HKM-3586643 26 in x 4.0 Fat Tire Full Suspension Electric Mountain Bike, 2000 W Dual Hub Motor, 48 V 20 Ah Removable Battery
HKM-3586643
2000 W Fat Tire Full Suspension Electric Mountain Bike
The HKM-3586643 puts two 1000 W brushless hub motors - one in each wheel - behind a 48 V 20 Ah (~960 Wh) removable battery. The dual-motor layout delivers true all-wheel-drive traction, so the bike keeps moving on loose gravel, wet grass, packed snow, and soft sand where a single-motor e-bike would spin a wheel.
Key Features
8 details that make the HKM-3586643 a dependable ride.
Dual 1000 W Hub Motors
Two 1000 W brushless geared hub motors deliver combined peak output of 2000 W. The front motor handles initial acceleration and light traction duty; the rear motor adds the bulk of the climbing torque. A handlebar-mounted switch lets the rider choose front-only, rear-only, or both motors on the fly - useful when range matters on a long ride.
Removable 48 V 20 Ah Battery
A 48 V 20 Ah (~960 Wh) lithium pack slides up out of the down tube for indoor charging. The integrated location keeps the frame silhouette clean and lowers the center of gravity for better handling under hard braking. A keyed cradle lock prevents the pack from being removed or powered on without the key.
Air-Sprung Front Fork
The adjustable air-sprung suspension fork takes the bigger hits before they reach the handlebars. A lockout lever on the crown stiffens the fork for road sections so energy is not wasted on pedal-induced bob.
Rear Shock Absorber
A frame-mounted rear shock works with the front fork to deliver full four-bar suspension. The rear wheel stays planted over roots and ripples instead of bouncing, which preserves traction on loose climbs and rough descents.
Hydraulic Disc Brakes
Front and rear hydraulic disc brakes deliver strong, modulated stopping power in wet or dry conditions. The 180 mm front rotor and 160 mm rear rotor shed heat well on long descents.
7-Speed Drivetrain
A 7-Speed Shimano derailleur gives a gear range wide enough to spin comfortably up a steep climb and still hit a comfortable cadence on the flats. The Shimano rear cassette is paired with a single chainring for low-maintenance daily riding.
Center-Mounted LCD Display
The backlit center display shows speed, battery level, assist mode, odometer, and trip distance at a glance. Buttons on the left grip let the rider change assist levels and motor mode without taking a hand off the bar.
Integrated LED Lighting
A front headlight and rear brake light run off the main battery, so there is nothing extra to charge. The light is wired through the controller so it does not need its own switch.
Overview
Built for the ride ahead.
The HKM-3586643 puts two 1000 W brushless hub motors - one in each wheel - behind a 48 V 20 Ah (~960 Wh) removable battery. The dual-motor layout delivers true all-wheel-drive traction, so the bike keeps moving on loose gravel, wet grass, packed snow, and soft sand where a single-motor e-bike would spin a wheel. Switch between front, rear, or both motors with the handlebar-mounted mode button; the controller automatically balances power between the two drives. Fat 26 x 4.0 in tires provide the footprint of a motorcycle tire, distributing weight over a much larger contact patch than a standard 2.4 in MTB tire. Combined with full suspension - an air-sprung fork up front and a frame-mounted rear shock - the bike absorbs small bumps and big hits with equal composure. 7-Speed Shimano gearing gives a wide enough range to spin up climbs, and hydraulic disc brakes at both ends provide the stopping power a 31 mph bike demands.
Every Component Chosen for Real-World Use
Every component of the HKM-3586643 is chosen for real-world use.
It is built to be ridden regularly, cleaned easily, and kept in top condition with routine care. The HKM-3586643 pairs a Dual 1000 W Brushless Hub (Front + Rear), 20 Ah (~960 Wh), engineered for dependable day-to-day performance, so it is built for real-world rides rather than showroom specs.

Daily Use & Care
A short routine keeps the ride quiet and the range where it should be.
Start the battery with the keyed switch on the cradle, then long-press the power button on the display for three seconds.
Mount the bike with the saddle at hip height - the recommended saddle height leaves a slight bend in the knee at the bottom of the pedal stroke.
Pedal off in single-motor mode to feel out the brakes and the bike's weight before engaging dual-motor full power.
Lean the bike against a wall or use the kickstand when parking - the full-suspension frame is heavy at ~78 lb even before adding cargo or a passenger.

Why Choose the HKM-3586643
4 reasons it earns its place.
True All-Wheel Drive
Dual motors mean the bike can climb loose gravel, wet grass, and packed snow where a single-motor e-bike would spin a wheel. The handlebar-mounted switch lets you choose front-only, rear-only, or both motors on the fly.
Big Pack
At 960 Wh the integrated battery is larger than most competitors in this price tier. Single-motor mode in low assist tops 55 mi - enough for a full day of trail riding.
Fat Tires + Full Suspension
The 26 x 4.0 in tires float over terrain that would stop a normal mountain bike, and full suspension keeps the chassis composed at speed. Together they make this the most versatile bike in the HKM line.
Hydraulic Disc Brakes
Front 180 mm and rear 160 mm hydraulic disc brakes deliver confident stopping in wet or dry conditions - essential for a 31 mph bike carrying 330 lb.
From Frame to Wheels
From the frame to the wheels, the HKM-3586643 is built for consistent, confident performance.
The specifications above show exactly what is under the surface, and the ride proves it every time. The HKM-3586643 pairs a Dual 1000 W Brushless Hub (Front + Rear), 20 Ah (~960 Wh), engineered for dependable day-to-day performance, so it is built for real-world rides rather than showroom specs.

Frequently Asked Questions
Quick answers about the HKM-3586643.
Does the HKM-3586643 require assembly?
The bike arrives 85 percent pre-assembled. You will need to install the front wheel, attach the handlebar, mount the pedals, and adjust the seat post. The whole process takes 30 to 45 minutes with the included tool kit.
Is the battery waterproof?
The pack is rated IPX4 - splash-proof from any direction, but not submersible. Riding in rain is fine. Pressure-washing the battery cavity or submerging the pack in water will void the warranty.
Can I ride the bike without the battery?
Yes. Both hub motors freewheel when unpowered, so the bike pedals like a normal bicycle. Without assist the 78 lb weight is heavier than a non-electric MTB, so expect to work harder on climbs.
How fast can the bike go?
On dual-motor throttle with full battery, the HKM-3586643 reaches 31 mph (50 km/h) on flat ground. Single-motor pedal-assist mode is limited to 28 mph per US Class 3 regulations.
What is the warranty?
Two years on the frame, one year on the motors, battery, and controller. Wear items (tires, brake pads, chain) are not covered.
Quick Troubleshooting
Common issues and what to check first.
Top speed feels lower than expected
Cold weather and a low battery both reduce motor output. Check the battery level and confirm both motors are engaged. Verify tire pressure is at least 20 PSI - soft tires rob range and speed.
Battery will not charge
Confirm the charger LED turns red when plugged into the battery. If the LED stays green, the battery is already full or the charger is faulty. If the LED is dark, check the wall outlet and the charger fuse.
Display will not power on
Confirm the battery is locked into the frame and the power button is held for at least three seconds. Check the keyed switch on the battery cradle - the pack must be clicked fully home.
One motor is not engaging
Switch motor mode through all three settings to isolate the issue. If one motor stays silent, check the motor cable connector under the frame near the affected wheel. A loose connector is the most common cause.
Range is shorter than advertised
Cold weather reduces usable battery capacity by 15-30 percent. Hilly terrain and a heavy rider also pull more current. Switch to single-motor mode when range matters.

Pre-Ride Safety Checklist
Run through these before every ride.
Check tire pressure with a gauge - both tires should be at least 20 PSI for soft surfaces and 25 PSI for paved use.
Squeeze each brake lever and confirm the rotor bites firm within half an inch of lever travel.
Lift the battery by the handle and confirm it locks fully into the cradle - a partially seated pack will cut power mid-ride.
Look at the display - the battery bar should show at least three of five segments before heading out.
Switch motor mode through front-only, rear-only, and dual-motor to confirm all three systems respond before riding.

Important Safety Notes
Read before the first ride.
This 1000 W bike is rated at 37 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; a certified downhill or motorcycle helmet is wise at 37 mph. Do not exceed the 330 lb (150 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.
