Little bike, BIG attitude
They’re tired of “kid stuff,” and they’re ready for a new adventure. Sesh offers uncompromised professional quality and deliberate design choices tailored for the next generation of shredders. Built with a durable steel frame and reinforced with thick dropouts, Sesh has the same resilience your grom brings to every ride. At its core, this entry-level BMX bike packs a punch with professional-grade features, including a 3-piece crank, 25x9T compact gearing, and axle pegs – just like their favorite pro’s bike. Thoughtful safety features like extra-long handlebars, a reliable & snag-free U brake, precise threadless steering, and wide, shock-absorbing tires keep their ride safe and nervous parents at ease. Sesh is edgy, exciting, and undeniably bad@$$. It's not just what kids want; it's what they'd choose for themselves.

How to measure my inseam for a bike

Your inseam can help you find the perfect sized bike (measuring it properly is similar to pant inseams but measured a little differently). Here's how they work:

  1. Stand upright with your feet 6-8" apart.
  2. Using a tape measure or tailor tape, measure from the bottom of your foot to the top of the inside of your leg.
  3. Compare your inseam measurement to the standover height of the bike. You should have about an inch of space between your body and the top tube.
