HEDATX HKM-488339 Mid Motor Electric Bike

Precision mid-drive engineering for the modern commuter — balanced, powerful, and relentlessly efficient.

Experience a new standard in urban mobility with the HKM-488339. Its centrally mounted brushless motor and integrated battery create a harmonious blend of performance and aesthetics. Whether slicing through city traffic or exploring country lanes, every component is tuned to deliver a ride that feels natural, responsive, and exhilarating.

Mid-Drive Precision

Central motor placement lowers the center of gravity, resulting in superior balance and handling.

Extended Range

Travel up to 37.3 miles (60 km) on a single charge with the efficient 48V 13Ah lithium battery.

Responsive Speed

Reach speeds between 18.6–31 mph (30–50 km/h), adaptable to your riding style and conditions.

29" Stability

Large wheels absorb bumps effortlessly, ensuring a smooth, controlled ride on varied surfaces.

7-Speed Adaptability

Conquer steep inclines or enjoy flat cruising with a reliable 7-speed drivetrain.

Hydraulic Disc Brakes

Confident stopping power in wet or dry conditions, with low maintenance hydraulic actuation.

Engineered for the Ride

The HKM-488339 is not just an electric bike — it is a carefully orchestrated system where every component works in synergy. The mid-drive motor leverages the bike's gears, optimizing torque and efficiency across all speeds. This translates to a ride that feels intuitive, whether you're starting from a stoplight or maintaining a steady cadence on open roads.

Mid-Drive Motor Dynamics

Unlike hub motors, the mid-drive unit delivers power directly through the chain, allowing you to take full advantage of the 7-speed gear system. This means higher efficiency on hills and a more natural pedaling feel. The 250W brushless motor provides smooth, near-silent assistance, while advanced sensors measure your pedaling input to deliver proportionate power — no sudden surges, just seamless acceleration.

Integrated Lithium Power

The 48V 13Ah (624Wh) battery is seamlessly integrated into the downtube, preserving the bike’s clean silhouette while protecting the cells from the elements. This high-density pack delivers a real-world range of over 37.3 miles (60 km) per charge, depending on terrain and assist level. Intelligent Battery Management System (BMS) safeguards against overcharge, over-discharge, and temperature extremes, extending overall battery life.

Hydraulic Braking Confidence

Hydraulic disc brakes offer superior modulation and fade-free performance. Whether navigating rainy city streets or descending a winding trail, the 180mm rotors provide consistent, powerful stopping. The sealed hydraulic system requires minimal maintenance, ensuring your brakes feel crisp and responsive mile after mile.

7-Speed Drivetrain

Adapt to every gradient with a wide-range 7-speed gearing system. The combination of electric assist and mechanical gears gives you the flexibility to spin comfortably up steep climbs or push higher speeds on flats. The precise shifting ensures you're always in the optimal cadence zone.

Why a Mid-Drive Motor?

Optimized Weight Distribution

Placing the motor at the bottom bracket centralizes mass, dramatically improving balance and cornering stability compared to rear-hub designs.

Efficient Power Transfer

The motor drives the chain directly, using the bike’s gears to multiply torque when climbing and reduce motor RPM at speed — extending range and reducing wear.

Natural Pedal Feel

Torque and cadence sensors precisely mirror your input, delivering assistance that feels like an extension of your own strength — never artificial.

Long-Term Reliability

Mid-drive systems are renowned for their durability. Serviceable components and lower heat buildup contribute to a longer lifespan under demanding conditions.

Frequently Asked Questions
How does the mid-drive motor improve my riding experience?
The mid-drive motor delivers power directly through the bike’s chain, allowing the motor to benefit from the same gear ratios you use. This means stronger hill climbing, better efficiency, and a more natural pedal feel compared to hub motors. It also centralizes weight for superior balance and handling.
What is the real-world range I can expect?
Range depends on terrain, rider weight, assist level, and pedaling input. In typical mixed conditions with moderate assist, you can expect up to 37.3 miles (60 km). Riders using lower assist levels and contributing more pedal power may exceed this figure.
Is the battery removable for charging?
The battery is elegantly integrated into the frame for aesthetics and protection. While it is not designed for quick daily removal, it can be accessed for service by a qualified technician. The bike includes a charging port directly on the frame for convenient at-home or office charging.
What kind of maintenance do the hydraulic brakes require?
Hydraulic disc brakes are largely self-adjusting and require minimal routine maintenance. We recommend an annual brake fluid check and pad inspection to ensure optimal performance. The sealed system provides consistent lever feel in all weather conditions.
How does the 7-speed gear system complement the motor?
With 7 gears, you can select a lower gear for steep climbs (allowing the motor to operate at an efficient RPM) or a higher gear for flat roads and higher speeds. This synergy reduces strain on both the motor and your knees, enhancing overall ride comfort and battery life.

CLEAN Supplement w/Positive Benefits
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
Very PURE supplement. No extremely nasty fillers or chemical compounds which is hard to find today on the market. I feel as though it's helping slightly with my energy levels, with Mag. Malate being the key. I take one every morning on an empty stomach with a probiotic and 24oz of water. Then a Mag. Glycinate at night to encourage sleep. The combination of these two Magnesium's have encouraged more regular bathroom visits for me when consistently taken (do not exceed 400mg-500mg or severe laxative effects can take place). It is a larger pill but I have not had issues with swallowing- as I can have with others. Yes, a bit more costly than similar types but this brand focuses on main ingredients. Will buy again! Impressed with the company's quality and transparency.

Finally Found a Magnesium That Works Without Side Effects
Size: 180 Count (Pack of 1)
I started taking this magnesium because I was dealing with frequent leg cramps, especially at night, and it has made a huge difference for me. Since using this brand consistently, my cramps have almost completely disappeared and my muscles feel much more relaxed. Another thing I really appreciate is that it does not upset my stomach or cause diarrhea like other magnesium supplements I tried before. After testing several brands, this is the only one that has worked well for me without uncomfortable side effects.
