Kim Kardashian is gonna have to keep up with Saint West.
The 10-year-old made his Instagram debut on Aug. 1, showing off videos of his new purple e-moto bike. In one clip, the tween popped a wheelie while riding his bicycle around his neighborhood.
Underneath an Aug. 3 Instagram Reel where Saint showed off the specs of his new ride, his mom—who shares Saint as well as North West, 13, Chicago West, 8, and Psalm West, 7, with ex Kanye West—lent her support to her eldest son’s latest passion project.
Indeed, Kardashian kept it simple, commenting with a single purple heart emoji to match her son’s bike.
This latest ride isn’t the only adventure that the mother-son duo has embarked on recently. In fact, Kardashian brought all of her kids on a lakeside excursion to Idaho alongside boyfriend Lewis Hamilton in mid-July.
Posting a selfie with Hamilton and Chicago in front of a pine tree, the 45-year-old wrote in a July 13 Instagram post, "Summers at the lake with my favorite people."
And Saint isn’t the only one of Kardashian and West’s kids who have recently made their Instagram debut. His older sister North launched her own page in December 2025, showing off her alternative style with a photo of herself in a black skirt, graphic t-shirt, bedazzled boots and statement jewelry.
Holding up a peace sign in the snap, she captioned her pic, “first post.”
While their older kids are just beginning to explore social media, Kardashian and West have previously been at odds about allowing their kids to post.
“I know y’all don’t respect fathers and the idea of family and the media tries to promote something,” West, 49, said in a 2022 social media video. “I said, ‘I’m not allowing my daughter to be used by TikTok, to be used by Disney.’ I have a say so.”
Still, it seems like the former couple—who split in November 2022—have reached an agreement about their kids’ public pages, as Saint continues to enthusiastically post about his bike. Keep reading to see how the eldest Kardashian-West son has evolved throughout the years…
