Overview

E-bike X1S Battery & Dual Battery Upgrade Kit

The X1S ships with one battery slot filled and one waiting. This kit is how you fill it. Buy the standard battery as a swap-and-go spare, or buy the upgrade kit to run both batteries at once and double your range on a single ride.

One thing to get right before ordering: the upgrade kit comes in 4-pin and 5-pin versions, and they are not interchangeable. Check the connector on your bike first. The standard battery option is the battery only, and no version includes a charger.

Why this one

Our take

Range is the number one complaint on any sub-$1,000 ebike, and this is the factory answer for the X1S. It's the accessory we'd point every X1S buyer at first.
