The People

sirena.gifSiren Bicycles is a handbuilt American mountain bike company. We strive to build elegant, beautiful frames & complete bikes. This blog chronicles the inspiration & creative process of our work. Please check out our website for more info & hard numbers on the bikes.

Who are we? here’s the faces & names. Some of us are full-time Sirenites, others are part-timers; but every one of us are in this passionately & contribute equally important creative bits in the overall Siren picture.

Brendan– Founder, Designer, Owner, Fabricator, Janitor


Brendan has a diverse background in aerospace, fine art, and manufacturing. Additionally, he served 16 years “in the trenches” at local bike shops & loves dogs. He does not particularly like pina coladas or getting caught in the rain.

Mary– 2008 Tour Divide racer…. 2,711 miles on a Song 29. Mary is the X chromosome of Siren; a major design contributor & the inspiration for the first Siren- the Fifty-Five.

Phil– engineer, manufacturing guru, master of all things quantitative.

Phil’s manufacturing experience is deep & always seems to have a solution to our manufacturing problems. He knows his stuff in the shop & in the singletrack as well.

Matt– idea bouncer, design contributor, therapist

Matt’s blend of energy & level-headedness has been one of our great assets. He has been known to host 24-36 hour design & fabrication binges- a sure fire cure to the bike world’s equivalent to Writer’s Block. Besides being a great Tinkerer, it is also a well-known fact that 4 out of 5 people love riding with him.

Mike- TIG welder & teacher, lover of “the puddle.” Mike once said “I’m into welding like some people are in to, say; coffee.” Mike’s attention to detail & skill with a torch cannot be overstated. He’s constantly pushing his process limits & learning the metallurgy & science behind the weld. He is the reason our welds are the best in the business.

Last but not least- Dave, four-legged baddass, shop keeper

Dave has 10 years of singletrack experience & loves the zen-like state one can only achieve when seeing the trail from bottom-bracket level.

  3. hi, bobby here from the Philippines, i really like your designs, but couldn’t afford them. but i use a fifty-five here in our country on a regular MTB steel frame.

    i would like to ask what gear combinations do you use on your fifty-five’s on trails. i am a bicycle messenger and i use a 36×17 on road, on my fifty-five.
