Our Story

Biking has been our life since 2002. It all started after a relaxing ride along Hermosa Beach, where we realized that a good bike shouldn’t be complicated or overpriced. That’s why we started Firmstrong. We wanted to build bikes that were easy to ride, looked great, and helped people enjoy the outdoors with their friends and family.

For over 20 years, we’ve been a family-owned business based right here in South El Monte, California. Firmstrong remains our core brand and our passion, and we take pride in being a local staple in the American cycling community.

Quality & Manufacturing To ensure our riders get the best technology available, we have spent two decades building deep relationships with the world’s leading bicycle manufacturers. Many of the collections we offer are produced in partnership with XDS, a global leader in carbon fiber and lightweight frame engineering.

As a primary retail platform for our California-based company, XDSBikeco.com serves as a direct-to-consumer destination for our high-performance selections. This connection to world-class manufacturing runs through our entire lineup, allowing us to combine global production expertise with our local California service. Whether it’s a branded model or our own custom designs, you are getting a bike built in the same world-class facilities.

Real People, Real Support In an era of faceless online retailers, we stay true to our roots as a local shop. We aren’t a giant corporation; we are a dedicated team in SoCal that’s been around for over twenty years.

• California Based: We ship everything and provide all customer support from our South El Monte headquarters.

• Established in 2002: We have two decades of experience standing behind every bike we sell.

• Personal Service: When you call or email us, you’re talking to a real person in our local office.

Whether you are cruising the beach on a Firmstrong or hitting the road on a high-performance machine, we are here to make sure you have a great ride.
