The VRAi Fitness SXB-350 Folding Exercise Bike is one of the most versatile and interactive foldable bikes on the market. Built with magnetic resistance technology, it delivers a smooth, whisper-quiet ride that won’t disturb others—perfect for home gyms, flats, or late-night workouts.
With 10 adjustable resistance levels, you can tailor your training from gentle cardio to muscle toning. The bike also supports 3-in-1 workout modes: upright for intense sessions, semi-recumbent for low-impact training, and recumbent for longer, comfortable rides. This flexibility makes it suitable for all ages and fitness levels.
The Bluetooth console is compatible with the Kinomap app, giving you access to real-world cycling routes, virtual competitions, and live streaming classes. The LCD display tracks time, speed, distance, calories, and pulse, while the built-in heart-rate sensors on the handlebars help you stay within your training zone. A large iPad/phone holder with anti-skid silicone keeps your device secure for interactive or entertainment use.
Built with a reinforced steel frame and extended stabilisers, the SXB-350 supports up to 150kg (23.6 stone). The ergonomic design includes an adjustable padded seat, backrest, and height settings, making it comfortable for users from 150cm (4’11”) to 191cm (6’3”).
For convenience, it folds in seconds to just 27.5 x 140cm, small enough to store under a bed. With transport wheels, you can easily move it between rooms. Backed by a 12-month warranty and customer support, it’s a reliable, space-saving choice for home fitness.
