If I bike 6 miles a day, will I see a difference over time?

That depends on how you take care of yourself.

1) Your skin is going to be darker if you do not have proper suntan on.
2) You can easily fall sick if you are not properly attired for the ride.
3) You can get stressed out due to pollution, foul weather, issues with bicycle, bad roads/terrain and heavy traffic, especially if, you are not cycling in a bike friendly district or country.



So, before you start, made sure that the routes that you are taking are safe for cycling. Take public transport part of the way if the distance is too much to bear (in the beginning). Check what the weather is like to be properly attired and UV protected.

To cut unnecessary stress, check out these points to make sure that you are really ready to cycle.
Ready To Ride?

Once you have got it right, after cycling for a period of time, these are the changes you will see.

1) Your buttock will not ache as much as you develop muscles there.
2) You will sweat it out as you cycle and that will make you lose some weight.
3) You will build up your cadence and find it easier to cycle as you get more competent with your gears.
4) You may find new friends cycling the same route.
5) You can see more clearly what is going on around the district you are cycling through.
6) You will build up your stamina and endurance for other physical activities.
7) You will consider using your bicycle more often to run errands.
8) You may develop a sense of adventure and want to explore new routes that only a bicycle can take you. Maybe even a trip outstation or overseas on your bicycle.
9) You will consider getting a better bicycle as you understand it better through your rides.
10) You may even feel competitive enough to join a cycling event.
11) Your group of cycling friends will expand.
12) You are likely to carry stuff and add more gizmo on your bicycle like bags, bike tools, a cycle computer or even a GoPro to record more interesting rides.
13) You become more particular about the handlebar, saddle, tyres and tubes you use on your bicycle.

These are actually the differences I noticed in my customers after they have been cycling for a period of time.
