High-Energy Lithium Battery System

At the core of the HKM-501843 lies a 48V 15.6Ah lithium-ion battery (748.8 watt-hours), built with premium 21700 cells to deliver outstanding energy density and cycle life. A sophisticated Battery Management System (BMS) continuously safeguards against overcharge, over-discharge, and temperature extremes, extending the pack's longevity to over 800 complete charge cycles. The integrated downtube placement creates a clean silhouette and lowers the center of gravity, noticeably improving handling.

  • Nominal capacity 15.6Ah (748.8Wh)
  • Charge time 4–6 hours (54.6V 2A smart charger)
  • Integrated, non-removable design (IP65 enclosure)
  • BMS protection: overcharge, deep discharge, short circuit

Real‑world range varies depending on rider weight, terrain, assist level, and weather. In Eco mode with moderate pedaling, you can expect up to 37.3 miles (60 km). Even in more demanding Sport mode with frequent throttle use, the battery reliably delivers 19.3 miles (31 km). The included 2‑amp smart charger automatically stops once the battery reaches full capacity, preserving cell health for years of dependable performance.


Responsive Rear Hub Motor

The brushless rear hub motor delivers a nominal 250W with a peak output of 500W, providing seamless acceleration and a whisper‑quiet ride. Its planetary gear system reduces noise and vibration, letting you enjoy the urban soundscape without distraction. The single‑speed transmission eliminates derailleurs and shifters, meaning less maintenance and more focus on the road ahead.

Instant Torque

Quick starts from every stoplight

Cadence Sensor

Smooth pedal assist without surges

Three assist levels — Eco, Normal, and Sport — let you tailor the riding experience. In Eco, the motor sips energy to extend range; Sport unleashes full power for steep inclines or headwinds. A convenient thumb throttle allows pure electric propulsion when you want to rest your legs, while the walk‑assist mode helps maneuver the bike through narrow corridors or up ramps at walking speed.

Top speed is electronically limited based on regional regulations, but the bike can achieve 18.6 to 31.1 mph (30 to 50 km/h) depending on the selected mode and local settings. The motor’s efficiency ensures minimal battery consumption even at higher speeds, giving you confidence on longer journeys.


Aerospace‑Grade Aluminum Frame

Constructed from 6061 aircraft‑grade aluminum alloy, the HKM-501843 frame offers an ideal blend of lightness and structural rigidity. Weighing only 47.6 lbs (21.6 kg) including the battery, the bike is easy to lift onto public transport or store in tight urban spaces. Hydroformed tubing and reinforced welds ensure it can handle a maximum rider weight of 300 lbs (136 kg) without compromise.

Low‑Step Geometry

Easy mounting and dismounting

Internal Cable Routing

Clean look and better aerodynamics

Optimized Weight Distribution

Integrated battery lowers center of gravity

Custom Color Finishes

Durable powder coat, multiple shades


All‑Day Riding Comfort

Long rides demand superior ergonomics. The HKM-501843 features an adjustable Velo saddle with a pressure‑relief channel, accommodating riders from 5’3” to 6’5” (160 cm to 195 cm). Wide swept‑back aluminum handlebars encourage an upright posture that reduces strain on the neck and lower back, while lock‑on rubber grips with micro‑texture provide secure hold even in rain.

26" x 2.1" Tires

Puncture‑resistant, vibration‑absorbing

Alloy Rims

Double‑wall, lightweight strength

The rigid front fork delivers precise steering feedback, while the wide tire contact patch naturally damps road irregularities. Together, they offer a planted, confidence‑inspiring feel on pavement and well‑packed trails alike. The pedal platform is designed around a natural 68° seat tube angle, placing your legs in an efficient biomechanical position for sustained pedaling.


Confident Stopping Power & Visibility

Safety is paramount. The HKM-501843 is equipped with Tektro mechanical disc brakes paired with 160mm rotors front and rear. These brakes deliver consistent modulation and stopping power in wet or dry conditions, requiring less hand effort than rim brakes. Maintenance is straightforward, with externally adjustable pads that can be serviced without removing the wheels.

160mm Rotors

Reliable heat dissipation

Integrated LED Lights

Headlight & brake‑activated taillight

A super‑bright LED headlight illuminates the path ahead with a focused beam, while the rear light intensifies when braking to alert traffic behind you. Reflective striping on the tire sidewalls adds passive visibility from all angles. For audible warnings, a discreet thumb‑activated electronic bell provides a clear, pleasant tone that respects shared paths.


Intuitive 3.5″ LCD Smart Display

The backlit 3.5‑inch LCD display puts all essential ride data in your line of sight. At a glance, you can monitor current speed, battery level (with 5‑bar indicator), trip distance, odometer, assist mode, and estimated remaining range. The display is rated IPX6 water‑resistant, so rain and road spray won’t interrupt your ride.

  • Bright backlit LCD, readable in direct sunlight
  • Three assist levels switchable on the fly
  • Walk‑assist mode with 3.1 mph (5 km/h) limit
  • Thumb throttle for instant electric drive

The simple button pad, mounted within thumb’s reach on the handlebar, allows you to change assist levels, activate walk mode, and toggle the lights without taking your hands off the grips. This design keeps your focus on the journey while delivering a truly connected riding experience.


Why the HKM-501843 Stands Apart

Unmatched Integration

Battery hidden in downtube for sleek aesthetics and protection

Minimal Maintenance

Single-speed drivetrain, no derailleur adjustments needed

Quiet Operation

Planetary gear motor reduces noise for peaceful rides

Adaptable Performance

Frequently Asked Questions

How far can I travel on a single charge?

Real‑world range is typically 19.3–37.3 miles (31–60 km), influenced by assist level, terrain, rider weight, and weather. In Eco mode on flat ground, expect the higher end; using Sport mode and throttle will reduce range.

Is the battery removable?

The battery is integrated within the downtube for optimal weight distribution and protection. It is not designed for daily removal, but can be charged directly on the bike via the waterproof charging port. This design enhances frame rigidity and aesthetics.

What is the maximum speed?

The bike can reach 18.6–31.1 mph (30–50 km/h) depending on assist mode and local speed restrictions. Actual top speed is electronically governed to comply with regional e‑bike regulations.

How long does it take to charge?

Using the included 54.6V 2A smart charger, a full charge takes 4–6 hours. The charger automatically stops when the battery is full, preventing overcharging.

Does it have pedal assist and throttle?

Yes, the HKM-501843 offers both cadence‑based pedal assist with three levels and a convenient thumb throttle for electric‑only propulsion when you don’t feel like pedaling.

What is the rider height range?

The saddle and handlebar adjustability accommodate riders from approximately 5’3” to 6’5” (160 cm to 195 cm).

Can I ride in the rain?

Absolutely. The electronics are rated IP65 (battery and display IPX6), meaning they are protected against water jets and rain. We still recommend storing the bike in a dry place when not in use.

How much does the bike weigh?

The total weight including the integrated battery is 47.6 lbs (21.6 kg), which is competitive for a full‑size aluminum e‑bike with this battery capacity.

For work or casual wear, this polo is a great choice.
Material Type: Recycled Polyester, Color: Port Stripe, Size: X-Large
I really like this polo. I've been wearing it once a week or every other week since November. Its very comfortable and breathable. This polo feels like it should last a while. The fit is good. I typcally wear XL and this XL fits great. I've pruchased it in both burgundy and black so far. I definitely recommend this shirt. For work or casual wear, this will look good.
