With the promise of more regular first XIII rugby Sykes moved south to join the London Broncos in a permanent deal in August 2002.

Sykes soon settled back to life in the capital and representative honours were gained with an appearance for England "A" against New Zealand in October, followed by a place on the successful "A" team tour to Fiji and Tonga.

However he made a comeback towards the end of the season after initially being ruled out for the entire campaign 2005 was a record breaking year for Sykes.

On 27 February against the Wakefield Trinity Wildcats, Sykes kicked 12 goals from 12 attempts to break a 17-year-old London club record.

Sykes, who made his Great Britain début earlier this season, left Bradford on loan in 2002 to find first-team rugby.

Boss Steve McNamara reckons he has picked up a rare talent, and added "I'm absolutely delighted to have secured an outstanding English centre and thank the board for making the deal possible".

In the 2012 season Sykes was loaned out to fellow West Yorkshire club the Wakefield Trinity Wildcats after only playing 2 games for Bradford Bulls.
