Mongoose wheels...

Hi, I'm trying to switch the mag wheels on my son's Mongoose (probably about 8 years old) to spoke wheels. The tires on his wheels now say 20 x 1.95. Since I'll probably just keep the tires, what size spoke wheel should I be looking for? And is there anything else I have to consider when looking for new wheels. Thanks.

You want wheels with a 20” (451 mm) diameter.
And you probably want to check the type of hub.
BMXes can have both freewheel and cassette hubs.
Cassette hubs use a smaller rear sprocket and may not work that well with a BMX set up for a freewheel hub.
Wheels may be sold w/o sprocket/freewheel, so you might need to buy the right tool to transfer yours.

20x1.5 or 20x1.75 wheels would fit the bill. Watch craigslist for a suitable donor bike.

Thanks for your help. I'm not sure what type of hub it has, it looks like 1 "gear" on the rear wheel/hub.

”Cassette” for BMX doesn’t mean the same as it does for multi-gear bikes.
BMXes traditionally used freewheels, where sprocket and the ratchet mechanism that allows for freewheeling were treated as one unit.
Nowadays there”s ALSO the ”cassette” design where the sprocket is a SEPARATE part, held on by a lockring.
You need to figure out which one you’ve got.

Well,...a local bike shop (LBS) will usually teach you about bikes if you ask. This way you get to see, and be hands on.
