We know you’re excited to receive your gear and we’re stoked to get your gear out to you! Orders placed on BlueZoneSports.com will typically ship from our fulfillment stores within 1-2 business days.
In order to provide the best possible assortment on BlueZoneSports.com, we fulfill all orders from our chain of store locations. While this may reduce shipping times, this may result in portions of your order being shipped in multiple packages and/or having multiple delivery estimations.
We understand that many adventurers outside of the U.S. want to experience the BlueZone. Unfortunately, at this time, we are unable to ship packages internationally.
All bicycle orders placed on BlueZoneSports.com will be shipped via Bike Flights. Bike Flights is a 3rd party transit service we use to ensure your bike is delivered safely to you. This service will allow us to add insurance to your package and may require a signature upon delivery subject to your order total. Please allow 3-4 business days for your bike order to be processed. All bikes ship from our retail locations and are first assembled and inspected by our team of expert bike technicians, then repackaged and shipped to you. You will receive a separate email with your tracking information.
Please note that there are some bike brands that we cannot ship, however, we do have a pickup in-store option available.
Final assembly on all bike purchases MUST be done by a qualified bike technician. Failure to have the bike assembled by a qualified technician AND retain a copy of your labor receipt may void the manufacturer warranty and could result in damage and/or injury if not assembled correctly. Please note that as an industry standard, some bikes might have minor cosmetic blemishes due to the nature of shipping. Please report any damaged part that affects the safety or ride-ability of your bike immediately upon receipt.
Shipping information such as address changes are adjustable up until the time of shipping. Once your package has left our fulfillment store, you will need to work with the carrier to adjust the information.
Once you have placed your order, we cannot change the shipping method. Please make sure to carefully review your order before submitting to ensure you have selected the right shipping method.
If you have a gate code or special instructions for delivery, we recommend using the free delivery service options from UPS. These services will alert you of incoming packages, allow you to add delivery instructions, reschedule the delivery and more. These services are free to sign up, however, some features may incur a fee. For more information regarding these services, please see the link below.
UPS Ground shipping and UPS 2nd Day Air shipping time frames are only estimates. Transit times are out of our hands once your gear leaves our fulfillment stores, and we cannot guarantee the time frames of these shipping methods. View estimated UPS Ground transit days based on when your package leaves our fulfillment stores. Please note UPS is not guaranteeing delivery times and these are approximations only.

All orders over $250.00 will require your signature upon arrival. Please make sure to check your tracking status so you know when your order is expected to arrive.
Some people outside of the U.S. may use a package forwarder to get their gear abroad. Please be aware that BlueZone Sports and BlueZone Sports’ partners and vendors cannot be held liable for damage or costs that may occur after the package has been delivered to the shipping address provided at the time of purchase. If you plan on using a package forwarding facility, please contact us prior to placing your order.
We want to make sure you get your gear in time for your next adventure but there are some times of the year where we need to give our hard-working UPS workers an extra day or two. Please give your package a few extra days to arrive if you placed your order around one of these dates.
