At the heart of the Haywire is a high-efficiency PMSM hairpin motor delivering an impressive 28 hp and up to 720 Nm of rear-wheel torque — enough to launch out of corners and conquer steep, technical terrain with confidence. Coupled with a 50 Ah quick-change lithium battery built on Bosch automotive-grade cells, this electric dirt bike offers reliable power delivery and a claimed range that keeps you exploring further between charges.
No two trails are the same, and the Haywire is built to adapt. With four selectable riding modes — Eco, Trail, Sport, and Turbo — riders can fine-tune throttle response and power output for the terrain at hand. Whether you’re easing into a scenic ride or pushing hard on challenging tracks, these modes help maximise both efficiency and performance. Regen braking and a handy walking reverse feature add real-world practicality to every ride.
Engineered for off-road agility, the Haywire’s custom Fast Ace fully adjustable suspension keeps the bike composed over rough ground. With adjustable front and rear damping, you can dial in comfort or performance depending on your riding style. The robust chassis, dual-wing cage frame and quality braking system with oversized front and rear discs ensure that every ride feels planted and controlled, whether you’re navigating tight switchbacks or powering down faster sections.
From its full-colour TFT display, giving you all essential riding info at a glance, to its rugged off-road tyre setup and IP66/IP67 water resistance, the Haywire is as ready for unpredictable weather and terrain as you are. With striking aesthetics available in multiple colourways and options to customise for supermoto style, this electric enduro bike isn’t just about performance — it’s about expressing your passion for riding.
