For people who want to be daring or do some dangerous stunts, a Standbike would be all you need. At the moment the Standbike isn’t quite available to the public but if you want to try experimenting on one, it is really a Vespa without the seats, in a manner of speaking.

Powered by a 250 ccm Aprilia engine, the Standbike has a top speed of about 87 mph and it provides a unique riding experience since without a seat you need to use your whole body to brace and balance during acceleration, braking and cornering. Not surprisingly the Standbike isn’t street legal and is designed to be enjoyed on a closed track with plenty of safety gear, but there is a seat accessory that can be easily attached allowing it be used like a regular scooter on public roads.
