Back in the mid 2000s I used to ride a 2 miles, 45 minute train, then 7 miles to work, and back, 5 times a week on a Bromptom. No problems, it was ideal.

I then moved and I lived at one end of the Central line in Essex, about a 1 minute walk, and worked a similar distance in West London.

Took about 55 minutes for the train to go, always got a seat in both directions.

However during summer I would ride on my Bromptom one way in the morning two or three times a week - took about 24 miles, or 2 hours, I'd then fold it up and take it home on the train.

My next move was too far to ride (45 miles each way), and less than a mile from the station at each end so didn't do much commuting riding then, and I moved to be a home worker in 2011, but I still ride my Bromptom around the country lanes. Occasionally think I should upgrade to something with more than 3 gears (it's relatively hilly where I live).

The bike itself I think cost £520 back in 2005, a new one of the same model is over £1k now, not sure what the second hand value is
