voter outreach and community organizing. She has many memories of
bicycling while growing up in Iowa, and enjoyed bicycling as her main
form of transportation while living abroad in Spain for several years.
Returning to the States and moving to San Diego allowed her to
realize the extent to which cars are prioritized in our transportation
systems. After living here over a year, she still finds herself sometimes
afraid to explore new areas on her bike due to safety concerns. She
sought out SDCBC in the hopes of helping create a San Diego where
people from all walks of life can get around safely and comfortably
using their bicycles, and where bicycling as a means of transport is
viable across the entire city. As a board member, Dorrie will represent
young, female, and casual bicyclists, and those who want all people
and communities to be able to share the joy of bicycling!

Kirie Hodges

I don’t remember my first baby steps. However, I vividly recall the first time I successfully rode my bike without training wheels. Some of my earliest memories are of riding with my dad in a child’s bike seat as we rode around with my mom and sister as a unit. When I was an adolescent, my cousin and I used to spend our summer days riding miles around the neighborhood. We rode until the tires were flat, and then we learned how to patch and change a tube. Although I wasn’t one of those kids, I used to admire the students who rode their bikes to school.

Nowadays, as an adult and a proud parent of a six year-old boy, we ride our bikes (metal horses) daily. My son can echo the ABC’s of biking (Air, Brake and Chain) and he knows how to safely ride his bike. We ride together all the time, and while keeping our heads on a swivel, we see that we have inspired others to ride their bikes too.

David Leyva

David Leyva is a news producer for CBS 8, and a three-year San Diego resident. His passion for cycling was something he inadvertently stumbled upon after getting into a car accident. He resorted to a used bike from craigslist to get to work, and quickly fell in love with the long commute and the freedom of being on a bike. Although he got a new car, cycling became his favorite way to get around, and soon ventured into longer and more adventurous rides. Today, he rides primarily for leisure and is always on the lookout for fun and creative ways to get around San Diego. As a board member, he hopes to help address the needs of cyclists who ride for fun and those who use bicycles as a primary source of transportation, especially in underserved communities.

Dave Nichols

David Nichols is a retired middle school teacher who has been involved with the San Diego area cycling community for the past 38 years. He has been involved in all aspects of cycling including commuting, touring, track, mountain, as well as racing competitively. David commuted to work for most of his career, toured throughout the US, raced on the velodrome, and ridden the backcountry on mountain bike. He has logged as much as 20,000 miles in a single year, and set numerous course records in races, including San Diego to Yuma. David has volunteered to plan and organize many cycling events throughout the county. He is the event director for the Gordy Shields memorial ride as well as the Route/Bike Marshal coordinator for Ride the Point.  


David would like to create an environment that encompasses and supports all areas of cycling, and prepares our community for generations to come as we enter into a new era of safe cycling for all ages, all abilities, all cycling passions.

Moline Shrader-Nelson

Moline was four years old when she learned how to ride a bike. She still remembers the day her Dad taught her to ride, and she’s been at it ever since. She rides for fun, for exercise, and for getting around town. Moline believes that everyone should have the ability to bike, and she wants to further increase the inclusiveness of biking culture. 
Today, the biking world can act as a bridge: enabling those who were once left behind. These days there are bikes for every need; from 2-wheelers and trikes to recumbents, ebikes, handcranks, tandems, and more. But all these new bikers need more and safer bike lanes.
Moline’s work with SDCBC will help eliminate some of the challenges cyclists face while out and about. Ultimately, her goal is to inspire everyone and anyone to bike.
“My car takes me places I can’t go on my bike. But my bike takes me into a world that I can’t go to in my car.”

Linda has been riding San Diego county roads for over 50 years. Her earliest bike memory is watching the 1962 Tour de France with her father, then organizing races with the neighborhood kids.

Serge is skeptical about the effectiveness of most bike infrastructure in terms of significantly increasing ridership and improving actual rider safety. He believes more emphasis on education and marketing good traffic cycling skills and practices would be far more effective at making cycling safer, more enjoyable and more attractive for anyone 8-80. He would like to see more emphasis on getting the 2% of the population that does 90% of the riding to use bikes more for commuting and other utilitarian trips.
