HKM-7420755 Kids Electric Cross Motorcycle 24V 350W Mini Dirt Bike, 40 km/h Max Speed, 16 in Tires, Rear Disc Brake, 176 lb Capacity
HKM-7420755
350 Watts, Sixteen-Inch Wheels
The HKM-7420755 is a kids electric cross motorcycle built on a motorcycle layout: a 350 W brushless motor, a 24 V battery carried in an external compartment, and 16 in wheels with an off-road tread. Power is metered progressively from the throttle, the rear mechanical disc brake brings it back to a stop, and the steel-and-ABS composite frame carries riders up to 176 lb. A magnetic key ignition keeps start-up in adult hands.
Key Features
Six details that define how the HKM-7420755 is built and how it rides.
350 W Brushless Motor
A 350 W brushless motor delivers its pull in a smooth, progressive curve rather than one abrupt surge, which lets a new rider build throttle discipline while still leaving clear headroom for confident ones.
External Battery Compartment
The 24 V battery rides in a hard-shell compartment at the centre of the frame, protected from scrapes and visible at a glance, and recharges in 3-4 hours from a household outlet.
16 in Off-Road Wheels
Sixteen-inch wheels roll over ruts and broken ground that stop smaller bikes, and the five-spoke composite rims keep the rotating weight low where it matters most.
Rear Mechanical Disc
The rear wheel stops on a mechanical disc brake, consistent in wet grass and on dry dirt alike, with the lever placed at the grip where a small hand reaches it naturally.
Magnetic Key Ignition
The bike starts with a magnetic key, so the machine is dead until an adult decides otherwise - a simple answer to the question every parent asks before the first unsupervised minute.
176 lb Capacity
The steel-and-ABS composite frame carries riders up to 176 lb (80 kg), so the bike serves a long stretch of the growing years rather than one season.
Overview
A 24 V cross motorcycle with 16 in wheels, a rear disc and key ignition.
The HKM-7420755 is a kids electric cross motorcycle shaped by the same priorities as a full-size machine: a low centre of gravity, honest brakes and power that responds in proportion to the wrist. The 350 W brushless motor drives the bike to up to 24.85 mph (40 km/h), the 24 V battery recharges in 3-4 hours, and 16 in off-road wheels keep the ride composed on gravel, packed dirt and short grass. The steel-and-ABS frame carries up to 176 lb, a kickstand parks it upright, and the magnetic key ignition keeps every start-up deliberate.
Motorcycle Layout, Kid-Sized
Every control sits where a rider expects to find it.
Handlebar, brake lever, throttle and key switch are all in the positions a full-size motorcycle uses, so nothing has to be unlearned on the way up. The low seat keeps feet close to the ground at stops, and the upright bars put weight on the wrists rather than the shoulders, which is where young riders want it on a longer loop.
Full Specifications
What the motor, the battery and the chassis are made of.
Steel Core, Composite Panels
The chassis hardware carries the same standard as the motor.
The frame pairs a high-tensile steel core with ABS body panels, a split that puts strength where loads concentrate and forgives the scrapes that happen everywhere else. The 24 V battery sits in its own hard compartment low in the frame, keeping the centre of gravity down. Sixteen-inch wheels with an off-road tread carry the ride over broken ground, and the rear mechanical disc brake is placed where heat and mud bother it least.

Why Choose the HKM-7420755
Six further reasons families choose the HKM-7420755.
Room to Grow Into
Sixteen-inch wheels and a 176 lb capacity put the bike well beyond first-bike size, so the rider grows into it rather than out of it, and the frame carries them through years of weekend loops.
Progressive Power Delivery
The 350 W brushless motor responds in proportion to throttle input, so the bike is as calm as the wrist holding it - which is exactly what a learning rider needs from their first geared-up machine.
Starts Only With the Key
The magnetic key ignition means the bike cannot be switched on by a curious hand, so the machine stays parked until an adult is ready, and the key rides home in a pocket rather than on the bars.
3-4 Hour Recharge
The 24 V battery refills in 3-4 hours from a household socket, so a morning ride is ready again by the afternoon and an overnight charge covers the whole next day.
Composed on Broken Ground
Sixteen-inch wheels with an off-road tread hold their line on gravel, packed dirt and short grass, and the long wheelbase keeps the bike settled where small wheels start to dance.
Simple Weekly Care
A brushless motor, a mechanical disc brake and a sealed battery are the whole mechanical picture, so a short weekly check of wheels, brake and tire pressure keeps the bike ready to roll.
Frequently Asked Questions
Quick answers about the HKM-7420755 cross motorcycle.
How fast does it go?
Top speed is up to 24.85 mph (40 km/h) with a full battery on flat ground. Actual speed varies with rider weight and surface. The throttle is progressive rather than on-off, so speed can be kept well below the maximum while a new rider is still learning where their limits are.
How long does the battery take to charge?
A full recharge takes 3-4 hours from a household outlet with the included charger. Plug in after a morning ride and the bike is ready for the afternoon; an overnight charge covers a full day of sessions.
Is it suitable for my child?
The bike is built for young riders, with a low seat, upright handlebars and a 176 lb (80 kg) load limit. If your child can ride a balance bike or a pedal bike confidently and reach the ground at stops, the HKM-7420755 is a natural next step up. Always pair the first rides with a certified helmet and an open, traffic-free area.
What colours does it come in?
Black, red and yellow. The hardware is identical across the three - the same 350 W brushless motor, 24 V battery, 16 in wheels and rear disc brake - so the choice is purely about which colour your rider claims first.
Does it need assembly?
Minimal assembly is required, mainly fitting the handlebar, and the manual walks through each step. Most families complete it well inside half an hour with basic tools, and the brake and wheel checks in the first-ride section are worth doing before the key goes in.
Quick Troubleshooting
Common HKM-7420755 issues and what to check first.
The bike will not power on
Check the magnetic key first, because the bike is dead without it and a partially seated key will not complete the circuit. Turn the key fully and watch for the power-up response. If the key is in and there is still no response, connect the charger and allow a full 3-4 hour charge before trying again, as a deeply drained battery needs a complete cycle before it accepts normal use.
It slows down on hills or grass
Some slowdown on steep inclines and deep grass is expected at any power level, and a low battery reduces available output noticeably. Test top speed on flat ground with a full charge before assuming a fault, and confirm both tires are inflated to the pressure printed on the sidewall, because soft tires drag significantly.
The rear brake feels weak
A new disc brake needs a short bedding-in period, so apply it firmly a few times at low speed in an open area and expect the bite to improve over the first week. If the lever still feels soft, check that the rear wheel spins free with the lever released and that the rotor has not picked up mud or oil, which pads the disc unevenly.
The battery does not seem to last
Battery runtime depends heavily on throttle use, rider weight and terrain, and a battery left uncharged for weeks delivers less than a freshly cycled one. Recharge fully after every session rather than topping up in part, and if runtime keeps dropping on identical routes with a full charge, contact support with the purchase date to hand.

Read these notes before the first ride on the HKM-7420755.
The HKM-7420755 is a 24 V electric cross motorcycle for young riders up to 176 lb (80 kg). A certified helmet, gloves and closed-toe shoes are required for every ride, and the bike should only be ridden in dry conditions away from traffic, on gravel, packed dirt or other closed riding areas. The magnetic key should stay with an adult rather than in the bike, night riding is not recommended because the bike has no headlight, and the battery should be charged only with the included charger under adult supervision.
