HOWDY!

[S.I.N. CYCLES]

We are S.I.N. Cycles out of Portland, OR. Just the two of us Ryan O'Brien and Harlan Whitman other wise known as "the disreputable SIN Brothers".

Met during a Gravity Bike race and it well went downhill from there. Mostly building gravity fueled machines and what nots. Our first build as S.I.N. CYCLES is the S1 which we made an "instructable" for hoping to pass the good word along that building bikes is bananas. The build can be seen here http://www.instructables.com/id/Gravity-Bike/. We have no secrets from what we learn. In fact we try to expose everything we do learn hoping to get the same in return.


This looks like a super rad crew we are excited to be a part.

Hello and welcome to RatRodBikes!
Gravity bikes . . . I've heard of them mentioned before, but I did not really know anything about them before checking yer "Instructables". Very interesting! You guys do nice work. 8)
I was thinking that it would be a fun ride . . . then I see the pic where you are using the barbed-wire fence as a kickstand while you are rolling around in a ditch! :lol:
