Of course, you can! We have to tell you that extra batteries are always in high demand and sometimes out of stock. So, grab the chance as long as it is available and shows online. And orders for batteries will be fulfilled within our general shipping time the same as e-bikes. If the battery for your e-bike model shows out of stock, please do not purchase any other Heybike e-bike battery because it will not be compatible with your e-bike model. If it’s in urgent need, we recommend you contact our customer service team to help you register and arrange shipment when the battery is available.
