Spain has become one of Europe’s most structured markets for electric scooters. For riders looking for a road-legal electric scooter, performance is only one part of the equation. A scooter must also meet Spain’s technical requirements, obtain the appropriate VMP certification, and comply with registration, insurance, equipment, and road-use rules.

The Ausom K20 VMP Electric Scooter and Ausom K30 VMP Electric Scooter are specifically designed for the Spanish market and are listed by Spain’s Dirección General de Tráfico (DGT) as certified VMP models. The K20 is listed under certificate B1155, while the K30 is listed under certificate B1156.

Although the two VMP e-scooters share several important specifications—including a single 1100 W peak motor, 48 V 13.5 Ah battery, up to 70 km claimed range, and a 20 km/h default top speed—their physical dimensions and suspension designs are different. Those differences can influence portability, stability, and comfort on different types of urban roads.

K20 vs. K30 at a Glance

The specifications above come from the respective Ausom product pages.

1. Ausom K20 VMP: A More Compact DGT-Certified Option

The Ausom K20 VMP is designed around a relatively compact folding format while still offering substantial equipment for everyday urban riding.

Its 1100 W peak single motor produces 24 Nm of torque, while the 648 Wh battery provides a claimed range of up to 70 km. The scooter has a default top speed of 20 km/h on its Spanish VMP configuration and supports a claimed 20% climbing ability.

One of the K20's defining characteristics is its size.

The unfolded scooter measures 1170 × 720 × 1330 mm and weighs 25.5 kg. When folded, its dimensions become 1170 × 720 × 515 mm.

That makes the K20 the smaller and lighter model of the two.

Its 520 × 185 mm deck and 720 mm handlebar provide a relatively generous standing area, while the folding structure makes storage and transportation easier.

K20 suspension: front fork + rear swingarm

The K20 uses the Ausom ShocFree® suspension system, combining a high-strength front fork with an adjustable rear swingarm suspension.

This arrangement provides suspension at both ends while maintaining a comparatively compact structure. Ausom positions the system for reducing vibration and improving stability on uneven pavement, rough streets, and everyday urban terrain.

For riders who frequently combine ordinary city streets with less-than-perfect pavement, the K20's suspension gives it more versatility than a basic rigid-frame commuter scooter.

2. Ausom K30 VMP: A Larger and More Substantial Platform

The Ausom K30 VMP uses the same fundamental power and battery configuration as the K20, but its chassis is larger.

It has a 1100 W peak single motor, 648 Wh battery, claimed range of up to 70 km, 20 km/h default top speed, and 20% claimed climbing ability.

The biggest difference becomes apparent when looking at the physical specifications.

The K30 measures 1250 × 720 × 1350 mm when unfolded, compared with 1170 × 720 × 1330 mm for the K20. Its folded dimensions are 1250 × 720 × 540 mm, while its net weight is 27.5 kg.

In other words, compared with the K20, the K30 is:

• 80 mm longer
• 20 mm taller
• 2 kg heavier
• 25 mm longer when folded
• 25 mm taller when folded

The handlebar width remains 720 mm, and both models use a 520 × 185 mm deck.

The K30 also has a higher listed maximum load of 147.5 kg, compared with 130 kg for the K20.

3. The Key Suspension Difference: K20 vs. K30

The suspension design is one of the most important differences between the two scooters.

K20

The K20 uses:

Front high-strength fork + adjustable rear swingarm

This creates a balanced front-and-rear suspension arrangement while keeping the scooter relatively compact.

K30

The K30 uses:

Front swingarm + rear swingarm + adjustable springs

Ausom specifically describes the K30 as having front and rear swingarms with adjustable springs, with the larger chassis intended to provide a more stable riding experience.

This gives the K30 a more substantial suspension architecture.

For riders comparing the two, the difference can be understood simply:

K20 = more compact structure with front fork + rear swingarm suspension.

K30 = larger chassis with front and rear swingarms and adjustable springs.

Therefore, the choice between them is not simply about motor power. The two models provide different chassis and suspension configurations even though their core motor and battery specifications are similar.

4. What Does “DGT-Certified” Mean in Spain?

The term DGT-Certified refers to compliance with Spain's VMP technical certification framework.

Spain defines a Vehículo de Movilidad Personal (VMP) as a one-person vehicle with one or more wheels, powered exclusively by electric motors, with a design maximum speed between 6 and 25 km/h. A non-self-balancing VMP cannot simply be equipped with a conventional seat or saddle.

The DGT's VMP technical manual establishes requirements covering areas such as:

• Braking systems
• Reflectors
• Acoustic warning devices
• Wheels and tires
• Identification systems
• Electrical and electromagnetic compatibility
• Structural integrity
• Battery protection
• Anti-slip surfaces
• Speed-control systems

Manufacturers or authorized representatives must obtain a circulation certificate for the specific brand, model, and version.

Importantly, the DGT maintains a public list of certified VMP models. The current DGT list includes:

• AUSOM K20 — Certificate B1155
• AUSOM K30 — Certificate B1156

This provides an important distinction between simply selling an electric scooter in Spain and selling a model that is officially included in the DGT's certified VMP database.

5. Why DGT Certification Matters After January 2024

Since 22 January 2024, newly commercialized VMPs in Spain must meet the applicable certification requirements. The DGT states that only certified VMPs could be newly commercialized from that date.

There is also a transition period for older, non-certified VMPs.

According to the DGT, VMPs commercialized before 22 January 2024 may continue circulating during the transition period until 22 January 2027. From that date, only VMPs with the required certification will be permitted to continue circulating under the relevant framework.

For consumers purchasing a new scooter today, therefore, checking the DGT certification list is an important step.

6. Spain's 2026 VMP Registration Requirements

Spain's regulatory framework has also evolved significantly in 2026.

Real Decreto 52/2026, published on 30 January 2026, established the regulatory framework for the Registry of Light Personal Vehicles and introduced additional provisions concerning VMP registration and technical requirements.

The DGT has subsequently launched the VMP registration process.

For a certified VMP, the registration process requires information such as the vehicle's certificate number and serial number. After registration, the DGT issues a digital registration certificate, which can be used to obtain the identification label.

This means that DGT certification and vehicle registration are separate concepts:

Certification confirms that the particular model/version meets the applicable technical requirements.

Registration identifies the individual vehicle and its owner within the DGT system.

For Spanish riders, both aspects should be considered when preparing a scooter for legal road use.

7. Insurance: An Important 2026 Update

Insurance requirements have also changed.

Spain's Law 5/2025 introduced compulsory liability-insurance provisions for relevant personal light vehicles and expanded the legal framework governing insurance for certain vehicles.

The legislation distinguishes vehicles according to factors including maximum manufactured speed and weight. In particular, the insurance framework defines certain vehicles above 25 kg differently from lighter vehicles.

The DGT states that the registration certificate can be used when arranging the compulsory VMP insurance.

Because insurance classification can depend on the vehicle's legally defined category, owners should check the specific insurance requirement applicable to their individual scooter and registration status before riding on public roads.

8. Basic Road Rules for Electric Scooters in Spain

DGT certification does not mean that a rider can use an electric scooter anywhere.

Spain's nationwide framework establishes several important restrictions.

Maximum speed: 25 km/h

A VMP's design maximum speed must be within the applicable 6–25 km/h range, and the vehicle must have a speed-control system preventing propulsion beyond the permitted maximum.

The Spanish K20 and K30 configurations list a 20 km/h default top speed, providing a margin below the 25 km/h VMP limit.

No riding on sidewalks

VMPs are prohibited from riding on sidewalks and pedestrian areas under the national traffic framework. Municipal regulations can additionally specify which roads, lanes, or areas are authorized for VMP circulation.

No interurban roads

VMPs are prohibited from traveling on:

• Interurban roads
• Highways and motorways
• Crossings classified as travesías
• Urban tunnels

The DGT explicitly lists these restrictions.

One rider only

A VMP is legally defined as a one-person vehicle. Carrying a passenger is therefore not permitted.

No mobile phones or headphones

DGT guidance states that riders cannot use mobile phones or wear headphones while operating a VMP. Riders are also subject to the applicable rules concerning alcohol and drugs.

Helmet requirements

Spanish traffic law establishes the obligation for VMP drivers to use protective helmets under the conditions established by regulation.

Local regulations can impose additional requirements, so riders should check the rules of the municipality where they intend to ride.

9. Which Ausom VMP Should You Choose?

The K20 and K30 share a similar powertrain, battery capacity, claimed range, tire size, and default speed. The key differences are therefore found in their physical format, weight, load capacity, and suspension architecture.

Choose the K20 if you prioritize:

• A more compact chassis
• Lower weight
• Easier storage and transportation
• A shorter folded footprint
• Front fork + rear swingarm suspension
• A maximum load of 130 kg

At 25.5 kg, the K20 is 2 kg lighter than the K30.

Consider the K30 if you prefer:

• A larger overall chassis
• Higher maximum load
• Front and rear swingarm suspension
• Adjustable spring suspension
• A more substantial platform for everyday riding

The K30 weighs 27.5 kg and supports a listed maximum load of 147.5 kg.

Neither model needs to be viewed simply as a more powerful version of the other. Their core motor and battery specifications are similar; the more meaningful distinction is compactness versus a larger chassis and more comprehensive swingarm suspension configuration.

 

10. Final Thoughts: A DGT-Certified Route to Spanish Urban Mobility

For anyone shopping for an electric scooter specifically for Spain, regulatory compliance should be considered alongside range, motor output, suspension, and portability.

The Ausom K20 VMP and Ausom K30 VMP are both currently listed in the DGT's certified VMP database, with certificates B1155 and B1156, respectively.

The K20 offers a more compact 25.5 kg package with front-fork and rear-swingarm suspension, while the 27.5 kg K30 uses a larger chassis and front-and-rear swingarm suspension with adjustable springs.

For Spanish riders, however, buying a certified model is only one part of compliance. Certification, registration, insurance, equipment, speed limits, and local traffic rules all matter. Municipal authorities can also establish additional rules governing where VMPs may circulate.

In short, the K20 and K30 demonstrate how modern electric scooters can combine everyday practicality with the technical requirements of Spain's increasingly formalized VMP framework. Before riding, owners should verify their individual vehicle's registration, insurance, identification requirements, and the latest municipal rules for their destination.
