Bicycle Generator

Bicycle generator (often called “bicycle dynamo”) is a units attached to the bicycle and designed to generate electricity, usually to power bicycle lights.

Before you start comparing different types of bicycle dynamos you need to understand that almost every bicycle generator has the some features.

Common Features of All Bicycle Generators

All generators generate AC current
General power output ranges from 3-6 watts
Most bike generators are only designed to generate 6V and only a few are designed to generate 12V
Most generators will reach an optimum level of power output at 12-15 miles per hour.

Did you know...?

Did you know that bicycle dynamos are environmentally friendly?

Since they run on kinetic energy produced by your pedaling, no fuel sources are necessary to power the dynamo. This means that dynamos neither deplete the Earth's energy sources nor produce pollutants. If you want to go green, install some dynamos on your bicycles!

Two Types Of Bicycle Generators

There are two major types of bicycle power generators: Hub Generators, and the Sidewall Generators.

Hub Generators

This is often described as the best type of bicycle generator for bicycles. It is built directly into the hub of the bicycle wheel.

Major advantages

Very discreet: This type is both elegant and non-imposing.
Highly Efficient: Since there is no friction involved, (compared to other types of generators) this provides an excellent power output.
No damage to the tire: The in-built design of the bicycle hub generator prevents it from damaging the tire.
Not affected by the elements: Unlike externally mounted generators, the hub generators are shielded from the dirt, dust, water and other elements.

Major Disadvantages

Difficult to install: hub generators are notoriously difficult to install because you need to build a custom wheel. Moreover, Compared to external motors, it is also much heavier.
High Cost: Even a second-hand motor could easily fetch around $40+ (excluding cost to build the wheel). Therefore, if you are looking for a bicycle generator keep in mind that the hub generator is the most expensive variant.

Sidewall Generators

If you are looking for lightweight generators, sidewall or bottle generators are your best choice. These are pretty affordable too. A sidewall bicycle generator works best on rough or uphill terrains since they can generate electricity on slow paces.

Major advantages

Any-time use: Unlike hub generators, you can choose to use it at anytime. If you are not using it, all you need to do is disengage the generator.
Compact and powerful: For a typical bicycle generator, it is both compact in size and powerful in terms of energy output.

Major Disadvantages

Regular Maintenance necessary: Since it is mounted externally, you have to constantly keep the sidewall generator clean.
Short Lifespan: The best of these generators last an average for a few thousand miles.
Tire Damage: Since they are designed to make contact with the side of your bicycle tire, they can do some damage, especially if you have lightweight tires.

How Does a Bicycle Generator Work?

You may already know that the generator sends power your bicycle lights to turn them on; but do you know how and where it gets the energy?

When a light generator like the Bicycle Dynamo Generator is installed or attached to the bike's gears which are attached to the wheels, it gathers enough energy to make the lights go on. As you step on the pedals, you are automatically creating electricity. Talk about saving money and the planet!

Bicycle Generator Vs. Batteries

Compared to using batteries, using a light generator can help you save more money. Imagine, all you need to purchase would be the generator set itself and then nothing else; unlike using standard batteries that you need to replace over and over again.

You can rely on bicycle light generators to light your way and can even power a 3 Watt light bulb or even higher. Another thing, bicycle generator such as the Bullet Generator Set is not too sensitive and will still work even on the bumpiest or the roughest of trails.

Now, with this type of bicycle lighting system, you will never worry about being left out in the dark without the proper lights on.

Installing Your Bicycle Light Generator Properly

As soon as you have your 12 Volt Generator Light Set, the next step is for you to be able to properly install it on your bike. And here is how:

First, consider the frame and the size of your bike. So be sure that you have your bicycle light generator positioned properly.
Second, study the kit! Never attempt to put everything together without reading the instructions.
Third, clamp or fasten the generator onto the frame of your bike, in a vertical angle to make sure that the roller connects with the wheel.
Lastly, fit the lights and test to complete the circuit!
