The 34-year-old headed into the capital this summer as one to watch with real hopes of building on the two gold medals he won in Beijing four years earlier.
But instead Cundy made the headlines for all the wrong reasons as he was disqualified from the C4-5 1km with his back wheel slipping at the start and quickly began ranting at officials.
It was undoubtedly hard for the reigning world champion to take and he had to be restrained by a ParalympicsGB team member before being escorted out of the velodrome.
Cundy has recently watched the footage again and confesses that it does not cover him in a good light.
"What happened in my head and what happened on camera all seemed very similar," he said.
"But it was quite sad to watch and know how it all happened.
"It's kind of frustrating with how the officials worked with it and how it was judged. But that's the way it goes, those are the rules and I had to abide by them.
"I remember every moment. The disbelief of not being allowed to ride.
"I went up and made an apology between two medal ceremonies. After all the media I went back to the village to reset for the next day."
Just 24 hours after his disqualification Cundy returned to the track to claim bronze in the 4km pursuit.
But after failing to claim gold in front of a raucous home crowd Cundy is already turning his attentions to Rio in 2016.
"London wasn't my most favourable Paralympics in terms of performances," said the C4 1km world record holder. "But the actual event was truly memorable.
"The crowds were fantastic. You can't explain to somebody what it was like.
"I would have liked to have won a gold medal and heard what the crowd sounds like. I'll go to Rio and hopefully they'll make noise for us there."
