HKM-9339347
Electric Trekking Bike
The HKM-9339347 is a city trekking e-bike built for the daily loop: a 250 W rear hub motor, a 36 V 13.5 Ah battery good for 31-37 mi, Shimano 8-speed gearing on 700 C wheels, and hydraulic disc brakes. Rack and fenders come fitted, and the LCD color screen keeps speed, charge, and mileage in view.
Key Features
Eight details that make the HKM-9339347 a dependable daily ride.
250W Rear Hub Motor
A 250 W brushless hub motor in the rear wheel delivers smooth, quiet assist through the pedals. It is the difference between a spec sheet and a ride you look forward to.
36V 13.5 Ah Battery
The 36 V 13.5 Ah lithium pack rides integrated in the down tube, so the bike handles like a bicycle first. That is hardware documented in the spec sheet below, not brochure copy.
31-37 mi Real Range
Up to 31 mi on pure electric and 37 mi with pedal assist - the week’s errands on one charge. It is one of the specifications the rest of this page keeps coming back to.
Shimano 8-Speed Gearing
A Shimano 8-speed drivetrain with 12-32 T cassette keeps cadence honest on climbs and flats. Across the page, the HKM-9339347 keeps the same standard everywhere.
700C Trekking Wheels
700 C wheels with 38 mm tires roll over seams and cuts that rattle smaller hoops. Owners notice it in the first week - and every week after.
Hydraulic Disc Brakes
Hydraulic disc brakes bite with one finger and stay consistent in wet traffic. Riders notice it most on the hills and the long way home.
LCD Color Screen
The color LCD shows speed, battery level, gear, and mileage at a glance. On the HKM-9339347, that figure is backed by hardware sized to the same standard.
Rack & Fenders Included
A full rear rack plus front and rear fenders come fitted - cargo and clean clothes included. It is the difference between a spec sheet and a ride you look forward to.
Overview
A steady motor, honest range, city-ready hardware.
The HKM-9339347 is built for riders who want one bike for everything: a 250 W rear hub motor, a 36 V 13.5 Ah battery with 31-37 mi of range, Shimano 8-speed gearing on 700 C wheels, and hydraulic disc brakes. The LCD color screen keeps speed and charge in view, and the rack and fenders are fitted, not optional.
Assembled and Examined
The ride, before the ride.
Hardware on the HKM-9339347 - motor mount, rack, and braking - is finished and fastened for daily duty. Study the details: it is the same machine that arrives at your door.
Full Specifications
Measurements are shown in US customary units first, with metric equivalents in parentheses.
Battery, Range, and Charging
Range for the whole week.
The 36 V 13.5 Ah pack covers 31 mi on pure electric and 37 mi with assist - city distances, covered for days. Real-world range moves with assist level, terrain, and rider input, and the honest answer is the one every rider eventually prefers.
Daily Use & Care
A short weekly routine keeps the ride quiet and the parts alive.
Wipe the aluminum frame with a damp cloth after wet rides - no pressure washer, ever.
Rinse off road salt after winter riding, then dry the drivetrain by hand.
Check the axle, stem, and rack bolts before the first ride of each week.
Inspect hydraulic brake pads monthly. Pads wear silently until they are gone; replace early.
Charge indoors at room temperature; a 6-8 hour charge covers a full pack from empty.
Keep the charge-port cover closed between charges so moisture stays out.
Keep the chain clean and lubed; a dry chain wears the 8-speed cassette fast.
Spin both wheels weekly and check that nothing rubs and the tires seat evenly.

Why Choose the HKM-9339347
Eight reasons it earns its place by the door.
Commuter Math
At 16 mph assist with 31-37 mi of range, the car stays parked for most daily trips. That is hardware documented in the spec sheet below, not brochure copy.
Front Suspension Comfort
A suspension fork takes the edge off potholes and curb cuts instead of passing them to your wrists. Riders notice it most on the hills and the long way home.
Aluminum-Light Build
The aluminum alloy frame keeps weight down for stairs, racks, and apartment living. It is one of the specifications the rest of this page keeps coming back to.
Cargo-Ready Rear Rack
A rated rear rack carries the groceries, the laptop bag, or the weekend loadout. Across the page, the HKM-9339347 keeps the same standard everywhere.
All-Weather Fenders
Front and rear fenders throw the spray down, not up your back. Owners notice it in the first week - and every week after.
Three Ride Modes
Assisted, pure electric, or plain cycling - the HKM-9339347 switches to match the moment. It is the difference between a spec sheet and a ride you look forward to.

Rear Rack
A rated rack carries the groceries or the laptop bag, strapped and done. The manual documents each control in full.
Frequently Asked Questions
Quick answers about the HKM-9339347.
How much assembly is required?
Mostly assembled: torque-check the stem, bars, and pedals, confirm brake rotor alignment, and charge before the first ride.
How far will it go on one charge?
Up to 31 mi on pure electric and 37 mi with pedal assist. Rider weight, hills, temperature, and assist level all move the number.
How fast does it go?
16 mph, the standard legal assist limit for this class of e-bike. Confirm your local rules before riding.
How long does charging take?
6-8 hours from empty at any standard wall outlet - an overnight habit covers the work week.
Can it ride in the rain?
Yes - the electrical system is built with wet weather in mind. Wipe the frame dry afterward and charge indoors.
What accessories are included?
A rear rack plus front and rear fenders come fitted, along with the charger and user manual.
Is a helmet required?
Yes, every ride - a certified helmet is cheap insurance on any e-bike, and many jurisdictions require one.
What warranty is included?
24 Months Warranty Service, 180 Days Purchase Protection, and 30 Days Money-Back Guarantee.
Quick Troubleshooting
Common issues and what to check first.
The motor does not engage.
Confirm the battery is charged and the system is powered on, then check the cadence sensor gap at the crank.
Range dropped noticeably compared with when it was new.
Check tire pressure first; a soft tire is the most common cause. Then consider chain lube and brake rub before blaming the battery.
The brakes feel weak.
Pump the lever to re-center the pads; if the lever still reaches the bar, the hydraulic circuit needs a bleed.
Shifting is noisy under load.
Index the rear shifter a quarter turn at a time while pedaling; a bent hanger mimics a bad cable.
The display will not power on.
Confirm the pack has charge and all connectors are seated. Switch the system off, wait 30 seconds, and power on again.
The charger light never turns green.
Check the port cover is fully seated and try a different outlet before assuming the pack is at fault.
Certifications & Standards

Details Up Close
Hardware that holds.
The rear rack, fenders, and battery bay on the HKM-9339347 are sized to the same standard - nothing on this bike is an afterthought.
Pre-Ride Safety Checklist
Run through these before every ride.
Check tire pressure before every ride; soft 38 mm tires scrub range and pinch flat.
Squeeze the brake levers hard while stationary - the bike should not creep.
Confirm the battery gauge shows the charge you expect before heading out.
Spin both wheels and check that nothing rubs and the rotors run true.
Check that the axle, stem, and rack hardware are tight, with no play at the cockpit.
Confirm the drivetrain shifts cleanly through all eight gears before you commit to traffic.
Wear a helmet every ride, and use the headlight in low visibility.
Plan a route that matches your charge and your legs.

Important Safety Notes
Read before the first ride.
Wear a helmet every ride and ride only where the law allows. Read the manual first and practise shifting and braking in an open, traffic-free area before the first real ride. This is a pedal-assist bicycle for adults - do not exceed the load limit marked on the bike's components. Slow down substantially on wet surfaces, gravel, and steep descents - braking distance grows fast. Never open, puncture, or modify the battery. Charge only with the supplied charger, indoors and attended, and unplug when full.
