Overview
The HKM-6760147 is built on a standard 26-inch aluminum hardtail frame scaled for adult riders. The larger wheel diameter rolls more efficiently over obstacles and maintains momentum better than smaller wheels on rough terrain. The frame is rated for a combined rider-and-cargo load of 330 lb, which supports most adult riders plus gear or light cargo on the included solid rear rack.
A 1000 W brushless rear hub motor with a 1500 W peak rating provides strong acceleration from stops and confident climbing on moderate hills. The motor drives directly through the rear wheel hub with no intervening chain or belt, keeping drive losses low and maintenance straightforward. A 48 V 15 Ah lithium pack stores roughly 720 Wh of energy - above average for this class - giving meaningful range even when carrying extra weight.
Real-world range covers a wide band depending on riding mode and conditions. Throttle-only on flat pavement returns around 30-40 mi. Moderate pedal-assist on mixed terrain stretches that to 42-52 mi. Aggressive pedaling at low assist on level ground can reach up to 60 mi from a full charge. Cold weather below 40 F (4 C) reduces available capacity by 10-20 percent.
The 26 x 4.0 in fat tires are the defining feature of this bike. Run at 10-15 psi they provide flotation on soft surfaces, grip on loose terrain, and natural cushioning that complements the lockable hydraulic front fork. Full-coverage fenders keep road spray off the rider, and the solid rear rack supports roughly 50 lb of cargo for commuting or errands.
Key Features
1000 W Brushless Rear Hub Motor
A 1000 W brushless motor (1500 W peak) is laced into the rear wheel hub. Direct drive means no chain or belt between motor and ground surface, so power transfer stays efficient and maintenance is limited to keeping axle nuts torqued. Peak output handles grades up to 25 degrees with a solo rider.
48 V 15 Ah Lithium Pack (720 Wh)
The removable battery sits in a carrier on the down tube and lifts out with a key for indoor charging. At 720 Wh, this pack carries above-average energy for a 26-inch fat-tire e-bike, supporting longer rides and cargo-heavy commutes. A full recharge takes about 6-7 hours.
Lockable Hydraulic Front Fork (Hardtail)
A hydraulic suspension fork with mechanical lockout smooths out broken pavement, roots, and trail obstacles when unlocked. Lock it out on smooth roads for efficient pedaling without bob. Adjustable preload matches the fork to rider weight.
Hydraulic Disc Brakes, Front and Rear
Sealed hydraulic lines actuate both calipers. Lever effort stays light and predictable when rotors heat up during repeated stops, and there are no cables to stretch or corrode. Power-off brake levers cut motor drive instantly when either lever is pulled.
7-Speed Shimano Derailleur Drivetrain
A 7-Speed drivetrain provides usable pedaling cadence from walking pace up to cruising speed. Contribute human power to extend range, climb efficiently, or get light exercise while the motor supplies the bulk of the effort.
26 x 4.0 in All-Terrain Fat Tires
The larger 26-inch wheel diameter rolls more efficiently over obstacles than smaller wheels. Run at 10-15 psi, the wide casing provides traction on sand, snow, gravel, and wet pavement while acting as natural suspension for small bumps.
Round LED Headlight and Multi-Mode Rear Light
A round LED headlight runs off the main battery with no separate batteries needed. A multi-mode rear light includes brake-activated illumination whenever either lever is pulled plus running light mode for constant visibility from behind.
Solid Rear Rack With Full-Coverage Fenders
A welded steel rear rack supports roughly 50 lb of cargo for commuting, grocery runs, or gear hauling. Full-coverage front and rear fenders keep road spray, mud, and grit off the rider and the bike components.

Battery, Range, and Charging
The 48 V 15 Ah pack stores 720 Wh of energy. That capacity sits above the typical range for 26-inch fat-tire e-bikes, providing real headroom for daily commuting at moderate speeds and enough reserve for cargo-heavy trips without frequent recharging.
Real-world range depends primarily on how much you pedal, total rider and cargo weight, tire pressure, and terrain. Throttle-only on flat pavement lands in the 30-40 mi band. Moderate pedal-assist on mixed surfaces returns 42-52 mi. Aggressive pedaling at low assist can reach up to 60 mi from a full charge. Cold weather below 40 F (4 C) temporarily reduces available capacity by 10-20 percent.
Tip: Store the pack between 30 and 70 percent charge if unused for more than a month, and top it up every 4-6 weeks. Charging indoors at room temperature extends pack life.
The battery unlocks with the supplied key and lifts out of its down-tube carrier for indoor charging. Two keys are included. Charging with the pack installed works equally well through the accessible frame-side charge port.
Daily Use & Care
- Check tire pressure before each ride: 12-15 psi for pavement, 10-12 psi for trails or soft surfaces.
- Rinse the frame, rims, fenders, and drivetrain with fresh water after riding on salted roads or through mud.
- Confirm both axle nuts and stem bolts are torqued before the first ride each week. High-torque motors loosen fasteners faster.
- Wipe and lubricate the chain every 100-150 mi, or after any ride through water or dusty conditions.
- Inspect brake pad thickness monthly. Hydraulic pads wear silently; replace when friction material is under 1 mm.
- Charge indoors at room temperature. Unplug once the indicator turns green rather than leaving it connected for days.
- Keep display and charge port covers closed when parked outside so moisture stays out of connectors.

Frequently Asked Questions
How much assembly is required out of the box?+
The bike ships approximately 85 percent assembled. Remaining steps: fit the front wheel, straighten and bolt the handlebar, install pedals and saddle, check brake alignment, and attach any loose fender/rack hardware. Budget 30-45 minutes with supplied tools.
What is the actual range I should plan for?+
Plan for 35-60 mi depending on how much you pedal. Throttle-only at higher speeds lands closer to 30-40 mi. Moderate pedal-assist regularly returns 42-52 mi. Heavier loads, hills, headwinds, and low tire pressure all reduce range.
How much cargo can the rear rack carry?+
The solid rear rack is rated for roughly 50 lb (23 kg) of distributed cargo. This is adequate for panniers, a backpack, groceries, or a small child seat (check seat manufacturer specs). Always confirm total weight stays within the 330 lb combined limit.
Is a license or registration required?+
Rules vary by state. A 1000 W nominal motor with 1500 W peak output and 28 mph top speed may place this vehicle outside standard Class 1-3 e-bike limits in some jurisdictions. Check your state DMV and local ordinances before riding on public roads.
How long does the battery take to charge?+
About 6-7 hours from fully empty with the supplied 2 A charger. Partial top-ups take less time.
Can I pedal it if the battery runs out?+
Yes. The 7-Speed Shimano drivetrain works independently of the motor. At approximately 77 lb with battery, pedaling unassisted is slower but entirely possible on flat ground.
Will the brakes handle the speed and potential cargo load?+
Hydraulic disc brakes front and rear are appropriate for a 28 mph bike of this weight. Bed the pads during the first few rides with 10-15 progressive stops. Brake earlier than usual when carrying cargo.
Are the fenders effective in wet weather?+
The full-coverage front and rear fenders are sized for 26 x 4.0 in tires and keep most road spray off the rider and bike components. They are particularly useful for rainy commutes.

Why Choose the HKM-6760147
26-Inch Wheels for Efficient Rolling
The larger 26-inch wheel diameter rolls more smoothly over obstacles and maintains momentum better than smaller wheels on rough terrain. Combined with fat tires, this size offers a compromise between the maneuverability of 20-inch wheels and the cruising efficiency of 29ers.
Fat Tires for True All-Terrain Capability
The 26 x 4.0 in fat tires at 10-15 psi float over soft surfaces and grip loose terrain where narrower tires would slide. Sand, snow, packed dirt, wet pavement, and gravel all become rideable surfaces that a conventional tire cannot handle safely.
Two Ways to Ride
Twist the throttle for immediate acceleration, or shift through the 7-Speed Shimano cassette and pedal. Most owners mix both modes - throttle from stops, pedals to extend range, motor for hills.
Direct-Drive Hub Motor Simplicity
The motor lives in the rear hub with no mid-drive gearbox or extra chain to service. Fewer moving parts means less maintenance, lower noise, and a simpler ownership experience.
Rear Rack + Fenders for Practical Commuting
The included solid rear rack and full-coverage fenders transform this bike from a recreational toy into a practical commuting tool. Carry groceries, a backpack, or panniers while staying clean and dry in wet weather.
Built for Daily Riding in Any Weather
Sealed electrical connectors, a lockable removable battery system, hydraulic brake lines that resist corrosion, and full fenders all support daily commuting use regardless of weather conditions.

Pre-Ride Safety Checklist
- Check tire pressure: 12-15 psi for pavement, 10-12 psi for trails or soft surfaces.
- Squeeze both brake levers. They should firm up well before reaching the grip, with no sponginess.
- Confirm the battery is seated and locked, and the display shows expected state of charge.
- Spin both wheels and check that rims run true and nothing rubs brake pads or fenders.
- Verify quick-release levers and axle nuts are tight, and headset has no play when rocking the bike with front brake applied.
- Test the throttle at walking pace in a clear area before riding in traffic.
- Switch on the headlight and rear light if riding near dusk, and wear a helmet rated for the speeds this bike reaches.
Quick Troubleshooting
The motor does not engage when I twist the throttle.+
Confirm the display is on and shows charge, the battery is locked in place, and both brake levers are fully released - brake cut-off sensors disable the motor while a lever is pulled. If an error code appears, note it and contact support.
Range dropped noticeably compared with when it was new.+
First check tire pressure; a soft tire on pavement is the most common cause. Cold weather also temporarily reduces capacity. If range is down more than 30 percent year-round after many cycles, the pack may be approaching end of service life.
The brakes feel spongy at the lever.+
Sponginess in a hydraulic system usually means air in the line or a fluid leak. Stop riding and have the system bled and inspected. Do not continue riding on compromised brakes.
The chain skips under hard pedaling.+
Derailleur indexing is likely out of adjustment, or the chain and cassette are worn. Adjust the barrel adjuster a quarter turn at a time. Replace chain and cassette together if skipping persists only in smaller cogs.
The front fork rattles over bumps or feels stiff.+
Check that quick-release levers are fully closed and the wheel is seated. If rattling persists, inspect stanchions for scoring. If stiff, confirm the fork has not been locked out accidentally.
The display shows an error code and the bike will not move.+
Power off, wait 30 seconds, and switch back on. If the code returns, note the exact code and conditions, then contact support.

Important Safety Notes
This is a high-output electric bicycle capable of 28 mph. Read the manual fully before the first ride and practice throttle control in an open, traffic-free area until the response feels predictable.
- Wear a helmet on every ride. At 28 mph a certified bicycle helmet is the minimum.
- Do not exceed the 330 lb (150 kg) load capacity, which includes the rider, any cargo, and accessories.
- Check local law before riding on public roads or paths. A 1000 W motor may place this vehicle outside standard e-bike classifications in your area.
- Bed in the brake pads with 10-15 progressive stops during the first few rides before riding at full speed or with heavy cargo.
- Do not ride through water deep enough to reach the hub motor or battery compartment.
- Charge only with the supplied charger, indoors, at room temperature, and on a non-flammable surface.
- Do not attempt to open, puncture, or modify the battery pack. Damaged lithium packs can vent and ignite.
- Reduce speed substantially on gravel, wet surfaces, and downhill grades; fat tires add grip but do not eliminate skid risk.
