The "knee meets rock" duel is unfair and painful. Knee injuries are complicated, long-lasting and avoidable, as modern knee pads absorb up to 95 per cent of the energy of a fall.

We tested the protectors on a standardised test stand. In accordance with the motorbike test standard EN 1621.1, each protector in our test had to withstand three impacts. A 5-kilo iron block fell from a height of one metre onto the "sensor knee" with protector (photo) and hit three different areas. The sensor recorded the residual energy - the higher the value, the lower the protection. For the safe protection level 2, the residual forces must not exceed an average of 20 kilo newtons (kN); for the more tame protection level 1, the limits are 35 kN for the average of the blows. The standard limits only represent minimum requirements. We checked the fit and wearing comfort by wearing the protectors during our bike tests and also covering a pedalling distance of 25 kilometres with each protector.

We put these 16 knee protectors through their paces for you - you can download the entire test from FREERIDE 3/2020 as a PDF below the article. The test costs 1.99 euros.

Why not free of charge? Because quality journalism has a price. In return, we guarantee independence and objectivity. This applies in particular to the tests in FREERIDE. We don't pay for them, but the opposite is the case: we charge for them, namely tens of thousands of euros every year.
