SomeGuy said:Also while riding 100k each day is certainly a lot, I dispute that it would add 4 hours to travelling times. A fit cyclist would probably take around 2.5 hours each way. To drive or train the same distance would be take 1-2 hours, so in fact the ride would probably add 1-3 hours (I'd put money on it being closer to one), not 4.
I would suspect that the time to work would very much depend on the route that you were able to take.
I ride to work 2 days a week, 2 on the train and drive one. I should also point out that I leave at the same time each day, 0600.
To work is 38km and takes me about 1hr 10 min on the bike, about 1hr 30min by train and 1hr by car. The interesting part is that I ride the exact same route I drive.
Going home I am normally going to a mates place so I can extend the route so I do about 50-60km on average. The thing is that this takes me about 2hrs; because I have to climb some hills to get home (namely one big one which is 3.5km long at a average of 4%).
I will admit that flying down Cross road at 35+ km/hr and seeing the cars sitting still always makes me smile. I have even gotten abused by a ****** in his V8 monstrosity because he was going slower then me.
Now I am not really fit, but I do over 250km a week on average. Not everyone wants to do that much though.
I am a firm believer that terrain would be one of the key factors in whether people would consider using a bike to commute to work. Well I have put my 2c in.
