I have a bit of an odd question that I am hoping someone can help out with. I am a civil engineer designer, who has been asked to specify a bike rack at an elementary school in Concord, MA. I am wondering if MassBike provides any guidance on preferred bike rack types/manufacturers. I know that City of Boston prefers the ‘hitch’ type, and accepts the ‘U’ and ‘ARc’ types, but wondering if there is any prevailing ‘best practices’ when selecting bike rack type. Installing with enough clearance is definitely something we are making sure of in the design.
