He pleaded guilty to the offence at his first court hearing and returned on Thursday to be sentenced.
Gerallt Evans, Deputy Chief Crown Prosecutor for CPS London, said: "This case has quite rightly caused shock and outrage among the general public.
"Kashif Samuels used abusive anti-Muslim and racist language against the victim and caused distress and alarm to the other passengers on the bus. Not only did he shout and swear at the victim but also threw the victim's walking frame from the bus when it came to a halt.
"This appalling outburst was caught on camera by a public-spirited fellow passenger and left Samuels no choice but to plead guilty.
"Hate crime of any kind will not be tolerated in London. Members of the public should be able to travel on the city's transport network without fear of violence, abuse or harassment and we will continue to work with our police partners to bring those that commit these crimes to justice."
