Next‑Generation Lithium Power System

At the core of the HKM-647187 sits a high‑density 72V 45Ah lithium‑ion battery pack — engineered for endurance and consistent power delivery. With a formidable 3.24 kWh energy reserve, the bike achieves up to 93 miles (150 km) on a single charge under typical riding conditions. The advanced Battery Management System (BMS) continuously monitors cell voltage, temperature, and state of charge, protecting against over‑charge, deep discharge, and thermal stress. Whether you are traversing forest trails or commuting across town, the pack’s optimized energy density keeps you rolling longer between charges.

Smart BMS Protection

Multi‑layer safeguards ensure battery longevity and safety in all temperatures.

Range‑Optimized Cells

High‑grade 21700 cells deliver minimal voltage sag and extended cycle life.

Mid‑Drive Brushless Motor & Instant Torque

The centrally mounted brushless motor delivers a staggering 500 Nm (369 lb‑ft) of torque directly to the drivetrain, translating into explosive acceleration and effortless climbing on gradients up to 35°. Unlike hub‑motor designs, the mid‑drive configuration preserves the bike’s balanced weight distribution and leverages the 5‑speed gearbox for optimal mechanical advantage. The result is a responsive, natural ride feel — whether you are crawling over technical rock sections or sprinting on open fire roads. The motor’s sine‑wave controller ensures whisper‑quiet operation and smooth power modulation.

Multi‑Layer Gear Reduction

Optimized internal gearing multiplies torque while keeping the motor compact and efficient.

Sine‑Wave Controller

Delivers fluid power delivery and near‑silent operation, reducing drivetrain stress.

Lightweight Alloy Frame & Full Suspension

Crafted from 6061 aluminum alloy, the frame strikes an ideal balance between rigidity and low weight, enabling nimble handling without sacrificing durability on punishing trails. The hydroformed tubes feature reinforced weldments at high‑stress junctions, while the geometry is tuned for aggressive all‑mountain riding. Paired with a full‑suspension system — featuring adjustable preload and rebound damping — the bike absorbs square‑edge impacts and successive bumps with poise, maintaining tire contact and rider confidence at speed.

6061 Aluminum Chassis

Precision‑welded frame with optimized strength‑to‑weight ratio for trail agility.

Adjustable Full Suspension

Tune compression and rebound to match terrain, from rock gardens to flow trails.

Hydraulic Disc Brakes with Precision Control

Stopping power is delivered by a set of high‑performance hydraulic oil brakes, featuring four‑piston calipers biting on large‑diameter stainless steel rotors. The system provides exceptional modulation and fade‑resistant performance, even during prolonged descents or emergency stops at top speed. Ergonomic levers offer reach adjustment, allowing riders to tailor the engagement point for maximum comfort and one‑finger braking capability. With a dual‑circuit layout, braking force remains balanced, enhancing stability when you need it most.

Oversized Wheels & All‑Terrain Rubber

Equipped with a substantial 70/100‑19 wheel set (front and rear), the HKM-647187 rolls over obstacles with authority. The wide‑profile knobby tires (approximately 3.0‑inch section width) deliver a large contact patch for superior grip on loose soil, gravel, and mud. The 19‑inch rim diameter strikes a sweet spot between rollover capability and sidewall compliance, while the aggressive tread pattern sheds debris effectively. Whether cornering on hardpack or powering through sand, the tire and wheel combination inspires confidence at all lean angles.

5‑Speed Gearbox & Seamless Shifting

The five‑speed transmission allows riders to select the perfect ratio for every situation — from steep, technical climbs that demand low‑end grunt to high‑speed sections where cadence and motor efficiency matter. The gearbox features dog‑clutch engagement for positive, reliable shifts, and is sealed against dust and moisture. The close‑ratio spread complements the motor’s broad torque curve, enabling smooth acceleration without power gaps. A gear position sensor communicates with the controller to optimize power mapping in each gear.

Frequently Asked Questions
What is the actual range on a single charge?
Range varies based on terrain, rider weight, speed, and assist level. In optimal conditions (flat terrain, Eco mode, 155 lb rider), you can achieve up to 93 miles (150 km). Aggressive off‑road use with maximum power will reduce range accordingly. The battery management system ensures consistent performance throughout the discharge cycle.
How fast does the battery recharge?
Using the included 5A smart charger, a full charge from empty takes approximately 8‑9 hours. The battery supports faster charging (up to 10A) with an optional accessory charger, reducing charge time to around 4‑5 hours. The BMS controls charge current and temperature to preserve cell health.
Is this bike street‑legal?
The HKM-647187 is designed primarily for off‑road use. Regulations vary by region; some areas classify it as a moped or motorcycle, requiring registration and a license. Please check your local laws before operating on public roads. It can be fitted with lighting and mirrors (not included) for potential homologation.
What maintenance does the drivetrain require?
The sealed gearbox requires an oil change after the first 300 miles (500 km) and then every 1,200 miles (2,000 km). The chain (if applicable) should be lubricated regularly. Hydraulic brakes need periodic fluid inspection. The battery contacts should be kept clean and dry. Full service intervals are detailed in the user manual.
Can the battery be removed for charging?
Yes, the 72V 45Ah pack is easily removable via a key‑locked mounting system. This allows you to charge indoors or swap batteries for extended riding sessions. The pack weighs approximately 38 lb (17.2 kg).

Durable
Color: Purple
I bought this for my 80lb 1yr American Bully male,who has made it his mission to test all the toys his dad and I have bought. Now I have 3 other American Bullies, siblings 3yr old 2 females/1male, who did the same at that age and I mastered toy shopping or so I thought. Lol. My new pup loves balls and this is the only one he firstly can't fit completely in his mouth and can't tear it apart. He has tired!

My Dogs Loved Them!
Color: Purple
My dogs loved these for playing fetch. They seem heavier duty than previous ones I have had. Beware of the incoming constant squeak sounds if your pup gets really into chewing it.

Shockingly, good ball!
Color: Purple, Color: Purple
I have a Doberman. She is a ball and toy destroyer. She is the most obsessive retriever I’ve ever had. Her retrieving urge, and indefatigability, puts my golden retriever to shame. Because of this, we throw the ball all the time. She is primarily an indoor dog and we have to exhaust her energy and so throwing the ball is how this is done. I got these balls in an effort to try to find something that would last longer than a few days. I have now had these 2 balls for six weeks. They are both still alive! It literally blows my mind. When I bought them, we took bets on how long they would last. I gave it a week. I lost my bet. I got the extra large size. It’s perfect for the giant jaw span of a full grown Doberman. It squeaks, which is irritating to us, but what she loves. She can lay there and chew on it and still not destroy it. They’re very heavy ball and bounce, so you have to be careful throwing it in the house cause you could hurt breakables. Whoever said that these feel like they came from the dollar tree must have been talking about something else. They are thick and sturdy balls. UPDATE: it has now been THREE MONTHS and our Doberman STILL has not destroyed these 2 balls. We play with them many times each day. WORTH EVERY PENNY ADDITIONAL UPDATE: it’s now been nine months. Took this photo this morning. We still have the balls and have since ordered two more. She chews on it multiple times every day. There’s a little hole in it now and it doesn’t squeak anymore but it’s 98% intact and still essentially indestructible. These balls are worth gold.

The dog loves 'em
Color: Blue
The dog loves the balls, and they're the right size for my German Shepherd. Lost a couple of starts because they're not very durable, the "teeth" are easily broken off, so I am frequently finding "lost teeth" across the house; the squeakers also cannot hold up to my dog's aggressive chewing. I would still buy them again, as like I said, my dog love 'em!

Dogs love them!
Color: 3 Colors
Dogs love them! Larger than your average tennis balls, satisfying for my dogs to chew on, the squeak isn't too annoying, colorful enough I can find them in the bushes.
