10 Best 20 Inch Folding Bikes 2025 in the United States

The ZiZZO Campo 20-inch Folding Bike stands out for its portability, making it an excellent choice for commuters or those with limited storage space. Weighing about 28 pounds, it is relatively light, and its folded dimensions (H-27" L-31" W-12.5") ensure it can fit into small spaces with ease. The aluminum alloy stem and high-carbon steel frame offer a solid build, although the rigid suspension might not be ideal for rough terrains, making it best suited for road use. With 7 speeds and a twist grip shifter, it provides adequate gearing for various riding conditions, though it may not satisfy those seeking more advanced gear options.

The linear pull brakes offer reliable stopping power, but they might require more frequent adjustments compared to disc brakes. The bike is designed with user comfort in mind, featuring a wider saddle and adjustable seatpost and handlebar heights. The magnetic frame catch is a handy feature that keeps the bike securely folded. One potential drawback is the weight; at 31 pounds, it’s on the heavier side for a folding bike, which could be a concern for some users. Additionally, while it’s marketed as lightweight, it might not meet the expectations of those looking for ultra-light options.

Nevertheless, its ease of folding and the inclusion of folding pedals add to its convenience. Recommended for riders aged 16 to 75 and suitable for those with a height of at least 4.8 feet, this bike accommodates a broad range of users. To summarize, the ZiZZO Campo offers a good blend of convenience, durability, and user-friendly features, making it a strong contender in the folding bike category.

The Schwinn Loop Adult Folding Bike offers a practical solution for city commuting with its compact and lightweight design. Weighing 34 pounds, this bike is manageable for most adults and can fit riders ranging from 4'8" to 6'2". It folds neatly into a heavy-gauge nylon bag for convenient storage and transportation, making it ideal for those with limited storage space or who need to carry their bike on public transportation.

The bike's aluminum frame ensures durability while keeping it light, and the 20-inch alloy wheels provide a smooth ride on city streets. The 7-speed twist shifter allows for easy gear changes, helping you tackle different terrains with ease. Both the front and rear linear pull brakes offer reliable stopping power, essential for urban riding.

However, the rigid suspension may not offer as much comfort on rougher roads, and some users might find the bike a bit heavy compared to other folding models. Additionally, while the rear cargo rack is handy for carrying bags, it adds to the weight. It's important to consider your specific needs and whether the bike's weight and suspension type align with your preferences.

The bike is handmade in London and designed to fit most adults comfortably, with a natural, upright riding position and a versatile fit range from 1.4 to 1.9 meters in height. However, the smaller 16-inch wheels might not be ideal for rough terrain or long-distance touring. The rigid suspension may also mean a bumpier ride compared to bikes with built-in suspension.

Despite these minor drawbacks, the bike's ease of folding, compact size, and reliable components make it a practical choice for urban cyclists. Its glossy white finish and included components like a bell, reflectors, and Schwalbe Kojak tires add to its urban appeal.
