E-bike thieves brazenly snatched a phone from the hand of a shocked man on a busy street corner.
The hapless pedestrian chased after them but then was forced to give up as they whizzed off.
The two riders targeted the unsuspecting man standing by the kerb with a woman.
The lead thief then swooped in the blink of an eye.
The man carrying a white bag looked like he was about to cross the road when the black-clad rider ripped the device from his hand.
The stunned man then attempted to give chase before giving up the futile attempt, as reported by Need To Know.
It was filmed in Knightsbridge, west London on Wednesday (14 Feb).
One local said: “They need to up the sentences for this.
“Absolutely disgusting.”

Another added: “Get a wrist strap case and keep your phone in your pocket in London as much as possible.”
One added: “Literally need to kick them off from these electric bikes towards a running vehicle.
“Otherwise they won’t learn a lesson and will keep stealing stuff from the general public.”
And another said: “Keep your phone in your pocket.

“Standing at the side of the road waving it about is not going to end well.
“London is full of vermin.”
The Met Police have been approached for comment.
