Bradshaw, 35, well-known as the owner of Bottom Bracket Social Club, worked in local restaurants and bars in addition being a fixture in San Antonio's cycling community. He had planned to open a new bicycle and coffee business later this year.
Bradshaw was riding around 12:30 a.m. in the 1900 block of East Houston Street when a Toyota Corolla struck him from behind, according to a report by Telemundo.
The driver, 67-year old Linda Collier Mason, told police she saw the cyclist but was still unable to avoid the collision, according to a report by Kens5.com. The news site stated that Mason was arrested and booked for Intoxication Assault and Driving While Intoxicated.
Bradshaw was taken to San Antonio Military Medical Center in critical condition, before he was pronounced brain dead at 3:57 p.m., according to a social media post by his friend and business partner Clayton Baines.
Baines has since started a GoFundMe campaign to help Bradshaw's family cover his medical bills and funeral expenses.
