Hi im looking for a brompton alternative. Its just a bit too expensive for me so i was looking for something i could use and maybe think if i should get a brompton eventually. Preferably something that folds small and fairly light.

Any Folder. Or none apart from the Brompton - depends. If there was an alternative that was light, as compact, as good and way cheaper - do you think Brompton would have sold more than 1/2 a million of their bikes? All cheaper alternatives differ in one way or another and only you can judge what is necessary or important to you and what would be a fair compromise for your needs (if there is one). If a new one is too expensive (which would be totally understandable) - why not look for a used one if a Brompton is what you want? Possibly better than spending what you have on a bike that you don't want and this way vaporizing the existing funding basis to get one. If you look at the bike as a way of transport you will probably discover that the Brompton is in no way expensive but saves more money than is costs relatively quickly compared to what you have to spend with alternative ways of transport. If that's not true for you maybe you don't need one but just want one (which again would be totally fair).

Dahon EEZZ - a bit smaller than B'ton. Weighs less I think; some folks complain the
folding is more complex than B'ton. Discontinued; can be found for US$600.
Dahon Curl - copied B'ton's fold, so similar in size. Price & weight is about the same.
Chedech - copied B'ton's fold, so similar in size. At over US$2,000; more than standard
6 speed B'on but weighs less. 6 speed titanium/superlight Bi starts at $2,400 I think.
Bike Friday pakiT can be custom ordered; frame size, gearing/speeds, components(belt/chain/
der./IGH/etc.). Usually cheaper. Folding is more like dismantling.

There's a Xootr Swift on SF Craigslist right now for $295. Would be a great choice!

Yes i guess you are right. Buy once cry once. Haha

The Brommie is not necessarily the bike for you if you haven't tried it yet. Can you actually test ride one, maybe from a dealer, renting one, or otherwise?

Every time I see that a Swift is for sale somewhere I cry a little inside,...

...because you want it or because you can't understand why they are selling it?

Both,...I miss my Swift. I know it's not currently available around me, and whenever I do see one available, I don't have the resources to get it.

Google for 3sixty Brompton clones. They are much cheaper and lighter than UK Bromptons.
