The Sunny SF-B223011 is a classic folding X-bike: an upright seat, a scissor-style frame that closes up, and wheels to roll it into a cupboard. It does not try to be a recumbent or a multi-gym. Its appeal is a clean, simple design with more resistance levels than many folding bikes and a free app, which suits flats and shared rooms.

Our take
Frame and folding
The compact X-frame folds in seconds, according to Sunny, and transport wheels make it easy to move once folded. Set up, the listing gives dimensions of 85 by 55 by 134 cm and a weight of 20 kg. The steel frame is rated for 135 kg (300 lb) and carries CE and EN certification, per the listing. Sunny also mentions a rust-resistant finish.
Ride and resistance
There are 14 magnetic levels with a sealed belt drive. Sunny says the sealed magnets and belt need little maintenance and run quietly enough not to disturb others. The riding position is upright, with an extra-wide padded seat in soft high-density foam and non-slip pedals with adjustable straps.
Display and app
The LCD shows time, speed, distance, calories, total kilometres, RPM and pulse rate. Pulse comes from sensors in the grips, so you do not need a chest strap. Over Bluetooth, the bike pairs with the SunnyFit app, which Sunny says is free with no membership fee and includes over 1,000 workouts and over 10,000 virtual routes. Holders for a phone or tablet and for a drinks bottle are part of the frame, so you can stream a class and stay hydrated without extra accessories.
Choosing between the Sunny folding bikes
Sunny also sells the SF-B223012, which adds a mesh backrest and arm bands to a similar folding frame. That version suits riders who want back support, while the SF-B223011 stays lighter and simpler. If you want several riding modes including a recumbent position, the YOSUDA 5-in-1 is the multi-mode alternative.
Who should skip it
The listing gives no rider height range, so very short or very tall riders should check the seat adjustment in the photos or manual. Anyone wanting to recline or work the arms will be better served by a convertible model.
Verdict
The Sunny SF-B223011 is a sensible buy for anyone who wants a simple upright bike that folds away, with a useful spread of levels and a free app. Riders who want back support should look at the Sunny SF-B223012, and those wanting recumbent and arm modes should consider the YOSUDA 5-in-1.
