Many existing systems are equipped with primitive brake mechanisms that require the users to bend their leg in order to activate mechanically such a mechanism. This can be quite cumbersome for a user to operate, particularly for a beginner who has relatively little experience in skirolling, during instances of emergency, or during cornering or skiing on inclined surfaces, for example. Moreover, many of these existing brake mechanisms act on the outside of a wheel, so they are prone to variable effectiveness due to the presence of dirt, gravel, water, etc. that can accumulate on the wheels’ surface. For these reasons ski rolls are considered not so safety, especially fornot experienced users. For these reasons, restrictions on the use of ski-rolls on public roads exist. A braking mechanism activated by the hand of the skier would be much easier to be used and more effective, improving both the comfort and the safety. Moreover, a mechanism that acts on the rim can avoid the wear of the rubber wheel.
