I wish they were more common in the States, but they are catching on slowly. I got mine from the website and have found the company easy to communicate with any questions. I would also recommend finding a good bicycle shop in your area, I take mine from in for an annual safety check where they check the nuts and bolts (literally) and tighten the break cable when needed. It isn't expensive and keeps the bike in top condition. All my best if you decide to give it a go!
