Hydraulic Inverted Fork DNM Rear Shock and Snow Tires 20x4.5Soft Tail Days and Wide Tire Nights

A soft tail fat tire electric bike with a 1500W MXUS hub in the rear wheel, a 52V 25Ah pack worth 1300Wh in the frame, and INNOVA 20 x 4.5 all-terrain tires on hollow snow rims. A hydraulic inverted fork up front and a DNM shock under the seat, SIMAERS hydraulic disc brakes and a Shimano seven-speed drivetrain. Listed at 25 to 31 miles per charge and 34 mph, with an LCD, three ride modes and a helmet, lock, phone holder and mirrors in the kit.

The soft tail is the reason this frame exists: an aluminum alloy chassis with a hydraulic inverted fork in front and a DNM shock under the extended seat, so roots and broken pavement get filtered before they reach the rider. The paint is a triple-layer job over the alloy, the battery sits in the frame where the mass wants to be, and the bench seat lets the rider move for a turn instead of standing on the pegs the whole way.

The honest trade is speed and charge time. A listed 34 mph from a 1500W hub is quick enough that this bike wants a helmet every ride and a look at your local rules before it mixes with traffic, and the pack takes about eight hours on the charger. Three ride modes, pedal assist, electric and plain pedaling, keep the range story flexible.

Soft Tail and Stopping Power

The frame is a 20-inch aluminum alloy soft tail, welded so the rear end can move instead of passing every root straight to the saddle. Triple-layer paint covers the alloy, and the battery lives in the frame where the mass sits low and centered.

Up front is a hydraulic inverted fork with the stanchions up top where they stay cleaner, and out back a DNM shock sits under the extended seat. Between them the bike carries its rider over washboard and curb cuts rather than through them.

Braking is SIMAERS hydraulic discs at both wheels, with a rotor on each hub and a lever feel that stays firm as the pads wear. Hydraulic lines self-adjust at the caliper, so the lever does not creep in between services, and one finger at each end parks it on a slope.

• Frame: aluminum alloy soft tail, triple-layer paint
• Front fork: hydraulic inverted, aluminum
• Rear: DNM shock under the seat
• Brakes: SIMAERS hydraulic disc, front and rear
• Tires: INNOVA 20 x 4.5 all-terrain
• Drivetrain: 7-speed Shimano freewheel

Fitted as shipped: the LED headlight with brake, running and rear turn lights, a horn, the LCD on the bars, the extended bench seat and platform pedals. The 750mm Big Hawk handlebar carries the throttle, the Shimano shifter and the brake levers.

1500W MXUS Hub and the 52V Pack

The motor is a 1500W MXUS hub in the rear wheel on a 52V system, and the drivetrain behind it is a Shimano seven-speed freewheel with a 42T crankset. The hub pulls from a stop clean and holds a trail pace, while the pedals stay a real fallback for the last mile when the pack runs low. The wide gear range turns a loaded climb into a shift rather than a walk. MXUS hubs run quiet and ask for nothing beyond a tight axle nut.

The pack is 52V 25Ah, worth 1300Wh, built from EVE 21700 cells and carried in the frame. We quote 25 to 31 miles per charge, the conservative span from the source specifications; its headline line claims 28 to 34 miles, so treat 25 to 31 as the number a plan holds to in cold weather or on hills. Charging from empty takes about eight hours on the included charger.

The LCD shows speed, battery level and the assist setting at a glance, driven by weather-sealed DMHC electronics with a 42A controller. Three ride modes, pedal assist, electric and plain pedaling, switch from the bars, and the throttle sits under the right hand for the moments when pedaling through soft ground would only spin the wheel.

Snow, Sand and City Streets

This bike is built for the days when the pavement runs out: snow, sand, loose gravel and the kind of trail that punishes a street tire. The soft tail and the 4.5-inch casings do the work, and the bench seat keeps the rider moving when the line gets awkward.

The INNOVA all-terrain tread on double-layer hollow snow rims is the other half of the story: the wide contact patch floats over soft ground, and the hollow rim design takes cold-weather abuse better than a plain alloy rim.

• Snow, sand and loose trails
• City streets and daily loops
• Riders who want a soft-tail ride
• Forest roads and doubletrack
• Not for stairs or a roof rack

What's in the Box

Partially assembled on arrival: fit the front wheel, the handlebar and the pedals, then torque-check every bolt and charge the pack before the first ride. Budget 30 to 45 minutes, then recheck the axle nuts and the bars after the first ten miles.

Color and Finish

One finish: black over the triple-layer paint, with the DITON panel on the battery cover and the bull-head logo on the seat. The fork lowers, the rims, the fenders and the bars are all dark, so the frame graphics and the red accents on the fork decals do the talking.

The wear points are the fork stanchions, which want a wipe after a wet ride, the chainstay where the chain slaps, and the seat corners where a bag rubs.

Battery Care and Maintenance

One full charge before the first ride, then keep the 1300Wh pack near the middle of its band for daily use and take it to full now and then so the cells balance. Charge indoors at room temperature, keep the charge port covered between sessions, and store the pack around half charge if the bike will sit for a month.

Each ride starts with a tire pressure check and a squeeze of both brake levers. Hydraulic pads want a look monthly, the seven-speed chain wants a wipe and a drop of lube, and the DNM shock wants its sag set to the rider now and then. Keep the axle nuts tight, wipe the frame with a damp cloth after wet rides, and never aim a pressure washer at the connectors.
