Geekhouse is a custom steel TIG welding operation based in Boston, MA. We take ‘Made in the USA’ very seriously.

Founded in 2002 by bespectacled bike-geek Marty Walsh; we produce a range of bicycle frames for all types of riding. We work hard to source as much as possible from within the United States and we hold green business practices in high esteem. By utilizing a small staff, we take the time to personally cater to your ideas and we love watching each and every build take on the personality and individuality of our customers.

Marty started his career in the bicycle industry more than a decade ago working at retail shops, component manufacturers, and for other frame builders soaking up everything he could along the way. After spending some time designing his own out sourced frames he decided to pursue his own handmade operation by apprenticing under Mike Flanigan of ANT (Alternative Needs Transportation) Bikes. Shortly after a two-year apprenticeship Marty secured funding from the City of Boston and Geekhouse was born. Marty hired Bradford Smith in 2010. Brad facilitates fabrication and is in charge of Sugarcoat, our powder coat extension.

Beautiful bicycles are a lot of fun to admire but they’re more fun to ride. We work with American steel because it’s built to last. We TIG-weld because it gives us the freedom to customize every joint to your exact specification. We work with powder coats because they are durable and non-toxic. We do everything we do with a level of intentionality that simply isn’t found in off-the-shelf bikes.


We would love to have the pleasure of building you a custom bike. With a host of options we want to get creative with you so that what comes out in the end is nothing short of your dream ride.
