- Charge : Standard 110-240V
Stealth’s® proprietary DC-1 display allows all Stealth owners to read real-time data and vital stats such as speed, battery consumption, range estimation and efficiency at a glance. It’s intuitive layout and easy to access menus create a use friendly experience for even the most novice riders.
In a world where efficiency and reliability means everything, Stealth’s solid state, digital inverter technology has absolutely no moving parts, eliminating the possibility of wear and tear.
Tried and tested, the F-37’s 1.5kWh lithium ion battery offers uncompromised safety and reliability on the trails taking you further, for longer. With a 3 hour recharge time, all Stealth customers are given the convenience of plugging in to any 110/240V household outlet to stock up on those vital electrons.
Drive Train and Technology
Using the very latest in brushless DC hub motor technology, the F-37’s 3.7kW powerplant accelerates from 0km/h to its terminal velocity in virtual silence. Having only one moving part, the F-37’s high efficiency, direct drive powerplant requires next to no maintenance giving it a huge advantage over its petrol/gas powered counterparts.
Pilots requiring a little more acceleration can further boost performance with the a high torque surge of pedal power transmitted via the 2 speed planetary drive transmission, not only increasing acceleration but producing significant range gains.
- Front Travel (DNM): 200mm – Standard
- Front Travel (MRP): 200mm – Upgrade
- Rear Travel (DNM): 200mm
Standard issue on the F-37 is DNM’s USD 8, 200mm travel front forks. Tuned and spec’d by the Stealth team, this is a great all round package for riders who want to mix their riding styles. Being air adjustable makes it suitable for a wide range of rider weights within minutes.

- Magura MT5 – Standard
- Magura MT7 – Upgrade
- Regenerative Braking System – Standard
When it comes to stopping power, the standard issue German made Magura MT5’s offer 4 piston hydraulic brake calipers for German stopping precision with no more than 2 fingers on the levers.
For pilots in that top 10% who like to take it to the limit, we also offer an upgrade to the Magura MT7s which provide on tool less reach and bite point adjustment allowing you to fine tune your brakes on the fly. Performance is further enhanced with the MT7’s monoblock brake pads significantly improving heat dissipation while increasing bite on the leading edge.
When slowing down or coasting, pilots can also activate the Regen braking, which recovers kinetic energy feeding it back into the battery pack, further enhancing range and ride time.
