Unleash True Off‑Road Power

The heart of the HKM-394707 is a high-efficiency 8000‑watt brushless motor, tuned for immediate throttle response. With 330 newton‑meters (243.4 pound‑feet) of peak torque on tap, the bike climbs steep grades and powers through loose surfaces without hesitation. The electronic controller optimizes energy flow, minimizing heat buildup even during sustained high‑load riding.

Max Speed Over 31 mph (50+ km/h) — thrilling trail velocity
0–31 mph (0–50 km/h) Rapid acceleration — reaches top speed in seconds
Torque 330 Nm (243.4 lb‑ft) at the rear wheel

Endurance That Matches Your Ambition

The 72‑volt architecture paired with a 35‑Ah lithium‑ion pack offers a real‑world range of 62–81 miles (100–130 km), depending on terrain and riding style. The detachable design allows you to charge the battery on or off the bike — ideal for apartment dwellers or base‑camp setups. Intelligent Battery Management System (BMS) safeguards against overcharge, overheating, and deep discharge, extending pack life cycle by years.

35 Ah Capacity 72 V nominal, 2520 Wh total energy — ample for day‑long trail sessions.
3–5 Hour Fast Charge From empty to full while you rest. Standard 110 V / 220 V charger included.
62–81 Miles Range 100–130 km on mixed terrain. Eco mode extends distance further.

Lightweight Aluminum Alloy Chassis

The frame is forged from aerospace‑grade 6061 aluminum alloy, striking the perfect balance between rigidity and low weight. This reduces overall mass for better handling and longer battery life, while maintaining exceptional torsional strength. The welded joints are double‑pass smoothed for stress distribution, and the swingarm geometry is optimized for off‑road tracking stability.

Frame Material 6061 Aluminum Alloy — lightweight, corrosion‑resistant
Max Load 331 lbs (150 kg) — accommodates rider plus gear

Race‑Ready Suspension & Braking

Both front and rear feature fully adjustable hydraulic dampers with piggyback reservoirs, allowing fine‑tuning of compression and rebound to match rider weight and terrain. The 7.5‑inch (190 mm) travel soaks up roots, rocks, and jumps. Hydraulic disc brakes with 210 mm rotors front and rear deliver powerful, fade‑resistant stopping even in wet conditions.

Fully Adjustable Hydraulic Fork Inverted design reduces unsprung weight. Rebound & compression clickers.
Hydraulic Disc Brakes Dual 210 mm rotors, sintered pads — consistent bite and modulation.

Aggressive Traction, Any Terrain

Fitted with heavy‑duty knobby tires sized F 70/100‑19 and R 80/100‑19, the HKM‑394707 finds grip on hardpack, loam, gravel, and mud. The 19‑inch rims provide ample sidewall flex for bump absorption while resisting pinch flats. Multi‑edge tread blocks are self‑cleaning in sticky soil.

Front Tire 70/100‑19 (approx. 2.75‑19) — directional knobby
Rear Tire 80/100‑19 (approx. 3.00‑19) — wide footprint for drive

Frequently Asked Questions

What is the actual range in off-road conditions?
Range varies with terrain, rider weight, and speed. On mixed trails with moderate hills, expect 68–75 miles (110–120 km). In aggressive riding or deep sand, range may be closer to 62 miles (100 km). Eco mode can extend it past 81 miles (130 km) on flat hardpack.
How do I charge the battery, and can I charge it off the bike?
The 35Ah pack is detachable: unlock and slide it out. Connect the included smart charger to any standard household outlet (110V or 220V). Full charge in 3–5 hours. The BMS prevents overcharging and balances cells automatically.
Is the suspension suitable for heavier riders?
Yes. The fully adjustable hydraulic fork and shock allow spring preload, compression, and rebound tuning. Riders up to 331 lbs (150 kg) can set sag correctly. The linkage rear suspension progression handles big hits without bottoming out.
What maintenance does the electric drivetrain require?
The brushless motor is virtually maintenance‑free. Keep the chain or belt (depending on model) lubricated, check brake pads periodically, and inspect tire pressure before rides. No oil changes, air filters, or fuel stabilizers needed.
Is the bike waterproof? Can I ride in rain or puddles?
The electrical components are sealed to IP54 standards, meaning resistance to splashing water and dust ingress. Riding through rain or shallow puddles is fine, but submerging the motor or battery is not recommended. Always dry the bike after wet rides.

Academic / Thought-Provoking
Format: Paperback
They Were Her Property: White Women as Slave Owners in the American South is a powerful, eye-opening work that challenges long-held assumptions about slavery and gender in American history. Stephanie E. Jones-Rogers thoroughly dismantles the myth that white women were passive or marginal participants in the institution of slavery. Through meticulous research and extensive use of primary sources, including legal records, letters, and testimonies from formerly enslaved people—the book reveals that many white women were active, knowledgeable, and often brutal slave owners in their own right. What makes this book especially compelling is how it centers the voices and experiences of enslaved people to expose the economic, legal, and physical power white women wielded. Jones-Rogers shows that white women not only benefited from slavery but also enforced it, defended it, and used it to build wealth and social status. The writing is clear, authoritative, and accessible, making complex historical arguments understandable without oversimplifying them. This book is an essential read for anyone studying American history, slavery, race, or gender. It forces readers to confront uncomfortable truths and rethink narratives that have long softened or excused the role of white women in slavery. They Were Her Property is both academically rigorous and deeply impactful—a necessary contribution to honest historical understanding.

Remarkable analysis of slaveholding women in Antebellum America
Format: Paperback
Stephanie Jones-Rogers has provided us with a book that looks at the South's "peculiar institution" through a very different lens - the slaveholders/slaveowners, but this analysis looks at women that owned slaves, thus opening up a new avenue of study that I hadn't previously seen. Jones-Rogers offers a well written account that is rich in historical details. She demonstrates through vivid historical evidence that the women that owned enslaved people were primarily driven by economic motives, and that these women were just as demanding and could be just as harsh as the "typical" slaveowner image that has been crafted over the years. The book is organized thematically, and each chapter demonstrates the economic motivation behind slave ownership. The reader is offered views of everything from young children becoming slave owners when their parents "gifted" them an enslaved person, and how these young girls were taught that this was "property" that could be used as desired to how these female slaveholders would sell their slaves to meet their economic goals. All told, this is a fascinating book that uncovers a long ignored slice of Antebellum American history that makes the historiographical literature of pre-Civil War history much richer.

Poignant, truthful look at women as powerful, business-savvy, yet brutal slave owners
Format: Paperback
Women slave owners were the norm in the South, not the exception. They increased in numbers, stature, and power while the men were off fighting the Civil War. Women often owned the slaves, not the men and knew how to sign prenuptial agreements back then to insure they kept all their property (including slaves) upon divorce or death of their spouse. They traded and bought and sold slaves with business savvy that most men envied. And they could be just as brutal towards their slaves. Ironically, it was the ownership of other people that empowered these women to not be bound to their husbands.

Good history, but not fun, engaging in popular literature.
Format: Paperback
The author is a very competent historian, and proves her points. She does so by stating each thesis and then reciting an exceedingly long string of supporting examples. Rinse and repeat. This is high quality, academic style history, but it’s not very engaging as popular literature. No one’s going to say “I couldn’t put it down.” That being said - I liked it! I learned a lot. Thanks.

Should be required
Format: Paperback
In my opinion, this book should be required reading in high school/college history classes. It’s so important to learn accurate history when it comes to slavery and this book does that. White women played a larger role than we are taught. Please give this a read!
