Hydraulic Discs a Rear Coil Shock and a Lockable Down Tube PackMoped Miles on Wide Kenda Tires

A fat tire electric dirt bike with a welded steel moped-style frame, a 1000W brushless hub in the rear wheel, and a 48V 15Ah pack worth 720Wh in a key-locked case on the down tube. A suspension fork and a rear coil shock, hydraulic disc brakes at both wheels and 20 x 4.0 Kenda Krusade tires. Listed at 25 to 37 miles per charge, a 31 mph top speed, and a 331 lb load rating, in black with a rack and backrest.

The format is a small moped-style electric dirt bike rather than a bicycle: a welded steel frame, a long saddle with a backrest pad, a rear rack, and the battery case sitting on the down tube where the mass stays low. 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 that makes 31 mph 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. Check your local rules, the pedals and the seven gears are real, and a helmet is not optional.

A Moped Frame With Pedals

The frame is welded steel in a moped layout: a long saddle with a backrest pad, a rear rack behind it, and a front basket over the wheel. Steel is heavier than aluminium and it is also what keeps a frame like this affordable and repairable.

The motor is a 1000W brushless hub in the rear wheel, with the controller inside the frame instead of a box under the seat. A hub motor keeps the drivetrain simple, which is what a bike that sees wet gravel and sand actually benefits from.

Behind it sits a seven-speed derailleur with a bar 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 steel moped-style frame
• 1000W brushless rear hub
• Adjustable pedal assist levels
• 7-speed derailleur with bar shifter
• Twist throttle on the bars
• LCD with speed, battery and assist

On throttle alone the bike pulls to about 31 mph and holds it on flat ground, the figure the maker lists. The mirrors tuck in for a doorway, the rack takes a bag, and the LCD on the bars 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 case on the down tube rather than bolted outside it. 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 charger fills it from empty in about three hours.

We quote 25 to 37 miles per charge, the span the maker lists: the low end on throttle alone and the high end with pedal assist on level ground. Hills, cold weather, soft sand and a heavy load all cut into it, so treat 37 as the ceiling and plan around the rides you actually take, not the brochure. Charge soon after a ride rather than parking it warm and empty overnight.

Riding style decides the rest. Assist levels let you trade effort for miles, 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. Keep the charge port covered between rides so moisture stays out. 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 saddle a rear coil shock keeps 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.

• Grocery runs and coffee loops
• Errands with the front basket and rear rack
• Bike paths and broken pavement
• Gravel lots and sandy shoulders
• Evening commutes under the headlight
• 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 rack, the basket and the battery case, with black fork legs, black rims and Kenda casings under it. The bright pieces are the clear lens of the round headlight and the chrome of the mirrors, 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.
