STEALTH F-37, SUPERIOR DOWNHILL/AGILE COMMUTING
When your trail riding needs elevating to the next level, the F-37 is your weapon of choice. Commonly referred to as the B-52’s baby brother, the F-37 has the pace and agility to carve it up like no other. Offering Stealth’s renowned hybrid-electric drivetrain combined with the well-known Speed Drive two-speed transmission, the F-37’s simplicity is also its strength. Its long travel suspension package and ergonomically designed cockpit are modelled for ultimate manoeuvrability, whether in flight or glued to the trail.
The F-37’s torquey brushless DC hub motor and high power to weight ration accelerates pilots to speeds of up to 60km/h, leaving all competitors in its dust. Additional power can be transmitted to the ground via the 2-speed, internally geared bottom bracket to increase range, efficiency and acceleration. In economy mode with moderate pedalling, the F-37 pilots can expect a range of up to 100km (60 miles) on flat terrain. When competition mode is engaged, and the red mist comes down, a wide-open run on the trails will achieve up to 40km (25 miles) on a full charge. 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 mean 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. 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 a high torque surge of pedal power transmitted via the 2-speed planetary drive transmission, not only increasing acceleration but producing significant range gains.
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. For those looking to take their riding to the next level, we also offer the US made MRP Groove 200 fork as an upgrade option. Offering a super plush ride with lots of air and oil adjustability and technical backup from MRP’s headquarters in Grand Junction, Colorado, this option is very hard to pass up.
When it comes to stopping power, the standard issue German made Magura MT5’s offer 4 piston hydraulic brake callipers for German stopping precision with no more than 2 fingers on the levers. 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.
