It just has been released a few weeks ago the new starting regulation for a new category of vehicles in Spain that are called VMP.
This one includes vehicles of 1+ wheels that move only with electric motor/s and can have a seat or not, and with a maximum speed up to 25Km/h on flat.
There is two kinds, personal transport (only for one person) or goods transport. Both with very interesting technical characteristics.
This opens in Spain a whole new world of vehicles that can be driven in the roads and bike lanes.
