Full Suspension Four Inch Tires and a Pack That Lasts the DayEnduro Blood With Better Manners

A 1500W rear hub with 80 Nm, a 48V 20Ah 960Wh pack in a case on the frame, 20 x 4.0 knobby tires, an inverted double-crown fork with twin coil shocks at the rear and hydraulic disc brakes. It is a moped-shaped enduro bike for trail use, listed at 31 to 62 miles, 82 lb and a 330 lb load rating, and it comes in gold, black or light grey. The bench takes a passenger, the battery case lifts off in one motion for charging, and the front rack hoop is bolted on rather than clipped.

The frame is a moped spine rather than a bicycle diamond: two rails running from the steering head to the seat, a long bench on top and a battery case bolted between them where a fuel tank would sit. That layout is why the bike looks the way it does, and it is also why the weight sits low and central instead of hanging off a rear rack. What it costs is height: the spine puts the bars high and the bench is fixed, so a short rider struggles at a stop.

What separates it from the fat-tire commuters in this range is the suspension and the brakes. An inverted double-crown fork and a pair of coil shocks at the back give it travel at both ends, and hydraulic discs with 180 mm rotors are what let a 82 lb bike carrying 330 lb of rider and load stop on a downhill without fading.

Moped Spine and Full Suspension

The frame is carbon steel in a moped shape, with two rails from the head tube to the seat and the battery case clamped between them. Steel is the heavy choice and the right one here: the frame has to hold 82 lb of bike and 330 lb of rider without flexing,.

The battery sits in that case rather than inside a tube, so the charge window is visible while the bike is parked and the pack lifts off in one motion. That is the practical difference on a 960Wh bike: you bring a case indoors rather than a whole bicycle.

Suspension is at both ends. Up front there is an inverted double-crown fork, and at the rear a pair of coil shocks with visible red springs. On four inches of air in each tire that is a lot of travel for a 20-inch wheel, and it keeps the bike from skipping across a washboard track at speed.

• Frame: carbon steel moped spine
• Battery: 960Wh case between the rails
• Fork: inverted, double crown
• Rear: twin coil shocks, red springs
• Brakes: hydraulic disc, front and rear
• Tires: 20 x 4.0 knobby

Fitted as shipped: front and rear fenders, a front rack hoop over the wheel, a round grille headlight, a kickstand and the battery keys. The bars are wide with a moto bend, and the brake levers are hydraulic with motor cut-off switches.

1500W Hub and 960Wh of Pack

The motor is a 1500W brushless rear hub quoted at 80 Nm. That torque figure is what moves a 82 lb bike and a rider away from a stop on loose ground, and it is the number to compare rather than the wattage. A geared hub rather than direct drive, so it freewheels when you stop pedalling, and the controller is sine wave rather than square, which is why it pulls away quietly instead of whining.

The pack is 48V 20Ah, 960Wh, in the case on the frame. It charges in place through a sealed port or off the bike, and a full charge is an overnight job on the supplied charger. Because the case is external, it is the part that comes indoors in winter, where bikes left in a cold garage lose a third of their capacity. A replacement later is a case rather than a frame.

Range is listed at 31 to 62 miles, and the spread is the honest part: 31 is throttle-heavy riding on soft ground and 62 is pedal assist on a hard surface. Cold weather, sand and a headwind pull both down, so plan a trail day around 35 miles of real riding rather than the headline figure, and charge at the trailhead if the day is long.

Who It Fits and How It Rides

The bench does not adjust in height, so the range is narrower than the frame suggests: roughly 5 ft 4 in to 6 ft 3 in. Taller riders will feel their knees come up and shorter riders will find the step-in easier than a saddle-and-post bike, so sit on one before ordering.

On gravel, dirt and packed sand it is stable and the twin shocks keep the bench level. On pavement it is quick and noisy from the knobby tread, and at 82 lb it is not a bike you lift onto a rack alone.

• Fire roads, farm tracks and packed dirt
• Campgrounds and short backcountry trips
• Two-up short trips on a bench seat
• Not for tight singletrack, stairs or commuting in rain

What's in the Box

Before the first ride: fit the front wheel and check the axle, set the fork and shock preload for your weight, bed the hydraulic brakes in with ten firm stops from a walking start, then charge the pack. Get help lifting it out of the carton at 82 lb,.

Color and Finish

Gold, black and light grey are the three finishes, each with a black battery case, black fork lowers, black fenders and a black bench. The gold is the loudest of the three and the grey is the one that hides dust, which matters on a bike that spends its life on dirt.

Touch-up paint is available in all three colours, and matte finishes are harder to spot-repair than gloss. The wear points are the battery case and the chainstay.

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 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 at 15 to 20 psi on pavement and 8 to 12 psi on dirt, and check both axles and the shock preload after the first 50 miles. Check the hydraulic pads monthly and the spoke tension on the rear wheel after the first 20 rides, since a hub motor loads that wheel harder than a bicycle hub does.
