The 35-year-old male was treated for head injuries following a collision with a car at 6.38am, but medics were unable to save him and he was pronounced dead a short while later.
Police say a post mortem will be held in due course.
The tragedy occurred on the north side of Battersea Bridge, at the junction with Beaufort Street and Chelsea Embankment.

The deceased motorcyclist was on a Honda bike when he was in collision with a Toyota Prius on Wednesday (October 4).
The driver of the car stopped at the scene, said police.
The incident resulted in the closure of several local road, including Chelsea Embankment westbound from Albert Bridge and Battersea Bridge itself, with police diverting traffic and advising all motorists to avoid the area if possible.
Detectives from the Serious Collision Investigation Unit and Chelsea Police have launched an investigation.
No arrests have been made and enquiries continue.
