proteus bicycles. transportation with benefits.

It’s not just about bikes. We are a full-service bike shop (new bike sales, accessories and clothes, repairs).  But we try to be more than that. The most important thing to us is that you get on a bike and ride to your heart’s content. We want to make sure you get on the best bike for you, and be sure it fits you perfectly.

Thursday nights we’re open late. Come over for food, drinks, and conversation!  We have a comfortable space, a cozy fire, and a charming staff. Most of all, we have really cool customers. Come in and meet them: recreational cyclists, roadies, commuters,  mountain bikers, cyclocross racers, fixed-gear fans and everyone in between.

    Hi, a month ago I came in and asked for a few old junk bike cassettes to re-purpose into part of a costume. You had a few and let me have them. I wanted to say thanks and they worked great! I’d love to email you the set of pictures. I posted 2 of them on the Proteus Facebook, but I wanted you guys to have the picture set. Thanks again, and if you ever have more junk cassettes I can probably build you a wall clock for the shop.

    Tax money is coming in so I’m in the bike market. Interested in a 2013 Kona Jake (like the triple) in size 53 or the Bianchi Lupo (also size 53). LOVE the Volpe but its out of my price range. Any chance either of those are in stock for a test ride/purchase this weekend?

    • admin says:

      Hi Eric, it looks like there are both 53 Jakes and Volpes in stock (all 2014s I think). No Lupos in stock, but can probably be ordered quickly. I’d also consider riding the Jamis Quest comp? It’s in stock in 54cm. Call Paul or Ben at the shop to make sure they’re built up and ready to test? -Jeff

    Proteus Stand over height is at least 38″

    Got any Jamis dragon sport 29 ERs in stock? I am 6’2′ and don’t know if I need 19 or 21 size.

    • admin says:

      It looks like there’s Jamis Dragon Sport 650 (27.5″ wheel) in both 21″ size and 19″ in now. -Jeff

      PS Call Paul at the shop for MTB inventory and builds. 301 441 2928

    I bought the Kona Splice 19″ yesterday, and I love it! Regarding the first tune-up, how many miles must I ride or how many months must pass before that first tune-up? Is it whatever occurs first? Thanks. Ted

    • admin says:

      Nice! It’s usually within 3 months or 100 miles or so. After a few weeks, the cables will stretch a little bit and the shifting might lose its feel. That’s a normal part of a bike build, and that’s why it’s important to get your warranty tune. Please call the shop if you have any trouble or questions. Often the mechanics can schedule warranty tunes for a particular day or narrow range of days so you don’t have to be off your bike for long while it’s in the shop. -Jeff

    Thanks Jeff for your response. Ted

    I have a 2013 Kona Jake which I love but would like to upgrade the disc brakes. Is there any that you would suggest/carry that would be compatible with the Shimano Tiagra shifters?

    • admin says:

      I run Avid/SRAM BB7s with Tiagra on my touring bike — I like them because they’re easy to adjust and dial-in, and they have good power.

      I’ve forwarded this to the shop’s mechanics — if you want to just call them and save the time of waiting for a response on the Interwebs, it’s 301 441 2928 — ask for Johnny, the other John, Ben, or Paul.

    Regarding the Beginner ride on Saturday, June 14, is there a location to meet up?

    • admin says:

      Yes, thanks for prompting. Meetup will be either at 8am at Proteus or approximately 8:20-8:30am at Lake Artemesia at the main gate on the north side where you come in from the parking lot. There’s a seating area by the lake just near the gate.

  9. Rob says:

    I need to have my seat tube on my steel (531) bike replaced. Is there someone still associated with Proteus who does frame repair? Thanks.

    • admin says:

      Hi Rod, I’d talk to Ben — he’d know best. Ben is on vacation today (Friday) and Saturday, but will be back Sunday-Tuesday.

  10. Linda Rohrbaugh says:

    Hi, I bought a Windsor Carrera bike from your shop back in 1982 and want to sell it. Could you possibly provide me with an estimated price range? Everything is original and in working/good condition (tape could be redone), it has probably fewer than 250 miles on it. Made in Japan, Cr MO, I can send pictures. Thanks!

    • admin says:

      Hi Linda, I have no idea how to value your bike, but if you bring it in to the shop some day, maybe the mechanics can give you a ballpark estimate for a reasonable Craigslist price. Are you still in the area? Lots of people like those old road bikes, especially if they’re in good shape. -Jeff

    Please help find STOLEN FOLD-UP BROMPTON BICYCLE (that needs a repair)

    My black folding bicycle (Brompton M6R-Plus) is six years old and it happened to need repair to the gear shift.

    As a defense against theft, I had painted a dozen or so silver stars on the top bar of the frame. (Of course they could be painted over.)

    The bike is registered with the National Bicycle Registry.

    It was stolen in early July in the afternoon in front of the very busy McDonald’s at Verizon Center. It was securely locked with a Kryptonite U-bolt lock to the bicycle stand. I was in a store for about ten minutes. The thief must have picked the lock.

    Please notify me if you have any information about this bicycle.

    Thank you.

    hello proteus,

    i got a really beat up raleigh. all parts were very rusty and choke covered in gobs of brushed on black paint. the only thing salvageable was the frame and maybe the caliper brakes.

    i’m wondering if you guys would build me a simple freewheel single speed with front/rear brakes. i’ll need a new headset, maybe a new cassette, crank arms, pedals, chain ring, front/rear wheels, and maybe new caliper brakes. no part needs to be fancy, just generic A to B types will do; used parts from other dead bikes would be brilliant. i will provide a saddle, seat post, handle bar, and brake levers.

    would you guys do a project like this? if so, how much?

    thanks for your time.

    • admin says:

      Hello Hank, the answer is yes, we do this sort of thing all the time. Best to bring it in for an estimate, get an idea what it needs, and make a deposit. Best times are weekdays and Sundays. However, you may find that the sum of the parts and labor to rebuild adds up, and that you could get a new bike for less. The mechanics will discuss with you — they love to fix up old bikes. Current timing on a bike rebuild would probably be at least two weeks — again, you need to check with the mechanics.

  13. John says:

    I am really interested in trying out the Kona Unit. Do you have the bike in stock? if so what model year(s) and size(s)? Thanks in advance!!!

    • admin says:

      Hi John. No Units currently in stock, but we can get 2014s from Kona Laurie says. Paul at the shop owns a 2013 19″, which he may let you test ride, although it currently has road tires on it from bike party. The Unit is an amazing ride, my favorite, actually. -Jeff
