Instructors

Victoria Sommers

I sometimes say that cycling saved my life.  

I was born and raised in Buenos Aires, Argentina. When I was 19, after months of knee pain, I went to the doctor, who recommended surgery. He also suggested I try light pedaling on a stationary bike. I took my first indoor cycling class and was hooked. Seven months later, my knee was pain-free. I never needed surgery.

Cycling indoors and out became a daily part of my life, both for my knees and for the amazing  mental benefits. A few years later, I moved to West Palm Beach, Florida, where I joined a small cycling studio, first as a client and then as a teacher. (My day job was corporate sales but my passion was the studio.) I was invited to teach as a guest instructor at Equinox in NYC and had the honor to ride the Yellowstone National Park with Greg LeMond. 

The cycling studio had a great community with warm people who became like a family to me, and who stood by me during the hard times that eventually led me to decide to move to California. 

When I landed in Los Altos, I knew I wanted to create my own cycling community here. My parents were small business owners in Buenos Aires, and I absorbed lessons about entrepreneurship around the dining table. From them, I learned the true meaning of grit and perseverance, powerful tools to have when starting a business. 

I opened Momentum in 2013, and have watched it blossom into a strong community that supports its members and brings happiness as well as health to their lives.

I love being a business owner, but I’m still happiest on the bike, leading a class, making that special hour a time to connect with ourselves and with each other. I love to crank up the high beat music, focusing on positivity and empowerment as we all strive to be the best version of ourselves.
