Michelin E-Wild GumX tire This E-Wild GumX tire from Michelin is made for electric mountain bikes or cyclists who hate punctures. Thanks to the Gravity Shield in this tire, you really have to try hard to get a puncture! The tire is on the heavy side and is therefore mainly used on electric mountain bikes. The profile on the tire is made in such a way that it provides sufficient grip in the bends, but above all has a very low rolling resistance on the tread. This also ensures that the battery of an electric mountain bike consumes less energy and therefore lasts longer.
