Siren 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. We’re not a one-person operation & we’re all the better for it!
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 is one of our greatest assets. Located in Tucson (home of Siren East, or SonoraSiren) 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 Tucson riders love riding with him.
Bonnie, Todd, & Finn- race support crew, Siren believers

Bonnie is Queen of the Race Pit. Her skills, dialed to near-perfection, are a secret to Team Siren’s success at endurance events.
Todd- Siren believer, test man, racer
What more can we say for Todd? He loves beer & long days in the saddle. On top of being fast, he’s always pleasant to be around- even at hour 23 of a 24 hr race! The mileage he puts on new product cannot be duplicated with machinery.
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.
Debbie- powdercoater, bicycle lover, red-head
Last but not least- Dave, four-legged badass, 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.



looks like you guys have been having fun on your bikes. I hope the shop works out well for you.
