16" Girls Mongoose Pizazz Problem!!!

We purchased a Mongoose Pizazz 16" bicycle for our 5 year old daughter's birthday. While checking the bike after assembly we noticed that the back wheel does not spin unless the pedals are moving. Any ideas on what the problem might be?

Some bikes are like that. The rear wheel only spins with the pedals. Try pedaling backwards and see if the wheel goes back. If it does then that is normal.

My 5 year olds 16"

YOU need to assess if something is rubbing somewhere or the bearings are shot. Remounting the wheel correctly will solve the rubbing issue and probably eliminate a dangerous condition.

If the latterer, decide if repair or replacement is the better avenue. A bicycle shop could repair/relube the bearings faster and cheaper than locating a matching wheel.

I am trying to put on the front wheel but it is not fitting, there is a washer tightened on each side towards the wheel. Am I supposed to take those off before trying to put the wheel on? Otherwise, what...

If you're talking about the washers which can screw in and out you don't take them off. They hold the ball-bearings, that the axle turns on, in place. If you have moved them you should adjust them so that when you hold the wheel by the axle at each side the weight of the valve, for pumping the wheel, moves to the bottom i.e. next the ground. Any tighter is too tight any looser is too loose. You need to pull he forks of the bike frame slightly apart to get the wheel to fit between them.

If you're talking about washers that can pull off rather than screw off they can be taken off and put on the axle outside the forks next the nuts which hold the wheel on.

What causes my mongoose freestyle girls 20" hard to pedel?

Could have sticky or seized up crank bearings where the pedals are or the rear wheel bearings. Have you tried pedaling and spraying a lubricant where all the bearings are or remove and re-grease the bearings?

Where can I find a replacement seat for my daughter's 16" princess bike

Hello. Any Walmart or bike shop will have replacement seats. All bike seats are interchangeable. If you take the bike to a bike shop they will probably install the new seat for you. Otherwise you will need a crescent wrench ot set of socket wrenches to do the job. Regards, Joe

Where can I find a replacement seat?

A good bicycle dealer?repair shop should be able to help you. Take the seatpost and old seat if you have it with you and they can sell you one. They will definitely need the seatpost to match the seat.

Childs 12 inch mongoose is new, but back wheel does not spin prop

The bikes are pre-assembled by a machine that overtightens the rear axle.  I had the same problem with my daugher's 12 inch huffy princess bike and my other duaghter's 16 inch Schwinn bike.  If you loosen the nuts on the back axle it fixes the problem.  I have read that the idea thing for these bike is to have them re-assembled and re-lubricated by a bike shop, but I thought this might cost as much as I paid for the bike.
