The first cycles which will be used in a bike-hire scheme in London have come off the production line in Canada.
The cycles will feature three-speed gears, a bell, a basket and are being fitted with dynamo-powered lights.
The 6,000 bikes, which will be rolled out in London from 30 July, are being produced in a factory in Bagotville.
People will be able to access the bikes 24 hours a day from 400 docking stations in nine boroughs and several Royal Parks in central London.
Cyclists will have to pay a £1 "access fee", but the first 30 minutes will be free.
It will then cost another £1 for up to an hour, £4 for 90 minutes, £6 for two hours and £50 for 24 hours.
TfL hopes the hire scheme, which emulates similar schemes in Europe, Montreal and Boston, will generate an extra 40,000 cycle trips a day.
London Mayor Boris Johnson said: "What we are creating is not just a cycle hire scheme, but a new form of public transport of the greenest and healthiest of kinds.
"It will become the cornerstone of the cycling revolution in the capital and will, I'm sure, convert legions of people to the pleasures of pedal power."
The cycle hire scheme will be available in Camden, Hackney, Lambeth, Islington, Kensington and Chelsea, Southwark, Tower Hamlets, Westminster, City of London and the Royal Parks.
