10 Best Lightest Folding Bike 2025 in the United States

The Cybervelo 1000W Folding Electric Bike is a strong contender in the folding bike category, especially for those looking for an electric option. One of its standout features is the powerful 1000W motor, which offers a peak of 1500W, making it suitable for tackling steep hills and long distances. This power, combined with a 7-speed transmission, ensures a smooth and versatile riding experience. The large 48V 20.8AH removable battery provides an impressive range of up to 80 miles, making it ideal for extended commutes or adventurous rides.

The bike's 20-inch fat tires are designed to handle various terrains, including snow, beaches, and rugged mountain roads, while its dual suspension system and high-strength shock-absorbing front fork enhance comfort on rough paths. Safety features include dual disc brakes and EABS power-off brakes, ensuring reliable stopping power. One of the main advantages of this bike is its foldable design, making it easy to store and transport. The smart LCD display with a charging port adds convenience by displaying real-time speed, mileage, and battery status.

It's worth noting that the bike is made from high carbon steel, which, while durable, may add to its weight compared to lighter materials like aluminum. The assembly required might be a slight drawback for some users, although the bike comes 90% pre-assembled. Additionally, with a weight capacity of 330 pounds, it accommodates a wide range of riders. The bike also includes features like mudguards, an adjustable seat, and dual suspension for added comfort. Those specifically looking for the lightest folding bike might find it heavier due to its robust build and fat tires. This bike is best suited for adults seeking a powerful, versatile, and comfortable electric folding bike for various terrains and longer rides.

The YorkE Folding Electric Bike offers a sturdy yet foldable solution for riders looking for a versatile electric bike that's easy to transport. It features a carbon steel frame, which provides strength and durability but tends to be heavier than aluminum alternatives, so it may not be the absolute lightest folding bike available. The 20-inch fat tires enhance comfort and grip across various terrains, including roads, snow, and beaches, making it suitable for both urban commuting and light off-road adventures.

The folding mechanism is practical, allowing you to fold and carry the bike or fit it into a car trunk. With 7 gears and a powerful 750W motor (1000W peak), the bike easily handles hills and can reach speeds up to 30 mph, which is impressive for a folding e-bike. The large 48V 20.8AH removable battery extends your range up to 80 miles in pedal assist mode, reducing charging frequency and supporting longer rides.

Comfort is addressed through front suspension forks and shock-absorbing seatposts, plus reliable disc brakes with EABS for safe stopping. The bike comes 90% assembled, with some assembly still required. This bike represents a strong choice for those seeking a durable, powerful folding e-bike with good range and comfort, though if ultra-lightweight or compact folding size is a top priority, it may be worth comparing other models with lighter frame materials.

The Brompton C Line 12-Speed is a standout option for anyone looking for a lightweight, compact folding bike built for city commuting and beyond. Weighing just 26.4 pounds, it’s relatively easy to carry and fits well under desks, in car trunks, or on public transport, which is key for urban riders. The bike folds up quickly in about 20 seconds, making it highly convenient for those who need to switch between cycling and other travel modes. Brompton’s folding mechanism is known for its clever design, and this model continues that tradition, allowing it to be rolled like a small suitcase when folded, especially if you add the optional roller rack.

The frame is made of hand-brazed Chromoly steel, which offers a strong and durable structure while keeping the weight manageable. The 16-inch wheels strike a good balance between compactness and ride quality, and the 12-speed gearing provides a wide range to handle city hills and longer rides comfortably. This makes it versatile whether your route is flat or has some elevation. Comfort features include three handlebar height options so you can choose what fits your riding style best, plus included accessories like fenders and a bell add practical value for everyday use. It comes fully assembled except for attaching the saddle, easing the start for beginners. The bike is rigid with no suspension, which is typical for this class but means less shock absorption on rough roads.

A minor downside could be the price, as Brompton bikes are premium products with a reputation for quality and longevity, which is backed by a 7-year frame warranty. The folding size is compact but Brompton’s unique fold is a bit different from other brands, so it may take a little getting used to. Also, the 16-inch wheels aren’t as smooth over very rough terrain compared to larger wheels. This makes the Brompton C Line 12-Speed an ideal choice for urban commuters or anyone needing a reliable, quick-folding bike that's easy to transport and store. Its lightweight steel frame, versatile gearing, and thoughtful design make it a practical choice, especially if you value craftsmanship and long-term durability.
