The battery cover on my eMTB (2022 Cube Stereo Hybrid TM) is poorly secured at one end and I was worried it would disconnect mid-descent and the cover would vanish leaving the very expensive battery vulnerable. No more concerns with this strap, just wrap it around the down tube above or below the bottle cage and cinch it up. Now the battery cover is going nowhere but home again with me and the battery is safe and covered. Very good value peace of mind.
