    What are internal hubs?

    It has several names like the internal-gear hub, hub gear, gear hub, or just internally-geared hub.

    It means a gear ratio changing system available in bicycles and compliments with epicyclic or planetary gears.

    It is not the bicycle in itself but a system for changing the gear ratio in a bike. The short form of the name is IGH, and it is an alternative to the Derailleur bikes.

    The evolution of Internal Gear Hub and Derailleur

    The IGH invention surprisingly came before the Derailleur bikes, and the first patent was out in the year 1895 in the USA. Ten years later, a French cyclist invented a rear derailleur. Both models gear-sifting systems had two speeds.

    Though the derailleur was ten years young than the IGH, it employed more technology. The simple derailleur model had more gears with a wide range. On the other hand, IGH had and maintained three for decades. During this time, derailleurs became dominant in the market.

    However, the domination didn’t last long, as things began to change rapidly. In the years preceding their invention, IGH technology was progressing rapidly and significantly. The two types of bikes now have the same gear range and performance.

    How does the internal hub gear work?

    They operate under the principle of epicyclic or planetary cycling. It requires three main components to function, and they are:

    1. The planetary gears.
    2. The sun gears, and
    3. The ring gears.

    The sun gear is attached and fixed to the gear axel hub, and the planetary gear revolves around it.

    The ring gear surrounds the planetary gears and has inner teeth.

    One of the three parts acts as the input mechanism. The last gear is the fixed or the reactionary part. The input and output mechanisms in the three components will determine the level of speed on the machine. It either increases or decreases on which of the three acts as the input/output.

    The difference in size between the sun and ring gears determines the speed ratio of the bike.

    The models with more than three speeds come with two or three planetary stages. In addition, it has to have more than two sun gears.

    What are the benefits of internal hub gear?

    These bikes offer a lot of benefits to the user. Probably, these are the things you should know beforehand as you plan to buy the bike. The benefits of IGH include the following:

    Better balance

    The gear hubs are in the lowest part of the frame. It is in the center area of the bike. The internal gear hub determines the center of gravity by placing it in the middle.

    The bikes with internal gear hubs have a better balance because the center of gravity is also in the middle. It makes these models better than the derailleur.

    Durable

    Most gearing systems have an enclosing unit that dips and bathes in oil at all times. The housing prevents them and their parts from exposure to environmental hazards such as mud, snow, rocks, water, and other harmful elements.

    In contrast, the gear hub system does not wear and tear fast like the derailleur system and increases its useful life.

    Regular and proper lubrication can help the IGH last for a lifetime with minimal maintenance.

    Shifting the gear without pedaling

    These bikes allow for changing the gears without pedaling or when the bike is stationary. Derailleurs do not have this feature, making the IGH bikes the best models. Shifting them while it is not in motion allows you to place them in high gear from a non-motion or stop position.

    Minimum maintenance

    The only maintenance that the IGH bike needs are a change of oil. Do it regularly and at least once a year to preserve the gear, hub, and parts.

    The recommended procedure is to change it after six months from the date of the first use. Subsequently, you can change it at least after every one or two years, depending on the intensity of use.

    If you use your bike daily, the oil will go bad sooner than the one not in regular use. Ensure you assess the quality of oil after every six months to determine its worthiness.

    Reliable

    Its reliability is because all the parts responsible for shifting are on a sealed and protected unit.

    There is no risk of having bent, muddy, or broken gear that may impact the changing of gears. The protection ensures smooth shifting at all times, hence improving reliability.

    Buyer’s Guide

    best gear hub

    Buying an internal gear hub bike can be challenging because there are several models in the market. Each of the products offers a unique feature from the rest of the others. However, there are a few things to look out for when selecting the one to buy. We will discuss each one of them in this section.

    The gear ratio

    It is the most important thing to check as you plan to buy an internal gear hub bike. Ratios differ depending on the model. Some have a maximum of 200%, while others offer 500%.

    The gear ratio is the difference between the highest and the lowest gear. The calculations are on the distance the wheel covers for every pedal you make in such gear.

    Knowing the gear ratio will inform you if it is the right gear hub. The nature of the terrain should also tell you what kind of bike to buy.

    A bike with a limited gear ratio would never be ideal for riding up the hill. You may end up walking beside it rather than riding!

    On the other hand, you need a bike with less gear ratio if riding on flat surfaces such as paved walkways and indoor riding. Understanding this would help you choose your model wisely and with caution.

    Generally, it is not right to buy a bike with a limited gear ratio because you never know when you will decide to go riding uphill.

    The assembly

    All the internal gear hubs have the parts attached to the inside of the hub shell. The assembly involves fitting the spokes to the rim and the gear hub.

    Another item is fixing the shifter cables to the type of gear hub the bike has.

    The next item is the attachment of the levers and brake cables, depending on the gear hub. It should be compatible with either of the following: the coaster brake, drum brake, or rim brake.

    The final part of the assembly is ensuring that the gear hub has sufficient oil and that the chains have lubricated adequately. Oil and lubrication keep the part moving effortlessly and with a lot of ease.

    The lubrication

    Depending on the model of your vehicle, you can either use oil or grease to lubricate the gear hub. Checking the user manual will help identify what the manufacturers indicate as a recommended lubricant. It also shows the schedule to change the oil.

    Always check the manufacturer’s manual before performing any maintenance to ensure you have the ideal lubricant.

    Placing the wrong type of lubricant on the hub shell and the chain wheel could spell doom for your bike. It is always advisable to double-check the manual to ensure you get the correct lubricant for your machine.

    Maintenance

    Maintenance of costs of IGH bikes is low, and it only involves the oiling of the hub and its components. You can either use oil or grease to do the task.

    Most bikes use grease for maintenance and some work with oil. Those with three to eight gears use greasing for maintenance purposes. Those with more than 8 are oil-based.

    The bikes that use grease require cleaning and regreasing at least once or twice every two years. It also depends on how you use the bike.

    If you use it daily, the frequency of cleaning and greasing should be an annual event, failure to which the hub will suffer damages.

    The oil needs to be changed regularly for those bikes that use it for maintenance. Maintenance needs to be done once annually by draining the old one and replacing it with a new one. It helps maintain the optimum performance of the gear hub.

    You also replace the seals every once in a while, or when changing the oil. It helps prevent the lubricant from leaking. You may not need to change it regularly but depending on its condition.

    Maintenance of a bike is an easy task. You only need to identify the appropriate lubricant for the work. However, if it is your first time, call in an experienced person to avoid getting into a mess. Another alternative is to take the bike to a garage for maintenance.

    The sprocket and the chain wheels

    Sprocket comes in various sizes, and choosing the right one, plus the matching chain wheel, can either lower or raise the overall range of the IGH.

    Ensure you choose the most appropriate one, or the gear ratio might not match. Consider the terrain you would like to ride your bike before selecting the sprocket and the chain wheels.

    A wrong selection can make you not enjoy the rides and reduce the effectiveness of the bike.

    Frequently asked questions – (FAQs)

    Are IGH bikes better?

    These models are more reliable than the derailleur. The technology employed in the IGH is more advanced and requires less maintenance. Their gear ratios are also some of the best.

    It is fair to say that internal gear hub bikes are better than derailleur models, going by the factors above.

    How long should it take before carrying out maintenance on the IGH bike?

    Maintenance involves greasing the hub and its components. Some models use grease, while others work best with oil.

    Maintenance depends on many factors, including the frequency of usage and the terrain. Grease-based hubs will require cleaning and regreasing at least once in two years. On the other hand, the oil models need draining and replacing with a new one every year.

    How long do IGH bikes last?

    It depends on how you take care of the bike and its hub. However, it can sometimes last for several years without any maintenance.

    The most basic hubs can last up to 50,000 without requiring any service. On the other hand, oil-based hub bikes will require annual servicing to keep them running smoothly.

    Why do IGH bikes fail?

    They only fail if the user fails to do maintenance. Others include overloading the bike, inadequate lubrication, and installing the axle nut tightly or loosely. All these can make the bikes fail to function optimally.

    What can cause the hub to crack?

    Too much heat can exert too much pressure on the hub, causing it to break down. The friction within the bearing during high-speed rides goes to the gear hub, which can break down.

    You can avoid overheating in the hub by ensuring it has enough grease or oil at any moment. It helps reduce friction arising due to constant scratching of the moveable parts inside the gear hub.
    Replace the hub when you find it cracked before damaging other parts in the system.

    Conclusion

    Internal gear hub bikes are some of the most advanced products today. They came late than their derailleur counterparts, but their technology elevated them to the top.

    There are several models in the market, and choosing the most appropriate one can be a daunting task.
