A childs dirt bike should match the rider's age, height and experience, and an electric dirt bike for kids has advantages: it is quiet, there is no clutch or gear shifting, and many models let a parent limit the top speed. This guide compares the kids and youth electric dirt bikes in our range by age, power and price. All specifications are the figures in our product listings, and every bike should be used under adult supervision on private property or a suitable off-road area.
Ages 3 to 6: a first childs dirt bike
The EDBA Moto 50 beginner kids electric motorbike is listed for ages 3 to 6, with a 250 watt motor, a 6 km/h top speed, a 14 kg weight, up to 60 minutes of ride time and a maximum rider weight of 30 kg. It has a parental remote kill switch and key lockout. It is $1,290 AUD.
Ages 4 to 10: factory youth bikes
The KTM SX-E 5 and the Husqvarna EE 5 are both listed for ages 4 to 10 with a 1,100 watt motor, a 20 km/h top speed, an 80 minute charge time and a 26 kg weight. The KTM has three parent-selectable power modes (20, 50 and 100 percent). The KTM is $7,990 AUD and the Husqvarna is $7,490 AUD.
Ages 6 to 14: trials and training
The OSET 20.0 Racing Junior is listed for ages 6 to 14 with a 600 watt motor, a 24V 20Ah lithium battery, up to 3 hours of ride time, a 15 km/h top speed and a 22 kg weight. A parent can adjust the maximum speed. It is $4,290 AUD. Our OSET bikes review goes into detail.
Junior motocross with a parental app
The Torrot Motocross Two junior has a 1,500 watt motor, a 48V 10.4Ah quick-swap battery and a 32 kg weight, with a Bluetooth parental app limiter. It is $3,690 AUD.
Teens and smaller adults
The Segway X160 compact youth dirt bike has a 3,000 watt motor, a 48V 20Ah battery, a 50 km/h top speed and up to 65 km of range at 48 kg, at $4,690 AUD. The Razor MX650 is listed for ages 13 and up with a 650 watt motor, an 18 km/h top speed and a maximum rider weight of 81 kg, at $899 AUD.
How to choose
Start with the child's age and height, not the power figure. Pick a bike with speed limiting, so the speed can rise as skills improve. Check the weight, because a bike a child can pick up after a fall is easier to manage. Buy protective gear at the same time as the bike.
Where to ride
These bikes are intended for private property and supervised off-road use. Rules on young riders differ by state, so read our guide on what age kids can ride electric dirt bikes and check your state authority.

How to size a childs dirt bike
Size by the rider, not by the age printed on the box. The bikes in our range are listed for different age bands: the EDBA Moto 50 for ages 3 to 6, the KTM SX-E 5 and Husqvarna EE 5 for ages 4 to 10, the OSET 20.0 for ages 6 to 14 and the Razor MX650 for ages 13 and up. The Torrot Motocross Two is described as a junior bike for riders aged 6 to 11, and the Segway X160 is described as suiting riders roughly 150 cm to 170 cm tall. A child should be able to reach the ground comfortably, hold the bars with a relaxed bend in the elbows and reach the brake levers without stretching.
Weight matters more than power
A lighter bike is easier for a child to pick up after a fall and easier to steer. The listed weights run from 14 kg for the EDBA Moto 50 and 22 kg for the OSET 20.0 to 26 kg for the KTM SX-E 5 and Husqvarna EE 5, 32 kg for the Torrot and Razor, and 48 kg for the Segway X160. If a child cannot comfortably hold the bike upright when stopped, it is too heavy or too tall for them yet.
Speed limits and parental control
Control matters as much as speed. The listed top speeds are 6 km/h for the EDBA Moto 50, 15 km/h for the OSET 20.0, 18 km/h for the Razor MX650, 20 km/h for the KTM and Husqvarna and 50 km/h for the Segway X160. The KTM has three parent-selectable power modes at 20, 50 and 100 percent. The OSET has an infinitely variable speed dial and a parent-adjusted maximum speed. The Torrot Motocross Two has a Bluetooth app that lets a parent control top speed, acceleration sensitivity and engine braking. The EDBA Moto 50 has a parental remote kill switch and key lockout.
Battery, run time and charging
Run time is a practical matter for a child's session. The EDBA Moto 50 is listed at up to 60 minutes of ride time, the OSET 20.0 at up to 3 hours, and the Razor MX650 at up to 45 minutes. The KTM SX-E 5 and Husqvarna EE 5 charge in about 80 minutes on the standard charger. The Razor MX650 uses a 36V 12Ah sealed lead-acid battery, while the OSET uses a 24V 20Ah lithium-ion battery and the factory youth bikes use 48V lithium packs.
What the price ladder buys
The Razor MX650 at $899 AUD is the entry point for older kids. The EDBA Moto 50 at $1,290 AUD is a beginner bike for small children with the parental kill switch. The Torrot at $3,690 and the OSET at $4,290 add lithium batteries, app or dial control and more power. The Segway X160 at $4,690 is a teen and smaller-adult bike. The KTM at $7,990 and the Husqvarna at $7,490 add factory WP suspension and the brands' youth motocross design. Choose the rung that matches the child's skill, not the budget ceiling.
Electric or petrol for a child?
An electric childs dirt bike is quiet, has no clutch or gear shifting and needs no fuel mixing or oil changes. That makes it easier for a beginner and kinder to neighbours. The trade-off is run time, because the battery limits a session, and the cost of the higher-end factory bikes. Our guide to electric vs petrol running costs compares ownership costs for larger bikes.
Safety gear and supervision
Buy a certified helmet, gloves, boots and body protection at the same time as the bike, and supervise every ride. Keep the speed limiter on a low setting until the child shows consistent control, then raise it step by step. Read our e-bike safety guide for battery charging and storage advice.
Common mistakes to avoid
The most common mistakes are buying a bike that is too big so the child can grow into it, ignoring weight, leaving the speed limiter off and riding without gear or supervision. Another is treating a kids bike like a toy: store the battery cool and dry, charge it on a hard surface and keep the charger that came with the bike.
Where children can ride
These bikes are intended for private property and supervised off-road riding. Rules for young riders differ by state, so read our guide to what age kids can ride electric dirt bikes and check your state authority before riding anywhere other than private land.
