A Moped Frame a Removable Pack and Hydraulics at Both EndsGold Rims Against the Late Sunsets

An aluminum moped frame carrying a 1500W peak hub motor rated at 1000W, 80 Nm of torque and a 48V 25Ah pack worth 1200Wh that lifts out of the down tube to charge. Twenty-inch 4.0 knobby tires on gold rims, 80 mm of fork travel over a 180 mm rear coil shock, dual-piston hydraulic discs and a Shimano 7-speed drivetrain. An Angel Eye headlamp, an LCD dash and five assist levels finish a bike built for fire roads, farm tracks and the ride to work.

The silhouette is the selling point: a straight top tube carrying a long bench, a down tube wide enough to swallow a 25Ah pack, a gold rim at each end and a cargo basket bolted to the head tube. It reads as a small motorcycle rather than a bicycle, and the matte black finish with gold decals keeps that impression at close range instead of falling apart under a streetlight. The design reads well in person.

What holds it together is a 6061-T6 aluminum frame, hydroformed and triple butted, which is the reason the whole thing weighs what a bicycle can still carry up a flight of stairs. The moped shape also puts the battery low and central, so the bike steers like something much lighter than its footprint suggests.

Moped Frame and Gold 20 Inch Wheels

The frame is a moped shape in 6061-T6 aluminum, hydroformed and triple butted, with a long bench over the rear wheel and a battery box in the down tube. Up front there is a cargo basket bolted to the head tube and the Angel Eye headlamp.

The wheels are spoked, not cast, with gold anodized rims laced to black hubs. Spokes are the right call on a bike this heavy: a bent rim can be trued at home with a spoke key, where a cast wheel has to be replaced.

Suspension is at both ends. Up front is a 20-inch shoulder shock with 80 mm of travel, and behind it a coil unit rated to 850 lb with 180 mm of travel, so the back end absorbs a washboard track instead of passing it up your spine.

• Frame: 6061-T6 aluminum, moped shape
• Battery: 48V 25Ah, removable down tube
• Wheels: spoked, 20 in gold rim
• Fork: shoulder shock, 80 mm travel
• Rear: coil shock, 180 mm travel
• Brakes: dual-piston hydraulic, 180 mm

Fitted as shipped: front and rear fenders, the head tube cargo basket, the Angel Eye headlamp, a rear LED, the LCD dash and a kickstand. The bars carry the thumb throttle, the five-level assist switch and the brake levers with their motor cut-offs.

1500W Peak and the 1200Wh Pack

The motor is a 48V brushless rear hub rated at 1000W continuous and 1500W peak, with 80 Nm of torque and a listed 35 degree climb, fed by a 28A controller. Write both numbers down if you are comparing bikes: 1000W is what the motor will hold on a long grade, 1500W is the short burst that gets you moving. A Shimano 7-speed derailleur and a 46T crank sit behind it so you can add leg power on the same climb.

The pack is 48V 25Ah, 1200Wh in 18650 cells, and it lifts out of the down tube, so you can carry it to an outlet instead of parking the bike beside one. It charges in 3.5 to 8 hours on the supplied 48V 3A unit, the long end being a full charge from empty through the bike's own port. The other option is direct charging with the pack still fitted, which is what most owners do overnight.

Range is quoted two ways and both are worth knowing. Throttle-only, with no pedalling at all, the figure is 50 plus miles; in Class 1 pedal assist, where the motor tops out around 20 mph and you are turning the cranks, it stretches to 87 miles. Cold weather, a heavy rider, soft sand and a hill all pull that down, so plan a loop on the lower number and treat the higher one as a best case.

Who It Fits and How It Rides

The bench is fixed rather than on a post, which is the one thing to check before ordering: it suits roughly 5 ft 4 in to 6 ft 2 in and it puts you lower and further back than a saddle bike does. Riders outside that band should sit on one first.

On gravel and packed dirt it tracks straight and the 80 mm fork keeps the bars from kicking, while the rear coil takes the chatter out of a rutted track. On pavement the knobbys hum and the steering is deliberate rather than quick, which is the trade for the tire volume.

• Fire roads, farm tracks and gravel
• Beach towns and campgrounds
• Commuting where a moped shape is legal
• Not for tight singletrack or stairs

What's in the Box

Before the first ride: fit the front wheel and torque both axles, 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. Budget 40 to 60 minutes, most of it on the front wheel and the basket.

Color and Finish

Black covers the frame, fork lowers, fenders, basket and bench, and the gold is held to the rims, the GT20 decals on the down tube and a stripe along the battery box.

Touch-up paint in matte black is available on request. The wear points are the bench edges, the basket where it takes curb knocks and the anodized rim faces if you ride through grit.

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. Because the pack lifts out, the simplest routine is to carry it indoors and charge it on a bench at room temperature, then refit it before the ride. Store it around half charge if the bike will sit for a month or more.

Check tire pressure before every ride at 15 to 20 psi on pavement and 8 to 12 psi on sand, and check the spokes for tension after the first 50 miles, because a new wheel bed in. Check the hydraulic pads monthly and the rotor bolts for tightness, keep the chain clean so the seven speeds shift, and wipe the gold rims after a wet ride so road salt does not pit the anodizing.
