Everybody here will likely disagree with me but I will say, for your intended purpose, Yes . . . for a while.

The caveats:

• Too much actual trail riding and things will begin to break.
• You will find it a bit heavy
• The "suspension" has no damping; so the springs will rebound uncontrolled, which will make for some spooky handling if you really begin to push it on trails.

But if you just need something to tool around on and get the feel of riding and a feel for what you want/don't want if you decide to get more involved, then why not?
