Watch: Incredible moment a brazen thief tries to steal a bike off the back of a moving car

This is the moment a brazen thief tries to steal a £2,500 bike off the bike rack of a moving car in the middle of London, thankfully not succeeding.

The footage, which was filmed on Sunday afternoon, shows a man on a mountain bike riding up behind the car and loosening the straps keeping the rear wheel in place.

He then keeps an eye on the car as it moves off, and at the next set of traffic lights tries to loosen the strap at the rear wheel and the clamp on the top tube, thankfully not managing to succeed before the car drives off.

The incident occurred on Tower Bridge Road in central London as the bike's owner, Musa Adams, travelled home after completing the London Revolution sportive.

Musa's girlfriend Chloe was driving the car at the time, and spoke to Mail Online about the incident.

"I noticed a guy cycling along behind me, I thought he was a bit close to the back of the car. But I just thought he was being silly - because if I had to brake, then he was going to hit me."

"The next thing I knew, we were at the last set of lights before you accelerate onto the dual carriageway, and I heard a beep from the car behind us.

"As I looked into my rear view mirror, that's when I saw the cyclist twiddling the top fastening of the bike. Just then, the light went green so I started to accelerate."
