Stealth F-37
Single Track Slayer
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 2-speed transmission, the F-37’s simplicity is also its strength. Its long travel suspension package and ergonomically designed cockpit are modeled for ultimate maneuverability, whether in flight or glued to the trail.

Standard issue on the F-37 is Fast Ace, 180mm travel inverted 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. On the rear the F-37’s oil damped shock provides all the adjustment that you need with compression, rebound and preload adjustment all at your finger tips.
Speed and agility don't mean a lot without precise braking and the new F-37 has got that one in the bag. Coupled with the powertrain's regen braking system, there's arguably no e-bike on the planet that can stop like the F-37.
Fitted with the same 250mm brake rotors and mini-moto calipers as the B-52, brake fade is non existent. Those who have seen their rotors change colour after a mammoth downhill run will know exactly what we mean by "brake fade".
Drivetrain & Transmission

Gear Shifting
Paddle shift
Electromotive force is laid down by the F-37’s 3.7kW BLDC hub motor which, like the B-52 and H-52 has just one moving part transferring power to the ground. With over 10 years of development the F-37’s proven floating drivetrain not only prevents chain stretch, but reduces the need for clunky tensioners, significantly reducing wear and tear of unnecessary parts.
Shifting gears is now so much easier with the addition of new shift paddles to the Speed Drive's 2 speed crankset. The 1.65:1 gear ratio, and new paddle shifters just need a quick tap with your heel for a guaranteed a positive shift between high and low ratio at any time.
