Boris Bikes is the nickname for the public bicycle rental scheme in London, officially known as Santander Cycles. Launched in 2010, the program allows users to rent bikes from various docking stations across the city for short trips. The bikes are designed for easy use, featuring a sturdy frame and a step-through design. Users can access the bikes by purchasing a day pass or an annual membership. The scheme promotes cycling as a sustainable mode of transport, helping to reduce traffic congestion and improve air quality in London. The bikes are easily recognizable, painted in a bright blue color with the London logo.
