This listing is a two-bike package containing two Eunorau FAT-HS / Hunter X8 electric mountain bikes — a convenient option for couples, families, or riding partners who want a matched pair. Each bike ships as a complete, individually boxed unit, and frame size (17-inch or 19-inch) is chosen separately for each of the two bikes in the package.

Every FAT-HS / Hunter X8 in the bundle is built around a 48V 1000W Bafang M615 mid-drive motor with 160 Nm of torque and cadence-sensing pedal assist, mounted in an aluminum alloy frame with front and rear suspension. A 48V 15Ah battery provides the base range, and each frame supports an optional second battery for riders who want extended range on longer trips.

Each bike also includes 26 x 4-inch fat tires for traction across sand, mud, and snow, hydraulic disc brakes with a motor cutoff sensor, a 9-speed drivetrain, and an LCD display. Together, the two bikes in this package make it easy to outfit two riders with the same capable, all-terrain electric bike at once.
