DaiQuan Medley, Shop Manager and Head Mechanic

DaiQuan Medley came to Gearin’ Up Bicycles when he needed an outlet for his energies as part of his struggles to overcome behavioral challenges. A the time, DaiQuan was a high School student with a mechanical-focused mind and a leading member of their Robotics team, thus volunteering at Gearin’ Up was just a natural fit. After working at Gearin’ Up through the District’s Summer Youth Employment Program in 2014, DaiQuan officially became part of the Gearin’ Up Bicycles staff in early 2015 as a youth mechanic. Ever since joining our staff, DaiQuan has been a leader in teaching other DC youth about bike mechanics, especially during our Youth Night program. After 4 years at Gearin’ Up, DaiQuan decided to pursue an auto mechanic degree in Pennsylvania, and is now back in the area working at Gearin’ Up before he takes his next step! 

Fun bicycle fact: DaiQuan is an avid mountain biker and frequently rode trails through the PA wilderness during his college days.
