Citi Bikers take note: the system is shutting down this weekend.
A spokesman says they're taking a break to make sure they're up to speed before ridership picks up in warmer weather.
All stations will continue to accept bike returns, but no new rentals will be allowed until the system is back online.
The company is urging riders to return bikes as soon as possible.
To make sure year-long members get their money's worth, CitiBike is extending membership by three days past riders' current expiration dates.
The system should be back to normal by Monday.
