Is 32km possible to ride with my body condition? My work place is 16km away from my home and the route I am traveling has traffic round the clock. 

I am planning to get a Kross K- 40 26T Multi Speed Bicycle to travel but I weigh 80kg and I am not fit (have both high and low blood pressure). My friend is scaring me that with this weight and health condition I can't ride 32km per day.
32km per day is a lot for some one who is out of shape.

I added the [commuter] tag to your post. If you click on it, you'll see hundreds of posts about commuting. Some are like this one, so your question may get closed if it's a duplicate.

Since you know you have health issues, the conservative advice is to discuss your plan with your doctor.

If it's medically ok to go ahead, then start by riding to work one day, then ride home the next day, twice per week. You will need to store your bike somewhere. Gradually build up, until you can ride both ways every day.

So, I agree with your friend, but you can build up to it.

Here is a similar (but not really duplicate) question: First time commuter needs advice. A couple of different answers will be helpful.
