On board the young Dutchman's fully dialled Flybikes rig

From my perspective, Sem Kok appeared out of nowhere.  At the Vans BMX Pro Cup 2017 in Malaga, Sem showed up and rode really well.  From there, he was everywhere that summer – on his bike seemingly all around Europe, his name popping up on various Instagram feeds from trails jams and the like, always riding like a true boss.

At the Vans BMX Pro Cup 2018 in Malaga, Sem rode REALLY well.  Incredibly well, actually.  One of his runs was a major highlight of the weekend for me – especially when it finished with a 180 over the jumpbox.  Like I said, true boss.

With all of that goodness and plenty more great riding in between, plus of course being a nice guy that people get along with and want to support, Sem earned himself pro rider status with Flybikes.  As Sergio Layos is no doubt one of Sem’s favourite riders, it must be quite an honour to be representing the same brand and running Sergio’s signature Sierra frame.  Here’s a look at Sem’s current rig…

– Where has this bike taken you so far?

2019 has been great so far! I went to Estonia, Florida, Australia, and little trips to Belgium and Germany.

– How do you like it set up?

It took me a while to get used to, but now it feels amazing!

– Any old parts or all fresh?

No old parts, all new from the ground up.

– What’s your favourite thing about this build?

I would say I’m really into metal pedals so I’ve been loving the Fly Ruben aluminium pedals.

– What’s coming up next for you?

I’m planning on doing a trip to Germany for the second stop of the Vans BMX Pro Cup and a contest in Cologne, Germany.

– Any final words?

I wanna thank my family and friends and also the companies that stay behind my back to help me out to get on the road! Flybikes, Oakley, RockNrolldistro, Soulcyclebmxshop.
