Designed for the Modern Commuter

The HKM‑455571 merges clean aesthetics with genuine utility. Its aluminum alloy frame keeps the weight manageable without sacrificing rigidity, while the integrated battery maintains a sleek profile that doesn’t scream “electric.” Whether you’re weaving through downtown traffic or cruising along a park path, the geometry offers an upright, comfortable position that reduces strain on your back and wrists. Thoughtful details like internal cable routing and hidden welds speak to a build quality that’s meant to be seen and felt.

Power That Keeps Up

The 350‑watt brushless rear hub motor delivers a natural-feeling assist that responds instantly to pedal input. Three assist levels let you dial in exactly the amount of help you want — from a gentle breeze at your back to a vigorous push that flattens hills. The motor is engineered to be quiet, so you’ll hear the city around you, not a mechanical whine. With a top assisted speed of 28 mph (45 km/h), you’ll arrive at your destination fresher and faster than you would on a traditional bike, without breaking a sweat.

Battery Intelligence & Range

The 48V 19.2AH lithium‑ion pack uses automotive‑grade cells arranged for balanced discharge and longevity. Hidden inside the downtube, it stays protected from the elements and potential theft. A full charge takes only 3 to 5 hours, so you can top up during a workday or overnight. Under typical pedal‑assist conditions (mixed terrain, 165 lb / 75 kg rider), the bike can cover up to 60 miles (96 km) — enough for a week of short commutes or a long weekend adventure without range anxiety. A backlit handlebar display shows remaining charge, speed, and assist level at a glance.

Built for Safety & Visibility

Riding in low light shouldn't feel like a compromise. A high‑output LED headlight cuts through the dark with a wide, even beam, while reflective accents on the frame and tires add passive visibility. The hydraulic disc brakes — with sintered pads — provide consistent, modulation‑friendly stopping power in rain or shine. Because the battery is integrated, the bike retains a clean silhouette that doesn't sacrifice safety for style.

Comfort That Lasts the Whole Ride

The 27.5‑inch wheels strike the ideal balance between nimble handling and bump absorption. Paired with a compliant aluminum fork and a padded saddle, they smooth out potholes and uneven pavement. Ergonomic grips and an adjustable stem let you fine‑tune your fit, so whether you're 5′5″ or 6′2″ (165–188 cm), you'll find a natural riding posture. The bike’s overall dimensions are approximately 72.8 × 26.4 × 43.3 inches (185 × 67 × 110 cm) with a net weight of roughly 55.1 lb (25 kg), making it substantial enough for stability yet still light enough to maneuver up a curb or onto a train.
