6 Best Bicycle Motor Kits 2021

It is actually surprisingly straightforward to get your bike into a position where it can have a motor. The best motorized bicycle kit is easy to install and will have you travelling with no effort at all before you know it.

While getting a motor kit is an obvious choice for those that want to upgrade their bike it isn’t so easy to choose between all of the available options. To help buyers make their way through the choices, we have included the top ten available motor kits and some unbeatable tips that will assist in their decision.

Consider This

  • Motor Control. There are two main categories when it comes to how the rider will control the motor: throttle or pedal-assisted.
    • Throttle. This is when the motor does most of the work but in some cases the rider will be able to add pedal power to assist with difficult terrain.
    • Pedal-Assisted. This type of control monitors how hard the rider is pedaling and provides more power when it is needed and less when it is not.
    • Combinations. There are a few available products on the market that can provide both of these settings. These motors rely on one as a primary control and the other as a backup system.
  • Gas or Electric. Our list contains examples of both. It is important to check your state regulations first before making a choice between the two. Generally electric ones are more expensive but they are also quieter and generate less pollution.
  • Motor Placement. Different manufacturers have designed their motors to be mounted in various places on the bike. The easiest ones to install are those that are placed on the rear tire. They only require a basic understanding of mechanics to put in place but they are louder and less efficient.

For those that know what they are doing you can opt for a rear-mounted chain driving motor that is quieter but takes a little more time to install.

Finding a Good Kit

The most important factor when you are finding a motor kit is to think about the size that you will need. Here is a short guide to the ideal type of engine you need for specific situations:

  • 50cc. This is the perfect size for travel on relatively flat terrain and with an average size rider. Sometimes with motors of this size you would need to pedal once you reach a hillier area.
  • 50cc-80cc. For the heavier rider or when the bike will need to deal with many hills, this size range is the better option.
  • 80cc +. Anything higher than 80cc will start providing speed that might be too much for a bicycle. While it seems that faster is better, even 20mph can seem too fast on a small bicycle. Save any motor choice of this size for extreme circumstances.

The best bike motor kit will be the one that gives you the right size motor for as many possible situations that you will encounter. Carefully consider the use of the bike and then you’ll have a clearer idea of the motor size you need.
