A Short Wheelbase and a 60 Nm Hub for Tight Technical GroundSmall Wheel and a Sharp Response

A 1000W peak rear hub, rated at 750W continuous, with a quoted 60 Nm, a 48V 20Ah 960Wh pack in the spine, 16 x 4.0 Chaoyang fat tires, hydraulic disc brakes and suspension at both ends, under a long bench seat between a front rack and a rear rack. It is listed at 50 to 67 miles and 28 mph with a 330 lb rating, and it is the shortest bike in this range that can still carry a passenger and a load at the same time, and the racks are why it works as a camping bike rather than a toy.

Sixteen-inch wheels on a bike this heavy is a deliberate choice, not a cost cut. The short wheelbase makes it flickable in a way a 26-inch fat bike is not, the low standover means almost anyone can get a foot down, and the smaller wheel multiplies the motor's torque at the tire, which is why a 1000W hub on 16 inches climbs a 30-degree grade that would stall the same motor on a 26. The trade is that a 16-inch wheel reads every crack in a pavement, which is what the fork and the rear shock are for.

The bench seat and the two racks are the reason the bike exists. A flat bench takes a passenger without a pad bolted on top of a rack, and with a rack at the front as well as the back the load can be split rather than stacked behind the saddle. That combination is what makes it a campsite and swap-meet bike rather than another fat-tire toy.

Short Wheels and Twin Racks

The frame is aluminium with the pack inside the spine behind the head tube, a bench seat over the rear wheel, and a rack at each end. At 16 inches the wheels are the smallest in this class, and the whole bike is barely longer than a doorway.

The front rack sits ahead of the bars and the rear one behind the bench, both bolted to the frame rather than clamped to a seat post. Splitting a load between them is the difference between a bike that steers and a bike that wheelies when you put a cooler on the back.

Suspension is a sprung fork at the front and a single coil shock at the rear, which is the right pairing on four-inch tires: the casing absorbs the small stuff, the fork and shock take the hits, and the bench stays level with a passenger aboard.

• Frame: aluminium spine, battery inside
• Seat: long bench, passenger length
• Racks: front and rear, frame mounted
• Fork and rear: sprung fork, coil shock
• Brakes: hydraulic disc, red calipers
• Tires: 16 x 4.0 knobby

Fitted as shipped: front and rear fenders, both racks, an LED headlight at the front and a tail light at the rear, a kickstand and an HID display on the bars. The tires are 16 x 4.0 Chaoyang with a knobby tread, so gravel and packed dirt are the natural surface.

1000W Hub and 960Wh of Pack

The motor is a 1000W peak brushless rear hub, rated at 750W continuous, with a quoted 60 Nm of torque. Peak is the figure for a launch or a climb, not one you can hold: the brand's own sheet lists 750W continuous, and that is the number to compare when you shop. The quoted climbing limit is 30 degrees, and on 16-inch wheels the torque arrives with more force at the tire than the same motor would put down on a bigger wheel.

The pack is 48V 20Ah, 960Wh, inside the spine and removable with a key. Charge time is six to eight hours on the supplied charger, so it is an overnight job. Because the case comes out, a winter charge happens indoors rather than in a cold garage, and because it sits in the spine rather than on a rack the bike still balances when you lift it by the frame with a passenger aboard.

Range is listed at 50 to 67 miles, and both figures assume one rider and no load. A passenger or a loaded rack pulls the low figure down, and so does sand or a long climb. Plan a campsite run around 35 miles and treat 67 as the flat-path best case with the assist turned down.

Who It Fits and How It Rides

One frame size covers riders from about 5 ft 2 in to 6 ft 2 in, and the low bench is what makes that range honest: the seat height does not adjust much, so tall riders will feel their knees come up and short riders will find it easier than a saddle-and-post bike of the same size.

On gravel and packed dirt it is stable and the short wheelbase is an advantage; on pavement the tread hums and the steering is quick at 28 mph. With a passenger aboard it is slower to stop.

• Campsites, farm tracks and gravel loops
• Two-up errands with a passenger on the bench
• Hauling gear split between two racks
• Not for tight singletrack, stairs or rain without mudguards fitted

What's in the Box

Before the first ride: fit the front wheel and check the axle, set the fork and shock preload for the weight you plan to carry, bed the hydraulic brakes in with ten firm stops, then charge the pack. Check the rack bolts before you load either end.

Color and Finish

Gloss white covers the spine, fork lowers, fenders and both racks, with black rims, a black bench, a black cockpit and red hydraulic calipers at both wheels. The red is the only accent, and against the white frame it is the part people point at first.

Touch-up paint in the matching white is available on request. The wear points are the rack decks, the bench edges 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. A 960Wh pack takes most of a night, so start it in the evening, and bring it indoors rather than leaving it on the bike in a cold shed.

Check tire pressure before every ride at 15 to 20 psi on pavement and 8 to 12 psi on dirt, and check the rack bolts and bench mounts whenever you carry a passenger or a load. 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. The rear shock preload is the setting most owners get wrong.
