Shah Rukh, 49, who is shooting the upcoming film with Shetty in Bulgaria, said cycling will help him to recover from the knee surgery that he underwent last month.
"Good day at work. Hotel Lobby heard Piano man and at shoot Rohit presented me a cycle to get my knee in shape. Yay!," Shah Rukh posted on Twitter.
The "Happy New Year" star underwent a arthroscopic surgery of the left knee at a Mumbai hospital on May 21.
This is the second time Shah Rukh and Shetty has teamed up after the success of 2013 action-comedy "Chennai Express".
