Who works at bikes@vienna?


Tim Fricker

Owner and General Jack of All Trades

Tim came late to cycling, not learning to ride until he was 12, but once he started, he never stopped. A self-taught mechanic, he became Head Mechanic here in 2005 after twenty-odd (some would say very odd) years working in technical theatre, and a short stint at a non-profit bike shop in Portland, OR. In late 2010, he took over ownership of bikes@vienna when founder John Brunow moved back to Iowa.  Tim’s interests and passions include classic steel road bikes, photography, reading, the outdoors, and old typewriters.  When not at the shop, you’ll often find him walking or riding the C&O Canal, one of his favorite National Parks in the US.


Chester Proudpaw

Chief Morale Officer and Mouser

Chester came to us from the woods of Pennsylvania, when Tim found him hanging out around the cabins in a state park just after Thanksgiving 2022.  He's definitely settled in as our shop cat, and you'll probably see him here on most days we are open, except on the days we have all the doors open.  He can be shy sometimes, but generally loves attention, even from strangers.  And he really enjoys a good nap.  He definitely helps keep morale up at the shop!  His excellence on the job has been recognized with Employee of the Month… three months running.  His natural modesty regarding his talents so far has warded off grumbling from the rest of the staff. You can learn more about him on our blog entry Our New Staff Member.


Daniel Nanovic

Head Mechanic

Daniel began working at Revolution Cycles in Clarendon in the Summer of 2008 after graduating high school. He quickly discovered a knack for all things mechanical especially when it comes to bicycle repair. After spending a year at college in Montana, he returned after discovering that engineering was not the right path, and continued to work as a mechanic and bike assembler at other local shops including Spokes Etc. and Revolution Cycles. In 2010, he discovered Bikes@Vienna and applied for a job. Daniel stepped up as head mechanic when Tim took over the business. Very well versed in all manner of bike technology; he has an innate knack for troubleshooting that means your bike is in good hands when it comes in for service.


Beth Permenter

Service Manager and Social Media

Beth joined our shop on Christmas Eve in 2018 and has very quickly become immersed in our unique shop culture. She has an English degree from G.M.U. Her original plan was to become a librarian until she discovered her passion for bike mechanics. Now she will be a well-read bicycle mechanic. Beth has done work with the bicycle community, such as running the after school bike mechanic program at Herndon Middle School. After she graduates in May 2020, she plans on continuing her work at this program, as well as her work at Bikes@Vienna. Beth is an avid bicycle commuter and rides her 2017 All-City Macho Man equipped with Carradice bags full of books to Vienna, Reston, and downtown Fairfax. She also bikepacks on her Surly Troll and travels around on her 2003 resto-mod Brompton. Beth enjoys riding the local singletrack such as the C.C.T. and Lake Fairfax. If you have any bikepacking questions, she is the lady to talk to! Be warned though! She loves to info-dump!
