Double Crown Fork Mono Rear Shock and Hydraulic Discs on TrailLong Trail Miles on a Single Charge

A fat tire electric dirt bike with a moto-style step-over frame, a 3000W peak brushless geared hub in the rear wheel, and a 60V 30Ah pack worth 1800Wh in a key-locked box at the frame center. A double crown suspension fork and a mono coil shock, hydraulic disc brakes at both wheels and 20 x 4.0 knobby tires. Listed at 43 to 68 miles per charge, a 20 mph throttle setting, and a 330 lb load rating, in graphite grey.

The format is a small electric dirt bike rather than a bicycle: a welded carbon steel step-over frame, a moto seat, a high front fender, and the battery box sitting in the spine of the frame where the mass stays centered. The pack locks with a key and lifts out for charging at a desk or on a workbench. It suits fire roads, field tracks, sand and snow, and the paved last mile of a commute where the hard surface runs out.

The trade is honesty about rules. A 3000W throttle bike is not a street motorcycle and in many states it sits outside the Class 1 to 3 e-bike definitions, so it belongs on private land and trails where the law allows. The throttle setting is 20 mph as configured, the pedals and the seven gears are real, and a helmet is not optional at any speed.

A Dirt Bike Frame With Pedals

The frame is welded carbon steel in a step-over layout, braced at the rear triangle where a 3000W hub pulls hardest. Steel is heavier than aluminium and it is also what keeps a frame like this affordable and repairable, and the welds are the part to inspect after a hard season.

The motor is a 3000W peak brushless geared hub in the rear wheel, with the controller inside the frame instead of a box under the seat. A geared hub trades a little top-end for pull from a stop, which is what a loaded bike on a steep track actually needs.

Behind it sits a seven-speed Shimano drivetrain with a thumb shifter, so the pedals are a real fallback when the pack runs flat and a way to keep the motor in its efficient band on climbs. The bike pedals like a heavy bicycle, which is exactly what it is.

• Welded carbon steel step-over frame
• 3000W peak brushless geared hub
• Five assist levels and a walk mode
• 7-speed Shimano thumb shifter
• Twist throttle on the bars
• LCD with speed, battery and assist

On throttle alone the bike pulls to about 20 mph and holds it on flat ground, the setting it ships with. The seat is a moto unit, the bars are wide, and the LCD on the left keeps speed, battery state and assist level in one place.

Where the Miles Come From

The pack is 60V 30Ah, worth 1800Wh, and it lives in a key-locked box at the center of the frame rather than hiding in a tube. It lifts out for charging at a desk or in an apartment, which matters when the bike lives in a garage without power. A management system balances the cells and guards against overdraw and over-discharge, and the supplied 60V charger fills it from empty in about five to six hours.

We quote 43 to 68 miles per charge, the conservative span: 43 miles on throttle alone and up to 68 miles with pedal assist on level ground. The factory listing for this bike runs higher, 51 to 93 miles, which assumes a light rider, low assist and perfect ground. Cold weather, hills and soft sand all cut into the number, so treat 68 as the ceiling and plan around the rides you actually take.

Riding style decides the rest. Five assist levels let you trade effort for miles, a walk mode helps you push the bike up a slope, and tire pressure matters more than most riders expect: the fat casings want around 20 psi on pavement and 8 to 10 psi when sand or snow is on the menu. Acceleration is smooth from a standstill.

Fire Roads Sand and Snow

Up front a double crown suspension fork takes preload adjustment, and under the seat sits a single coil shock with the red spring that shows in every photo. Together they keep the wheels planted on washboard and rocky track, and hydraulic discs at both ends park it predictably.

The 20 x 4.0 knobby casings are the other half of the story: wide enough to float over soft sand and snow at low pressure, and hard enough to roll cleanly when the commute is mostly pavement.

• Fire roads and field tracks
• Sand and snow at low tire pressure
• Campgrounds and private ground
• Cold starts with the walk mode
• Long climbs where the geared hub pulls
• Not for stairs or a roof rack

What's in the Box

The bike arrives 85 percent assembled: fit the handlebar, the front wheel and the pedals with the supplied toolkit, then charge the pack fully before the first ride. Check both brake rotors for true, set the bars square to the fork, and recheck the axle nuts after the first ten miles.

Color and Finish

One finish: graphite grey across the frame, the shrouds and the battery box, with black fork legs, black rims and knobby tires under it. The bright pieces are the red brake calipers front and rear and the red coil spring under the seat, and the high front fender keeps the moto look honest.

The wear points are the fork stanchions and the chainstay, which want a wipe after wet and muddy rides, and the seat corners where a strap rubs.

Battery Care and Maintenance

Charge the pack indoors between 10 and 30 degrees C, and never charge a frozen pack: plating a cold cell costs capacity permanently, so let it warm first. Give it one full charge before the first ride, unplug when the light turns green, and store it around 60 percent charge if the bike will sit for a month.

Each ride starts with a tire pressure check against the terrain and a squeeze of both brake levers. Hydraulic pads want a look every 200 miles, since a worn pad scores the rotor, and the chain wants a wipe and a drop of lube after wet rides. Check the spoke tension after the first few outings, keep the axle nuts tight, and never aim a pressure washer at the connectors or the charge port.
