Haywire
65 MPH · 80 mile range
By the numbers
When we got our hands on the Haywire, our verdict was immediate: one of the highest quality e-moto we've seen, full stop. Every component is dialed, every detail intentional. This is a bike engineered by riders who care about the ride, not the spec sheet.
Hot-swap battery with automotive-grade cells
74V 50Ah pack using Bosch automotive-grade cells — the same quality standard as full-sized electric vehicles. 80 miles per charge, 5.5 hours wall-to-full on standard outlets. Pull the depleted pack, drop in a fresh one, keep riding. Zero downtime for serious trail days.
PMSM hairpin motor with 720 Nm of torque
28 horsepower, 21 kW peak, and a staggering 720 Nm of torque at the rear wheel. Four selectable ride modes — Eco, Trail, Sport, Danger — with regen braking and reverse built in. IP67 water resistance means the motor is sealed for weather, river crossings, and whatever else the trail throws at it.
FAST ACE suspension, fully adjustable
880mm FAST ACE fork with 245mm of travel up front, 442mm shock out back. Compression and rebound adjusters positioned so you can tune on-the-fly between runs. Developed and dialed by Stomp's in-house engineers for real-world terrain — not a catalog setup.
Twin-piston brakes at both ends
270mm front rotor and 240mm rear, two-piston calipers front and back, both operated by handlebar levers the way they should be. Serious stopping power scaled to the bike's 65mph top end, with lever feel that matches gas-powered dirt bikes.
The highest quality e-moto we've put our hands on
We have has torn down, rebuilt, and ridden a lot of e-motos. We know where the corners get cut, the cheap connectors, the underspec'd suspension, the frames that flex when they shouldn't. When the Haywire arrived, we looked it over end to end and then took it out. Our verdict was immediate.
A chromoly dual-wing cage frame with an aluminum swingarm and a real bash guard. FAST ACE suspension with on-the-fly adjusters. Twin-piston calipers front and rear. A hot-swappable 50Ah battery using Bosch automotive-grade cells. A PMSM hairpin motor sealed to IP67. Full LED lighting integrated cleanly into redesigned plastics. Nothing feels like a compromise.
We carry it because when riders ask us "what's a real e-moto that's actually worth the money," this is the most honest answer we can give right now.
A serious bike for riders who want the real thing
The Haywire is built for riders who already know what they want from an e-moto. Trail miles, technical climbs, street sessions, supermoto builds — it does all of them without feeling undergunned. 28 horsepower, 720 Nm of rear-wheel torque, and 65 mph top speed give it genuine performance range.
Four ride modes mean you can dial it back for casual rides or unlock the full output when the terrain calls for it. The hot-swap battery system is a huge advantage for anyone planning long days or back-to-back rides — no sitting around waiting to recharge.
Not the right bike for a true beginner or anyone looking for an entry-level learner — this is a serious performance e-moto with the power and geometry to match. If you're new to riding, ask us about the Phase I instead.
