Engineered for the Ride
Precision Motor Integration
The 250W rear hub motor delivers seamless torque application with minimal noise. Its clever power mapping responds naturally to your pedaling cadence, providing up to 20 mph (32 km/h) of pedal-assisted speed on demand. The system is optimized for energy efficiency, reducing battery consumption on flat stretches while supplying ample grunt on challenging ascents.
High-Capacity Lithium Power
A 36V 20Ah lithium-ion pack provides a real-world range exceeding 37 miles (60 km) on a single charge, depending on terrain, rider weight, and assist level. The battery management system safeguards against overcharge, deep discharge, and temperature extremes. Replenish energy in approximately 3 hours with the included charger, ready for your next outing.
Forged Aluminum Frame
The lightweight yet rigid aluminum alloy frame absorbs trail vibrations while maintaining precise steering feedback. Its geometry is tuned for confident handling across mixed surfaces, with a low standover height for easy mounting and dismounting. Corrosion-resistant finish ensures lasting aesthetics through seasons of use.
Mechanical Disc Braking
Equipped with front and rear mechanical disc brakes, the HKM-390035 delivers consistent, powerful stopping performance in wet, muddy, or dusty conditions. The large rotors dissipate heat effectively, reducing fade on long descents, while the ergonomic levers provide precise modulation for confident control.
7-Speed Precision Shift
A wide-ratio 7-speed cassette paired with a reliable derailleur gives you the right gear for every situation. Click through ratios effortlessly while climbing or sprinting, with indexing that stays accurate ride after ride. The system requires minimal maintenance and is widely serviceable.
27.5″ × 2.1″ All-Terrain Tires
The 27.5-inch diameter provides an optimal balance of rollover capability and agility. The 2.1-inch width offers a generous contact patch for traction on loose gravel, hardpack, and pavement, while still maintaining low rolling resistance. Durable tread compound extends tire life across varied landscapes.
Integrated Mudguards & Reflectors
Full-length front and rear mudguards shield you from spray and debris, keeping your clothing clean when the trail gets messy. High-visibility reflectors enhance your presence in low-light conditions, and the sturdy kickstand offers convenient parking anywhere.
Thoughtful Cockpit & Controls
An intuitive handlebar layout places the display, shifters, and brake levers within easy reach. The clear LCD readout shows speed, battery level, and assist mode at a glance. Ergonomic grips reduce fatigue on longer journeys, so you can focus on the trail ahead.
