AM120

The F18 2.0 is the second generation of HappyRun's mid-drive dirt bike, built around a 6000W peak motor that puts out 245 N·m of torque. That is enough to lift the front wheel on demand and hold 46 mph on open ground, with a 60V 27Ah battery behind it for up to 60 miles between charges.

Three features separate it from the original F18. A magnetic kill switch cuts motor power the moment you come off the bike, so a fall does not leave a running machine. An NFC card unlocks the color display with a tap, which keeps the bike secure without a key. And R-Turn reverse assist lets you back out of a rut or a tight corner by holding the R button and rolling the throttle.

The chassis is full suspension front and rear, running a hydraulic fork and a hydraulic-plus-spring rear shock, with hydraulic brakes on 190mm discs at both ends. Tires are 70/100-17 front and 90/100-14 rear on a frame that fits riders from 3'11" to 6'1" and carries up to 300 lbs.
