If you’re good with mechanics then a bicycle engine kit can enable you to transform a standard bicycle into a motorized bike. They also come in handy if you already own an electric bike and you’d prefer to fix your own bicycle rather than pay a fortune to take it to a professional. There are lots of different types of electric bike kits and they differ quite greatly. Not all kits are built equally and some are made specifically for road bikes, cruiser bikes and mountain bikes.
In this bicycle engine guide we look at several types of kit and highlight their best features. We discuss the different types of electric bicycle kit and take a general look at electric bikes, whether they are legal to ride everywhere and whether or not you need a license to ride them.

Best Bicycle Engine Kit Buying Guide & FAQ
There are quite a few different things to consider when buying a bicycle engine kit. Not only do you have to be pretty proficient with a set of hardware tools but you have to understand the workings of a bicycle engine and how it works. Installing a bicycle engine incorrectly could be a waste of your time and money; not only that, but it could also be dangerous. Below we have written a guide covering what to look for when searching for the best bicycle engine kit and why you should consider buying one. We also talk about the different types of bicycle kit and reveal why some people may need a special license to ride one.Keep reading to discover more…
Features to Consider When Buying a Bicycle Engine Kit
- Will you need professional help to build it?
If you feel natural using a tool set and can follow instructions easily then building a motorized bicycle shouldn’t be a problem. It isn’t for everyone though, as the process can take even the most proficient DIY expert with electronic skills, at least a few hours. Take a good look at the kit that you’re buying first and make sure you read the reviews from everyday people who have used the kits firsthand. If you need to enlist additional help that you may need to include this into the final price of the kit.
- How do you plan to use the bike?
If you are only going to be using a motorized bicycle occasionally then you won’t need to find a kit with the largest fuel capacity. Where will you be using the bike? On what type of terrain? Will there be lots of hills? How heavy are you? All of these factors should be considered before purchasing an electric bike conversion kit. You might also want to look at electric bikes and how long they take to charge as well as how many miles you will get out of one single charge.
- What’s your budget?
Electric bicycle kits vary quite a lot when it comes to budget but we would never recommend buying the cheapest on the market. Buy from a reputable company which offer a decent warranty should anything go wrong.
- What’s your tyre diameter?
Size is everything when it comes to electric bike kits – always make sure you get the right size for your tyre.
Why You Should Consider an Electric Bike Kit
There are many reasons why buying an electric bike kit is a good idea.
Here are our favorites:
- They’re better for the environment than a car or motorbike
Let’s face it. Cars are really bad for the environment and walking isn’t always viable. In fact, standard cycling also isn’t viable if you have a long commute or hills on your journey that are super long. This is where electric bike kits really come into their own as they provide an economically-sound way of getting from A to B with minimal harm to the environment.
- They’re fun
The great thing about electric bike kits is that you’re essentially creating a flexible mode of transport for yourself that is really, really good fun! Pedal when you want to or get the motor going when you need a little extra help. Electric bikes can reach some seriously fast speeds, so while you will have to be careful you should also prepare yourself for a fun ride.
- They’re relatively easy in install
This largely depends on how comfortable you are using hardware tools and if you own the right type of tools and equipment to take on the job. Generally speaking though, these are relatively easy to install and should only take a few hours.
- They’re inexpensive
This will largely depend on which type of kit that you purchase, but bicycle engine kits are generally inexpensive when you compare them to other motorized vehicles such as motorbikes, mopeds and cars. Another bonus is that they’re cheap to run too so you will likely save money almost as soon as you start using it.
Types of Bicycle Engine Kits
There are lots of different bicycle engine kits available to purchase and you should do your research before you take the plunge and buy one. Choosing the right type of bicycle engine kit depends on a number of different factors including: your weight, terrain, torque and top speed. Lighter riders (under 200 Lbs) should choose the smallest motor size – 48/50cc are normally fine. If you weigh more than 200 Lbs then a 60cc motor or larger, will better suit your needs. Hills require bigger motors, so take into consideration the terrain in which you will be riding.
Different types of kit…
- Center Mount
Perfect for those who wish to use their motorized bikes locally. If you are a serious hobbyist then this is the right type of engine kit for you. You will need some pretty decent mechanical skills and a lot of patience with this type of kit, but that shouldn’t put off novice builders. These are best for larger bikes.
- Rear Mount Chain Drive
If you’re looking for a more reliable mode of transportation then a rear mount chain drive is the best option for you. These require basic mechanical skills and lots of patience but the end result will be worth it. You can attach these kits to a wider range of bikes, making it suitable for both men’s and women’s bikes. They can be quite noisy though – worth noting if you live out in the suburbs.
- Rear Mount Tire Roller
These are by far the easiest type of kit to install and require less skill and time. Armed with basic instructions and bike tools you should be able to install this type of kit in just a few hours. This is the smoothest ride you’ll find but unfortunately also the loudest.
Best Bicycle Engine Kit FAQ:
Q: What is a bicycle motor kit and how does it work?
An electric bicycle motor kit is a piece of mechanical kit which allows a cyclist to transform a standard pedal bike into a motorized bicycle. There are a number of different kits on the market which all require different levels of mechanical skills to install, but generally speaking they usually require basic skills but a lot of patience. The kits work in different ways depending on how their components. A powered wheel can be installed onto the front or rear of your bike, whereas a drive unit can be installed onto your bottom bracket. Certain motors can even be hidden in your seat-post or attached above the rear wheel.
Q: How many strokes does a bike engine have?
A type of internal combustion engine; a two-stroke engine has its name because it completes a power cycle of two strokes or two up and down movements of the piston during one crankshaft revolution. A four-stroke engine requires four up and down movements (or strokes) of the piston to complete its cycle. Bike engines either have two or four strokes. Two-stroke (or 2-stroke) engines offer more torque and use a gas/oil mixture, they are known to be noisier and emit more exhaust. A four-stroke or 4-stroke engine on the other hand provides a much smoother ride with less exhaust. They also only take gas in the tank.
Q: Are motorized bikes legal?
Unfortunately there isn’t a straight answer to this question as there are a number of different factors that determine whether or not a motorized bike is legal. Factors include the power source (gas or electric) and motor size. It also depends which country or state you are based as the laws change from location to location. In Washington, an electric assisted bike is stated by law as having 2-3 wheels, using an electric motor of up to 1000 watts and a top speed of 20mph. If your bicycle meets these requirements then you are legally allowed to ride your bike anywhere where you would normally be able to ride a standard bike – not sidewalks. If you have a gas powered motor then the rules change and a different law applies. Your bicycle will either fall onto the moped category, if the engine is less than 50 cubic centimeters and produces no more than two horsepower and a top speed of 30mph, motor-driven cycle, if the engine has less than five horsepower or a motorcycle if the engine is more powerful. These will then require registering, a license and vehicle identification number. These rules and laws change according to location so please check with your local government website for details.
Q: Do I need a Licence for a motorized bike?
This depends on where you are riding your bike as the laws differ from state to state. In Washington you are not required to register your vehicle and have a license if you ride an electric assisted bicycle but you have to be overt 16 to legally ride it. Gas powered bicycles fall into various different categories and often require a license. Check with your local government for details before riding on the roads and getting yourself into trouble!
