Stomp Haywire Dirt Bike

The Stomp Haywire is a high-performance electric enduro bike built around usable torque, balance, and precise control rather than headline peak horsepower. With a PMSM hairpin motor delivering 28 hp and up to 720 Nm of rear-wheel torque, it’s designed to pull hard out of corners, climb confidently, and stay composed when the terrain gets rough. A full-colour TFT display keeps ride data clear at a glance, while Reverse and Cruise Control add real-world practicality for tighter spots and longer stretches. 

Power comes from a 74V 50Ah (5C) quick-change lithium battery, with a quoted range of up to 129 km at 40 km/h and a charge time of ~5.5 hours. Four riding modes (Eco / Trail / Sport / Turbo) let you tailor speed and response (listed up to 96 km/h in Sport/Turbo), and the drivetrain runs through a gearbox and 520 chain to the rear wheel, backed by IP66/IP67 water resistance. The chassis pairs a dual-wing cage steel frame with an alloy swingarm, fully adjustable Fast Ace suspension front and rear, 21/18 off-road wheels, and strong braking hardware (270 mm front / 240 mm rear discs) to match the bike’s pace.
