City buses are not making the grade according to a new study.

Only two lines in the city got an "A" in the report by The Bus Turnaround Coalition - the BX-29 in the Bronx and Q-35 in Queens.  

In Manhattan, a whopping 36 buses received a failing grade. 

Queens had 21, Brooklyn had 14, the Bronx 14, and Staten Island had two buses with an F. 

NY1 caught up with bus riders in the Bronx, who say they agree with the report.

"This sucks. It's like extremely long- it's like they're coming from somewhere no one else is coming from," said one rider.

"It sucks. Because, especially the 23 bus, it takes too long and we're just standing there in this cold," said another rider.

"It's cold, we have to wait out for like an hour, especially the 29 bus on City Island. It takes a long time," added a third rider.

The coalition also made recommendations to improve buses around the city.

They include designing streets to prioritize buses, transforming how customers get on and off the bus, and increasing transparency about bus performance.
