In a word: NO!

First off, what do you want to do with it?

If you are going to ride on paved roads or fairly smooth dirt/gravel
trails, you don't need dual suspension (or any suspension). The
suspension on a bike in this price range is very heavy and prone to
early failure. Consider a hybrid bike at a local bike shop.

If you want to do serious off road riding, this bike will not last
long.

The bike you mention almost certainly comes as "one size fits all" and
is poorly assembled at sport mart.
