How do I replace BMX cranksets and what tools are needed?
- Allen wrench: to loosen the crank arm bolts, you'll need an Allen wrench that matches the size of the bolts. Crank puller: A crank puller is needed to remove the old crank arms from the bottom bracket axle.
- Wrench or special bottom bracket tool: Depending on the type of bottom bracket you have, you may need a wrench or special tool to remove the bottom bracket.
- Torque wrench: A torque wrench is useful to tighten the crank arm bolts to the correct torque to prevent damage.
- Preparation: make sure your BMX bike is securely on a bike stand or upside down. Remove the front wheel to gain better access.
- Removing the pedals: Use a wrench to remove the pedals from the crank arms. The left pedal has a left-hand thread, so you will need to loosen it clockwise. The right pedal has a right-hand thread, so loosen it counterclockwise.
- Removing the crank arms: Use the crank puller to remove the old crank arms from the bottom bracket axle. Insert the crank puller into the threads of the crank and turn it clockwise to loosen the crank. Repeat this step for both crank arms.
- Bottom Bracket Removal: Depending on the type of bottom bracket you have, you may need to remove the bottom bracket. Use the appropriate wrench or special tool.
- Installing the new crank arms: Place the new crank arms on the bottom bracket axle and tighten them with the torque wrench to the torque recommended by the manufacturer. Make sure the crank arms are tightened evenly.
- Attaching the pedals: Screw the pedals back onto the crank arms. Remember that the left pedal has a left-hand thread and is tightened counterclockwise, while the right pedal has a right-hand thread and is tightened clockwise.
- Inspection: Check the entire assembly to make sure everything is secure and tight. Check the pedals, crank arms and bottom bracket.
- Test Ride: Take a short test ride to make sure everything is working properly and nothing is coming loose.

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.
