Those bikes would become inoperable within days, and could present significant legal liability.

Citibikes and such are quite heavy because they must withstand a lot of abuse. The quality of 'department store' bikes are very low; they're often not even assembled correctly.

Anecdote: I've logged hundreds of hours on mine.

An LLC, waiver and self inspection might avoid the liability. This is just too complicated though.

Obviously, there needs to be a maintenance team.
