grrr new bike rims/wheels

Are they getting side to side movment by the axle or is the rim bent??

Your bearing could be loose that's an easy fix. Or the rim could be out of true. I paid like $10 for the local shop to true my wheels.

Cheap Chinese prices are great, but cheap Chinese quality is what you get for your money. Even if your bike came with perfect wheels, they're not going to stay that way long on a motor bicycle, because they're light duty low cost wheels.

The best thing to do is junk your stock chinese light duty wheels, and buy a set of heavy duty wheels that can stand up to the demands of a 30+ mph motor bicycle. Expect to spend about $75 each wheel. Yeah that's more than your bike cost, there's no free lunch.

If that's not an option, take your wheels to a bike shop and have the rims trued, and the spokes tightened. That'll cost about $30 or $40 for 2 wheels. Normally it's only the rear wheel that goes off true very often. Once you get the front wheel trued it probably won't give you too much trouble. But truing the stock rear wheel is only a temporary fix. Depending how hard you ride it'll be out of true again in a few hundred miles.

After your rear wheel has been trued about 3 times expect spokes to start breaking. That will tell you when it's really time to buy a new wheel, if you're still riding a mb by then.

One thing I think you've got going for you is your wheels may be steel. That should last a little longer than the stock alloy wheels that came on my cheap bike.

My experience with buying big stuff online is they never want to take it back and pay for shipping again. I got half of my money refunded for a dented fender once. Try calling them ask for a partial refund say 50 percent and use that towards a new set of wheels. You should at least try.

I bought a set of 11g wheels with a front strumey archer drum for about $190 but the will never break with what I do with them. I had already broken some spokes on the 14g stock wheels.
