If you were interested, postage prices from tartybikes to US for a bike is around £90-£120 depending on the size of the box. As was mentioned, I would recommend a 20" to either a young/shorter person or to someone who is from a bmx background and a 26" bike to adults and people used to MTBs. If you are just looking into a cheap bike, something from the onza 26" range is a good option. I actually quite like the Spyrogira, its a nice frame, simple (but good) brakes, no mechs and dirt cheap at £300
