The FREESKY Alaska Pro is a fat-tire electric mountain bike built around a 750W motor rated at 160Nm and a dual 48V 45Ah battery split between the upper tube (18Ah) and lower tube (27Ah). FREESKY claims 120-200+ miles per charge, roughly 2.3 times a typical single-battery eBike, with LG cells and UL 2271 TÜV certification. Full hydraulic suspension, 26-inch fat tires and dual 4-piston hydraulic brakes target rough terrain and heavy riders. It ships 85% assembled with a 24-month warranty on frame, motor, battery and controller. The trade-off is weight and complexity: two batteries and a big frame make it a handful to move and store, and the 20 mph limiter keeps it Class 2 rather than a speed bike.

The FREESKY Alaska Pro is an adult electric mountain bike with a 750W motor and a 6061 aluminum frame. It has full front and rear suspension and CST 26" x 4.0" fat tires. Dual 4-piston hydraulic disc brakes handle stopping, and the drivetrain is a 7-speed manual transmission.
Two removable 48V LG-cell batteries make up a 45Ah system: 18Ah in the upper tube and 27Ah in the lower tube. Both batteries are UL 2271 certified by TÜV and use a battery management system rated for 5000+ cycles. Range is up to 200 miles in pedal-assist level 5.
A smart LCD display and a FOC sinewave controller manage the bike, and it has keyless unlock. In the factory Class 2 mode, the bike is limited to 750W and 20 mph. For higher torque, press and hold the "O" button on the display: "20" is Class 2 mode and "64" is the higher-torque mode.
