Electric bike for a 10 year old: 6 models checked for fit

The best electric bike for a 10 year old has 24 inch wheels, pedal assist and a weight under 13 kg (29 lb). Of six kids’ e-bikes we checked, only the woom EXPLORE e 5 meets all three.

This page is for parents of 9 to 11 year olds. Every spec is the maker’s own, checked November 12, 2026, except the Cube, whose figures come from retailers because cube.eu would not load. We have not ridden these bikes. Younger children and electric balance bikes are covered in our main guide to electric bikes for kids.

What size e-bike does a 10 year old need?

A typical 10 year old needs a 24 inch e-bike. The CDC’s median 10 year old stands 138.8 cm (boys) and 138.2 cm (girls), about 4 ft 6 in.

Height ranges overlap, so pick the smaller bike when your child sits in both. A 10 year old at 141 cm fits the EXPLORE e 5 and e 6, and the smaller bike is 0.5 kg lighter and lower at the saddle, so both feet reach the ground at a stop. Measure inseam too, and run it through our bike frame size calculator.

How heavy should an e-bike for a 10 year old be?

Under 13.0 kg (28.7 lb). woom’s guidance is that a bike should weigh “no more than around 35% to 40% of a child’s body weight,” and 40% of a median 10 year old’s 32.58 kg is 13.0 kg.

The share is the bike’s weight over the child’s: 12.7 / 32.58 = 39%. We averaged the CDC’s boys (32.09 kg) and girls (33.06 kg) at age 10. Razor’s page prints the MD1 as “9 lb (19.5 kg)”; 19.5 kg is 43 lb, and that is the figure we used.

The weight gap comes from the battery. The two Bosch bikes carry 400 Wh, more than twice the woom’s 171 Wh, and a bigger pack means a heavier bike. A 10 year old rarely rides far enough to need it: woom claims “up to 50 km” for the EXPLORE e, which is longer than most children ride in a day.

Which e-bike should a 10 year old get?

The woom EXPLORE e 5 for most 10 year olds. It is the only bike here under 40% of a typical 10 year old, it fits the median height, and it assists only while the child pedals, up to 25 km/h (15.5 mph).

• If your child weighs under 31.8 kg (70 lb), even the EXPLORE e 5 is over 40%. Wait, or stay on a pedal bike for a year.
• If your child is over 145 cm (4 ft 9 in), go to the EXPLORE e 6 at 13.2 kg. It is sized to 165 cm.
• If your child rides mountain bike trails with a parent and weighs at least 41.5 kg (91 lb), the Commencal Meta HT 24 Power and its 60 Nm Bosch motor become reasonable.
• If the budget is under $500, the Razor Rambler MD1 at $499.99 is the cheapest pedal-assist option, but at 43 lb it suits a heavier 10 year old, and Razor caps the rider at 120 lb (54 kg).

The STACYC 20eDRIVE is a different machine: no pedals, a twist throttle and modes of about 10, 15 and 20 mph (16, 24 and 32 km/h). It is a trail and pump track toy, not a bike for the road. Its 20 mph top mode is as fast as a US Class 1 e-bike’s assist limit.

Price is the other gap. woom lists the EXPLORE e 5 at €1,849 on its Belgian site, on sale at €1,664, and £1,749 in the UK, and it shows no US listing. The older woom UP, still mentioned in many guides, “is no longer in production,” according to woom’s US page. Commencal listed the Meta HT 24 Power at $4,200 and “currently unavailable for purchase.”

Where can a 10 year old ride an e-bike?

In most US states, a 10 year old may ride a Class 1 or 2 e-bike, because federal law sets no age. New York, New Jersey and Great Britain are the big exceptions.

The woom EXPLORE e 5 stops helping at 25 km/h (15.5 mph), well under the 20 mph Class 1 limit, so in California it rides under the Class 1 rules. Our e-bike laws guide covers the classes in full.

Mistakes to avoid

Each of these costs money or a fall.

• Buying the 26 inch bike to grow into. The EXPLORE e 6 starts at 140 cm, and a 10 year old who can’t reach the ground at a stop will fall at a stop.
• Reading “ages 8 to 9” as a ceiling. Commencal names the age to start, and at 16.6 kg the bike is 64% of a median 8 year old.
• Judging by motor torque. A 60 Nm Bosch motor on a 16.6 kg bike gives a light child more push than they can steer.
• Riding in the dark without lights. A 2026 study of 878 police-reported crashes in California riders aged 18 and under linked serious injury to low light and to riding without a helmet. Our helmet guide covers fit for small heads.

Where these numbers come from

Bike weights, sizes, speeds and prices come from woom, STACYC, Commencal and Razor’s own pages, checked November 12, 2026. The Cube figures come from two retailer listings, Certini in the UK and Cube Store Brilon in Germany, because cube.eu returned an error every time. The retailers list 55 Nm, while a cube.eu search snippet showed 60 Nm, so we left torque out. Child heights and weights are the CDC 2000 growth charts at the 50th percentile. The 40% line is woom’s guidance, not a pediatric standard, and the shares are our calculation. Laws are from each statute or regulator, listed below.
