I would like to buy a new treadmill,but have no idea what is a good brand and what specifics I have to watch out for.

It should cost under 20000THb,should have a bandwith of minimum 50cm/20inch,length of 140cm/56inch and it should be

foldable.I'm not a pro runner just want to work out sometimes.So which brand is good,where to buy,how many horsepower do I need?

Any suggestion will help,thanks

You also need to make sure it can handle your weight. Some exercise machines have a max weight of 80 kg for instance.

With a 20k budget, you should be able to get a strong, sturdy machine, though.

You should look at decathlon (webshop or a shop near you) At least its offered at a competitive price and it is better at warrantee then many other companies. 

 

Personally if you want a full proof machine (but more expensive) buy a concept 2 rowing maching. It will last you a lifetime. Though i admit it takes more effort then a treadmill. But no repairs ever and really small if you put it away. 

 

But if you want a treadmill, do look at decathlon at least with warrantee in your mind.
