The Rocky Mountain Overtime Battery Pack makes it possible for you to ride your electric mountain bike that much further than before. You know what that means, you get more time on the trail.

The battery pack is an optional add-on to the Powerplay e-MTB range. Providing riders with an extra 330Wh battery power. This results in a total power output of over 1000Wh when combined with the e-bike’s 672Wh battery.

The Overtime Battery is here to give you more riding time, longer adventures and to never feel like you are missing out.

Save your Powerplay eBike battery. When attached to the bicycle, the bike will normally drain the Overtime pack before touching your Powerplay battery.

Up steep mountain climbs and through tougher conditions, where your e-ride might need a little extra strength, the Overtime may reach its maximum power output and will have to draw strength from the main battery to tackle the challenge. However, when the riding conditions ease up again, the bicycle will switch to only drawing power from the pack again.

Your Rokcy Mountain iWoc remote will display fully charge until the Overtime pack is drained and you start using the main battery. You will know the Overtime battery is running out when the “RIDE MORE, FASTER, FURTHER” LED indicator starts turning off. You will then start tapping into the main battery which will show on the iWoc - display your remaining battery levels.

Top up your electric bike’s battery. If your Powerplay’s battery is drained, the Overtime batch will be able to re-charge it to almost 50% in just over 2 hours. Simply plug the battery into your e-ride and let it supply energy to your MTB.

Do not use any other battery charger other than the standard Powerplay 5A charger to re-charge your Overtime pack as they will harm the power bank.

You are able to charge the Overtime battery in just over 2 hours.
