I think the folding wald baskets are great!!!

I installed a pair on my daughter's bike. You are correct that they are a little heavy but I don't think my 13 year old notices the weight. That is mainly because she rides a Schwinn Continental II ladies bike. She has to watch the local road weight limits (that is one heavy bike...but it is absolutely bomb proof).

She used it for riding back and forth to summer camp here in NW Indiana hauling both her and her little sisters gear. It worked great.
