Best Kids' Electric Bikes in the UK

A kids’ electric bike is one of the best ways to get a child hooked on two wheels. It is also the most misunderstood corner of the e-bike market. Almost everything sold as a “kids’ electric bike” in the UK is actually a throttle-controlled electric balance bike or a mini electric motorbike. That matters. These machines are not the pedal-assist EAPCs adults ride to work. They are powered on demand. They have no pedals or only a token set. In law they are for private land and off-road use only.

We have ranked the models below on the things that keep children safe and keep them riding: an adjustable parental speed limiter, a low standover height so small feet reach the floor, a weight a child can pick up after a tumble, and proper UK support if something breaks. Prices shift often. Use the check-price links for the live figure.

How we chose

We focused on bikes genuinely sold and supported in the UK. We then scored each on five factors: the parental speed limiter and how it stages up, standover height and fit, weight relative to the target age, brakes and build quality, and value against rivals. We do not take payment from manufacturers. Rankings never move for an affiliate commission. We say “around” rather than invent a number where a spec could not be confirmed from the maker.

+ What we like

• Three-stage parental speed limiter grows with confidence
• Light enough for a child to lift after a fall
• Huge UK spares and support network

• Throttle only, so it is private-land use, not road legal

Our verdict: The default kids' electric bike for good reason: a sensible speed limiter, a manageable weight and the best support in the UK.

Check price

The Revvi 16 is the bike most UK families end up with. It earns the top spot for good reason. Its standout feature is the three-stage speed limiter. This lets you cap the bike at roughly 8, 10 or 12mph and raise it only as your child’s confidence grows. The Revvi 16 weighs around 14kg. That is light enough for a young rider to pick up after a spill. The removable 24V battery also makes charging easy. Revvi’s UK spares network means a worn part is rarely the end of the bike. The only thing to keep front of mind is it is throttle-driven. It stays on private land as a result.

2. Revvi 12 - best first electric bike (age 3 plus)

Revvi 12

★★★★★ ★★★★★ 4.5 around £325

Best for: Best first electric bike (age 3 plus)

Motor

100W hub (throttle)

Battery

24V

Range

Up to around 1 hour run time

Weight

Around 11kg

+ What we like

• Gentle 100W motor ideal for first-timers
• Low seat lets small children sit flat-footed
• Best value entry into the category

- Watch-outs

• Outgrown quickly by confident riders

Our verdict: The gentlest, cheapest way into electric riding for a three or four year old, with a soft 100W motor and a low, reassuring seat.

Check price

The Revvi 12 is the ideal first step for a child just moving on from a push-along balance bike. The gentle 100W motor will not overwhelm a nervous three or four year old. The low seat height means they can sit flat-footed and feel in control. At around 11kg it is the lightest bike here. The trade-off is fast learners outgrow it within a year or two. It is still hard to beat as a confidence-builder and a relatively low-cost entry point though. Many families buy the 12 first and step up to the 16 later.

3. STACYC 16eDRIVE - best premium build for ages 4 to 7

#3

STACYC

STACYC 16eDRIVE

★★★★★ ★★★★★ 4.4 around £999

Best for: Best premium build for ages 4 to 7

Motor

Brushless hub (throttle)

Battery

20V removable lithium

Range

Around 30 to 60 min per pack

Weight

Around 8kg

+ What we like

• Very light alloy frame, easy for a child to handle
• Swappable batteries extend ride time
• Excellent build and resale value

- Watch-outs

• Expensive for what is a balance bike
• No pedals, so pure throttle skills only

Our verdict: The original powered balance bike, beautifully made and feather light, but you pay a clear premium for the name and quality.

Check price

STACYC invented this category. The 16eDRIVE shows why the brand still commands a premium. The alloy frame keeps weight to around 8kg. That is genuinely light for a powered bike. It makes the bike easy for a small child to handle and to right after a fall. Two speed modes keep early rides gentle. Swappable lithium packs mean you can keep a fresh battery ready so the fun does not stop. The catch is simply price: at around £999 it costs more than twice the Revvi 12 and remains a pedal-free balance bike. It is worth it for families who want the best build and strong resale though.

4. Revvi 20 - best for older, confident kids

#4

Revvi

Revvi 20

★★★★★ ★★★★★ 4.3 around £700

Best for: Best for older, confident kids

Motor

36V 800W hub (throttle)

Battery

36V removable

Range

Varies by mode and terrain

Weight

Around 23kg

+ What we like

• Staged speed unlock from 10 to 22mph
• Proper suspension and disc brakes
• Handles rougher off-road trails

- Watch-outs

• 22mph top speed needs supervision and protective kit
• Heavy for younger riders to manage

Our verdict: A serious step up for confident older children, with real suspension and a staged unlock to 22mph, but it demands supervision and kit.

Check price

The Revvi 20 gives a child somewhere to grow once they have mastered a smaller bike. The 36V 800W motor stages up through 10, 16 and finally 22mph as they earn it. The suspension and disc brakes mean it copes with proper off-road trails rather than just a flat garden. It weighs around 23kg. That suits older, stronger kids better. The top speed firmly puts this into supervised, protective-kit-on territory too. Treat it as the mini electric motorbike it really is and it is brilliant fun. Underestimate it and it becomes too much bike.

5. Revvi 24 - best for teens off-road

Revvi

Revvi 24

★★★★★ ★★★★★ 4.2 around £950

Best for: Best for teens off-road

Motor

48V 1000W hub, 1500W peak (throttle)

Battery

48V removable

Range

Varies by mode and terrain

Weight

Around 28kg

+ What we like

• Strong 1500W peak motor for hills and trails
• Full-size 24 inch wheels for older kids
• Removable battery for indoor charging

- Watch-outs

• Powerful and heavy, strictly supervised private-land use
• Not road legal as an EAPC

Our verdict: The most powerful kids' bike here, built for teenagers tackling real trails, but very much a private-land machine that needs respect.

Check price

The Revvi 24 is effectively a junior electric motorbike. A 48V motor producing up to 1500W peak and full-size 24 inch wheels give it the power and reach for an older teenager to ride proper off-road terrain. The removable battery charges indoors and the build is robust. None of that changes the legal picture: at this power it is nowhere near an EAPC. It is strictly for private land or licensed off-road tracks with permission. Pair it with a full-face helmet and supervision and a sporty teenager will love it.

How to choose a kids’ electric bike

Start with fit, not power. Sit your child on the bike and make sure they can put both feet flat on the floor. A low standover height is the single biggest safety factor at this age. Check the speed limiter next: every bike here has one. A staged limiter like Revvi’s lets you keep early rides slow and allow more speed as skills build. Weight matters too. A child who cannot lift their own bike after a fall quickly loses confidence.

Budget for safety kit on top of the bike. Do not treat it as an afterthought. A correctly fitted helmet is non-negotiable. A full-face helmet, gloves, knee pads and elbow pads become sensible rather than optional once you move up to the faster Revvi 20 or 24. Choose somewhere safe to ride too: a private garden, a friend’s field with permission, or a licensed off-road track. Pavements, parks, cycle paths and bridleways are public. A throttle bike does not belong on any of them.

Think about how long the bike will last as well. Younger children grow quickly. Many families find the most economical path is to start small with the Revvi 12. They then step up to the 16 once confidence and leg length allow. A removable battery is worth paying for. It lets you charge indoors, keep a spare ready, and replace the pack years later rather than scrapping the whole bike. Check that spares such as tyres, chargers and controllers are stocked in the UK before you commit. An orphaned import can otherwise become unusable the moment one part fails.

Be clear-eyed about the law too. These are throttle machines for private land. They are not pedal-assist commuters. A teenager who wants to ride to school on the road needs a true 250W pedal-assist EAPC limited to 15.5mph and a rider aged 14 or over.
