Jeremy Vine was rushed to hospital after falling unconscious when he fell off his bike.
The Channel 5 star - who is famous for riding a Penny-farthing bicycle round London - told viewers of his morning show about the terrifying incident which happened at the weekend.
The journalist and broadcaster, 56, fell off the vintage cycle and lost consciousness.
He is now recovering from a black eye and revealed to fans he's thinking twice about getting back on his bike, reports the Mirror.
Jeremy opened up on the incident on the Jeremy Vine Show on Wednesday morning and said his glasses were smashed in the incident.
He said:"I didn't see the divot, my front wheel went into it and I went over the handlebars and landed on my head."
A snap of Jeremy's purple eye was also unveiled during the episode of the debate show.
Jeremy previously admitted that riding a Penny-farthing isn't the easiest mode of transport.
"The one thing is, there aren’t really any brakes so you need to step off it to stop. You need to go very slowly and predict lights and stuff, you’ve got to work out when lights are changing and be prepared to dismount. I go about five miles an hour, I go very slowly, and it’s amazing," he told Chiswick Calendar.
A picture of Jeremy's purple eye was also shown on screen.
He added: "Mounting and dismounting is the key thing. Once you’re on it, it’s like riding a normal bike as long as you don’t look down. Mounting and dismount involves basically pushing it, letting it have its own momentum and then climbing up the back. There’s two very small steps on the back of it and so you climb onto the saddle as it’s rolling forward. You can’t mount it pushing uphill for example as it needs that bit of momentum."
Last year, Jeremy caused uproar on social media when he posted a video of a group of cyclists riding four abreast.
The presenter had been a passenger in a car when he filmed the cyclists taking up some of the road.
Jeremy, who is a keen cyclist himself, can be heard in the clip saying: "Sunday morning in the country. Absolutely no problem with this at all. This is exactly how cyclists should ride. They’re calming the traffic behind them."
Alongside the video on Twitter, he wrote: "People who cycle in the country should be encouraged to ride 2, 3 and 4 abreast like this.
The outbursts led to a response by Surrey Police.
The force tweeted: "No driver should need to get angry in those circumstances. Anyone can pass very easily and safely.
"Drivers and riders have to take each section of road as they find it and adjust accordingly; being safe and courteous."
