A 960Wh Pack a Long Bench and Four Hundred Pounds of Rated LoadLong Range and Room Left Over Here

An enduro-shaped 20-inch fat bike with a 1500W hub, a 48V 20Ah pack worth 960Wh in the frame and 62 miles of pedal assist. A long bench on twin red coil shocks, a sprung fork, mechanical discs at both ends and 20 x 4.0 tyres on spoked rims. It is 67.7 inches long, weighs 81 lb, and the listing rates it at 150 kg. Its geometry is the part that decides whether it suits you: 67.7 inches long with a 32.6 inch seat, so it wants a taller rider and a doorway wider than a hallway.

The frame is a grey enduro loop with a black battery box standing in for a tank, a long flat bench and a round headlamp on a bracket above the front mudguard. The forks are a single-crown unit with gold-anodised adjusters, and the two rear shocks show red springs and a reservoir each.

The geometry is worth reading before you buy: 67.7 inches long, a 43.3 inch wheelbase, a 32.6 inch seat and a 27.3 inch bar. That is a bigger footprint than most 20-inch fat bikes, which is what makes it stable at speed and what makes it awkward in a hallway.

Enduro Frame and Twin Red Shocks

The frame is a grey enduro loop with a black box on the down tube that carries the battery and the controller, a long flat bench and a round headlamp in a black shell above the front mudguard. The fork is a single-crown unit with gold adjusters and the two rear shocks show red springs and reservoirs.

The wheels are 20 x 4.0 knobbys on spoked rims with gold-anodised spoke nipples. Spokes can be trued with a key, and the wide casing is what lets an 81 lb bike cross sand instead of digging in. Run them at 15 psi on pavement and 8 on soft ground.

Suspension is a sprung fork up front and two coil shocks at the rear, both adjustable at the collar, which is more travel than a hardtail 20-inch bike offers. Brakes are mechanical cable discs at both ends, and the drivetrain is a Shimano seven-speed derailleur with a trigger shifter.

• Frame: grey enduro loop
• Battery: 48V 20Ah in the down tube box
• Wheels: 20 in spoked, 4.0 knobby
• Fork: single crown, gold adjusters
• Rear: twin coil shocks, red springs
• Brakes: mechanical cable disc

Fitted as shipped: the round headlamp, front and rear mudguards, the long bench, a kickstand and the pedals. The bars carry the throttle, the assist switch, the brake levers and a display, and the frame box has its own lock and charge port on the side.

1500W and 960Wh

The motor is a 48V 1500W rear hub, and with a 960Wh pack behind it the bike is built for distance rather than a short blast. The listing quotes 62 miles in pedal assist, which is the figure to plan around: throttle-only riding, sand and a heavy rider all cut into it.

The pack is 48V 20Ah, 960Wh, in the boxed down tube. It is the second largest battery in this group, and it is the reason the bike weighs 81 lb rather than 60. Charging is through the port on the box, so the bike stays where it is parked and the battery does not come indoors.

Two ratings to keep apart: the listing rates the payload at 150 kg, or about 330 lb, while the poster printed on the bike quotes 400 lb. This page uses the 150 kg figure because it is the one stated in the product listing, and a rider over 330 lb should ask before ordering rather than assume the higher number.

Who It Fits and How It Rides

The seat sits at 32.6 inches and the bars at 27.3 inches wide, which suits riders from about 5 ft 7 in upward according to the size chart. The 150 kg rating covers a heavy adult with a pack, and the long wheelbase keeps the bike planted at speed. It is not a machine for a short rider.

On gravel, packed dirt and snow it tracks straight and the twin shocks keep the bench level, and the fat casing floats. On pavement it is long, heavy and slow to steer, and the knobbys hum. It is a fire road and trailhead bike, and it needs a ramp rather than a roof rack.

• Fire roads and gravel tracks
• Trailheads and campgrounds
• Riders from 5 ft 7 in upward
• Not for short riders stairs or bike lanes

What's in the Box

Before the first ride: fit the front wheel and torque the axle, set the bars square to the fork, set the rear shock preload for your weight, bed the cable discs in with ten firm stops and charge the pack. Budget 40 to 60 minutes, and check every fastener after the first hour of riding.

Color and Finish

The frame is a light grey with a matte clear coat, the battery box and bench are black, and the two rear springs are red. Gold appears on the spoke nipples and on the fork adjusters, which is the detail that stops the bike reading as a plain grey machine.

Touch-up paint in the frame grey is available on request. The wear points are the battery box where a boot rubs it, the bench edges and the fork lowers.

Battery Care and Maintenance

Charge between 20 and 90 percent for everyday use and take it to full about once a month. The pack lives in the down tube box, so charge it where the bike is stored and keep that spot above freezing. If the bike will sit for a month, leave it around half charge rather than full.

Check tyre pressure before every ride at 15 psi on pavement and 8 on soft ground, and check the spokes and axle nuts after the first 50 miles. The cable discs need the barrel adjuster turned as the pads wear. Keep the chain oiled so the seven gears shift, and set the shock preload again whenever the rider changes.
