Santa Fe’s many old, narrow streets, particularly as traffic gets squeezed in downtown, are a major problem. Bikers also note that those sidewalk bump-outs at intersections, intended as traffic-calming measures or to make pedestrian crossings easier, are obstacles for cyclists, pretty much forcing them into the traffic lanes.
I haven't live in Santa Fe in many years, but as I recall it doesn't seem it would be a problem in the downtown area as traffic moves so slowly no one is going faster than a bicycle anyway.
