Conquer Any Terrain With The Mule SD
Born from the heritage of Bakcou’s flagship Mule, the Mule SD takes everything riders love about the original workhorse and supercharges it. At its heart is Bafang’s ultra‑powerful M620 mid‑drive motor often called the “diesel engine” of e‑bike motors, which churns out up to 160 Nm of torque. This torque‑rich motor, paired with an 11‑speed SRAM NX drivetrain and removable thumb throttle, delivers the hill‑climbing muscle hunters and off‑road riders need. A 52 V 20 Ah lithium‑ion battery powers the system, and Bakcou’s modular rack lets riders add an extra 15 Ah or 20 Ah battery to double the range, up to 40 Ah total, eliminating range anxiety on long hunts and multi‑day expeditions.

Built around an aircraft‑grade 6061‑aluminum frame with a patented rear rack, the Mule SD balances strength and agility. Its inverted 120 mm air‑fork suspension and shock‑absorbing seat post smooth out rocky trails and washboarded dirt roads, while 24‑inch or 26‑inch fat tires (CST or Maxxis Minion) provide unrivalled traction on mud, sand and snow. Four‑piston Tektro HD E725 hydraulic disc brakes deliver confident stopping power, and wide, skid‑proof pedals offer secure footing even with heavy boots. An integrated stem display with Bakcou’s On‑Demand Program (ODP) lets riders choose between Class 1, Class 2, Class 3 modes, while Bakcou Connect technology (free the first year) gives remote security, tracking and diagnostic capability via smartphone.

FAQ

The Mule SD is powered by Bafang’s Ultra M620 mid‑drive motor, which is available in Class 1, Class 2, and Class 3 configurations. It produces up to 160 Nm of torque, plenty of hill‑climbing power for steep mountain trails and heavily loaded rides.

Yes. Bakcou’s On‑Demand Program (ODP) lets you configure the bike as a Class 1, Class 2, Class 3 or unlimited e‑bike via the integrated stem display. That makes it easier to comply with local regulations when riding on public land or trails.

Yes. Bakcou Connect technology (free for the first year) allows you to lock, track and monitor your bike’s health via a smartphone.

While not possible to give a precise single‑charge range for any bike because your mileage will depend on factors like terrain, elevation, rider weight, wind, temperature and the level of assist or throttle you use, we can offer a ballpark estimate: with a single battery most riders see around 40–60 miles of real‑world range, and with a dual‑battery setup you can extend that to over 100 miles. Think of these numbers as general guidance rather than guarantees because actual range will always vary based on how and where you ride.

For all of our ebikes, we stand behind your purchase with a one‑year limited manufacturer’s warranty. The warranty starts the day you receive your bike and covers major components like the battery, frame, motor, controller, wiring harness and LCD display. To activate your coverage, be sure to register your bike within 30 days of delivery; the warranty is valid only for the original owner and can’t be transferred. It protects you against manufacturing defects in materials and workmanship but doesn’t cover normal wear, misuse or modifications. If you ever have a problem, just reach out to our support team and we’ll guide you through the warranty claim process.

The Mule SD weighs about 77 lbs without the battery and roughly 90 lbs with the 20 Ah integrated battery. Bakcou rates the bike for riders up to 350 lbs plus gear. The sturdy 6061‑aluminum frame and 4 in‑wide fat tires support heavy loads and maintain stability on rough terrain.
