How to build a custom bike with Summit Bicycle's

You dream it. We build it. 

Most bike shops make customers feel like a burden when it comes to custom orders, and that's not right! When you work with Summit Bicycles, you'll always feel appreciated and well cared for.

We know how special a custom bike is, and we aim to make the entire process seamless and enjoyable! 

There are two ways to get started.

Method 1. Build a custom bike directly through the Summit Bicycles Dream Build program

By far the most popular way to build a custom bike with the Summit Bicycles is our Dream Build program, where you explore our whole catalog and start from scratch with the help of our expert team. 

Choose any bike frame we carry or can order, and build it with our extensive inventory of parts. After the frame and parts have all been ordered and received, one of our expert technicians will build up your dream bike.

Once the bike is built, we can ship it anywhere in the contiguous US. And if you're in the Bay Area, you can come visit us and ride it right out of the store.

To get started, contact our team.

Method 2. Build a custom Trek bike through the Trek Project One program

This method is for riders who want a custom Trek bike. You can pick a color scheme that isn't offered at the stock level, and there are a few component options and ways to personalize your bike with custom decals. If that sounds like you, then click the link below to get started.

Excellent service for every type of customer

Whether you have it all figured out or you want some help deciding on the best bike and parts for your style of riding, we're happy to give you as much or as little assistance as needed. 

Generally, customers who are interested in custom bikes fall into one of 3 categories:

The Bike Nerd

Bike Nerds typically know exactly what they want for their custom bike, from the frame to the stem length and everything in between. 

If you have it all figured out and just need help ordering parts and putting it together, we're excited to see what awesome ride you've cooked up in your head!

If this sounds like you, your next step is to browse our catalog, make your mental wishlist, and contact our team

Custom Bike FAQs

Why would someone want to build a custom bike?

Building a custom bike serves two purposes. First it allows you to tailor your bike so that it's perfect for your riding style and goals. Second, custom bikes are awesome! There's nothing quite like riding a bike made just for you, and turning heads is pretty fun too.

Can I customize a bike?

In short, absolutely! The word "customize" can mean replacing a few parts here and there on a stock bike you already own, but it can also apply to starting from scratch and creating something totally unique. One of the great things about bikes is the ability to mix and match parts to build a ride that's perfect for you.

How much does a custom bike cost?

Custom bikes can mean one of two things. 

One option is to work with a custom frame builder to build a frame that's unique to your sizes and preferences, and those frames can cost upwards of $5,000 or more depending on the manufacturer and material. 

The other option is to pick out a stock frame and customize it with parts you select. Quality carbon frames typically cost between $2,000 and $3,000, plus whatever parts you decide on. Both options can add up, it really depends on what frame and components you choose.

Is building a bike hard?

If you don't have any training or knowledge or tools, building a bike is probably not the smartest idea. A stock bike might only need the pedals and handlebars to be attached, but if you're hoping to start from scratch, it's best to leave the installation of all your precious parts to trained professionals. We see far too many customers bring bikes in after having tried and failed to assemble them on their own.

Is it cheaper to buy a bike or build it?

It's almost always cheaper to buy a completely stock bike than to buy all the parts individually and install them.

What size frame do I need for a bike?

Each manufacturer sizes their bike frames a little differently, so you'll need to check out the size charts for that specific brand to find the appropriate size for you.

How do I know what parts will work with my custom bike?

There's no easy answer here. Basically, if this is a question you're asking, you likely will want to get help from a bike shop. 

There are a fair amount of different standards when it comes to bike parts, and components are designed with specific sizes, diameters, and attachment systems. Unless you are very confident in your ability to research the nuances of component compatibility on your own, you should consult professionals at a bike shop.
