21/18 wheel setup
The 2026 Stomp Haywire is a serious electric dirt bike built for riders who want proper off-road performance, instant electric drive and a full-size enduro feel. With 21kW peak power, 28hp output and huge rear-wheel torque, the Haywire is designed for hard trail riding, technical climbs, jumps, wheelies and high-performance off-road use.
Instant 21kW electric power
At the heart of the Haywire is a PMSM hairpin motor delivering 28hp and up to 720Nm of rear-wheel torque through a 520 chain final drive. Power is instant, quiet and responsive, giving the bike a strong, controlled feel whether you are climbing, accelerating out of corners or riding tight technical sections.
74V 50Ah quick-change battery
The 74V 50Ah NCM lithium battery uses Bosch automotive-grade cells and is designed for long-lasting performance. Stomp quotes up to 80 miles of range at 25mph, with an approximate charge time of 5.5 hours depending on charger, conditions and use.
New 2026 look with practical upgrades
For 2026, the Haywire gets a completely restyled design with custom plastics, integrated headlight, indicators and brake light. It is available in Black or White and has a bold, modern look that suits both enduro-style riding and supermoto-style builds.
Fully adjustable Fastace suspension
The chassis uses a dual-wing cage chromoly frame with fully adjustable Fastace suspension front and rear. The 880mm front suspension and adjustable rear shock setup are designed to give the bike stability, control and confidence across rough ground.
Confident braking and 21/18 wheel setup
The Haywire uses twin-piston calipers with a 270mm front disc and 240mm rear disc, giving controlled braking performance for serious off-road riding. The 21-inch front and 18-inch rear wheel setup, paired with soft-compound enduro tyres, gives the bike a proper dirt bike stance.
