2.1. In the field of sports equipment, many devices are equipped with electric motors to, for example, maintain higher speeds for longer periods. Drive systems have already been developed for inline skates that are based on a new inline skate design, meaning that conventional inline skates cannot be used with them, or that the technical design prevents free movement when the motor is not in use and creates a braking effect. 2.2 To continue using standard inline skates and to avoid creating a braking effect when skating without the motor, the drive unit was mounted in a frame (1) that can be attached to the skates. To ensure free skating without braking effect from the electric motor (3) when the drive unit is not in use, the drive unit has its own drive wheel (2) which only makes contact with the ground when the motor is in use. 2.3 The inline skate drive is suitable for use with standard inline skates with four wheels, as shown in the drawing. While the inline skate can be ridden as intended without using the drive, it can be engaged as needed and used for acceleration or to maintain speed.
