AM120

The G100 Pro is the fastest and heaviest machine in the line, styled like a café racer and quick enough to ride like a small motorcycle. A 72V system peaking at 6000W takes it to 50 mph, and the dual battery, 18Ah on top and 15Ah below, gives up to 78 miles between charges.

It is the heaviest and highest-capacity bike HappyRun builds: 159 lbs with a 400 lb payload, on a carbon steel frame with full suspension and an upgraded adjustable aluminium fork. Braking is hydraulic with power cut-off, running a 180mm front and an oversized 203mm rear rotor.

The cockpit uses NFC card unlock and a large sunlight-readable LED display with a sun visor. A half-twist throttle and five levels of pedal assist let you choose how much work you do, and a speed limit function caps it at 28 mph when you want a calmer ride.
