26" Folding Mountain Bike & 24 Inch 21 Speed, Double Suspension Alloy Wheel

This folding mountain bike from Selling United combines compact portability with genuine off-road capability, making it a practical choice for commuters who want one bike that works across commuting, leisure rides, and rougher terrain. Available in both 24-inch and 26-inch wheel sizes, it folds down for easy transport and storage in small spaces, which matters if you're mixing cycling with public transport or need to keep it in a flat or office.

The frame is built from aluminium and steel alloy, keeping weight down whilst maintaining rigidity, and the full suspension system—front and rear—soaks up bumps and roots when you venture off tarmac. This translates to a more comfortable ride on uneven ground, though it does add a bit of weight compared to rigid alternatives. The 21-speed derailleur gears give you a decent range for climbing hills and cruising flat sections, and the mechanical disc brakes are responsive and reliable in wet conditions, which matters for year-round British riding.

Day to day, the all-terrain tyres work across road, trail, and rougher ground without needing tyre changes. The black frame with red detailing is straightforward and unfussy. Assembly is partial—the bike arrives mostly built, though you'll need to fit the handlebars, pedals, and front wheel yourself, which most cyclists find straightforward with basic tools.

This folding bike suits riders who want versatility without paying for a full-suspension road bike or commuter-specific model. If you're juggling short urban commutes with weekend rides on bridleways or gravel, or if you need a bike that folds away but still handles genuinely rough terrain, it covers the basics well. The 26-inch version offers better rolling momentum and slightly smoother riding, whilst the 24-inch folds more compactly and suits tighter storage or easier portability on trains and buses.
