MAKE Instructable member Honus shows how to build a single speed suspension bike – “I had previously sold my mountain bike and I really missed it so I decided to put together a new bike using parts I had in my garage. I built a similar frame around ten years ago when URT’s (unified rear triangle)were somewhat popular and it actually rode pretty well so I thought I’d use a similar design for a fun single speed. It may look flexy but it’s really pretty stiff in torsion- the boom tube is made from .049 wall 4130 and the pivot is pretty beefy as well. The pivot sits directly over the BB so the suspension is always working, even when you stand, unlike the old URT designs.” – Link.
