The Unilever sponsorship deal will be announced at a press conference at the Revolution Event, Manchester Velodrome, on Saturday night.
"The new sponsorship will help British Cycling raise the profile of cycle sport in the UK - from a grassroots level to supporting the development of current and future cycling stars," said a statement from British Cycling.
The statement did not name Persil as the sponsor - contracts were only inked yesterday - but the entry of the brand has been an open secret among some bicycle P&A suppliers who have been quoting for 1000+ kid's bikes and 10 000+ jerseys being lined up for on-pack giveaways on boxes and bottles of Persil.
The bike company which is involved is Trek UK and the 1000 giveaway bikes will be co-branded Trek, Persil and British Cycling.
In the summer, there will be supermarket car-park promotions of Persil's link-up with cycling.
As well as marketing cycling to children, the Persil/Trek/British Cycling deal also involves supporting a high-end cycle team.
