HKM-9261267 750W Electric Fat Tire Mountain Bike, 48V 15Ah Battery, 7-Speed Shimano Drivetrain, 26 x 4.0 in Chaoyang Tires
HKM-9261267
750 W 25 mph Electric Fat Tire Mountain Bike
The HKM-9261267 is built around a 6061 aluminum alloy hardtail frame with a slack head angle and long wheelbase that keeps the bike stable at speed on descents. The frame is rated for a combined rider-and-cargo load of 300 lb, enough for most adult riders plus a small backpack or handlebar bag.
Key Features
8 details that make the HKM-9261267 a dependable ride.
750 W Brushless Rear Hub Motor
A 750 W brushless motor (1200 W peak) is laced into the rear wheel hub. No chain or belt connects the motor to the ground, so drive losses stay low and maintenance is minimal. Peak output handles a 20 degree slope with a solo rider.
48 V 15 Ah Lithium Pack (720 Wh)
The removable pack stores 720 Wh of energy -- enough for multi-day touring between charges on moderate assist. It lifts out with a key for indoor charging. A full recharge takes about 5-6 hours on the supplied 2 A charger.
Lockable Air Suspension Fork (100 Mm Travel)
An air/oil suspension fork with 100 mm of travel and mechanical lockout smooths out rocks, roots, and potholes when unlocked. Lock it out for efficient pedaling on smooth pavement and climbs.
Hydraulic Disc Brakes Front and Rear
Sealed hydraulic lines actuate both calipers. Lever effort stays light when rotors get hot, and there are no cables to stretch. Power-off brake levers cut motor drive instantly when either lever is pulled.
7-Speed Shimano Derailleur Drivetrain
A 7-Speed Shimano derailleur with index shifter gives usable pedaling cadence from walking pace up to cruising speed. The wide gear range lets you add human power to extend range or climb under your own effort.
26 x 4.0 in Chaoyang All-Terrain Fat Tires
The wide casing spreads weight over a large contact patch at low pressure (12-18 psi). Chaoyang's directional tread pattern clears mud well and grips gravel, dirt, sand, and packed snow where narrow tires would slide.
Front and Rear Fenders Included
Full-coverage fenders keep spray and grit off your clothes and drivetrain components. They bolt directly to the fork and rear stays using pre-drilled mounting points, and can be removed in dry conditions if preferred.
Rear Cargo Rack Ready
The frame includes integrated rack mounts above the rear axle. A compatible rack (sold separately or included depending on configuration) supports panniers, a trunk bag, or a child seat within the 300 lb load limit.
Overview
Built for the ride ahead.
The HKM-9261267 is built around a 6061 aluminum alloy hardtail frame with a slack head angle and long wheelbase that keeps the bike stable at speed on descents. The frame is rated for a combined rider-and-cargo load of 300 lb, enough for most adult riders plus a small backpack or handlebar bag. A 750 W brushless rear hub motor with a 1200 W peak rating provides strong acceleration from a stop and confident climbing on grades up to 20 degrees. The motor drives through the rear hub so there is no chain between motor and ground -- drive losses stay low and maintenance is limited to keeping axle nuts torqued. The 48 V 15 Ah lithium pack stores roughly 720 Wh of energy. Throttle-only on flat pavement returns around 25-35 mi. Moderate pedal-assist on the same surface stretches that to 45-55 mi.
Removable Pack, Charge Anywhere
The removable pack means you can charge indoors and leave the HKM-9261267 where it stands.
It belongs in a real home and a real routine, not only a showroom. The details you never name are the ones you end up trusting the most. The HKM-9261267 pairs a 750 W brushless rear hub motor, 1200 W peak, 48 V 15 Ah lithium-ion (720 Wh), removable and lockable, a range of 35-60 mi (56-97 km), varies with terrain, rider weight, and assist level, so it is built for real-world rides rather than showroom specs.
Full Specifications
Measurements are shown in US customary units first, with metric equivalents in parentheses.
Battery, Range, and Charging
Up to 35-60 mi (56-97 km) per charge.
The 48 V 15 Ah pack stores 720 Wh of energy. Most commuter e-bikes ship with 400-500 Wh, so this pack runs 40-80 percent above average for its class. That extra capacity is what lets you ride farther between charges or carry extra gear without range anxiety. Real-world range depends primarily on how much you pedal, rider weight, tire pressure, and terrain. Throttle-only on flat pavement at moderate speed lands in the 25-35 mi band. Moderate pedal-assist on the same surface regularly returns 45-55 mi. Aggressive pedaling at low assist on level ground has been measured at 60 mi from a full charge. Cold weather below 40 F (4 C) temporarily reduces available capacity by 10-20 percent; it returns once the pack warms up.
Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Run tire pressure at 12-15 psi for off-road grip; increase to 18-22 psi for paved commutes to reduce rolling resistance.
Rinse the frame, rims, and drivetrain with fresh water after riding on muddy trails or salted roads.
Check that both axle nuts and stem bolts are torqued before the first ride of each week.
Wipe and re-lubricate the chain every 100-150 mi, or after any ride through standing water or dusty conditions.
Inspect brake pad thickness monthly. Hydraulic pads wear silently until gone; 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.

Why Choose the HKM-9261267
6 reasons it earns its place.
Fat Tire All-Terrain Capability
The 26 x 4.0 in Chaoyang tires run at low pressure to create a large contact patch that floats over sand, grips loose gravel, and absorbs bumps that would jar a narrow tire.
Hardtail Efficiency with Front Cushion
The rigid rear end transfers every watt of pedaling power into forward motion, while the lockable 100 mm travel fork takes the edge off rocks, roots, and potholes.
Two Ways to Ride
Use the thumb throttle for immediate acceleration from stops, or shift through the 7-Speed Shimano gears and pedal to extend range. Most owners mix both modes.
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 and a quiet ride.
Above-Average Battery Capacity
At 720 Wh, the 48 V 15 Ah pack holds more energy than most bikes in this class, translating into longer rides and fewer charge stops per week.
Daily-Ready Build
Fenders keep road spray off your clothes, the rear rack accepts panniers or a trunk bag, and sealed connectors resist moisture from morning dew or puddles.
Every Component Chosen for Real-World Use
Every component of the HKM-9261267 is chosen for real-world use.

Frequently Asked Questions
Quick answers about the HKM-9261267.
How much assembly is required out of the box?
The bike ships approximately 85 percent assembled. Remaining steps are fitting the front wheel, straightening and bolting the handlebar, installing the pedals and saddle, mounting the fenders, and checking brake alignment. Budget 30-45 minutes with the supplied tools.
What kind of terrain can this bike handle?
The 26 x 4.0 in Chaoyang fat tires make this bike capable on gravel, dirt trails, packed sand, light snow, and grass. The hardtail design with front suspension handles fire roads and rail-trails well; it is not intended for extreme downhill riding.
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 25-35 mi. Moderate pedal-assist on mixed terrain regularly returns 45-55 mi. Heavier riders, headwinds, hills, and low tire pressure all reduce range.
Is a license or registration required?
Rules vary by state and locality. A 750 W nominal motor with 25 mph top speed may place this bike outside standard Class 1/2/3 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 5-6 hours from fully empty with the supplied 2 A charger. Partial top-ups take proportionally less time; there is no need to run the pack down first.
Can I pedal it if the battery runs out?
Yes. The 7-Speed Shimano drivetrain works independently of the motor. The bike weighs approximately 62 lb, so pedaling home unassisted is slow but possible on flat ground.
Should I lock out the front suspension on pavement?
Yes. Locking the fork on smooth surfaces eliminates bob from pedaling forces, making your effort go forward instead of being absorbed by the suspension. Unlock it as soon as the surface gets rough.
Is the battery removable for indoor charging?
Yes. It unlocks with the supplied key and lifts out of the down tube. You can also charge it in place through the frame-side charge port.
Quick Troubleshooting
Common issues and what to check first.
The motor does not engage when I press the throttle.
Confirm the LCD is on and shows charge, the battery is locked in place, and both brake levers are fully released. If the display shows an error code, note it and contact support.
Range dropped noticeably compared with when it was new.
First check tire pressure; a soft tire is the most common cause. Then consider temperature. If range is down more than 30 percent year-round after many cycles, the pack may be nearing end of life.
The brakes feel spongy at the lever.
Sponginess 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.
The 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 in multiple gears.
The front fork makes noise over small bumps.
Check that the lockout lever is fully disengaged when riding off-road, and that the fork stanchions show no scoring or oil leakage. A dry squeak can often be fixed with a dab of fork grease on the wiper seals.
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 it and contact support with the exact code and conditions.

Pre-Ride Safety Checklist
Run through these before every ride.
Check tire pressure: 12-15 psi for off-road, 18-22 psi for pavement.
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 LCD shows expected charge.
Spin both wheels and check that rims run true and nothing rubs brake pads or frame.
Verify quick-release levers and axle nuts are tight; check headset for play with front brake applied.
Test the thumb throttle at walking pace in a clear area before riding in traffic.
Switch on headlight and tail-light if riding near dusk; wear a helmet rated for these speeds.
Toggle the fork lockout lever to confirm it moves freely between locked and open positions.

Important Safety Notes
Read before the first ride.
This 750 W bike is rated at 25 mph. Read the manual first and practise throttle and braking in an open, traffic-free area. Leave extra room for braking, since stopping distance grows fast with speed and load. Wear a helmet every ride. Do not exceed the 300 lb (136 kg) load limit, including rider, cargo, and rack load. Confirm local law before riding on public roads. Bed the brakes in with 10-15 progressive stops over the first rides. Never ride through water deep enough to reach the motor or battery. Charge only with the supplied charger, indoors and attended. Never open, puncture, or modify the pack. Slow down substantially on gravel, wet surfaces, and steep descents.
