The man then grabbed the bike and demanded the teenager got off it.
He then took the bike and road off on it towards West Row. The teenager was not injured.
The bike is described as a Cannondale Trail 8 bike with multi-coloured rainbow pedals and a boom speaker.
Police are asking for anyone with information about the incident to contact Bury St Edmunds CID, quoting reference: 37/48899/21
