Compatibility

Will this fit on my Brompton A Line / B75?

Short Answer: Yes

Since 2021 all Brompton folding bikes come as standard with a front carrier block pre-fitted - with the exception of the A Line / B75, but this can be fitted later to allow the carrying of the Brompton range of luggage

Will this fit on my Brompton Electric?

Short Answer: No

The Brompton Electric uses a different front carrier block which also contains the electronic controller for the bike. The block and bags are different

Will this fit on my Brompton T Line?

The T Line uses a different front carrier block mount - it is fundamentally the same but with longer mounting bolts
The Brompton code for the T Line front carrier block is: Q102716

Will this fit on my Brompton G Line?

Short Answer: Yes

Although the G Line comes as standard with a front carrier block (the same one as the C Line and P Line) there could come a time where you need / want to replace it - this will fit perfectly

Brompton Front Carrier Block Frequently Asked Questions

What weight can I carry using the Brompton front carrier block?

Brompton say that you should not exceed 10kg of front luggage

Bear in mind that the total weight carried by the bike should not exceed 110Kg - including the rider, the front carrier luggage and any rear rack luggage

I am trying to fit this but the bopts are too big for the holes on the frame

Short Answer: You need to remove two grub screws before fitting the block

When the Brompton is manufactured and prepared for painting, two grub screws are installed where the front carrier block fits to

This means that when the bike is painted the two holes are not filled with paint

These two grub screws then need to be removed - using a 2.5mm Allen key / hex wrench - as part of the front carrier block installation

I have lost part of the fitting kit - can i get a replacement bolt / parts

Short Answer: Yes

If you lose a bolt (for example) ...

There is a front carrier block fixings only kit available with just the mounting bolts / plate and self tapping screw

How do Brompton describe the front carrier block?

This is the block as described below by Brompton:

Quote: Brompton front luggage options are based on the Brompton 'Front Carrier System'. Luggage is attached via a frame that latches securely onto a tapered block. It takes a second to attach or release your bag and the load is attached directly to the main frame - with little effect on steering.
