A would-be bike thief in London was left empty handed as he struggled to negotiate a shop's door.The man entered Cloud9 Cycles in Bloomsbury last Wednesday and spotted a £6,500 ($8,500 USD) Yeti on a bike stand. Footage shows him lifting the bike off the stand before trying to scramble out of the shop with it. However, he bungled his getaway as he was unable to get the handlebars and front wheel through the doorway. Billy Dye, the workshop manager, was watching him on camera and is seen sprinting to confront the man. The thief then panics and flees empty-handed.Billy, who has worked at the store for four years, told the London Evening Standard , “It happened within seconds. I was in the workshop at the back and saw him on CCTV lifting the bike off the stand. I knew he was going to nick it. We are a small shop and the bike retails at £6,500 and for it to disappear would have been a big loss for a small business. It was a spur-of-the-moment decision to confront him and I’m glad we saved the bike.”Shop owner Adam Garrett, 34, uploaded the video to social media and praised “super” Mr Dye and likened him to Usain Bolt. He said, “the man looked so shocked by the speed of our own Billy Bolt. He was frozen in place and threw the bike back, it was over in 30 seconds."
