Mack Cycle and Fitness celebrates 60 years as South Miami’s hometown bike shop. Operating the family-owned business is resting more and more on the capable shoulders of the third generation, Rachel and Sandy Losada. Owner Mary Jane Mark looks forward to passing the baton to her daughters.

“The individual strengths of my daughters make the perfect combination for a successful business. Sandy is interested in exploring new product lines and the financial aspects of the business. Rachel has an affinity for people and is very concerned to provide exceptional customer service,”
said Mary Jane.

Mack Cycle is a success story that began when Thaddeus and Helena Mark moved to South Miami from New York in 1957. They bought a business named Mack’s Cycle and Lawnmower repair located in what is now the Community Newspaper building on SW 62 Avenue. By 1969, the business relocated to a building constructed by Mr. Mark on Sunset Drive near City Hall. It has been a thriving shop in that location ever since.

“Dad was a visionary. He rather quickly realized that given south Florida’s climate, bicycles were in use year round and weren’t just hot sellers once a year during Christmas. He began to concentrate on the cycling side of the business when most other national retailers were not,” said Mary Jane.

Mary Jane’s parents established a business model based in valuing customer service, integrity, and participation in community service. Mack Cycle, a shop with the full spectrum of cycling needs, has gained icon status in the Miami area, is recognized as a Five Star Top 100 Bike Store in the nation, and is known to cyclists around the world. The League of American Bicyclists recognized them as a Bicycle Friendly Business at the Platinum level this year.

The first Platinum in the state of Florida, the award recognizes businesses “that are making their communities safer, happier, healthier and more sustainable through bicycling.”

Mary Jane’s business philosophy is patterned on the good habits she learned from her parents. She maintains a strong involvement with the cycling community and cycling advocacy groups at all levels. Her philanthropic nature is shared by her daughters and together they focus on giving back to the community while promoting the sport of cycling. Her parents helped foster cycling by assisting in the establishment of the bike path on Old Cutler Road. Mary Jane funded the creation of mountain bike trails on Virginia Key. Along with Rachel and Sandy, she works for the development of the Ludlam Trail and The Underline, and advocates for Bike 305, a movement to encourage residents to cycle for better health by utilizing trails and public transit throughout the county. Among their many charitable activities are the Dolphin Cancer Challenge, Best Buddies, and the MS 150 Ride.

The future for Mack Cycle lies in the family’s ability to keep doing what they have always done while remaining current with or ahead of the next innovation in cycling and fitness while focusing on value and quality of product lines. They believe that educating children about the importance of cycling as a form of exercise and transportation needs to start as early as possible.

“We work to make Mack Cycle a place to come hang out and learn about cycling,” said Rachel. She reminds us that the sport can take many forms from a short ride to the local store or to the rigors of a triathlon. As an accomplished triathlete who has competed nationally and internationally, Rachel believes in having the shop sponsor triathletes as part of its business model.

2016 Best Buddies Miami Challenge. The morning of Friday, November 18, as an exclusive fund-raiser for the organization, fifty cyclists had the opportunity to ride a singular Miami scenic route with world champion cyclists in a 60-mile peloton.

“Cyclists are looking for sponsors and we feel it complements what we do here to be asked,” said Sandy.

Founder and Chairman of Best Buddies, Anthony Kennedy Shriver said of Mary Jane and her philanthropy, “Mary Jane is the single smartest, most capable and innovative owner of a bike shop in the USA!!!! She is persistent, and passionate not only about the bike business but even more passionate about making her community the best place to live in the world. She is a female business owner who sets the bar so high it inspires others to follow her lead.”

Rachel and Sandy are set to follow their mother’s lead and are prepared to take Mack Cycle and Fitness into the future bringing more business milestone celebrations.
