2 miles to the station, 2 trains (30 mins total) and 1.5 miles the other end. I have a Brompton.
If I had a fixed bike/MTB (I could go through some parks and off road a little), it would be 11 miles from home to work.
However, I bought the Brompton because the company I work for is going through a lot of changes and I think I'll be looking for another job later this year - and it is very likely I will end up back in Central London again (35 mins to Waterloo).
If the Cycle Superhighway out along the A4 Great West Road at Brentford/Hounslow ever gets built I might try to cycle all the way into Central London, as I am only a couple of miles from where it is supposed to start. There are currently decent enough cycle lanes along the side of the A4, but they completely disappear at the busiest part, where it goes under the M4 and they all join together with lots of slip roads - and then reappears somewhere on the Chiswick High Road.
The bit where there is no lane and I wouldn't really want to ride goes right past the Brompton factory ........
