RadExpand 5 is the budget-friendly contender that brings practical performance and commuter-ready features to the small-wheel folding segment, offering one of the most aggressive price-to-spec ratios on the list. While it doesn't match Brompton's compact fold or GoCycle's lightweight engineering, it excels as an affordable, serviceable platform with wide U.S. support and a sturdy ride for everyday use.

The Dahon Mariner D8 is a market-leading, value-focused folding bike designed for salt-air commuting and travel, featuring rust-resistant hardware, an 8-speed drivetrain and a reliable fold for frequent transport. It undercuts Brompton on price while offering more gears and corrosion protection, making it an attractive technical and financial choice for budget-conscious urban riders and boat/harbor commuters. Against the Tern Link D8 and Dahon Speed D7 it emphasizes durability in corrosive environments and practical gearing without the premium compactness of a Brompton.

Montague Paratrooper Express
The Montague Paratrooper Express is unique in this list as a full-size folding aluminum bike designed for rugged performance rather than ultra-compact stowage, offering higher speed, stability, and off-road capability than small-wheel folders. While it is heavier and bulkier folded than the other entries, it provides technical advantages for riders who need full-wheel dynamics and durability—trading compactness for performance that small-wheel bikes like Brompton or Tern cannot match. Financially, it appeals to buyers who want a single bike for both folding transport and serious off-road or fast-road riding, avoiding the need for separate bikes.

The Montague Boston 8 is an outlier on this small-wheel list—being a full-size-wheel folding bike that provides a bicycle-like ride, larger 700c wheels and a broader gear range which favor longer-distance comfort and rolling efficiency. Although it doesn't compete on folded compactness like Brompton or BYB, it offers superior road performance and excellent value for riders willing to trade a smaller folded size for speed and stability.

The Paratrooper Pro is an outlier in this list — a full-size-wheel, foldable suspension bike built for heavy-duty, off-road and tactical use rather than micro-compact urban storage. Compared with the small-wheel entries it offers far superior ride stability, suspension travel and load capability at the expense of compactness and lighter weight, making it the practical choice when off-road performance or rugged durability outweighs the need for the smallest possible folded footprint.
