The Haywire replaces a petrol trail bike with a quiet, high-output electric drivetrain in a traditional motocross-style chassis. Its PMSM hairpin motor delivers strong low-speed response and sustained acceleration through technical terrain, four ride modes with regen and reverse tailor the output to the terrain and the rider, and the hot-swappable battery makes charging between rides more flexible.
The dual-wing cage chromoly frame carries fully adjustable FastAce suspension front and rear, with 245 mm of fork travel and a linkage rear end, and a 520 chain final drive keeps it compatible with traditional off-road drivetrain setups. Twin-piston hydraulic brakes on 270 mm and 240 mm rotors provide consistent stopping, and an IP66/IP67 rating supports riding in wet conditions.
