At PUBLIC, we offer two different types of multi-geared bikes. The first type is known as an “internal gear hub”. With an internal gear hub, the chain and gearing system are encased in a sealed mechanism so you don’t have to fret about the chain falling off. The internal hub keeps the chain on and the grime out. Also, an internal gear hub allows you to shift while coasting, back pedaling, or even at a complete stand still. That’s a handy feature if you are hitting a lot of red lights or are stuck in stop and go traffic. If you see an “i” in any of our models, that means they have one of these fancy internal gear hubs like our PUBLIC C7i, D8i, and M7i bikes.
The second type is an external drive system called a “derailleur”. With an exterior derailleur, you can see the chain on the outside of the gears and is most likely the type of gearing you had on your very first bike. Our PUBLIC C7, V7, and R24 bikes have this type of gearing.
Depending on where you live and how you ride, an internal gear hub or external derailleur might be better for you.
Some of the benefits of riding an internal gear hub include:
- Being able to shift while not pedaling – Making starting from a dead stop, like a stop light, much easier. This makes the internal gear hub much more user friendly and welcoming to new riders back on their bike for the first time in years. It’s the only drive system that allows you to change gears while coasting or from a stand still, which is a much more practical option for those commuting in terrains with a consistency of stop and go traffic.
- The gears are not exposed to the elements – Not only does this lead to fewer maintenance requirements, but it keeps your bike looking great. An additional benefit is no more grease stains from gears on your clothes, which is ideal for the work commuter.
- There is less need for maintenance – Thanks to the protection of the internal gear hub leading to less wear and tear. There are no misalignment issues when shifting, meaning no “crunching” of the gears. Tune ups are as easy as aligning two dots, meaning you can do minor adjustments yourself, no mechanical experience required!
- Beautiful bikes like PUBLIC are even more beautiful without a derailleur – Mid-century modern meets the bicycle, with the internal hub keeping the lines clean. The internal hub makes the rear of the bike look as streamlined as the rest of the bike by hiding the gears, cables, etc. The perfect choice for those who want function and fashion.
Our customers love their internal gear hubs, and have been raving about how the perks have been improving their rides.
