Tradekar has been developing, producing, and selling smart, practical, and affordable leisure products to support everyone’s free time for more than 40 years. Major bike carrier brands such as Spinder and Pro-User Bike Carriers operate under the Tradekar umbrella.

Spinder bike carriers have existed since the 1980s. Through continuous development and innovation, we are able to offer a wide range of bike carriers and accessories. The carriers are suitable for 1, 2, 3, or even 4 bikes, and can be mounted either on the tow bar or on the roof of the car.

All extensively tested for maximum safety!

In 2000, Pro-User Bike Carriers began developing bike carriers, and in 2001 the very first model was introduced. This was the start of a successful journey. Continuous development has resulted in a complete line of bike carriers in 2025. From the very beginning, we have worked closely with our trusted partner, with several patents granted on unique features. Our bike carriers are constantly being improved and equipped with smart innovations, and have repeatedly been awarded Best Buy by the Dutch Consumers’ Association and Test-Aankoop in Belgium.
