BMX Frames – Geometry, Materials & Riding Characteristics at a Glance
The frame is the core of every BMX bike. It defines not only the weight and stability but above all the ride feel and geometry of your setup. Whether it’s for street, flatland, park or dirt – the right frame makes all the difference.
In our BMX frames category, you'll find high-quality models made from HiTen steel or CrMo steel, with geometries optimised for different disciplines. From lightweight flatland frames to robust street setups – there’s something for every rider level.
Key dimensions on a BMX frame
BMX frames rely on precise geometry – it affects handling, balance and control:
- TT (Top Tube length): The most important dimension – typically 18", 20", 20.6", 20.75", 21.25", depending on body size and riding style.
- CS or RC (Chain Stay / Rear Center): Shorter = more agile, longer = more stable for jumps.
- HT (Head Tube angle): Steeper = quicker steering, flatter = more control.
Materials & construction
- HiTen steel: Budget-friendly, ideal for beginners – heavier but strong.
- CrMo steel: Lightweight, durable and high-quality – great for ambitious riders.
- Aluminium: Lightweight & corrosion-resistant – ideal for entry-level setups.
CrMo is especially popular with pros thanks to its strength-to-weight ratio.
Head tube, dropouts & bottom bracket details
- Head tube: Integrated or Looseball compatible – check our WORK-SHOP videos for installation:
- Dropouts: Usually 14mm or 10mm – crucial for compatibility with hubs and pegs.
- Bottom bracket shell: Most frames use Mid BB, while some custom builds use Euro BB (threaded).

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.
Great service, fast delivery, no problem exchanging. Top company!
Great bikes at fair prices and great customer service!
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.
Very friendly and excellent support. @KHEbikes - thank you very much
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.
Beautiful, robust bikes and absolutely top-notch customer service. Very helpful both by phone and email, and there's a solution for every issue! It's great to still have such great and positive shopping experiences every now and then. Thank you, dear KHEbikes team!
Very quick, uncomplicated help. My contact, Mr. Göring, was very nice.
Fast, competent, and friendly. Best service
the attention is good even if you have a problem they support you so that everything goes well
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!
Top customer service, super clear homepage :)
Top-notch advice! Always happy to come back!
Super fast delivery, great customer service, and very satisfied with the BMX. Thank you very much!
Very friendly and very helpful. I contacted them via email and received a prompt response with good advice and a purchase recommendation. I'd be happy to come back.
