Here is Granville with his Brompton block.
The block mount was made of half a bit of steel tube with a bit of steelwelded to the front and two M5 holes drilled and tapped into it. The whole thing was then sprayed in primer and slipped into a bit of old inner tube to save damaging the valuable 'Pannonia' and 'Made in Hungary' transfers on the headstock tube. It was then strapped in place with two decent quality hose clips.
Granville and Tiddles can now share front luggage!
Tiddles didn't escape attention. Following a ride this morning I made a rear bag for him.
I used a scrap of left over roller black out blind material, as used for the Ratrike panniers and trailer.
The material was sewn into a tube and then flat sewn at the bottom to keep the shape narrow. The top was then rolled down and webbing straps sewn in so it can be rolled and clipped like an Ortlieb bag.
Two toe clips suspend it from the saddle and a double sided velcro band keep it attached to the seat tube.
By releasing the velcro Tiddles can still be folded with the bag being a minimal addition in size.
The top roll fastening can also clip around the seat tube to keep things snug.
This is the bag with waterproof coat, gloves, buff and a few tools in it.
There is also a dedicated Haribo pocket inside near the top as a reserve fuel tank.
