Intelligent Power Delivery

The heart of the HKM‑370771 is a 48V 500W geared hub motor, meticulously tuned for urban cargo duties. Unlike direct‑drive alternatives, the geared mechanism amplifies torque at low RPM, delivering smooth starts even under heavy load. The motor controller uses sine‑wave modulation, which means you’ll experience whisper‑quiet operation and seamless acceleration — no abrupt jerks, just refined thrust. From standing starts at traffic lights to sustained cruising at 19 – 31 mph (30 – 50 km/h), this drive unit adapts instantly. The integrated pedal‑assist sensor responds within milliseconds, giving you a natural, intuitive riding feel that respects your effort.

Endurance‑Tuned Battery & Range

A 48V 14Ah lithium‑ion pack (672 Wh) is seamlessly concealed within the downtube, preserving the bike’s clean silhouette while protecting cells from weather and impact. On a full charge — achieved in just 3 to 4 hours — you’ll cover 20 to 37 miles (31 to 60 km), depending on assist level, cargo weight, and terrain. The smart battery management system (BMS) monitors temperature, voltage, and current in real time, extending cell lifespan and ensuring consistent output down to the last percentage. Whether you’re running a 5‑mile grocery loop or a full day of deliveries, the HKM‑370771 gives you the confidence to leave the charger at home.

Precision Handling & Ride Comfort

20‑inch wheels strike the ideal balance between compact agility and road‑holding stability. The smaller diameter lowers the center of gravity, which translates to confident cornering when the cargo rack is fully loaded. An adjustable stem lets you fine‑tune handlebar height and sweep, accommodating riders from approximately 5′4″ to 6′4″ (163 to 193 cm) without compromise. The lightweight aluminum alloy frame absorbs high‑frequency vibrations, yet remains torsionally stiff enough for precise steering. Combined with the step‑through‑friendly geometry, the HKM‑370771 offers an upright, commanding view of the road — a must for busy streets.

Safety‑Forward Braking System

Stopping a loaded cargo bike demands serious hardware. The HKM‑370771 answers with hydraulic disc brakes front and rear, delivering consistent bite in wet or dry conditions. An integrated motor cutoff switch in the brake lever instantly disengages drive power the moment you squeeze, preventing unintended acceleration during emergency stops. The brake calipers are tucked away from cargo interference, and the large rotors dissipate heat effectively on long descents. With responsive, low‑maintenance hydraulics, you’ll ride with the same assured braking feel as premium mountain bikes.

Versatile 7‑Speed Drivetrain

A genuine Shimano 7‑speed derailleur system gives you the flexibility to conquer varied topography. Shift effortlessly through the gear range while maintaining optimal cadence — low gears for loaded starts and steep ramps, high gears for open‑road cruising. The indexed shifter provides positive, tactile feedback, and the chain tensioner keeps everything running quietly even when you’re navigating broken pavement. Combined with the motor’s torque, the drivetrain ensures you never feel under‑geared, regardless of cargo weight.

Purposeful Cargo Utility

Every element of the HKM‑370771 is engineered with hauling in mind. The elongated rear rack provides a spacious platform for panniers, crates, or child seats. Integrated mounting points allow secure attachment of straps and accessories, and the low‑profile design makes loading effortless. A sturdy double‑leg kickstand keeps the bike upright even when packed with groceries, while the optional front rack (available separately) extends carrying capacity for larger items. From farmers’ market runs to daily commutes with a change of clothes, this bike transforms how you move goods through the city.

Built to Endure the Everyday

Durability is at the core of the HKM‑370771. The aluminum alloy frame is treated with a multi‑layer anti‑corrosion coating, ready for all‑season riding. Stainless steel spokes and sealed bearings in the wheel hubs resist rust and reduce maintenance. The electronics are rated for water and dust resistance (IPX5 level), so you can confidently park outside or ride through unexpected showers. Thoughtful touches like reinforced dropouts and internally routed cables protect vital components, ensuring your investment stays reliable for thousands of miles.

Why the HKM‑370771 Stands Out

Designed for the real world. Many electric cargo bikes compromise on geometry or component quality to hit a price point. The HKM‑370771 takes a different path: a name‑brand Shimano drivetrain, full hydraulic brakes, and a battery integrated into the frame’s structure. The result is a bike that feels as polished as premium European models, yet remains accessible. With a 500W geared motor — not an underpowered 250W unit — you maintain momentum even when the rack is fully loaded. And because the battery is frame‑integrated, you don’t sacrifice lockability or aesthetics. It’s the daily tool that’s ready to work as hard as you do.

  • Torque‑rich geared hub motor outperforms many direct‑drive competitors in low‑speed hauling.
  • 14Ah battery with smart BMS offers real‑world usable range, not just inflated lab figures.
  • Hydraulic disc brakes with motor cutoff — a safety feature often omitted on cargo bikes in this class.
  • Adjustable stem and 20″ wheels deliver a custom fit for diverse rider statures.
  • Modular cargo platform ready for panniers, child seats, or custom storage solutions.

? Frequently Asked Questions

What is the actual range I can expect on a single charge?

Range varies with assist level, rider weight, cargo, terrain, and temperature. Under typical mixed urban riding with moderate pedal assist, expect 20 – 37 miles (31 – 60 km). Using maximum assist continuously will lean toward the lower end, while eco mode can surpass 37 miles under favorable conditions.

Can the battery be removed for charging?

The battery is integrated into the frame for security and a clean look, and it can be charged directly on the bike via the side charging port. This design protects the battery from theft and weather, while still offering convenient overnight charging.

Is this bike suitable for steep hills?

Absolutely. The 500W geared hub motor produces high torque at low speeds, and the 7‑speed Shimano drivetrain lets you select a low gear for climbing. Together they tackle grades over 15% with a loaded rear rack.

What kind of maintenance does the HKM‑370771 require?

Routine maintenance is similar to a traditional bicycle: keep the chain lubricated, check tire pressure, and periodically inspect brake pads. The hydraulic brakes are self‑adjusting to a degree, and the motor requires no special servicing. We recommend an annual check‑up by a qualified e‑bike technician.

Can I install a child seat or additional cargo accessories?

Yes, the rear rack is compatible with most standard pannier bags, child seats, and cargo crates. There are multiple M5 and M6 mounting points. Front rack options are also available separately to further expand your hauling capability.

Pass on this one.
It's hard plastic, which doesn't make for a fun experience for either the dog, or our floors. It doesn't stay charged for long either. I wasn't impressed at all...and neither was the dog.

Fun and durable toy
Lots of fun for this crazy guy! He pounces on it, chases it and has so much fun. The confusion on his face is so funny. He usually gets bored fast, however this ball keeps him quite entertained. The ball holds a charge for a few playtimes so that is also a plus!

Great toy, too bad my Shih Tzu is afraid of it. I love the way the movement is subtle and random.
