A new discount for electric bike rentals is now available through the Bonjour RATP app, which lets users find, unlock, and manage bikes from three companies—Lime, Dott, and Voi—all within a single app. This means users don’t need to download multiple apps or create separate accounts to use different bike rental services. The discount is valid until September 30, 2026, and is limited to the first 70 trips each day, with a maximum of one discount per person per day. In busy areas, these discounts may be used up quickly, especially in the late afternoon, so users should plan accordingly if they rely on the 4-euro discount for their trips. To use the discount, users should open the Bonjour RATP app and either search for a bike on the home map or use the route search feature to locate a Lime, Dott, or Voi bike. Once found, they can unlock the bike by scanning its QR code using the "Scan to unlock" button in the app. If the trip falls within the first 70 of the day, the 4-euro discount will be automatically applied at checkout. For short trips, the discount can significantly reduce the cost. Electric bikes are typically charged based on rental time, and some operators also charge an unlocking fee. According to the Bonjour RATP FAQ, a 20-minute rental would cost the following with the discount applied: - Dott: An initial 1 euro unlocking fee, plus 0.35 euros per minute, totaling 8 euros. With the discount, this would cost 4 euros. - Lime: A 1 euro unlocking fee, plus 0.28 euros per minute, starting at 6.60 euros. With the discount, it would start at 2.60 euros. - Voi: No unlocking fee, with a rate of 0.25 euros per minute, totaling 5 euros. After the discount, the cost would be just 1 euro. This discount could be especially useful for short, local trips, helping to make electric bike rentals more affordable for users in urban areas. However, due to the limited daily quota, the discount may not always be available, especially during peak hours.
