Judi Tentor on her bike

Judi Tentor

Judi Tentor lives in Mission Hills, grows a lot of food in her garden, and gets around by bicycle as much as possible. She has been navigating the streets of San Diego by bicycle and transit since 2008 when she sold her Honda Element. Her passion for the environment and sustainability drives her everyday actions. Riding a bicycle, she believes, is more than a fun activity, but also a tool for transportation as well as a solution to environmental, social equity and health issues that matter to her.

Judi is also a Cycling Instructor (LCI #5098) certified by the League of American Bicyclists, the oldest bicycle advocacy org in the US. She teaches beginner classes for adults learning how to ride for the first time and traffic skills classes for intermediate riders through nonprofit organizations. She is an advocate for active transportation and a feminist, hoping to inspire more women to ride bicycles for the benefit of their health, spirit, and the planet.

As a bicyclist, advocate and cycling instructor, she has been leading efforts to get more bicycle infrastructure in San Diego. She currently serves on the board of the Mission Hills Town Council. When not pedaling and sometimes while pedaling, Judi takes photographs of people riding bicycles and bicycle infrastructure around the world. She holds a bachelor’s degree in Environmental Science from SUNY ESF and a Masters of Landscape Architecture from The Ohio State University, and was awarded a Comprehensive Bikeway Design Certificate from Portland State University.

Nicole Burgess

Nicole Burgess

Nicole Burgess is a passionate bike advocate that loves to ride. With the Dutch blood, she understands all the joys and benefits of riding a bicycle for transportation and continues to advocate daily for San Diego to become a World Class Bicycle Friendly City.

Nicole grew up in Bonita and enjoyed the many adventures riding the tandem with her brother; especially the frequent rides to National City to visit cousins, which provided the seeds to understand the freedom of riding a bike.

Nicole received a BS in Physical Science at CSU, Chico and loved the small college town where she could venture anywhere on her beach cruiser, even experiencing her first awesome ride in the snow while going to class. She would come back to San Diego and get her Single Subject Science Credential and become a teacher within the SD County Court School System for alternative education for some of the most at-risk students in our region.

Nicole was fortunate enough to take time off to raise her children in Ocean Beach and it was her children that were the impetus to become known as the OB Bike Lady. As her children attended Dana Middle School for 5th and 6th grade, Nicole began and continued the Dana Bike Train for 6 consecutive years. She would encourage, educate, and support local students to become active in their commutes to school. As the bike train grew to 20+ students at times, Nicole became involved at the City, SANDAG and local community groups to advocate for safe bike infrastructure to support Safe Routes to Schools. For over the past 10 years, she has persistently and constantly urged the City and County agencies to collaborate to provide healthy transportation mobility options for all the benefits it has to offer.

Over the past ten years Nicole has pedaled over 60k miles near and far and has traveled by bike along the West Coast, most of the East Coast, across many northwest states, and even ventured through Nova Scotia, Holland, Denmark, and Guadalajara to experience all types of cities and how they accommodate people who ride bikes.

With the amazing beautiful weather, the wonderful innovative electric assist bikes, large available roadways, and a population of people that love to be outdoors and stay fit, Nicole believes that SD is an ideal location for Bike Utopia to protect our environments, improve public health, and to create a vibrant city for people to truly enjoy.

As a League Certified Instructor and a certified Hatha Yoga Teacher, Nicole embraces the beauty of riding daily and hopes to inspire more people to explore their city by bike. If interested in learning to ride, to organize a local bike train, to travel overnight on a bike, or to practice your yoga lifestyle while riding, Nicole is your resource and is always ready to help others enjoy the beauty of riding a bike. For most of her advocacy work, you can follow her on Twitter @Nicoleburgess23 otherwise feel free to send her an email at if you just want to ride.
