To rent one of Madrid's publicly available electric bikes as a usario ocasional from one of the stations, choose a free card covering a one-, three- or five-day period. To secure the card, you pay a €150 deposit with a credit card – this amount is then adjusted according to how much you've used the bikes at the expiration of your card.
There are more than 1500 bikes available from 120 stations around the capital. While the system of annual subscriptions (abonos; €15 to €25) will most likely appeal only to residents, it is also possible to rent for one or two hours. Rentals are for a maximum of two hours at a time, with penalties charged (€4 per hour) for any time you use the bikes beyond that.
