Stumbled on this comparison of 6 DC share pilots while looking for comparative weight of the Citibikes vs other share bikes.

Seems they're all pretty heavy, though it's at the upper end of what seems to be a 35-50 lb range (vs. 70 lbs for a pedal assist)

The really interesting data might be the service life... but that would be hard to get, especially as few locations are going to offer more than one brand long enough to really test that, and wear/abuse conditions probably are different in different cities.
