What Is a Motorized Bike and What Do I Need to Convert Mine?

Bicycle engine kits are kits that allow you to convert your beach cruiser, road bike, or mountain bike into a motorized bicycle. The engine starts by holding in the clutch lever, pedaling the bicycle, and releasing the clutch. Give the engine throttle and you're off, then hit the kill switch and the engine stops. It's that easy!


Sizing and Fitting

This is a diagram of a bicycle frame to show you where your motorized bicycle engine should be placed.Bicycle engine kits fit most standard 26" wheeled male cruisers, road bikes, and mountain bikes. As long as you have 11" of clearance along the seat tube in the center of your frame, and you have 1"- 1-1/2" diameter frame tubing you should be fine to mount an engine kit to that frame.

Installation requires basic tools:

  • Screwdriver
  • Adjustable Wrench
  • Zip ties
  • Drill

Each engine kit at BikeBerry.com comes with an installation guide to shows you how to easily install an engine kit onto your bike.

What to Consider When Looking into an Engine Kit

There are other factors such as carburetor configuration, engine maintenance, and overall engine functionality that need to be taken into consideration before motorizing a bike.

For example:

  • Two stroke bike engines require the rider to premix gas and oil before riding, whereas a four stroke engine does not require one to premix the oil before riding. This will impact how often you maintain your engine and how much you can push your engine.
  • Some high performance mufflers offer great torque, while others offer a smoother ride. This will impact the performance of your motorized bike should you choose to upgrade your exhaust.
  • CNS High Performance carburetors offer higher performance than standard carburetors, but also require intense tuning and has more complicated installation procedures. This will impact the ability to use the motor with an upgraded carburetor, as it will take advanced knowledge and tuning outside of basic installation if you want to build a racing engine.

Overall, a bicycle engine kit will take your bike to the new level so it's important to consider everything- from engine style to performance and upgrades- before you build.

Though all motorized bicycles and bike engine kits are different, and all have their different quirks to figure out, all engine kits have their sense of fun. Whether you're looking to use an engine to help you on your rides or looking for a fun source of transportation, a motorized bike will get you where you want to go and requires little mechanical skill. From novices to advanced builders and mechanics, bicycle engine kits will give you the power you've always wanted out of your bike!
