Mopeds are currently not available in the UK.
The price of your moped trip will consist of a fixed activation fee (unlocking) + the value per minute of rental.
In addition, while you are in pause mode ('Park'/'Parking'), a reduced rate will be charged. The total charge will be made at the end of your journey.
Check the exact prices for your city from your App, by selecting one of the available mopeds and breaking down the details of the rate.
