I have a question about a bike I’m shopping for
How do I find my closest retailer?
Your local bike shop is your local resource for all things cycling and Trek, Bontrager, and Electra products are only available at the very best ones. Use our Shop Finder tool to find your closest retailer.
See shop finderWhat size bike do I need?
The size bike you need depends on a few things but primarily the combination of your height and inseam will determine what size bike will fit you best. Our Size Finder can help you find the right bike for you.
See size finderDo you accept trade-ins?
Every shop manages their own trade-in or trade-up policies in a way that makes the most sense for them. If you have a bike to trade-in, the best thing to do is check with your local Trek retailer to see what options exist.
I have a question about a bike I own
Where is my bike’s serial number?
If you tip your bike upside down, there should be a serial number on the bottom of your bike on a silver or grey sticker. Serial numbers typically start with a “W”.
Can my serial number tell you what bike I have?
Only if the bike was registered after purchase.
Do you have touch-up paint?
We offer touch-up paint for many of our bicycle paint colors. Close paint matches can also be sourced through means like auto-body shops or even finger nail polish for minor touch ups.
What type of warranty does my bike have?
We offer the best warranty policy out there.
Warranty detailsDo you have a manual for my bike or accessory?
Oh, we have manuals. So many manuals. Check them out here.
