With the EVOC FR Enduro E-Ride 16 Protector Backpack, we no longer have to push our rig up hills when it runs out of juice. We throw our extra battery in the pack before a long day out, so we can stay in the saddle rather than slogging uphill by day's end. EVOC has designed the bag with safety features at the forefront to make up for the higher speeds and heavier cargo with a fully loaded battery and hydration bag in tow.
