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
Motor
3.7kW BLDC
Transmission
2 speed planetary
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.
Frame & Swingarm
Construction Type
Monocoque
Material
4130CrMo Alloy
Warranty
2 Years
The longer wheelbase and stretched out the cockpit make for a more comfortable riding position than the Gen 1 models and minimise arm and leg fatigue when cranking on the pedals with throttle wide open.
We also dropped the C of G slightly and added some forward weight bias to help maximise traction and keep the front wheel planted as you steer with laser guided precision through tight and twisty turns.
To ensure that the F-37’s frame and swingarm withstand the test of time, we’ve applied the same zinc rich coating and hard wearing powdercoat layer as all of our Legacy models, allowing us to once again back it up with our lifetime frame warranty.
Battery
Capacity
1.5kWh
Range

Charge Time
2 hours
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 3 selectable power modes (Eco, Sports & Competition), riders have the option of a short, hard sprint or can allocate the whole day to exploring.
A 2-hour recharge time from a standard 110/240V outlets minimises down time maximises ride time when those vital electrons start running low.

Glass Filled Nylon
Controller Shield
Pressed Aluminium
Dropper Post
80mm Travel
For those who like to accessorise, the F-37 comes with a range of options protect you and your bike and to help you go fast.
While blasting through mud holes and puddles is one of our favourite past times, there's nothing worse than a face full of mud blocking your vision right when you need it. Made from super tough glass filled nylon, these high grade fenders are designed to take a beating just like the rest of your bike.
Our customised controller protectors are designed to take the impact from logs and rocks before your precious controller does. As an added bonus, the controller shield also acts as an air scoop to bring cold air in and force it around the controller's heat sinks to help keep things cool when you're out there breaking a sweat.
Changing terrain requires a change in seating position and that transition is now made easier with the new dropper seat post option allowing you to change from cruise to attack mode with just a flick of a lever.
