Overview
A dual motor electric bike combining for a 6000W peak output and a claimed 50 mph top speed, built around a large 60V 35Ah (2100Wh) battery rated for up to 150 miles in assist mode. It targets off-road and hunting use on 24 inch fat tires.
A key-lockable throttle is meant to stop accidental starts and deter theft when parked, and riders can switch between a moderate mode for shared paths and a higher output mode for private or off-road terrain. Dual hydraulic brakes and a 6061 aluminum frame with full suspension back up the power, and the bike ships 90 percent assembled with a 1 year warranty.

Performance notes
The two 3000W peak motors combine for 200 Nm of torque and a rated 40 degree climbing angle, with dual hydraulic brakes providing stopping power at speed. Two selectable power modes let riders dial output down for neighborhoods and up for closed or off-road terrain.
