Amazingly, they are much lighter than some other services.

Boston's Hubway bikes are 3-speed, but 42 pounds despite (I believe) an aluminum frame. New York's Citi Bikes are also 3-speed, but 45 pounds.

Holy crap, I didn't even know you could make a bike that heavy.

Almost all electric bikes weigh more than that (source: me one handing city rideshare bikes after carrying around my electric bike).

Cast iron frame!
