feel like a proper machine but not so massive that it’s unwieldy. The three speed modes mean there’s still a safety net while they’re learning: start slow, build skills, then unlock the fun.

Parents often tell me their kids ride the Revvi 20 for years because it grows with them. An adjustable handlebar and seat let you fine-tune the fit as they stretch out. And because it’s built tough, the bike can handle spills, muddy days, and long-term use without giving up. It’s a purchase that lasts beyond a single season of riding.

Side-by-Side with Other Revvi Models

This table shows how the Revvi 20 slots into the range: slightly faster and more powerful than the 18, with the extra comfort of rear suspension and hydraulic braking on both wheels.

Getting It Set Up and Keeping It Running Smoothly

Your Revvi 20 arrives mostly assembled. You’ll need to fit the front wheel, handlebars, foot pegs, and number board. Even if you’re not mechanically minded, the process is straightforward, just follow the video below. I recommend double-checking all bolts, brake levers, and tyre pressures before the first ride.

• For long-term care, give the bike a quick once-over before each session:
• Check tyre pressure and tread, especially after muddy outings.
• Test the brakes for firmness and response.
• Inspect the rear shock pressure and front fork for leaks.
• Tighten bolts on the swingarm, stem, and pedals.
• Keeping the bike clean after off-road use will extend its life. A gentle hose down (avoiding direct high-pressure water on bearings or electrics) and a dry-off will prevent rust or electrical issues.

The Revvi 20 has the same assembly as the Revvi 18, so watch this video below.

Looks That Match Its Performance

The Revvi 20 isn’t just about performance, it looks the part too. The frame is powder-coated in tough finishes designed to shrug off scratches. Bold graphics and motocross-inspired styling make it stand out on the trail or in the park. Older riders love that it doesn’t look “kiddy” but still has plenty of flair.

If your child wants to make their bike their own, Revvi offers seasonal decal packs and limited-edition colourways. Whether they’re after something stealthy or something that pops, there’s an option to match their personality.

Riding Responsibly: Safety and UK Rules to Know

Because the Revvi 20 is fast and powerful, it’s not road legal in the UK. It’s designed for private land, off-road tracks, or dedicated practice areas. Always check you have permission to ride on the land you’re using.

Safety gear is non-negotiable. A certified helmet, gloves, and knee and elbow pads are the bare minimum. Teach your child to check brakes and throttle before each ride and to keep within their limits, especially on new trails or wet conditions. A quick parent ride or slow test lap can highlight hazards before the kids go full speed.

Smart Buying Tips for Parents

When picking an electric balance bike, start by measuring your child’s inside leg and checking it against the seat height range. For the Revvi 20, 65 cm or more is ideal. Think about where you’ll ride: the Revvi 20’s suspension and power are perfect for rougher ground, but if you’re sticking to smooth paths, a smaller model might be enough.

Motor power matters: the 800 W hub on the Revvi 20 is a big step up, so make sure your child has throttle control experience. Hydraulic brakes are a plus for safety, but they do need occasional maintenance, something worth factoring in. And check that you have support for spares, Future Riders keeps parts on hand for quick fixes

Your Child’s First Outing on the Revvi 20

Start slow. Find a wide, flat, open area and set the bike to Low speed. Before powering up, have your child walk the bike, get a feel for the weight, and practise balancing. Then, with the throttle engaged, encourage gentle starts and stops.

Stay close at first - kids can surprise themselves with how quickly the Revvi 20 accelerates. Once they’re comfortable, move to Medium and gradually introduce uneven ground or small slopes. Remind them to stay seated over bumps and to use smooth throttle control. Building good habits early makes for safer, more confident riding later.

Keeping the Fun Going for Years

The Revvi 20 is designed to be serviceable and upgradeable. You can swap out the battery, fit new tyres for specific terrain, or refresh the brake pads in under ten minutes. Seasonal servicing of the suspension keeps it plush and responsive.

Because the frame and components are robust, the bike can easily be passed down to a younger sibling or friend once your child outgrows it. With a bit of care, cleaning, charging properly, and checking bolts - this bike will keep delivering thrills for seasons to come.

Final Thoughts on the Revvi 20

The Revvi 20 is, in my eyes, a brilliant choice for confident young riders who want something that feels like a true dirt bike without stepping up to full-size power. It’s tough, quick, and designed with real riders in mind: powerful brakes, real suspension, and a removable battery that keeps the fun rolling.

If your child is ready for bigger trails, more speed, and a bike that can grow with them, the Revvi 20 is the one I’d recommend every time. Watching kids master this machine and develop genuine riding skills is why I love what we do at Future Riders, it’s not just a purchase, it’s the start of many weekends of adventure.
