A side-by-side tandem bike (also called a couples bike or duo bike) is designed for two riders sitting next to each other, rather than one behind the other. Each rider has their own set of pedals and handlebars (the passenger’s may be fixed on some models). This type of bike encourages communication, inclusion, and shared effort, making rides more social and enjoyable. It’s commonly used for leisure rides, adaptive cycling, and recreational outings where comfort and stability are key.
