Two Packs Sixty Volts and Travel That Really Goes Both WaysSixty Volts You Can Feel Underfoot

A moped-style dirt bike with a 2000W hub, a 60V 40Ah pack worth 2400Wh split across two batteries, and 20 x 4.0 knobby tires on gold rims. An 80 mm fork over a 180 mm rear coil rated to 850 lb, hydraulic discs at both ends, a seven-speed drivetrain and a full lighting set with turn signals and twin tail lamps. It weighs 94.6 lb, carries 330 lb, and the full light set with turn signals makes it usable at dusk in a way an unlit dirt bike is not.

The frame is a black moped shape with the battery box filling the space under the top tube and a long bench running back over the rear wheel to a flat rack. Gold is restricted to the rims and the GT20 decal on the down tube, and the fork is a straight-leg unit with a round headlamp on the crown. It reads as a small motorcycle from the side and that is the intent.

Two batteries are what make the 2400Wh figure possible. They sit in the frame rather than on a rack, which keeps the weight between the wheels, and the bike is heavy because of it: 94.6 lb before a rider. The upside is range, and the downside is that this is not a bike you lift onto a hook in a garage without help.

Moped Frame and Gold Rims

The frame is a black moped shape with a boxed section under the top tube that holds the batteries, a bench that runs back over the rear wheel and a flat rack behind it. Gold appears only on the rims and in the GT20 decal, and the fork is a straight-leg unit with a round headlamp and a pair of turn signals mounted on the crown.

The wheels are 20 x 4.0 knobbys on spoked rims with gold anodized hoops. Spokes can be trued with a key after a hard landing, and the wide casing is what makes a bike this heavy float on sand instead of digging in. Run them at 15 psi on pavement and 8 on sand.

Suspension is 80 mm of fork travel up front and a coil unit at the rear rated to 850 lb with 180 mm of travel, which is more than most bikes in this class offer and is the reason the bike stays settled on a rutted track. Brakes are hydraulic calipers on both rotors, with the levers set for a two-finger pull.

• Frame: black moped shape
• Battery: 60V 40Ah, two packs in the frame
• Wheels: 20 in spoked, gold rims
• Fork: 80 mm travel
• Rear: coil, 180 mm travel, 850 lb
• Brakes: hydraulic disc, front and rear

Fitted as shipped: the round headlamp, front and rear turn signals, twin tail lamps, front and rear fenders, a flat rear rack, a kickstand and the pedals. The bars carry the throttle, the assist switch and the brake levers, and the frame carries the charge port for both packs.

2000W and 2400Wh of Battery

The motor is a 2000W hub on a 60V system, which is a step up from the 48V bikes in this group: more voltage means less current for the same power, so the wiring and the controller run cooler. It drives the rear wheel through a seven-speed derailleur, so you can gear down and let the motor work where it is efficient.

The pack is 60V 40Ah, 2400Wh, split across two batteries in the frame. That is the largest capacity here, and the listed range is still 20 to 37 miles, which tells you what 2000W does to a battery when you use it. Ride at half throttle and you will see the top of that range; hold it open on sand and you will see the bottom.

Charging two packs takes planning rather than a quick top-up. Treat it as an overnight job, charge where the bike is stored, and keep the port dry. The 60V architecture also means the charger is not interchangeable with a 48V unit, so do not lose it.

Who It Fits and How It Rides

The bench is long and low and the bars are high, so it suits riders from about 5 ft 5 in to 6 ft 3 in. The 330 lb load rating covers a heavy adult with a pack, and the 850 lb rear spring is what makes that rating real rather than optimistic. At 94.6 lb it is a two-person lift onto a truck bed.

On dirt and gravel the travel and the fat casing do the work, and the turn signals and tail lamps make it usable at dusk where an unlit dirt bike would not be. On pavement it is heavy and slow to steer, and the range drops quickly at speed. Check what your state allows before riding it on a public road.

• Dirt tracks and fire roads
• Campgrounds and private ground
• Dusk riding with the full light set
• Not for bike lanes or a roof rack

What's in the Box

Before the first ride: fit the front wheel and torque the axle, check both battery connectors are seated, set the rear spring preload for your weight, bed the hydraulic brakes in with ten firm stops and charge both packs. Budget 45 to 70 minutes, and check the spokes and axle nuts after the first ten miles.

Color and Finish

Black covers the frame, battery box, fenders, bench, rack and fork, and the gold is in the rim hoops and the GT20 lettering. The brake calipers are anodized red, which is the only other colour on the bike, and the finish is satin rather than gloss so trail dust does not show.

Touch-up paint in satin black is available on request. The wear points are the battery box where a boot rubs it, the rack edges and the anodized rim faces if you ride through grit.

Battery Care and Maintenance

Two packs mean two charging routines. Charge each between 20 and 90 percent for daily use, take them to full about once a month to balance the cells, and never charge them below freezing. If the bike will sit for a month, leave both around half charge and top them up every few weeks.

Check tire pressure before every ride at 15 psi on pavement and 8 on sand, and check the spokes and both axle nuts after the first 50 miles. Hydraulic brakes need the pads checked monthly and the lever feel watched for sponginess. Keep the chain oiled so the seven gears shift, and wipe the fork stanchions after a wet ride.
