Suspension on the WANDLER Electric Scooter: Shock Absorbers, Swingarm, and Riding Comfort Explained

The suspension of an electric scooter has several tasks: it should absorb road bumps, provide stable vehicle guidance, and ensure a controlled riding experience. On the WANDLER electric scooter, shock absorbers, the swingarm, mounts, screw connections, and tires work together for this purpose.

This article explains the basic function of the suspension on the WANDLER electric scooter. If you want to know specifically whether an upgrade to hydraulic shock absorbers is worthwhile, you will find a separate article on this: Are hydraulic shock absorbers worthwhile?

What is the purpose of suspension?

The suspension ensures that road bumps are not transmitted unfiltered to the rider, frame, and vehicle body. It also helps the wheels maintain contact with the ground and keeps the vehicle controllable during riding, braking, and steering.

This is not just about comfort. Too soft a suspension can cause the vehicle to sag significantly when loaded, bottom out more quickly, or feel spongy. Too stiff a suspension, on the other hand, can feel less comfortable for lighter riders. The correct tuning is therefore always a compromise between stability, load capacity, and riding comfort.

Standard Suspension for Everyday and City Traffic

WANDLER electric scooters are factory-tuned for the typical use case of a robust electric scooter: city traffic, commutes, paved roads, courtyards, campsites, and short to medium everyday rides.

The requirements differ significantly from a full-fledged off-road vehicle or off-road motorcycle. While particularly long suspension travel and large shock reserves are required off-road, the electric scooter primarily focuses on a robust, low-maintenance, and everyday-suitable design.

Why does the suspension feel different depending on the rider?

The riding experience is not solely determined by the shock absorber. Several factors influence whether a scooter feels more comfortable, firm, or hard:

A lighter rider puts less stress on the rear shock absorbers. As a result, the rear sags less, and the suspension can feel firmer. With higher rider weight or additional load, more suspension travel is used, which can make the riding experience feel different.

Rear Shock Absorbers: Why the Rear is More Stressed

On an electric scooter with a seat, a large part of the load is located at the rear. The rider, seat, battery, rear frame, and potential load mainly act on the rear suspension. Therefore, the rear shock absorbers must provide more carrying and support work than the front fork.

The rear suspension is therefore deliberately designed for stability. It should guide the rear, absorb road bumps, and offer sufficient reserves for higher loads.

The front suspension works differently from the rear

The front suspension has a different task. It guides the front wheel, absorbs steering and braking forces, and compensates for minor unevenness. At the same time, the front axle usually carries less continuous load than the rear in normal driving operation.

Therefore, the front and rear wheel suspension differ technically and in their tuning. At the rear, load capacity and stability are paramount. At the front, the focus is more on steering precision, guidance, and controlled response during braking.

Why spacers are used at the rear swingarm pivot point

At the rear suspension or swingarm pivot point, stepped spacers are used in certain WANDLER model versions. These components enable the necessary rotational movement of the swingarm and are adapted to the intended use of the vehicle.

Ball or roller bearings are primarily used where components continuously rotate at high speeds, for example, on wheels. The swingarm pivot point, on the other hand, does not operate at high speeds but only moves within a limited angular range.

For this application, a robust spacer construction can be a simple, durable, and low-maintenance solution.

Robust Solution for the Intended Purpose

The use of stepped spacers is not an unusual design. Similar technical solutions can also be found in various two-wheelers, scooters, ATVs, and simple utility vehicle designs where robustness, easy maintenance, and reliable function are more important than particularly complex bearing technology.

The nuts are designed with non-metallic locking inserts to prevent loosening. The tightening torque can be adjusted so that the rear swingarm remains movable and is simultaneously securely guided.

Not a design flaw, but a deliberate technical solution

The fact that a classic bearing design is not used at this point does not automatically imply a design flaw or a safety issue. The crucial point is that the design matches the vehicle's intended use and is correctly assembled.

When developing and selecting technical solutions, several factors are considered: area of application, load, maintenance effort, costs, spare parts supply, and market feedback. Therefore, individual technical details may evolve depending on the model version.

When an inspection is advisable

If the rear swingarm has unusual play, makes noises, or the suspension is not working properly, the vehicle should be inspected. This applies regardless of whether standard or hydraulic shock absorbers are installed.

In this case, we recommend an inspection by a specialist workshop or the WANDLER service. In particular, the screw connections, spacers, shock absorber mounts, swingarm, and the general condition of the rear suspension should be checked.

Conclusion

The suspension of the WANDLER electric scooters is designed for the intended everyday use. It should be robust, stable, and low-maintenance, while offering sufficient reserves for rider weight, load, and various surfaces.

The design with a rear swingarm, shock absorbers, and stepped spacers is a technical solution for city traffic, commutes, and normal everyday roads. Those who prioritize comfort, adjustability, and more controlled damping behavior can additionally consider an upgrade to hydraulic shock absorbers.
