Folding Bikes

A folding bike is a bike that incorporates collapsing parts—typically including top tube, pedals, and handlebars—so it can be folded and stored without taking up much space. You can stash folding bikes in your car trunk, closet, or even under your bed. If storage and portability are your main concern, folding bikes can’t be beat! (In addition to traditional folding bikes, there are also folding ebikes, which offer the added benefit of electric motors!)

Folding bikes offer easy storage and portability, ideal for urban dwellers with limited space or commuters who mix transportation modes. Their compact folded size lets you carry them with you on public transport or store them in offices, apartments, college dorms, and other places where space comes at a premium. This also enhances security, as folding bikes can be kept indoors at night, reducing risk of theft.

Folding bikes prioritize a compact size, low weight, and portability over performance and comfort, so they do have a few drawbacks. The smaller wheels and shorter wheelbase are less efficient than those on a full-sized bicycle, and can feel less stable and comfortable, particularly when riding fast or on bumpy terrain.

It varies based on the bike, but in general, folding bikes are lighter than normal bikes. Our Judd Folding Bike weighs just 24 lbs!

While some folding bikes are more expensive than traditional bicycles, here at retrospec, our folding bike costs just $329, which is a comparable price point to our full-sized bicycles.

It varies based on the bike. Our Judd Folding Bike collapses to an ultra-compact 32” x 30” x 10”.

It’s very simple to fold and unfold a folding bike. There are three main collapsing points: the top tube folds in half, the handlebars fold down to nest parallel to the bike, and the pedals fold upwards for a compact, lightweight package. This process can be accomplished in a couple of minutes.

No, folding bikes don't break easily. Our folding bikes are designed with robust aluminum frames and simple, single-speed drivetrains, with reinforced folding mechanisms to minimize wear. Like any bike, a folding bike will require proper care and maintenance, but you won’t see reduced durability compared to a normal bicycle.

No, folding bikes aren't inherently harder to ride than normal bikes. They might feel slightly different due to their smaller wheels and compact frames, but most people adapt quickly. The key is to adjust the seat and handlebars for maximum comfort and control.

Yes, folding bikes can be a good choice for beginners because they are accessible, simple, versatile, and adjustable. They are also portable and compact, making them a good option for commuting or leisure. That said, for complete beginners, it’s perhaps best to learn on a full-sized bike. The wheel size and frame on a folding bike are much smaller, and riding a folding bike—while not hard—feels slightly different than a normal bicycle.

A folding bike can certainly handle long rides, but these bikes are built for portability, not comfort and performance. Their smaller, lower frames and wheels mean they won’t be as comfy as models purpose-built for long rides, like city bikes and road bikes. Folding bikes are best used for shorter ventures or urban commutes with mixed transit modes. (For example, if you’re combining cycling with buses, trains, and/or metros.)

Yes! Judd has a 30.4 x 600mm aluminum seat post with a micro-adjustable head, allowing you to fine-tune the height to suit your build. That said, with any retrospec bike, always check the “Sizing” tab on the product page for more information. Judd, for example, is optimized for rider heights from 5’2” to 5’10”.

Folding bikes are designed for easy carrying. Once folded and locked in place, you can lift them by the frame or handlebars. The Judd Folding Bike weighs just 24 lbs, so it’s not hard to carry with you on the subway or bus, or into the elevator at work, for example.

Locking a folding bike is essentially the same as locking a regular bike. You'll want to use a high-quality bike lock—ideally a U-lock or chain lock—to secure the frame and at least one wheel to a solid, immovable object like a bike rack or sturdy pole. If your folding bike has quick-release wheels or a seat, it's wise to secure those components with additional locks or skewers. For enhanced security, you might consider using two locks of differing types. Finally, park your bike in a well-lit and visible area whenever possible.

Folding bikes are designed for portability, not speed and performance. So yes, all things being equal, you’ll probably be able to ride faster on a road bike, city bike, hybrid, or other traditional bicycle than on a folding bike.

If you’re looking for a folding bike that can reach high speeds, consider folding ebikes! Our multi-surface fat tire Jax Rev and our classic lightweight Judd Rev can both hit a 20 mph top speed, with multiple levels of convenient pedal assist and a thumb-operated “push-to-go” throttle. If convenience and portability are your top priorities, a folding ebike will hit the mark and offer the added boost of an electric motor.

Folding bikes aren’t built for speed. They have a single gear and smaller wheels than a traditional bicycle. However, as with any bike, the answer depends on how fast you can pedal (or how steep the hill is).

Of course! Because their wheels are smaller than normal bicycles, folding bikes essentially have lower effective gearing than normal bikes, so it’s easy to pedal uphill.

Normal folding bikes are best suited for smooth surfaces, like asphalt and concrete. That said,retrospec does offer an off-road-capable folding ebike, Jax Rev. This rugged little bike sports fat 20” x 3” tires with deep-set lugs to dig into loose terrain. It can reach speeds of 20 mph, and travel up to 46 miles on a single charge! If you’re really looking for an off-road bike, don’t miss our mountain and gravel bikes and fat tire ebikes.

All bikes have a weight limit. This varies depending on the model, but in general you can expect a slightly lower limit for a folding bike compared to a normal bicycle. The maximum recommended weight for our Judd Folding Bike is 250 lbs.

Because folding bikes are focused on compact size and portability, they’re usually single speed, meaning they have one fixed gear. This minimizes weight, bulk, and price, and also results in reduced maintenance.

It depends on the airline, but usually yes! If your bike fits in a suitcase that meets the airline's size and weight restrictions, you can always check it as luggage. You could also bring your folding bike as a carry-on, but you may need to remove the seat and loosen the handlebar clamp to get it down to size.

Yes, depending on the carrier. On Amtrak trains, for example, bikes are allowed both in checked baggage and on trains with walk-on bicycle service. Folding bikes under the dimensions of 34” x 15” x 48” (like our Judd Folding Bike) are also permitted as carry-on luggage.

If portability and storage are your top priorities, retrospec makes it easy to choose. The folding bike collection comes down to two standout options, each built around the same core idea: a bike that fits into your life without taking over it. The Judd Single Speed Folding Bike is the go-to pick for riders who want simplicity and portability at an accessible price. It weighs just 24 lbs, folds down to a compact 32" x 30" x 10" in seconds, and features a lightweight aluminum frame, a no-fuss coaster brake, and grooved commuter tires that handle city streets confidently. At $369.99, it's one of the best-value folding bikes available, and it fits under your desk, in your car trunk, or in a closet without taking up any real space.

For riders who want to go further and faster without carrying a heavier bike, the Judd Rev 2 Folding Electric Bike is a compact powerhouse. It pairs a foldable aluminum step-through frame with a 350W motor, a 36V/360Wh removable battery, throttle and pedal assist, up to 42 miles of range per charge, and a built-in headlight and taillight, all folding down to 34" x 28" x 20" for easy storage and transport. At 42 lbs, it's significantly lighter than most folding electric bikes, which makes it genuinely easy to carry up stairs, onto a train, or into a building. Both are UL 2849 certified for electrical safety (Judd Rev 2) and ship free.
