A Mid Drive Motor Under a Moped Frame and a Colour Ring at NightA Quiet Glow That Follows You Home

A moped-frame fat bike with a 1000W peak mid drive motor, 60 Nm of torque and a 48V 15.6Ah pack worth 749Wh slung under the top tube. Twenty-inch 4.0 knobbys on spoked rims, a long bench seat, mechanical disc brakes at both ends and a seven-speed drivetrain. It is listed at 25 mph and 40 miles, carries 264 lb, and the motor carries a ring of colour-changing LEDs that you will either love or unplug, and a rear rack that takes a grocery run.

The frame is a single-loop moped shape with the battery box hanging under the top tube and a bench that runs from the seat tube to the rear axle. There is a plate on the frame where the battery sits and a matching one on the down tube, both carrying the brand, and the whole bike is black with a copper-brown saddle on the lighter version. The bars sweep back toward the rider, so you sit upright rather than over the front wheel.

What makes it different from the other mopeds in this range is where the motor sits. It is a mid drive in the frame, not a hub in the rear wheel, so the power goes through the chain and the rear suspension and the wheel bearings are not carrying it. The visible part is a round cover with a colour-cycling LED ring behind it, which is a feature rather than a specification, but it is the thing people notice first.

Moped Frame and Mid Mounted Motor

The frame is a single loop in black, with the battery in a box under the top tube and a bench seat that runs from the seat tube back over the rear wheel. Two pressed plates, one on the frame triangle and one on the battery box, carry the brand in white, and the fork is a straight-leg unit with a small round headlamp bolted to the crown.

The wheels are 20 x 4.0 knobbys on spoked rims, which is the size that keeps a fat bike stable at low pressure without making it impossible to lift. Spokes can be trued at home, and the rims are wide enough that the casing sits square instead of ballooning. Run them at 15 psi on pavement and 8 on sand.

The motor sits in the frame behind the seat tube, driving the rear wheel through the chain and the seven-speed derailleur. That is the layout that gives a moped its pull: the motor uses the gears, so a steep driveway is a gear change rather than a stall. The round cover over the motor carries a ring of colour-cycling LEDs, and the controller has overheat protection built in.

• Frame: single loop moped shape, black
• Motor: 1000W peak mid drive, chain final
• Battery: 48V 15.6Ah, under the top tube
• Wheels: 20 in spoked, 4.0 knobby
• Brakes: mechanical cable disc
• Drive: 7-speed derailleur

Fitted as shipped: a round LED headlamp, front and rear fenders, a rear rack behind the bench, a kickstand and the pedals. The brakes are mechanical cable discs at both ends, the bars carry the throttle, the assist switch and the levers, and there is a small dash between the grips for speed and battery state.

1000W Mid Drive and 749Wh

The motor is rated at 1000W peak with 60 Nm, and because it drives through the chain it feels stronger than the number suggests on a 20-inch wheel. The listed top speed is 25 mph, which is the Class 3 line in most states, and the listed climb is 30 degrees. There is a seven-speed derailleur behind it, so you can drop a gear and let the motor work at a speed it likes.

The pack is 48V 15.6Ah, 749Wh, and it lives in the box under the top tube, which keeps the weight low and central rather than over the rear wheel. The listed maximum range is 40 miles at low assist on flat ground; at 25 mph with the throttle open, plan on half that. Charging is through a port on the battery box.

Mid drive has one practical advantage over a hub on a bike like this: the motor is geared with you, so it is efficient on a climb instead of heating up. It also means the rear wheel is a normal wheel with a freewheel and a derailleur, which any bike shop can service. The trade is a little more noise from the chain run and a motor that sits where your heel wants to be if you pedal with your foot too far back.

Who It Fits and How It Rides

The bench is fixed and sits low, which suits riders from about 5 ft 4 in to 6 ft 2 in. The step-through space above the battery box makes it easy to get on, and the 264 lb load rating covers most adults with a pack. If you are much taller than 6 ft 2 in the bars will feel close, so sit on one before ordering.

On pavement and packed gravel it rolls smoothly and the fat casing soaks up a curb, and the mid drive pulls away cleanly from a stop. On loose sand the front can wash if you are heavy on the bars, so shift your weight back. The mechanical discs are adequate rather than sharp, and they want a firm pull in the wet.

• Pavement, bike paths and packed gravel
• Campgrounds and beach towns
• A second bike for a household
• Not for tight singletrack or stairs

What's in the Box

Before the first ride: fit the front wheel and torque the axle, set the bars square to the fork, check the derailleur shifts through all seven gears, bed the cable discs in with ten firm stops and charge the pack. Budget 30 to 45 minutes, and check the brake cables for stretch after the first ten miles.

Color and Finish

Black covers the frame, battery box, fenders, rack and rims, with white lettering on the two frame plates and a copper-brown saddle and grips on the lighter build. The motor cover carries the colour ring, so the only real colour on the bike comes from that and from the reflectors on the pedals.

Touch-up paint in gloss black is available on request. The wear points are the battery box where a shoe rubs it, the frame plate edges and the rear rack where straps sit.

Battery Care and Maintenance

Charge the pack between 20 and 90 percent for daily use and take it to full about once a month. The battery lives in the frame on this bike rather than lifting out, so charge it where the bike is parked and keep that spot above freezing. Store it around half charge if the bike will sit for a month or more.

Check tire pressure before every ride at 15 psi on pavement and 8 on sand, and check the spokes and axle nuts after the first 50 miles. The cable discs need the barrel adjuster turned as the pads wear, and the pads are a five-minute swap. Keep the chain clean and oiled so the seven gears shift, and wipe the fork legs after a wet ride.
