Scorpion fs 20 - the fully suspended, foldable Trekking-trike

Trike Dynamics Comfortably Balanced: Scorpion fs 20
Discover HP Velotechnik's Compact Full-Suspension Foldable Touring Trike

It’s good to know, that even if things get rough ahead of you, you can still stay laid back and relaxed. When developing the award-winning design of the Scorpion fs 20 foldable touring trike, HP Velotechnik’s engineers used the latest chassis technology from the automotive sector to provide the most comfortable full suspension for your ride. But they did not compromise by simply using retro-fit solutions on existing frames:

The whole vehicle was developed from scratch to incorporate an impressively sensitive full suspension in a sleek and lean design delivering superior performance. The wishbone axle geometry and HP Velotechnik’s unique Stabilizer System, with its anti-roll bar integrated into the frame design allow full use of the ample suspension travel. It is finely tuned to perfectly respond to the forces of the road. The low seat and far higher pedal position highlight the agile adult trike’s sporty character.

You can feel the benefits of this masterpiece of finest German trike engineering immediately when cutting your first corner: enjoy a perfect synthesis of outstanding road-holding and a maximum of “Fahrvergnügen.”

The Full Suspension Chassis
The Roughest Road Becomes an Exhilarating Ride
Potholes, cobblestones, gravel roads: the condition of your way ahead can be shocking indeed. From now on, you are going to look forward to riding those sweet little challenges. Once you want to leave the beaten track, you need a quick responding suspension, stable road holding, precise steering, and an optimum of steadiness. Now, the Scorpion fs 20 is your perfect choice.

The comfortable MacPherson front suspension has 6 cm (2.4 inches) of travel and uses a reliable spring and elastomer system. The suspension struts are supported on the far end of the frame’s rigid, large-diameter crossbar close to the wheel. The adjustable wishbones are equipped with maintenance-free bearings.

With this design, our engineers were able to keep unsuspended masses at a minimum, achieving a rapidly responding front suspension action with an astonishingly low weight from 17,5 kg for the fully suspended recumbent touring trike Scorpion fs 20. The suspension preload is adjustable. By exchanging the steel springs and varying the parallelly positioned MCU-elastomer / spacer stack, you can adjust the suspension characteristics, stiffness, and progression to match your personal riding style and needs.

The Scorpion fs 20’s most unique feature is the beefy wishbone andstabilizer bar system under the cruciform frame. This stops the trike from rolling in corners while preserving its suspension movement. Control at the extreme limits is noticeably improved and tipping safety significantly increased. The AntiDive kinematics prevent the negative dive effects on braking.

The design of the camber and track geometry ensures that the steering mechanism offers straight-line stability over the entire suspension travel and remains easily accessible and free from impairment when braking (brake steer) or traversing obstacles (bump steer). You can feel it immediately: in the precision of the steering, the sporty handling, and the direct feedback from the road.

The entire chassis is designed using our No Squat suspension design and transmits all of your drive energy to the road without any loss of power. In return, you enjoy complete comfort so that you can lean back and relax while dynamically accelerating, even on rocky roads.

This Great Trike Performs Fast Also When Folding Tiny for Transport

With the Scorpion fs 26, HP Velotechnik presented its first full-suspension speed trike with a smooth-running 26-inch rear wheel, that can be folded flat for transportation without the use of tools.

It only takes a minute to fold your Scorpion fs 26 in just a few simple steps into a space-saving package with dimensions of 123 × 83 × 62 cm (49 x 33 x 25"). If you remove the wheels as well, the dimensions reduce even further to a compact 93 × 74 × 54 cm (37 x 29 x 22"). Even with the luggage rack and fenders attached, the Scorpion fs 26 can still be folded up without removing the wheels. I And the chain? The chain rotates around its axis and otherwise reliably remains where it should be, guided by the flexible chain guard tubes.

The best part: When you unfold the trike, HP Velotechnik’s unique, self-locking folding hinge enables you to turn your excited anticipation into pure riding pleasure quickly!
