Electric scooter STREETBOOSTER Castor

Untameable power, premium comfort, and unique design for off-road riding.

Benefits icon Who is this electric scooter best suited for?

STREETBOOSTER Castor is the "untameable brother" of the Pollux model and is the ideal choice for users looking for an adrenaline-filled ride, exceptional power, and premium suspension. Designed for performance with a more powerful motor, this model is perfect for riding on private property, field paths, and rugged terrain. It is suitable for riders up to 144 kg who want a robust scooter that isn't afraid of gravel or hills, and who appreciate unique design and easy maintenance.

Motor icon Exceptional motor power

The Castor boasts top-tier performance. It is powered by a motor with a nominal power of 900 W and an impressive maximum power of 1320 W. With 40 Nm of torque, the scooter easily conquers inclines of up to 20%. This allows for dynamic riding and quick acceleration, regardless of the terrain.

Tyres icon Large 12-inch wheels and comfort

Experience a ride like never before. The STREETBOOSTER Castor is equipped with large 12-inch tires (tubeless, air-filled), which, combined with full suspension, ensure exceptional comfort. On gravel or cobblestones, you will barely feel the bumps, and riding on field paths will be as smooth as on asphalt. Handlebar stabilization further contributes to a safe feeling during the ride.

Battery icon Innovative swappable battery

One of the biggest advantages of the Castor model is the swappable battery system, considered one of the fastest in the world. The 48 V 13 Ah (618 Wh) lithium-ion battery allows for a range of up to 44 km (under optimal conditions). The battery can be easily unlocked and replaced, which prevents theft and allows for charging separate from the scooter. It charges to 80% in just 2.5 hours.

Lighting icon Safety and visibility with turn signals

Safety comes first. The wide handlebars are equipped with rubber-protected turn signals at the ends, which are clearly visible from behind, eliminating the need for repair-prone rear turn signals. The lighting system also includes a brake light, ensuring you are always noticed in traffic.

Brakes icon Reliable braking system

A combination of brakes ensures safe stopping at all speeds. A durable drum brake is installed at the front, and an efficient disc brake at the rear. This configuration provides optimal braking power and control over the scooter in all situations.

Bluetooth icon Smart connectivity and protection

Connect your scooter to the app (Android & iOS) via Bluetooth for access to additional settings and information. The scooter is also equipped with an immobilizer (motor lock) and the option to lock the battery with a key, ensuring a high level of theft protection. The LED display shows all key riding data.

Package icon Robust design and easy maintenance

The Castor was developed with long-term use and easy servicing in mind. With a high IP65 protection rating, it is resistant to water and dust. The scooter's technology allows users to maintain it more easily, meaning less time in the shop and more time on the road. You receive the scooter already assembled and ready to ride.
