HKM-0080467 48V 1200W Electric Dual-Battery All-Terrain Bike, Dual Battery System, 31 mph Top Speed, 20 x 4.0 in Fat Tires
HKM-0080467
1200 W 31 mph Electric Dual-Battery All-Terrain Bike
The HKM-0080467 centers on its dual-battery architecture. A primary 48 V 20 Ah lithium pack mounts in the downtube as on a standard e-bike, while a secondary battery of matching capacity installs above the rear rack.
Key Features
8 details that make the HKM-0080467 a dependable ride.
1200 W High-Torque Rear Hub Motor
A 1200 W peak-rated hub motor delivers 80 N.m of torque directly to the rear wheel. Strong low-end response gets you moving quickly from stops, and sustained torque output handles steep grades and headwinds without straining the battery controller.
Dual-Battery System for Extended Range
Two 48 V 20 Ah lithium packs combine for up to 1920 Wh of total energy storage. The main battery lives in the downtube; the secondary battery mounts over the rear rack. Run on one battery for shorter trips or both for maximum range up to 120 miles.
Up to 120 Miles of Riding Range
With both batteries fully charged and moderate pedal-assist on mixed terrain, measured range reaches up to 120 miles. Even aggressive throttle-heavy riding returns 60+ miles from the combined capacity - enough for all-day adventures without charging stops.
48 V 20 Ah Removable Lithium Packs (960 Wh Each)
Both batteries are removable with keys for indoor charging. Each pack stores 960 Wh independently, so you can charge one while riding on the other if you carry a spare, or charge both overnight for a full next-day start.
Hydraulic Disc Brakes Front and Rear
Sealed hydraulic lines actuate both calipers for consistent lever feel in all conditions. Power-off brake cut-off sensors disable the motor instantly when either brake lever is pulled - essential safety on a 31 mph bike.
7-Speed Shimano Derailleur Drivetrain
A Shimano 7-speed cassette and index shifter give reliable shifting across a wide gear range. Pedal contribution significantly extends range on a dual-battery setup where the limiting factor is often time rather than energy.
Heavy-Duty Rear Cargo Rack
An integrated aluminum rear rack supports panniers, hard-shell bags, camping gear, or groceries. Rated for approximately 50 lb of distributed cargo weight with multiple strap points and bungee cord hooks.
Angular Aluminum MTB-Style Frame
The frame geometry takes inspiration from mountain bike design with an angled top tube and forward riding position suited to longer-distance riding and light off-road use. The 6061 aluminum construction keeps weight reasonable while maintaining strength for loaded touring.
Overview
Built for the ride ahead.
The HKM-0080467 centers on its dual-battery architecture. A primary 48 V 20 Ah lithium pack mounts in the downtube as on a standard e-bike, while a secondary battery of matching capacity installs above the rear rack. Together they store up to 1920 Wh of energy - roughly double the capacity of most single-battery commuters - giving you genuine freedom from range anxiety on rides of 60 miles or more. Power delivery comes from a 1200 W motor producing 80 N.m of torque at the rear wheel. That is enough torque to accelerate confidently from stoplights and climb sustained grades that would slow lesser bikes. Top speed reaches 31 mph in throttle-only mode, making this bike suitable for fast commutes and open-road cruising. The frame uses an angular MTB-inspired geometry rather than the step-through layout of city cruisers.
Engineered Around the Details That Matter
The HKM-0080467 is engineered around the details that matter for everyday riding.
Every detail is chosen to make the ride smoother, safer, and more dependable, from the frame geometry to the final finish.

Frequently Asked Questions
Quick answers about the HKM-0080467.
How does the dual-battery system work in practice?
Both batteries connect to the same controller and discharge together automatically. The display shows combined state of charge. You do not need to manually switch between batteries - the system draws from both simultaneously for balanced discharge and maximum range.
What is realistic range with both batteries?
With moderate pedal-assist on mixed terrain: 90-120 mi. Throttle-only on flat pavement: 60-80 mi. Aggressive off-road riding with frequent hills: 50-70 mi. Range varies significantly with terrain, rider weight, tire pressure, and how much you pedal.
Can I ride on just one battery?
Yes. Install only one battery if you prefer a lighter bike for shorter rides. Range with a single battery is roughly half the dual-battery figures: 45-60 mi with moderate assist, 30-40 mi throttle-only.
How long does it take to charge both batteries?
About 6-7 hours per battery with the single included charger, charged sequentially (12-14 hours total). If you add a second charger, both can charge simultaneously in 6-7 hours.
Is the MTB-style frame comfortable for long rides?
The more forward riding position suits riders who want an efficient pedaling posture for distance riding. Combined with the fat tires and front suspension, the bike remains comfortable on multi-hour rides across varied surfaces.
How much cargo can the rear rack carry?
The integrated aluminum rack is rated for approximately 50 lb of distributed cargo weight. Use panniers for heavy items, strap lighter loads directly to the rack deck, and keep the center of gravity low for stable handling.
Do I need to pedal with such a large battery?
You can ride entirely on throttle if you choose. However, pedaling extends range significantly even with 1920 Wh on board, because time rather than energy becomes the limiting factor on very long rides. Pedaling also provides exercise and reduces motor strain on steep climbs.
What maintenance does the dual-battery system need?
Beyond standard e-bike care, ensure both batteries stay reasonably balanced in charge level by running them together most of the time. If one battery sits unused for months while the other gets regular cycling, recharge the stored one periodically to maintain cell health.
Quick Troubleshooting
Common issues and what to check first.
One battery drains faster than the other.
This is normal if one battery is older or has been through more charge cycles than the other. The controller balances discharge, but cells with different aging profiles will show slightly different voltage sag under load. Consider replacing both batteries together when one reaches end of service life.
Range seems lower than the stated 120 miles.
Measured range assumes moderate pedal-assist on relatively flat terrain with a solo rider at recommended tire pressure. Aggressive throttle use, hilly terrain, two-up riding, cold weather, underinflated tires, and heavy cargo all reduce real-world range significantly.
The motor cuts out intermittently on steep climbs.
This may be thermal protection engaging under sustained high-current draw. Reduce throttle input, shift to a lower gear, and add pedal input to share the load with the motor. If cutting out happens immediately on a cool motor, check battery connector seating and charge level.
The hydraulic brakes feel inconsistent between front and rear.
One caliper may have air in the line or uneven pad wear. Have the system inspected and bled by a qualified mechanic. Also check that rotor surfaces are clean and free of oil contamination.
The display shows unusual battery readings after installing the second battery.
Confirm the second battery connector is fully seated and locked. Power cycle the system off for 30 seconds and back on. If readings remain incorrect, check that both batteries are compatible and have similar charge levels.
The cargo rack rattles over bumps.
Check all rack mount bolts are torqued to specification. Add rubber washers between the rack and frame contact points if rattling persists. Ensure cargo is secured tightly and not shifting during the ride.

Important Safety Notes
Read before the first ride.
This 1200 W bike is rated at 31 mph. Read the manual first and practise throttle and braking in an open, traffic-free area. Leave extra room for braking, since stopping distance grows fast with speed and load. Wear a helmet every ride; a certified downhill or motorcycle helmet is wise at 31 mph. Do not exceed the 350 lb (159 kg) load limit, including rider, cargo, and rack load. Confirm local law before riding on public roads. Bed the brakes in with 10-15 progressive stops over the first rides. Never ride through water deep enough to reach the motor or battery. Charge only with the supplied charger, indoors and attended. Never open, puncture, or modify the pack. Slow down substantially on gravel, wet surfaces, and steep descents.
