SEVIci User Guidelines
Welcome to SEVIci, Seville’s public bicycle-sharing service. This system is designed to provide residents and visitors with an eco-friendly, efficient, and healthy alternative for short-distance urban travel. To ensure a safe and harmonious experience for all users and pedestrians, please adhere strictly to the following regulations:
* Registration and Access: Users must be at least 16 years of age to register. Minor users (ages 16–17) require authorization signed by a parent or legal guardian. Subscriptions can be purchased online or at designated system terminals using a credit card.
* Usage Limits: Bicycles are intended for short trips. The first 30 minutes of each journey are free. Trips exceeding this duration will incur additional charges billed to the registered card. Bicycles must not be kept for more than two consecutive hours; failure to return the bicycle to a docking station within this timeframe may result in account suspension and a penalty fee.
* Safety Rules: Helmets are highly recommended for all users and are legally mandatory for those under 18. Bicycles must be ridden on designated bike lanes (*vías ciclistas*) where available. Riding on sidewalks is strictly prohibited unless specifically marked. Users must respect all traffic signals and yield to pedestrians at all times.
* Return Protocol: When returning a bicycle, ensure it is securely locked into the docking station. A green light and an audible beep confirm a successful return. If the station is full, press the screen at the terminal to receive 15 minutes of free additional time to locate the nearest available station.
