Too heavy, too sluggish - for these reasons, puncture protection tyre inserts are a rare species on conventional mountain bikes. On e-MTBs, the systems have what it takes to make a breakthrough, as the additional weight plays a subordinate role thanks to motor support. The little helpers significantly minimise the risk of punctures and make e-biking more carefree. We recommend additional protection, especially on rear wheels with wide plus-size tyres, so that the tyre can be ridden with low air pressure, which improves grip. This requires the tyres to be fitted tubeless. All systems only work with tubeless systems, for which almost all rims and tyres on modern e-mountainbikes are now prepared.
