10 Best Cheapest Folding Bike 2025 in the United States

The Brompton C Line 12-Speed Folding Bike is a premium choice for city commuters and urban riders who want a compact, easy-to-carry bike without sacrificing performance. It folds quickly in about 20 seconds to a very small size, making it convenient to store under a desk or carry on public transport. Weighing 26.4 pounds, it's lightweight for a steel-frame bike but not the absolute lightest in the folding bike market. The 16-inch wheels are a typical size for Bromptons, balancing portability and ride comfort on city streets. Its Chromoly steel frame is hand-brazed, offering excellent durability and a smoother ride compared to aluminum frames, though it adds slightly to the weight.

The 12-speed gearing is a standout feature, providing flexibility for tackling hills and longer rides, which is more than many folding bikes offer, making it a versatile option. The folding mechanism is well-engineered and reliable, known for easy folding and unfolding, though this quality often comes with a higher price tag. The ride quality is smooth and stable on paved surfaces, reflecting Brompton’s reputation for urban-friendly bikes. However, this bike is on the more expensive side compared to other folding bikes marketed as 'cheapest,' so it suits those willing to invest in longevity and premium build rather than just the lowest cost.

Assembly is minimal—just attach the saddle—which is great for beginners. This bike also includes useful accessories like fenders, a bell, and a pump, adding value for daily commuting. In summary, the Brompton C Line 12-Speed is ideal for urban adults seeking a durable, highly portable bike with versatile gearing and excellent build quality, but it might not fit those strictly looking for the lowest-priced folding bike option.

The Brompton C Line 6 Speed Folding Bike is a well-crafted option for those who need a portable and efficient bike for urban commuting. One of its standout features is its compact folded size of 25.3 x 23 x 10.6 inches, making it easy to fit into small spaces like car trunks or public transport. Weighing in at around 26.7 pounds, it is relatively lightweight for a folding bike, comparable to a small suitcase, which adds to its portability.

The 16-inch wheels are suitable for city riding, providing a balance between ride comfort and compactness. The frame is made of alloy steel, known for its durability and sturdiness, which is crucial for a reliable ride. With 6 gears, this bike offers versatility to handle various urban terrains, making it suitable for both flat and mildly hilly areas. The mid handlebar design ensures an upright and comfortable riding position, reducing strain on the back and providing a good view of the road.

The Brompton's folding mechanism is expertly engineered, allowing the bike to transform into a small, locked package in under 20 seconds, which is a significant advantage for quick transitions. However, the rigid suspension might not provide the smoothest ride on rough roads, and the relatively small 16-inch wheels may not be ideal for longer distances or very uneven surfaces. Additionally, while the bike is robust and highly portable, it comes at a higher price point, which might be a consideration for budget-conscious buyers. If portability and compactness are top priorities, the Brompton C Line 6 Speed Folding Bike is a strong contender in the folding bike market.

The GELEISEN Folding Electric Bike is a solid choice if you want an affordable folding ebike with some cargo-carrying ability. Its 20-inch fat tires (3.0 width) offer good stability and comfort on city roads or light off-road surfaces. The aluminum frame keeps weight manageable at around 51 pounds, which is a bit heavier than some folding bikes but understandable given its motor and battery. It folds using a simple two-step mechanism, making it reasonably easy to store or carry, though it’s not the most compact when folded.

The 6-speed gearing combined with three riding modes (all-electric, pedal-assist, and regular bike) gives you flexibility to handle different terrains and control your effort. The 350W motor can reach speeds up to 20 mph with a battery range of about 15.5 miles on full electric mode, which is decent for short commutes but may require frequent charging for longer rides. The built-in cargo rack is a nice bonus for carrying groceries or gear up to 300 lbs total, making it practical beyond just casual riding. Ride quality is enhanced by front suspension and fat tires, which smooth out bumps well, while dual disc brakes add reliable stopping power.

The bike comes mostly assembled and includes useful extras like a horn, kickstand, and mudguards. Although it is somewhat heavy and the folded size isn’t the smallest for tight spaces, it balances price and features well. It is suitable if you want a durable, versatile electric folding bike with cargo capacity without spending too much.
