I got a triangle frame bag for a Brompton - what is it good for?

[Time Waster]

I commute only so will never tour or leisure ride on my Brompton. It is for mixed mode commuting only. So with this in mind the suggestion on the manufacturers sites I have seen is for an inner tube and mini multi tool. I will not do that because if it is broken or gets a puncture I will just fold it and get to my train by another way with it folded. Then I fix at home in my own time.

I hoped my cable lock would fit in or my lights but they do not. So I am stuck for what it could be used for. Any ideas??

I always carry a cover for the folded bike in case it needs to pretend it's a run-of-the-mill piece of luggage.

Inner tube and a tool kit can both be stored in the frame.

The Brompton tool kit IMO is the best solution and isn’t that expensive if you priced up everything individually

Sandwiches cut into triangles...

That depends on the shape of your triangles. Only works with rightangle or scalene triangles with one diagonal cut. I prefer the isosceles sandwich cut with two diagonal cuts on a square baked loaf. I have a set square just for the job too. I am fussy like that.

£65-70 for a Brompton toolkit is expensive when you have tools from other bikes that could be used omn a brompton too. It is a good storage solution but I do wonder if you'd go with the same tools without the neat storage. I heard tdshey are not great.

The other POV is that the Brompton iss really not the bike for fixing at the roadside. The whole point is that it can be folded and taken on public transport or other transport methods. Apart from some very quick fixes who really does fix their Brompton on the commute versus at home in the warm and dry?

I have had a few mechanicals that I could get sorted enough to get me to the station and the train home. I have had one front wheel and one rear wheel puncture. Both meant I rolled or carried it to the nearest train station or bus stop that suited me and took it home. I suspect most commuters do similar with Bromptons. I do know tht the first time I got a rear puncture I was not ever going to take the wheel off or patch it up on the side of the road in the wet and cold that it happened in. The front I was messed up as it was a missed pothole incident and it turned out the cut inner tube was not the only thing broken. The cross tyre dent was also worrying but after inflating it with a new inner tube later it seemed ok. Instead of a repair I tried to carry it to the station and a guy came past and gave me a lift to the station.

I think leisure riders and tourers of Bromptons the toolkit might make more sense though I do think those users would be better off supplementing with some other things or even making their own versions up with tools they prefer. I think I saw a few people and companies selling 3D printed cases to take tools and hold them insde the frame or flexible ones that do similar. Check out etsy i think too. Plus a few youtube videos with homemade kits.

Toblerones?

A lightweight windproof or waterproof for changeable conditions.

Toblerones?

Only when cut in half. Isosceles and equilateral triangles aren't a good fit you need right-angled or scalene triangles. Not a common shape for chocolate. Although I'll get the knife out and practice cutting the Toblerone until I get the shape right. I might take a lot of Toblerone to get right!

By the time you’ve bought all the individual items and the 3d printed case, you’re not far off the price of the Brompton tool kit which is a beautiful piece of design

But the point is you get the tools you want not Brompton want to sell you. Or more likely just use the tools you already have and just buy the case to fit it into the frame with which then makes it cheaper. I also saw people sort their own fixings into the frame too which is even cheaper. There are a few Brompton tool kit videos out there about people making their own up cheaply or not cheaply. The key point it making it your own at your own budget and preferences.

My preference is not to have one and use the principle of the Brompton fold and public transport to get home to fix it. I am tired of having to fix punctures, gearing issues, broken chains or brake issues in the cold, wet and windy commute. Basic fixes I can do in less than a minute or two without tools I do, much more and I would not be fixing it. I think the fold to use on public transport, taxis, etc. is the point of it for the commute so why not if it needs fixing. Once at home it can go on the bike stand and gets fixed with proper garage tools in a warm garage with lighting and no rain or wind.

Most of us are familiar with the Ikea Dimpa bag and the Kalax storage option. The small Ikea 'double ziplock' bags for food storage are also ideal for storing puncture repair items, small tools, etc., in the front part of the frame used for the Brompton tool kit! I am sure someone on the Ikea design team has a Brompton.
