I have a question about a bike I’m shopping for

What if my retailer does not have the bike I want?

All Trek retailers can place an order for you. The faster you place your order with your shop, the faster the bike will arrive.

What 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.

Do 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?

Unfortunately, we do not offer touch up paint at this point in time. Often close paint matches can be sourced through means like auto-body shops or even finger nail polish for minor touch ups.
