I purchased the half-bike when I broke my coccyx. It took a few days to master; it may be a 'half bike', but it is not bike-like. It takes time to learn to balance and steer. The process was much easier once I realised that the back wheels steer. Be prepared; it is a workout and a lot of fun. It would be best to have flat roads/paths, though, as I struggled with hills. And you'll get noticed! The best part, though, was taking it on holiday. I dismantled the half-bike, packed it into the car and drove to the south of France.
