KHE PRO BMX Bikes – High-end freestyle models for maximum performance
The KHE PRO BMX Bikes are the flagship models of our brand – built for riders who demand the highest performance from their BMX. Whether it’s park, street, pump track or dirt: a PRO model offers you maximum stability, precise geometry and high-end components that you’d usually only find on custom builds. Models like the KHE SPECTER V2, Cirrus FC or Silencer impress with uncompromising spec – ready for true pro-level action.
Every PRO bike comes with a 100% CrMo frame, butted forks, female hubs, CNC machined stems and 48T hollow CrMo cranks. The FC models such as the Cirrus FC or Silencer FC are also equipped with a Freecoaster hub – a favourite in street riding for rollbacks without pedal movement. The patented AFFIX Rotor allows full 360° barspins with a functioning brake – perfect for park and flatland.

My son is thrilled with the design of his BMX bike. After I had trouble assembling it (especially the brakes), I contacted KHEbikes. Absolutely fantastic, friendly, and fast service, which solved the problem! I'm truly thrilled and can only recommend KHEbikes! 5 stars ⭐️⭐️⭐️⭐️⭐️

My previous review was worse. The reason for this is that I've encountered a lot of poor providers in the past, and so I simply share my negative experiences. I was contacted immediately after my first review, which I personally thought was really great. It immediately showed that the customer is their top priority. A big thumbs up for that.

Very pleasant contact, I'm very impressed with the staff. The purchase process is easy, and the description is accurate. The order arrived very quickly, but unfortunately, there was some shipping damage, but it was replaced without any major problems.

Thanks to excellent advice over the phone, we were able to order the right spare parts for our son's BMX bike. They assured us of prompt shipping, so he was able to happily use his bike again the following week. Many thanks to Mr. Stubenrauch for the great advice!

Over the years, we've had nothing but positive experiences with their products and service! Unfortunately, no race bikes or parts, which would make the product range perfect. Highly recommended!

Very friendly contact, excellent advice. Even a question about the assembly of the BMX bike I purchased was answered the same day (Sunday!). That's how you retain customers long-term. I certainly won't have ordered the last bike from you. 😊 Thank you very much.

Despite the remote diagnosis, we received excellent advice. After a few emails and photos back and forth, the problem with the bike was identified, and we were able to fix it ourselves. Our son is incredibly happy to be able to ride a BMX again. Now that's what I call customer service! Very friendly, dedicated, and competent!
