How fast is the Stomp Haywire Enduro?
Stomp rates the Haywire Enduro at a 65 mph (105 km/h) top speed in Sport and Danger modes, from 21 kW (28 hp) of peak power out of the PMSM hairpin-construction motor and approximately 720 Nm of rear wheel torque, delivered for strong low speed response and sustained acceleration through technical terrain. Four selectable ride modes, Eco, Trail, Sport and Danger, let the rider tailor that output to the terrain and to their experience level, and the 520 chain final drive keeps the Haywire compatible with traditional off road drivetrain setups.
How do I charge the Stomp Haywire Enduro and how far does it go?
The Haywire Enduro runs a 74V 50Ah NCM lithium battery that is removable, so the pack can come off the bike to charge between rides instead of the whole bike going to the charger. Stomp rates the range at up to 80 miles (129 km) at 25 mph (40 km/h), and a charge from 20 to 100 percent takes 5.5 hours. The system carries an IP66/IP67 waterproof rating for riding in wet conditions.
Who is the Stomp Haywire Enduro for?
The Stomp Haywire Enduro is a full size e-moto built for enduro riding, trail use and off road exploration, in a traditional motocross style chassis layout for riders who want strong torque delivery in place of a petrol powered trail bike. The dual-wing cage steel frame is matched with fully adjustable FastAce front and rear suspension for stability across rough ground, and the 21 inch front and 18 inch rear wheels keep the familiar enduro geometry that experienced dirt riders expect. Hydraulic disc brakes handle the stopping, and the four ride modes mean a newer rider can start in Eco or Trail while a more experienced rider runs Sport or Danger on the same bike. It weighs 243 lb (110 kg) dry, with a 919 mm (36.2 in) seat height and a 220 lb (100 kg) rider weight limit. At GritShift we offer it in White, Black and Grey.
