Industry-Leading Electrical Safety

UL 2849 Certified: This is the gold standard for eBike electrical systems. It means the entire drive train—including the mid-drive motor, computer, and charger—has undergone rigorous testing to prevent electrical failures, ensuring complete reliability when you are miles away from home.

UL 2271 Certified: This specifically covers the lithium-ion battery. It ensures the "heart" of your bike is protected against overcharging, short-circuiting, and impact, providing a safer charging and storage experience in your home or garage.

Meet your new ride:

60-80 Miles of Pedal Assist Range. A premium 48V, 20Ah (960 Wh) Samsung/LG battery powers your extended adventures and long-distance treks. Think of Watt-hours as being the size of your gas tank. (The average mid-range eBike has around 500 to 650 Wh).

28 MPH Max Speed

Watts with the Torque? The D5 Pro is propelled by a high-end Bafang mid-drive motor that serves up a massive, hill-flattening 120 Nm of torque. Combined with an advanced internal drive system for whisper-quiet, ultra-efficient operation, this heavy-duty power configuration means you can effortlessly conquer the steepest inclines, accelerate smoothly from a dead stop, and handle rugged terrain without breaking a sweat.

Unlike standard e-bikes, the D5 Pro utilizes a sophisticated torque-sensing system. By measuring exactly how hard you are pedaling rather than just how fast, the mid-drive motor delivers a remarkably natural, lag-free power boost that perfectly mirrors your own effort. This optimizes battery efficiency—yielding an impressive 60 to 80 miles of pedal-assist range across 5 levels of PAS.

Out of the box, the bike is programmed with a default maximum speed of 20 MPH, but it can be easily adjusted to achieve a top speed of 28 MPH. This flexibility allows you to seamlessly configure the electronics to match your local riding and trail laws, giving you the ability to switch the bike between Class I or Class III operational modes.

What Class Rating does the D5 Pro All-Terrain have and why should I care?

This premium eBike offers the ultimate flexibility, capable of switching between Class I, Class II, and Class III modes. While it ships as a Class II, you can easily change it through the colorful, centrally mounted LCD control panel.

Understanding the Class Ratings: Why Versatility Matters

Class I (Pedal Assist Only, 20 MPH): The motor provides assistance only when you are pedaling and ceases to provide help once you reach 20 MPH. This mode is widely accepted on multi-use public land paths, mountain bike trails, and state parks that strictly prohibit throttles.

Class II (Throttle & Pedal Assist): This is the "out of the box" setting. The bike includes a throttle that can propel you up to 20 MPH without any pedaling required, perfect for effortless cruising or getting a boost when hauling heavy gear from a standstill.

Class III (High Speed, 28 MPH): This unlocks the eBike's top speed of 28 MPH via pedal assist. It is the ideal setting for commuting on city streets or covering long distances quickly across open gravel roads and double-tracks.

Understanding local and state ebike regulations is essential because laws vary significantly regarding where different class types are permitted, and staying informed ensures you can enjoy the full range of riding freedom while remaining legally compliant and safe on every road and trail.

Battery and Charger

The D5 Pro is powered by a massive, high-performance 48V 20Ah battery pack built with premium, automotive-grade Samsung or LG 21700 cells. Engineered for extreme safety, reliability, and longevity, the entire battery pack is officially UL 2271 certified. To minimize your downtime between rides, the system includes a powerful smart fast charger, allowing you to quickly replenish the high-capacity cells and get back out on your next journey with minimal waiting.

Shimano 9-Speed Gears

The D5 Pro features a high-performance Shimano 9-speed drivetrain engineered for smooth, precise, and reliable shifting across varied terrain. Paired perfectly with the high-torque mid-drive motor, this gearing configuration provides a wider mechanical range to efficiently tackle incredibly steep climbs and maintain a comfortable pedaling cadence at top speeds. The system features an authentic Shimano rear derailleur, a matching Shimano shift lever, and an e-bike-rated chain built to handle the incredible torque output of the mid-drive system without skipping a beat.

Hydraulic Disc Brakes

The D5 Pro is equipped with a premium Tektro hydraulic disc braking system engineered for maximum stopping power and precise, modulated control. This setup pairs oversized rotors with superior heat dissipation, offering exceptional braking leverage under heavy loads or high speeds. The system is operated via durable aluminum alloy brake levers that feature an integrated electronic power cutoff mechanism. The moment you pull the levers, power to the motor is instantly disconnected, ensuring rapid, safe, and reliable stops in any weather or trail condition.

26" x 4" Fat Tires

The D5 Pro comes factory-equipped with premium 26" x 4.0" all-terrain fat tires. Engineered specifically for high-performance off-roading, these tires feature an aggressive tread pattern designed to bite deep into loose terrain, snow, sand, and mud while maintaining a smooth rolling resistance on hardpacked surfaces and pavement.

Strong and Lightweight Aluminum Alloy Frame

Built to handle the demands of rugged exploration and urban commuting alike, the D5 Pro is engineered around a premium, high-strength 6061 Aluminum Alloy frame. This robust chassis features a classic high-top-tube architecture, creating a closed triangle geometry that maximizes structural strength, frame stiffness, and provides the perfect mounting baseline for gear bags, water bottle cages, and cargo accessories. The frame provides a rock-solid, stable foundation that ensures predictable handling, a heavy-duty payload capacity, and crisp responsiveness on every single journey.

Suspension

The D5 Pro features an advanced front suspension system engineered to deliver top-tier comfort and stability across rugged trails and bumpy city streets alike. Up front, a high-performance adjustable suspension fork with lockout absorbs heavy impacts from potholes, roots, and ruts, drastically reducing jarring vibrations. Working together with its rugged 4-inch fat tires, this setup maximizes ground traction, keeps you in total control, and provides an ultra-cushioned, floating ride no matter how wild the terrain gets.
