SmarTrike has designed ten limited edition Royal tricycles to mark Prince George's first birthday.
The firm is also launching #RoyalRide, a nationwide campaign that will see the likes of bloggers and celebrities head 'out and about on their smarTrikes wishing Prince George a happy birthday'.
The campaigna also gives families the chance to win one of the special trikes.
TV personalities Michelle Heaton and Laura Hamilton and their children joined the first #RoyalRide trip around central London on some limited edition trikes.
SmarTrike's Royal Trike comes with a patented Swivel Wheel and Touch Steering and transforms in four different ways from ten months to three years and beyond.
Any family who wins one of these tricycles will be one of just ten people in the world to have one.
"So many parents choose a smarTrike as their baby’s first birthday present, that we wanted to celebrate by designing one for Prince George’s first birthday," said marketing communications and PR manager Aviva Barach.
"Our team have really enjoyed creating these trikes, and we hope they catch the eye of the Royals."
