People, do you realize this post started in July and now it's near the end of September? Poor Caroline162, the OP if you might have forgotten, will need snow tires to go on her bike if she hasn't bought it by now.
Having gotten that off my shoulders I would like to agree with most everyone who hates to buy from Walmart. There is virtually nothing good they have done for this country since Sam passed away.
I personally hope Caroline162 did get a bike from some where, Walmart or not, and is enjoying it. She sounded like a very brave determined lady to post such a question in this forum to start with and I wish her well.
In case she is still following this thread, I would like to suggest that she have the pedals tightened by her neighbor biking friend if she hasn't done that already. I saw a young rider in a local charity ride this summer eat pavement when one of his Walmart half a** installed pedals broke off the crank arm. They use cheap 1/2" pedal threads and don't torque them properly so when they lossen up a bit they easily strip the threads.
