Depends on a number of things: -how hilly is it -how windy is it, and is it a head-or a tailwind -is it on a road, or more of a track -does the rider have to carry any gear -how fit is the rider and more Assuming decent roads a really strong rider would be able to make it in about 20 hours, and quite a few would manage to finish within 30 hours.
Depends on the human, the bike, the terrain and the weather. I could probably do it on my commuter bike in 8 hours of riding, assuming good weather and a flattish course. A group of more dedicated riders on betters bikes should be able to polish it off in 6 hours. Someone else may need 10-12 hours total.
Depends on a lot of things. A fit rider can do 20 MPH for several hours under reasonably easy riding conditions, so if the rider can do 10 hours/day you're looking at two weeks solid riding.
This would be rather uncomfortable and quite demanding, so if you're planning a ride I'd suggest splitting it into 3 weeks, doing about 150 miles/day.
That would be reasonably doable assuming you're travelling light, and you'd even get a couple of rest days.
If you need to carry camping gear, use poorer roads or just want an easier time, make it a 4 week journey.
There's virtually no way of telling, there are too many unknowns in terms of what the road conditions are, what kind of bike you're thinking of and how fit and old the rider is. A fit rider could probably do it in 6 hours, if conditions are nice.
it obviously depends how fast you can ride a bike and how long you can go without stopping
That depends on your speed.
Er, it's 60 miles, or 96 kilometers. what else would it be?
Since a stationary bike doesn't move, there's no way it can travel 20 miles. Now, if you're asking how long it would take to ride twenty miles on a bicycle, it depends on speed, wind, and other factors. Typically a bike maximum speed is about 20 miles per hour. So it would take about an hour to ride 20 miles on a REGULAR moving bicycle.
It depends on how fast you can ride a bike!
24 minutes
about 2 hours
A bike Trail is up to 1-10 miles long.
20 minutes.
Three hours (30/10 = 3).
12 minutes.
how long does it take to go 45 miles at 20 mph
