Hydraulic Discs Dual Rear Coils and a Lockable Rear Rack PackBackrest Miles on Wide Kenda Tires

A fat tire electric dirt bike with a welded carbon steel step-over frame, a 1000W brushless geared hub in the rear wheel, and a 48V 15Ah pack worth 720Wh in a key-locked box behind the seat. A suspension fork and dual rear coil springs, hydraulic disc brakes at both wheels and 20 x 4.0 Kenda Krusade tires. Listed at 20 to 37 miles per charge, a 20 mph throttle setting, and a 330 lb load rating, in black with a backrest.

The format is a small electric dirt bike rather than a bicycle: a welded carbon steel step-over frame, a long saddle with a backrest pad, and the battery box sitting on the rear rack where a cargo bag would go. 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 1000W 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 head tube and the bottom bracket where a 1000W hub pulls hardest. Steel is heavier than aluminium and it is also what keeps a frame like this affordable and repairable.

The motor is a 1000W brushless geared hub in the rear wheel, rated 70 to 80 newton meters of torque, with the controller inside the frame. A geared hub trades a little top-end for pull from a stop, which is what a loaded bike on a steep track 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
• 1000W 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 saddle is long with a backrest pad, the bars wear mirrors, and the LCD on the left keeps speed, battery state and assist level in one place.

Where the Miles Come From

The pack is 48V 15Ah, worth 720Wh, and it sits in a key-locked box on the rear rack rather than hidden 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 48V charger fills it from empty in about five to six hours.

We quote 20 to 37 miles per charge, the conservative span: about 20 miles on throttle alone and up to 37 miles with pedal assist on level ground. The factory platform page runs higher, 60 to 80 kilometers, which assumes a light rider, low assist and perfect ground. Cold weather, hills and soft sand all cut into the number, so treat 37 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 suspension fork takes the sting out of ruts and roots, and under the seat two coil springs keep the back wheel tracking instead of skipping. Together they keep the wheels planted on washboard and rocky track, and hydraulic discs at both ends park it predictably once bedded in.

The 20 x 4.0 Kenda Krusade 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.

• Field tracks and fire roads
• Errands with a bag on the rear rack
• Short two-up trips behind the backrest
• Snow days and sandy shoulders
• 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: black across the frame, the fenders, the rack and the battery box, with black fork legs, black rims and Kenda casings under it. The bright pieces are the orange brake calipers and the clear lens of the round headlight, and the finish is a powder coat over steel.

The wear points are the fork stanchions and the chainstay, which want a wipe after wet and muddy rides, and the backrest pad 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.
