One of the most common questions I get asked is how much more effort is needed to cycle on a folding bike compared to a touring bike. This is not surprising. At first sight my Brompton folding bike loaded with luggage at the back and at the front might look like a harder setup to ride.
My usual answer is: “It is just a little harder."
It is a rather vague reply but it is my experience over the years. I have extensively toured with mountain bikes and touring bikes in the past. On a folding bike you trade-off a little bit of comfort but in most situations, you will hardly be able to tell the difference.
A more interesting question to ask would be:
“Is the ability to tour and explore places limited by using a folding bike?”
The answer to this question is a resounding NO.
If at all, the curiosity to push the boundaries and see how far my Brompton could take me, has pushed me further than I would have done and I completed routes that I would have thought challenging on any bike. I am not saying that with a touring bike I wouldn’t be able to push further, higher and cover longer distances faster. Anyone interested in speed and performance, should probably not choose a folding bike in the first place, but what about those, that I believe being the great majority, who are more interested in experiencing the journey and its sights?
While touring, my longest daily mileage ever has been 160 kilometres and it was done on a Brompton. The highest mountain pass I have ever climbed on a bike was 5300 metres and I did it riding my Brompton. I never meant to set records but these are clear examples that they are more than capable bikes. Provided you avoid, as much as possible, rocky trails or muddy roads where folding bikes perform rather poorly, the ability to go anywhere else is only limited by your willingness to adapt a little and by your mindset.
I am sure there are mathematical formulas that contradict what I say and tell you that according to physics, the resistance of a 16” wheel compared to a 26”, will make you a certain percentage slower but you won’t notice this as much in practice.
As for other aspects that could make it marginally harder, I'll mention a few to be fair and as exhaustive as possible.
They will play a part, especially if riding on strong headwinds. You might find that folding bikes usually allow you to take a position that is less aerodynamic and offer more resistance.
Beyond what is offered as standard, they tend to be smaller and less customisable because they fit with the specific folding system of the bike. You will probably have more limitations in the hand grip and in the position your body can take while riding. While touring long hours each day this can contribute to a less comfortable ride. When your body position and the ability to change it is restricted, it becomes paramount to find a folding bike that is as comfortable as possible right off the bat.
There are folding bikes, especially those at the higher end of the market, that offer wide ranges and lots of gears but these usually come at a higher cost. Generally, folding bikes are more limited in the number of gears they offer and less options will mean a harder ride at times. On my Brompton I tour with 6 gears only which means that I have less choices to adapt exactly the ratios to the terrain I am riding. If this might sound like a great discomfort, I would argue that you also do not need to have 20 or 30. A few gears with well spaced ratios that are soft enough to climb a steep hill and hard enough to push the pedals when descending are all you need.
While they might be a little harder to ride, my conclusion is that folding bikes are perfectly capable bicycles for riding a long tour provided you are willing to make small sacrifices for the flexibility they bring.
