Cowboy is a Belgian startup that is developing innovative electric bikes for urban riders. Cowboy’s main goal is to improve urban mobility and take commuters to their destination in a more enjoyable, sustainable and efficient manner.

Founded in 2017 by entrepreneurs Adrien Roose, Karim Slaoui and Tanguy Goretti, Cowboy is headquartered in Brussels, Belgium. Cowboy is the winner of the Eurobike 2017, the Red-Dot bicycle design award 2018 and the Red-Dot “Best of the Best” award for the Cowboy 2.

With traffic congestion plaguing metropolitan areas, electric bikes are proving to be the fastest means of transportation, beating cars and ground public transport. Cowboy’s vision is to elevate the daily commute to the next level in terms of speed, comfort and freedom of movement around the city. Cowboy enhances the riding experience by unifying intelligent technology, delightful design and meticulous customer service.

In April 2019, Cowboy launched its second model, the Cowboy 2, and introduced it to 8 additional countries (Germany, France, the Netherlands, Luxembourg, Austria, Italy, Spain and the United Kingdom). In June 2020, Cowboy unveiled its third generation electric bike.

In July 2020, Cowboy raised €23 Million from international investors (including Exor Seeds, the early stage investment arm of Exor, Isomer Capital, Future Positive Capital and Index Ventures) in the Series B round. Cowboy plans to recruit 30+ new talent in the next six months, scale operations, and expand its footprint across Europe through its Test Ride and Mobile Service networks.
