Boy Kitchen Easy Fold Clamp for Brompton

The kit comes with 2 clamps, 2 screws, 2 springs and 2 nuts
My friend Marlowe, who shuttles to and fro Thailand, was kind enough to get me a pair of Boy Kitchen's Easy Fold Clamps for my Brompton during his last visit there. For those of you not in the know, the Easy Fold Clamps replace the standard clamps of the Brompton's two hinges. You see, the problem with the stock clamp is that it rotates when you loosen the lever. It can get irritating when you fold or unfold the bike. Because it is loose, you have to hold the clamp in place when you tighten the lever to re-attach it to the bike. (For those non-Brompton owners I am sorry if you did not understand my description--I don't know how else to explain it)

Boy Kitchen's aluminum clamp avoids that annoying situation by making one side of the clamp rise higher than the other. The redesign results in the Easy Fold clamp staying in place when loosening or tightening the lever--saving you time and the trouble.

Silly me, I intalled the Easy Fold clamp as is. And as a result, I had a hard time turning the screw because it didn't come with its own lever. I thought to myself, "I don't think it's supposed to be this way." Luckily, I found Boy Kitchen's YouTube video on his product. Apparently, you can pop out the black lever off the stock screw with a hammer and then transfer that lever to the Easy Fold screw. So that's what I did. 

Afterwards, I installed the nut at the end of the screw to stop the lever from turning when the Easy Fold clamp is unfastened from the hinge.
Final product on the Brompton's hinge.
Voila! Installation complete!
No more wildly rotating clamp to deal with when folding or unfolding my Brompton! I wish Brompton makes these their stock hinge clamps!

PS: The two clamp set does not come cheap though. Boy Kitchen prices a pair at THB 1,850.00 or US$60.00. (May be its expensive because it is not mass produced and he fabricates it himself.)


  1. Ouch $60 - that's pricey.
    I like the concept, but I can not say I am disappointed with the Brompton part that came with the bike.

    Peace :)

    1. You are right, sir. If it doesn't bother you, then you don't need this.

  2. I'm in the US. Where exactly can I purchase these from? Awesome blog by the way.

    1. Thanks, Jason! This product you can get from the maker himself. Look him up on facebook. He goes by the name Boy Kitchen Bicycle Modify.
