Is a Shimano TZ-37 Megarange gear set a Cassette or Freewheel?

I can probably tell the answer if I take it apart, but I am hoping someone will have a quick answer. It really should be a cassette because this is a brand new bike, but you never know what old parts are left over. Thanks guys.

Freewheels are alive and well at the bottom end of the market. Most department store bikes still use freewheels.

I've got a page with photos dedicated to determining which system your bike has:

Thanks, I am familiar with how to tell them apart but I was hoping to avoid any disassembly, as I have to order parts today and I am not near the bike. I understand about low end bikes, I just never considered Fuji low end.

I did a quick google search, from all indications it's a freewheel-

I think the simple test is to spin the cog on the wheel and see if the splines spin with the cogs. If they do, then it is a cassette, if they don't move, it is a freewheel.

You don't need to take anything apart.

You never mentioned what kind of bike you were dealing with in your previous message. Fuji is a full-line manufacturer, with low-, mid- and high-level models.

Thanks guys, you were right, it is a freewheel. I was able to get a few replacement Shimano freewheels for about $8 each so I probably won't run out of parts when I need replacements so I appreciate the help. Slowly I am getting the hang of this but I still cannot tell what I am looking at. A few more parts in my hands and I will not be quite so ignorant.
