M Stop for Brompton

M Stop for Brompton

Makericks3D M Stop

Our M Stop brings you the P Line mid-stop disc feature to your A and C lines, enabling users to conveniently fold and roll their bikes with the seatpost extended.

The M Stop has been custom designed to fit all Brompton types - R, L and E.

Specially for Type E Brompton (no mudguards and no rack), it contains additional feature of helping to balance the bike so it does not tilt to the side, preventing your bike from falling easily, saving you from heartache and/or money for repairs.

The M Stop has been tested on touring rides and does not get dislodged easily on bumpy rides.


We have the new Type V2 that caters  to Brompton L models with mini rack, such as those offered by 3rd party brands like Ti-Parts or H&H.

Type V2 is also well-suited for those on R and L type model, but planning future rack modifications while retaining the mudguard.

It is important to note that, for this purpose, allowing the M Stop to conform to the shape of your seat post will be necessary. Initially, some resistance may be experienced, but over time, the fit will naturally improve.

For those who prefer an immediate and seamless fit, we recommend opting for the respective standard types (L,R).


✔  Push or carry your Brompton with your seatpost up easily, no more cumbersome straps needed!

✔ intuitive design that is easy to insert and remove, yet stays secure in place even on bumpiest rides

✔ highly durable material that is flexible and resistance to tears and abrasion

✔ Bonus feature to help balance your bike if you are on a Type E (no mudguard, no rack)


When you push your seatpost down, you should feel alittle "resistance", indicating the bike fold locking position. Continue to push it for approximately another 3 cm and you should go past the "resistance".

This resistance feature is designed to help you to know when your seatpost is slightly beyond the M Stop without having to bend down to check. You can now push or carry your bike with the seatpost up.

Please ensure your bike is fully folded half fold or opened-up before pushing down seatpost. do also check that types are pumped up to the necessary psi

Very well thought out product

Bought two different M-Stops for two different C-Lines.. As described, the M-Stop does its job very well. Once the seatpost is locked in properly, my bike does not unfold while rolling, no matter how much I try to shake it. When fully folded, it’s no longer wobbly. Alice did an amazing job here with this product. I am very pleased to recommend it to all Brompton C-Line owners. ��
