Had a Birdy Blue about ten years ago - very comfortable bike that gave a good ride for a small wheeled (it had a 16inch rim conversion 'cos you couldn't get good tyres in the R&M 18inch size then) folder. Commuted on it on train, did some club runs and even the odd hilly audax. Very reliable.
Then sold it and got an Airnimal with a mix of DA, Ultegra and 105 kit. It was one of the early ones and the seat mast snapped twice. Airnimal changed the design and I didn't have any moe trouble with the seat mast. But a couple of years ago the main frame snapped in two. So as soon as the warrantee replacement came I sold it, having lost confidence in them even though I'm sure that it would have been fine.
The Airnimal has a nice ride - much like a light tourer and again I used it for commuting, club runs and audaxes.
Now I'm looking at using the trains to get around ago for various reasons so I was in need of a new folder. Have tried a Brommie but wasn't too keen on the ride (I like to honk out the saddle a lot). Dahon had some nice offerings at good prices but I'd heard that some replacement parts are hard to get and that the wheel build quality isn't always that great. Tried a Mezzo - seemed like a nice ride but they only had the 4spd and the bikes are too new to find one second hand.
So, I decided on another Birdy and picked up a used but good condition one on the CTC forum. This one is Birdy Red. It had a comfort stem, which I've customised with the help of Black Dog Bicycles (
topdog@blackdogbicycles.com) in the US. It now has a standard road ahead stem fitted to the top of it which makes the reach, and thus the ride, much better.
Next I will be looking at extenting the gear range for when I go touring in the hills.
