HKM-333779 Electric Hybrid Bike
Engineered for the modern adventurer, the HKM-333779 merges dual-motor muscle with everyday usability. A lightweight alloy chassis, fat‑tire traction, and precision Shimano shifting redefine what an electric hybrid can achieve—whether carving through city traffic or exploring backcountry trails.

Dual‑Motor Dominance
Two high‑efficiency brushless motors combine to deliver a potent 2000 W peak output. The instant response erases hesitation on steep grades and accelerates smoothly from a standstill. With 36.9–44.3 lb‑ft (50–60 N·m) of torque on tap, you’ll crest hills that stop ordinary commuter bikes in their tracks.
The electronic control unit harmonizes front and rear motor output, distributing traction intelligently. Whether you’re loaded with panniers or powering through loose gravel, the system adapts in milliseconds. No gear‑hunting, no lag—just relentless forward motion.
Twin Motor Synergy
Front & rear motors cooperate through a shared controller for seamless power delivery and regenerative braking support.
Enduring Lithium Power
48 V High‑Density Pack
Encased in a weather‑sealed housing, the battery balances energy density with thermal stability. Expect 19–37 miles (31–60 km) on a single charge, depending on assist level, terrain, and rider weight.
The intelligent BMS guards against overcharge, over‑discharge, and temperature extremes. A full recharge typically requires 4–6 hours via the included 2 A smart charger. The removable design lets you charge indoors or at your desk—no need to park near an outlet.
Four pedal‑assist modes plus a thumb throttle give you command over battery consumption. Eco mode stretches range to the maximum, while Sport unleashes the full 2000 W for adrenaline‑filled segments.
Lightweight Alloy Agility
The 6061 aluminum frame strikes an ideal balance between low weight and high fatigue resistance. Hydroformed tubes smooth out stress risers, while internal cable routing preserves the clean silhouette. At a net weight of approximately 58 lb (26.3 kg) with battery, the HKM-333779 remains manageable to lift onto a car rack or carry up a flight of stairs.
Geometry is tuned for comfort over long hours: a relaxed head angle and extended wheelbase dampen road buzz, and the low‑standover design fits riders from 5'4" to 6'4". The matte charcoal finish with subtle cyan accents looks sharp in any setting.
6061 Aluminum Chassis
Corrosion‑resistant alloy with hydroformed down tube for an optimal stiffness‑to‑weight ratio.
26″ x 4.0″ Fat‑Tire Confidence
All‑Terrain Tread
Wide contact patch and knobby pattern grip loose sand, snow, mud, and wet pavement with equal authority.
Oversized 26″×4.0″ tires run at lower pressures (5–30 psi) to absorb vibrations naturally, reducing rider fatigue. The broad footprint increases cornering stability and resists pinch flats. Double‑wall rims add durability without excess rotating mass.
Whether you’re rolling over tree roots or potholed downtown streets, the HKM-333779 floats over obstacles that would jar a skinny‑tire hybrid. The aggressive side knobs bite into soft terrain while the center ridge keeps rolling resistance low on hardpack.
Shimano 7‑Speed & Hydraulic Disc Brakes
A genuine Shimano 7‑speed rear derailleur pairs with a thumb shifter for precise gear changes under load. The wide 14‑28T cassette gives you a bailout gear for steep climbs and a tall gear for fast flats. The single‑chainring setup reduces maintenance and chain drops.
Hydraulic disc brakes with 180 mm rotors front and rear deliver superb stopping power in rain, dust, or mud. The lever feel is progressive and fatigue‑free, giving you confidence to scrub speed on long descents. The system is mineral‑oil based, requiring minimal upkeep.
Precision & Control
Shimano indexing ensures crisp shifts, while the dual‑piston calipers provide consistent pad contact.
Full‑Color LCD Command Center
Center‑Mounted Display
Bright, anti‑glare panel shows speed, battery level, assist mode, odometer, and trip distance at a glance.
The 3.5″ full‑color LCD sits flush in the stem, readable even in direct sunlight. Customize your assist level (Eco, Tour, Sport, Turbo) with a thumb control without taking your eyes off the trail. Real‑time wattage output and remaining range estimates help you plan every ride.
Integrated USB‑C port underneath the display lets you charge your phone or GPS device on the go—turning the bike into a mobile power bank.
Illuminated Safety & Ready‑to‑Ride Kit
A high‑output LED headlight (800 lumens) casts a wide beam for night riding, while the integrated tail light with brake‑light function alerts traffic. Both are powered by the main battery and controlled via the display. The horn and turn‑signal indicators (optional) add an extra layer of urban protection.
Out of the box, the HKM-333779 includes a sturdy rear cargo rack (55 lb / 25 kg capacity), full‑length mudguards to keep spray off your clothes, and a quick‑release phone holder that grips devices up to 6.7″. The package also contains the smart charger, assembly tools, and a detailed setup guide.
Full Visibility Package
Front & rear LED lights, plus reflective tire sidewalls, ensure you’re seen from every angle.

Frequently Asked Questions
What is the real‑world range on a single charge?
Range varies from 19 miles (31 km) in high‑assist Turbo mode up to 37 miles (60 km) in Eco mode. Factors like rider weight, terrain, tire pressure, and ambient temperature influence the actual distance. Using the throttle exclusively will typically yield 19–25 miles.
Does the bike operate in pedal‑assist only, or can I use the throttle?
Both modes are available. The thumb throttle provides instant electric propulsion without pedaling, while five levels of pedal assist amplify your own input. You can switch on the fly or ride completely unassisted like a traditional bicycle.
How long does it take to charge the battery?
Using the included 2 A smart charger, a full charge from empty takes approximately 4–6 hours. The charger indicator turns green once the battery reaches capacity, and the BMS automatically stops charging to protect cell health.
Is the battery removable?
Yes. The 48 V pack locks into the downtube and can be released with a key. This allows convenient indoor charging or swapping with a spare battery (sold separately).
Can I ride in the rain or through puddles?
The HKM-333779 is built to IPX5 water‑resistance standards. The motor, battery, and wiring harness are sealed against splashes and light rain. However, submerging the bike or using a high‑pressure washer is not recommended.
What maintenance do the hydraulic brakes require?
Hydraulic disc brakes are largely self‑adjusting. Check pad thickness every 300 miles and bleed the system annually or if the lever feels spongy. The mineral oil used is non‑corrosive and easy to service.
Does the bike come assembled?
The HKM-333779 arrives 85% assembled. You’ll need to attach the front wheel, handlebars, pedals, and seat post. Tools and a step‑by‑step video guide are included. Most riders complete setup in under 30 minutes.
