This technically isn't a service but still in the zone of bartering and since people do for items like art on here so it seems like it works. Basically I'm looking for a used bike for commuting purposes. It doesn't have to be nice, just has to work. If you have an old one that I can take off your hands, have some simbi. :D
My main service offered on Simbi is Ruby tutoring and I'm happy to do that as well if that'd be more valuable to you.
