Born from the heritage of Bakcou's flagship Mule, the Mule Jager SD takes everything riders love about the original workhorse and elevates it with a precision Germanengineered Rohloff internal gear hub. This sealed 14speed hub provides a huge 526% gear range and lets you shift through all 14 gears without pedaling, so you can drop into a lower gear even while standing still on a steep hillside. Because the gears are enclosed, there's no derailleur to catch on brush or break in rugged terrain. Paired with Bafang's ultrapowerful M620 middrive motor (750/1000 W)-often called the "diesel engine" of ebike motors-the Jager churns out up to 160 Nm of torque and 1 500 W peak power, giving you seamless, maintenancefree shifting and hillclimbing muscle for heavy loads.A 52 V 20 Ah battery powers the system, and our modular rack lets you add an extra 15 Ah or 20 Ah battery to double the capacity, up to 40 Ah total, eliminating range anxiety on long hunts and multiday expeditions. Built around the Mule's aircraftgrade 6061aluminum frame with a patented rear rack, the Mule Jager SD balances strength and agility. Its inverted 120 mm airfork suspension and shockabsorbing seat post smooth out rocky trails and washboarded dirt roads, while 24inch or 26inch fat tires provide unrivalled traction on mud, sand and snow. Fourpiston hydraulic disc brakes deliver confident stopping power, and wide, skidproof pedals offer secure footing even with heavy boots. An integrated stem display with Bakcou's OnDemand Program lets riders choose between Class 1, Class 2, or Class 3 modes, and Bakcou Connect technology (free for the first year for Mule models) provides remote security, tracking and diagnostics via smartphones. With the Mule Jager SD, you get the legendary power and range of our Mule plus the effortless shifting, durability and low maintenance of a Rohloff hub-everything you want and everything you didn't know you needed.
