Well, this is simple. Citi recently emailed me the following:
Cliffs: Use your Citi credit or debit card to save $15 off the $95 annual membership fee.
Granted, saving $15 in New York basically means your next cocktail is free, but it reduces the monthly average cost to only $6.666 repeating (obligatory Kramer paying with pennies video). Considering maintenance and parking is free and it is summer, CitiBike is a galactic-sized bargain. Feeling the wind on a bike is loads better than the stale, summer air during the sticky months, anyway, and there’s nothing like flying down a boulevard in a big city.
So sign up!
