wow, $150 with shipping, thats not bad at all! is this bike durable, is it going to last a while or star braking down after a few months of use? she says she wants bigger wheels because 20" seem a little too small. as far as carrying it around, we will only be taking it down the stairs and up the stairs in our apt building, other than that, no other carrying. and yea, 37lbs is veeeeeeeeeery heavy, didn't even see it.
