What are my delivery options when buying a bike and accessories?
We offer three options for delivery. Standard home delivery, pickup at a local participating bike shop, and Beeline Bikes mobile bicycle delivery service. Not all options are available for all zip codes and purchase types. Accessory-only purchases are only available for standard home delivery.
What is Standard Home Delivery?
Bikes ship from our warehouse within one business day on purchases before 3 pm EST. Arrival is usually 2-6 business days from purchase, based upon delivery method selected. Assemble yourself! Signature for delivery is required.
How does Pickup at Your Local Bike Shop work?
If a participating bike shop is available for your zip code and purchase type, bike shops will appear as a selection at checkout. The bike is shipped ground to the bike shop. Allow 4-7 business days after arrival for bike assembly. Some fees may apply for accessory installation.
What is Beeline Bikes?
If Beeline is available for your zip code and purchase type, it will appear as an option at check-out. If you select Beeline, we will email you a link that allows you to schedule the delivery date for your bicycle. The earliest appointment date has a buffer built in that allows for the bike to be shipped and assembled by the technician. If you have any questions related to Beeline or scheduling, please call Beeline Support at (855) 582-4537. Some fees may apply for accessory installation.
Do you ship internationally?
Purchases through diamondback.com are not available for international shipping.

My bike did not come with a kickstand, why not?
The majority of bikes do not come with kickstands as some frame materials or styles may not be able to accept a kickstand. Please connect with us via Live Chat or leave a message via the Contact Us page and we will suggest a kickstand for your specific model. Your local bike shop may also be able to help out. If your bike comes with a kickstand, it will be listed under the Specs tab for your bike model as an accessory.
Where can I buy replacement parts for my bike?
We only sell complete bikes and accessories, yet many replacement parts are not OEM-specific to Diamondback and can be directly purchased at a local bike shop; if you have questions about compatibility, connect with our customer service agents here or via Live Chat.
Where is the serial number on my bike?
The serial number is located on the underside of the frame where the pedals and crank arms attach. You most likely will need to flip your bike over. Look for a string of letters and numbers. The serial number is usually formatted like U161K0123456 or DAY16A123456.
