Some battery packs on the Current-Series e-bikes have a tight fit for the first couple of installations. Some force may be needed the first few times you install the battery pack. Below is a link to a video that provides more detailed instructions about installing the battery pack.
All of our bikes have been tested at the factory to ensure that the battery will fit. Customers who have reported tight-fitting battery packs were all able to force the pack in with some effort. If you still have trouble installing your battery, contact our technical support (linked) team.
