Electric Scooter STREETBOOSTER Sirius

Premium performance, unique swappable battery system, and turn signals for safe riding.


StreetBooster Sirius

Benefits icon Who is this electric scooter best suited for?

The Electric Scooter STREETBOOSTER Sirius is the perfect choice for urban explorers, daily commuters, and those who refuse to compromise on comfort and safety. Thanks to its exceptional reliability and robust construction, it's even used on prestigious cruise ships like AIDA and MeinSchiff for onshore excursions. If you're looking for a scooter with a long lifespan, easy maintenance, and advanced safety features, the Sirius is the right partner for you.

StreetBooster Sirius

Battery icon Innovative Swappable Battery System

Forget range anxiety. The STREETBOOSTER Sirius boasts one of the safest and easiest battery replacement systems on the market. High-quality 21700 cells (Tesla type) are securely stored in a stable aluminum casing. The 36V 9.4Ah battery can be swapped in seconds, effectively doubling your range. With a single charge, you'll travel up to 40 km (optimal) or about 31 km in real-world conditions, and charging to 80% takes only 2.5 hours.

StreetBooster Sirius

Motor icon Powerful Motor for Every Hill

The motor, with a continuous power of 500 W and an impressive maximum power of 960 W, ensures you can tackle even more demanding terrains. With 32 Nm of torque, the scooter easily handles inclines up to 18%, meaning you won't lose momentum even in hilly areas. Acceleration is smooth and continuous, and the ride is quiet and efficient.

StreetBooster Sirius

Lighting icon Handlebar Turn Signals and Excellent Visibility

Road safety is crucial, which is why the Sirius is equipped with powerful turn signals at the ends of the handlebars, ensuring your intentions are clearly visible to other road users. The front light with 50 Lux illuminates the path excellently, while the rear light also includes a brake light, further enhancing your safety day and night.

StreetBooster Sirius

Brakes icon Dual Braking System with Recuperation

An advanced braking system ensures reliable stopping. A durable drum brake is located at the front, while an electric brake with recuperation is at the rear, returning energy to the battery during braking. The system also includes an ABS function, which prevents wheel lock-up and allows for controlled stopping in all conditions.

StreetBooster Sirius

Tires icon Comfort on 10-inch Tires

Riding the STREETBOOSTER Sirius is extremely comfortable thanks to its large 10-inch tires. These are air-filled but tubeless, which reduces the risk of punctures and provides excellent vibration dampening on uneven surfaces. The tires ensure stability and good grip on the road.

StreetBooster Sirius

Display icon Smart App and Protection

Connect your scooter to the STREETBOOSTER app (Android and iOS) via Bluetooth. On your smartphone, you can monitor all important data about your ride, battery status, and settings. Additionally, the app allows for the activation of an electronic motor immobilizer and password protection, safeguarding your scooter against unauthorized use.

StreetBooster Sirius

Warranty icon German Quality and Long-Term Support

The Sirius is designed for a long lifespan. The clean design without visible cables and screws not only means a more attractive appearance but also a lower chance of damage. The manufacturer guarantees 7 years of spare parts supply, which is a rarity in the world of e-mobility. The scooter is also splash-proof according to the IP54 standard, and the folding mechanism allows for easy portability and storage.
