Folding Bicycles for Sale on the Internet

The folding bike market is normally broken into segments by wheel size. We will examine each segment listing the positive features ( pro ) and negative features ( con ) of each.

A. Full Size Wheel Folding Bikes:
The main brands in this segment are Dahon and Montague. The Dahon Jack is one of the most popular choices due to its low cost and excellent component package.

Pro:   

1. They feel like a normal bike, mainly because they are a normal bike that happens to fold in half.
2. They are smaller than a standard bike so they are more portable.
3. They are relatively cost effective compared to some small wheel models.
4. They use standard parts so they are easy to upgrade or fix.

Con:

1. Although they are smaller than standard bikes, they are still big and bulky.
2. You need to select the proper frame size to fit your body. Hence purchasing online may not be a good option.
3. They are heavier than standard bikes due to their folding nature.
4. B. 20" Wheel Folding Bike:
5. The main brands are Dahon and Downtube. The best cost effective choice is probably the Downtube Nova at $299, while the Downtube 9FS with 9 speeds and full suspension is the best bang for your buck.

Pro:

1. They are small enough to pack for airplane,  boat , or RV use.
2. Prices are reasonable with a wide range of possibilities.
3. Lighter than normal bikes because they are smaller.
4. Smaller wheels are more efficient than bigger wheels under 16mph.  Hence this bike is faster on hills and flats.

Con:

1. Many low quality folders with 20" wheels can confuse buyers.
2. They are slower decending downhill.
3. Some models may need a little disassembly to place in regulation size luggage.
4. Some models use proprietary parts.

C. 16" and 18" Wheel Folding Bikes:

The main brands are Brompton and Downtube. The Brompton is a great choice; however at a $1200 price we feel the Downtube mini is better. It is lighter than the Brompton and has a better component package (and it costs less than half as much).

Pro

1. Most are super compact and can fit in regulation sized suitcases without disassembly. Some even fit in overhead bins on airplanes.
2. They are very light due to small size.
3. They are cool looking and you are guaranteed to make plenty of friends riding one.
4. These are little rockets on hills and flats due to higher efficiency of the smaller wheel.

Con:

1. These cost much more than 20" wheel folding bikes.
2. Parts are harder to replace because the size is not standard.
3. Proper gearing is very difficult to configure on small wheels.
4. Less possibility for upgrades due to lack of parts. Especially relevant is the lack of 16" wheel suspension forks.
5. The ride is stiffer than big wheel bikes due to smaller frames which absorb less shock and small wheels also absorb less shock. Hence the rider absorbs more of the road shock. Overall we have to say the Downtube 9FS full size folding bikes is a great choice. It’s comfortable, folds compactly, has a racing quality drive train and costs only $550.
