About the F-37

When your trail riding needs elevating to new heights, the F-37 is the weapon of choice. Offering Stealth’s renowned hybrid-electric drivetrain with an ultra-lightweight Schlumpf two-speed transmission, the F-37 weighs just 40kg, and is propelled by a 3.7kW motor. Maximising rider control is a 200mm rear wheel travel Stealth frame, with cockpit aesthetics modelled for ultimate manoeuvrability, whether in flight or glued to the trail.

  • Top Speed: 60km/h
  • Range: up to 100km
  • Noise @ 50km/h: 65dB

With two performance modes on offer, the F-37’s top speed can be limited to 25km/h, or fully unleashed to serve up a 60km/h top-end.

  • Peak Power: 3.7kW (3700 Watts)
  • Motor Type: Brushless DC
  • Battery Type: LiIon
  • Battery Capacity : 1.5kWh
  • Recharge Time : 3 hours
  • Charge : Standard 110-240V

The F-37’s reduced performance mode limits power to 250 Watts, while its full combat mode cranks things up to 3700 Watts (3.7kW).

The F-37’s brushless DC motor puts out a staggering 3700 watts of peak power, accelerating up to 60km/h in total silence. The electrical output is multiplied when combined with your own pedal power, which is driven through a two-speed internal gearbox.

  • Front Travel (DNM USD-8 Standard): 200mm
  • Front Travel (MRP Groove 200 Upgraded): 200mm
  • Regenerative Braking System

Keeping it all in check are Magura MT5 hydraulic disc brakes (upgradable to MT7 at your request).
