An 1104Wh Tank Case on the Down Tube and Hydraulics to MatchTan Sidewalls and Bold Tank Lines

A 750W rear hub, a 48V 23Ah 1104Wh pack in a tank-style case on the down tube, 26 x 4.0 tires with tan sidewalls, a suspension fork, hydraulic disc brakes and a rear rack. It is listed at up to 29 miles on pedal assist, 31 mph and 330 lb, and it comes in three finishes: sand khaki, matte black and forest green. Nothing else needs buying: the rack, the fenders and the light are already fitted, and the case comes off for charging.

The battery case is the first thing you notice, and it is honest about what it is: a rectangular block bolted to the down tube with a green charge indicator on its side, rather than a pack hidden inside the frame. That makes the level readable at a glance and the whole case removable in seconds, which matters more on a 1104Wh bike than the tidier look of an integrated pack. It also means a replacement is a case rather than a frame.

Three colourways in one listing is unusual at this price, and it changes who the bike is for. Sand khaki reads as a beach and desert bike, forest green disappears into a treeline, and matte black is the one that hides chain oil. Order the colour for where you ride rather than for the photo, because a fat bike is a large object in a hallway.

Tank Case and Tan Sidewalls

The frame is aluminium with a step-over triangle and a battery case clamped to the down tube rather than hidden inside it. The case carries its own charge window and a key lock, so the level is visible while the bike is parked and the pack comes off in one motion.

Up front there is a suspension fork and behind the saddle a rigid triangle that carries the rack. On 26-inch wheels with four-inch tires that split suits a fat bike: the casing does most of the work, the fork takes the hits, and the rigid rear keeps a loaded rack from bouncing against a pivot.

The tires are 26 x 4.0 with tan sidewalls and a knobby tread, which is a look as much as a specification. On gravel and packed sand the casing floats and grips; on pavement the tread hums, and the tan walls show dirt faster than black ones would.

• Frame: aluminium, step-over
• Battery: 1104Wh tank case on the down tube
• Fork: suspension, rigid rear triangle
• Brakes: hydraulic disc, front and rear
• Tires: 26 x 4.0 tan sidewall, knobby
• Drivetrain: 7-speed, colour LCD

Fitted as shipped: front and rear fenders, the rear rack with a guard, a round LED headlight on the fork crown, a colour LCD on the bars and the battery keys. The 7-speed drivetrain is there for the day the pack runs flat, not for changing gear at 31 mph.

750W Hub and 1104Wh in a Case

The motor is a 750W brushless rear hub as this listing specifies it, and the brand does not publish a peak figure for this configuration, so 750W is the number to quote rather than a short-duration claim. On four-inch tires that is enough to keep a loaded bike moving through gravel and packed sand, which is the job, and not enough to spin the wheel and dig in. It is a geared hub, so it freewheels when you stop pedalling.

The pack is 48V 23Ah, 1104Wh, in the tank case with a green level indicator on the side. It charges on the bike through a sealed port or off it on a bench, and the case is the part that comes indoors in winter, because a 1104Wh pack left in a freezing garage loses capacity faster than one kept at room temperature. A full charge is an overnight job.

Range is listed at up to 29 miles on pedal assist, and the words up to matter: that figure assumes a steady pace on level ground, so sand, a headwind or a heavy rider will land nearer twenty. A 1104Wh pack is large, but a fat tire bike spends that capacity on rolling resistance rather than speed.

Who It Fits and How It Rides

One frame size covers riders from about 5 ft 6 in to 6 ft 4 in, and the fat tires raise the saddle compared with a normal 26-inch bike. The standover is tall enough that shorter riders should sit on one before ordering, and the length of the bike matters if it has to live in a hallway.

On gravel and packed sand it is calm and stable, and the hydraulic discs earn their place: they stop a 330 lb combination with two fingers where cable discs would need a full hand. On pavement the tread hums and the steering is slow.

• Beach towns, fire roads and farm tracks
• Campgrounds and hunting trips with a loaded rack
• Rail trails where stability beats speed
• Not for tight singletrack, stairs or fast group rides

What's in the Box

Before the first ride: fit the front wheel and check the axle, set the fork preload for your weight, bed the hydraulic brakes in with ten firm stops from a walking start, and check the rack bolts before you load it. Charge the pack fully. Keep the carton for the first month.

Color and Finish

Sand khaki, matte black and forest green are the three finishes, each with black rims, a black fork, a black cockpit and a black rack. The khaki is the one in the photographs and the green is the rarest of the three, which is usually the one people ask for once they see it in daylight.

Touch-up paint is available on request in all three colours. The wear points are the battery case where a knee rubs it and the chainstay under the chain.

Battery Care and Maintenance

Charge the pack between 20 and 90 percent for daily use and take it to full about once a month so the management system can balance the cells. An 1104Wh case takes most of a night, so start it in the evening, and bring it indoors rather than leaving it in a cold garage through a winter.

Check tire pressure before every ride: 18 to 20 psi on pavement, 8 to 12 psi on sand and snow, and use a gauge rather than a thumb on a four-inch casing. Check the hydraulic pads monthly, the fork stanchions after a wet ride, and the rear spoke tension after the first 20 rides, since a hub motor loads that wheel harder than a bicycle hub does.
