Stomp Haywire Electric Enduro Bike — 21kW, 720 N·m
The Stomp Haywire is a high-performance electric enduro bike built around usable torque, balance and precise control rather than headline horsepower. A PMSM hairpin motor delivers 28 hp (21 kW) and up to 720 N·m of rear-wheel torque, so it pulls hard out of corners, climbs confidently and stays composed when the terrain gets rough. A 74V 50Ah quick-change battery gives up to 129 km of range, four ride modes and a full-colour TFT display round out a genuine full-size enduro. Available now at Inner City Scooters, Dublin, Ireland.
Full-size enduro performance, electric drive
The Haywire is built to ride like a proper enduro bike. Its PMSM hairpin motor focuses on usable, controllable torque — up to 720 N·m at the rear wheel — rather than just peak power, so it climbs and accelerates with confidence. Four ride modes (Eco, Trail, Sport, Turbo) tailor the power and a top speed of up to 96 km/h, while Reverse and Cruise Control add real-world practicality. The power runs through a gearbox and 520 chain, backed by IP66/IP67 water and dust resistance.

Four ride modes + practicality
Eco, Trail, Sport and Turbo modes tailor speed and response (up to 96 km/h), while a full-colour TFT display, Reverse gear and Cruise Control add genuine real-world usability.
Fully adjustable Fast Ace suspension
Fully adjustable Fast Ace forks (Ø51/Ø43) and rear shock, on a dual-wing cage 16Mn steel frame with an alloy swingarm, deliver real enduro composure on rough terrain.
Strong braking & 21/18 wheels
Hydraulic disc brakes with a 270 mm front and 240 mm rear rotor, paired with full-size 21″ front / 18″ rear off-road wheels, give serious stopping power and grip.
IP66/IP67 weatherproofing
An IP66/IP67 water and dust resistance rating means the Haywire is built to handle wet, muddy and dusty trail conditions with confidence.

FAQ about the Stomp Haywire
Is the Stomp Haywire road-legal in Ireland?
No. The Haywire is a high-performance electric enduro bike (21 kW, up to 96 km/h) supplied for off-road and private-land use only. It is not type-approved, taxed or registered for public roads, so it must not be ridden on public roads, footpaths or cycle lanes in Ireland. Ride only on private land or sanctioned off-road areas with permission.
How powerful is it really?
It produces 28 hp (21 kW) peak and up to 720 N·m of torque at the rear wheel. Stomp has tuned the Haywire for usable, controllable torque — strong drive out of corners and confident climbing — rather than just a high peak number.
What range and charge time can I expect?
The 74 V 50 Ah battery has a quoted range of up to 129 km at a steady 40 km/h; real-world range depends on rider weight, terrain, mode and pace. A full charge takes around 5.5 hours, and the quick-change battery makes swaps fast.
What suspension and brakes does it have?
Fully adjustable Fast Ace forks and rear shock on a dual-wing cage steel frame with an alloy swingarm, plus hydraulic disc brakes (270 mm front, 240 mm rear) and full-size 21″/18″ off-road wheels.
Who is it suitable for?
It's a full-size electric enduro machine for experienced, confident riders, with a 920 mm seat height and 110 kg dry weight. Use Eco/Trail modes to ease in, and always wear full protective gear.
Can it handle wet and muddy conditions?
Yes — with an IP66/IP67 water and dust resistance rating it's built for genuine off-road use in wet, muddy and dusty conditions. Avoid full submersion and jet-washing, and dry it down after wet rides.
