Help me with my bike prob

I have two set of wheels in my new bike, I don't want to use the original wheel set so I switched out to another one. I'm pretty sure that the wheel is not a fixed hub. After putting the cassette from the original set of wheels to the other, when pedals backward, the cassette seems to move into the direction of pedal. Is it possible that I did something wrong, or can it be that the second rear wheel has a fixed hub that allows me to add on gears? I thought fixed hub doesn't have any gears on em...

When you peddle backwards does the bike go backwards? What happens when you stop pedaling?

Maybe the second wheel has a jammed ratchet barrel?

It's the splined sleeve you inserted your cassette into. It's got pawls inside to allow your rear wheel to freewheel.

Take the cassette off and you should be able to rotate this barrel freely counterclockwise without the wheel moving. If it doesn't might pay to take it to your LBS.

If it does, but when you reinstall the cassette then it won't, check if there's something rubbing in between the largest cog of the cassette and the spoke flange of the hub.

Without seeing anything... this is all maybe...

cheers
