The 20-year-old woman collided with a HGV outside Aldgate East Tube station as she rode along the Mayor’s CS2 cycle superhighway on Whitechapel High Street.
A police community safety officer at the scene claimed the hire bike was thought to have been laden with shopping - which may have caused her to lurch into something and be thrown into the path of the lorry.

It's not clear exactly who collided with who.
