The HHH SZ is a 2000W electric dirt bike for teens and lighter adults who want real trail performance without gas, oil changes or engine noise. A 190 N·m mid-drive motor and a 48V 21Ah lithium battery give it 35 mph top speed and up to 31 miles of range. It rolls on a 14" front and 12" rear knobby wheel setup, with hydraulic disc brakes and dual rear shocks.

2000W Mid-Drive Motor and 190 N·m of Torque
The SZ uses a mid-drive motor. It sits in the frame between the wheels and drives the rear wheel through a chain, rather than sitting inside the wheel hub. That brings two advantages:
- Better balance and suspension. The motor's weight sits low and central, which keeps the bike balanced in the air and over bumps. The rear suspension moves freely instead of carrying a heavy hub motor.
- Stronger climbing. Driving through the chain gives the motor gearing advantage, so all 190 N·m of torque reaches the ground. The SZ pulls up steep dirt climbs that stall hub-motor bikes.
Electric torque is instant, with no clutch to slip and no gears to miss. That makes the SZ easier to learn on than a gas dirt bike, but it also means a heavy throttle hand launches it hard. New riders should start with gentle throttle inputs on open, flat ground.
48V 21Ah Battery: Range and Charging
The 48V 21Ah lithium battery stores about 1,008 watt-hours. That's enough for up to 31 miles per charge. Real range depends on rider weight, terrain, temperature and how often you ride at full throttle. Expect less on steep hills or in cold weather, and more on flat trails at moderate speed.
The included 3.0A US-standard charger refills the battery in 6–7 hours, so an overnight charge has it ready for the morning.
The charging port is mounted high on the frame, above the mud and water splash zone, which keeps grit out of the connector and protects it from wear.
Battery care:
- Charge on a hard, non-flammable surface and away from anything combustible.
- Let the battery cool after a hard ride before plugging in.
- For storage longer than a few weeks, keep the battery around half charge in a cool, dry place and top it up monthly.
Hydraulic Brakes and Full Suspension
Hydraulic disc brakes stop the SZ firmly with a light squeeze of the lever. That matters on a 35 mph bike, especially for younger riders with smaller hands. Hydraulic brakes also keep consistent feel in dust and mud, where cable brakes stretch and fade.
Front suspension and dual rear shock absorbers soak up roots, ruts, rocks and jump landings, keeping the tires in contact with the ground for grip and control.
The 14"/12" wheel combination is the standard for this class of electric dirt bike:
- Larger front: rolls over obstacles.
- Smaller rear: keeps the bike compact and quick to turn.
Safety and Controls
- Key ignition. The bike won't power on without the key, so parents control when it's ridden.
- Magnetic kill switch. A lanyard attaches to the rider. If they come off the bike, the magnet pulls free and the motor cuts out instantly.
- Digital display. Shows speed, mileage, battery level and ride time, so riders know when to head back before the battery runs low.
Rider Fit and Who It's For
The SZ measures 60" long, 29" wide and 40" tall, and weighs 110 lbs with the battery. Rider capacity is 165 lbs. That's the most important fit number. It suits most teenagers and smaller adults. Heavier riders will overload the motor, battery and suspension and should look at a larger electric or gas dirt bike.
With a 35 mph top speed and 2000W motor, this is a performance bike, not a toy. Electric dirt bikes in this 2000W, 14"/12" class are generally recommended for riders 13 and older. Every rider needs a helmet, goggles, gloves, boots and adult supervision.
The SZ is built for off-road use on private land, trails and tracks. It has no road lighting or signals and is not street legal.

Electric vs. Gas: Why Choose the SZ
| HHH SZ Electric | Typical 110–125cc gas pit bike | |
|---|---|---|
| Noise | Near silent | Loud exhaust |
| Maintenance | Chain, brakes, tires | Plus oil, air filter, spark plug, carburetor |
| Fuel | Wall outlet | Gasoline |
| Power delivery | Instant torque, no clutch | Gears or semi-auto |
| Neighbors | Rides quietly in backyards and near homes | Noise complaints common |
Choose electric if you ride close to home, want low maintenance or have noise-sensitive neighbors. Choose gas if you need all-day range without recharging.

HHH SZ Electric Dirt Bike: Questions Answered
How fast does the HHH SZ go?
Up to 35 mph, depending on rider weight, terrain and battery charge.
How far can it go on one charge?
Up to 31 miles. Hills, heavier riders, cold weather and constant full throttle reduce range.
How long does it take to charge?
6–7 hours with the included 3.0A charger.
What age is it for?
It's built for teens and lighter adults up to 165 lbs. Bikes in this 2000W class are generally recommended for ages 13 and up, with adult supervision and full protective gear.
Is it street legal?
No. It's an off-road electric dirt bike for private property, trails and tracks.
What does the magnetic kill switch do?
A lanyard clips to the rider. If they fall off, the magnet detaches and the motor shuts off immediately.
What's the advantage of a mid-drive motor?
Better weight balance, freer suspension movement and stronger hill climbing than a hub motor, because power runs through the chain and rear sprocket.
