Prince Archie’s Birthday Gift Revealed! See Prince Harry and Meghan’s Sweet Thank You Letter

Local bike shop owners gifted Prince Archie a bike with training wheels — plus flowers for Meghan

Prince Archie got royal treatment on his 4th birthday — a bike, hand-delivered by the local shop owner himself.

As the world woke up on May 6 prepared to watch the coronation of King Charles, the owners of Mad Dogs & Englishmen Bike Shop in Montecito, Calif., were thinking about another member of the royal family — Prince Archie. Shop owner Jennifer Blevins told PEOPLE that her British partner and shop co-owner, Martin, spontaneously wanted to give Archie, the son of Meghan Markle and Prince Harry, a special birthday gift.

“He went and he got one of our little specialized kids’ bikes — they’re really nice little bikes — and he’s like, ‘This one’s perfect, it’s got training wheels,’” Blevins told PEOPLE. “And so he went and got some birthday balloons, and he got some flowers for Meghan and a birthday card, and he said, ‘Okay, I’m gonna bike over and take it to their house.’”

Once he arrived, Blevins said security emerged from behind the gate of the home, asking Martin if he had received an invitation from the royals.

“He said, ‘I’m just a British business in town that wanted to give Archie a gift,’” Blevins laughed.

After running an on-site background check on Martin, security allowed him to leave the gift — flowers, card, balloons and bike, Blevins said. Flash forward a month later, said she got a surprise delivery to the shop on Wednesday.

“A courier came by our little shop on Coast Village Road and he dropped off that letter,” she shared with PEOPLE, referring to a thank you note sent from Meghan and Harry.

“I was making a joke, I said, ‘It better be a thank you letter,’ and it really was!” Blevins said. “I wasn’t expecting that. I had no idea.”

“It was so thoughtful because, you know, they took the time to write something personal and not just a generic thank you,” she added.

The letter from Harrison Colcord from the Office of Prince Harry and Meghan was posted to the bike shop’s Instagram.

It read: “On behalf of Prince Harry and Meghan, The Duke and Duchess of Sussex, please accept their sincere thanks for the thoughtful gift you sent to Prince Archie for his fourth birthday. The bike has brought much joy, and is most appreciated by the family. They asked that I convey their gratitude at the lovely surprise.”

Blevins said she and Martin — and the entire bike shop staff — were in shock by the kind letter. Noting that it was an “impromptu” and “very sincere” gesture to give Archie the bike, no one expected anything in return.

“Every celebrity in that town has bought bikes from us, and they all come through there,” she recalled. “None of them sent a thank you letter.”

Blevins told PEOPLE she and Martin hopes the gift leaves a mark on the family.

“His little sister Lily can enjoy it too as she grows, it’ll be one that both of them like,” she said.
