Buying Guide: How to Choose an Electric Motor for Your Go-Kart
As you can see, there are many electric go-kart motors on the market and finding the perfect one for your go-kart may not be all that easy. There are quite a number of things to consider and getting these things right is absolutely crucial.
In this buying guide, we’ll take a closer look at various aspects which include motor output, voltage, current, compatibility, components, mounting and price. Understanding these aspects in more detail will enable you to find a suitable motor for your kart and will make your purchase decision much easier.
Output
One of the most important things that you will need to consider is the ability of a go-kart motor to deliver the required power for your go-kart. For electric go-kart motors, its respective power or output is calculated by multiplying torque (Nm) with speed (RPM). To help you further understand this let’s take a closer look at the terms torque and speed. Torque is the rotating force produced by the motor, whereas the speed refers to how many revolutions a minute (RPM) the shaft is rotating with.
Electric go-kart motors with a higher output rating are more powerful and are able to propel your go-kart faster. Higher output motors in the 2,000 to 3,000 watt range are ideal for racing go-karts or adult karts that are generally heavier in weight. They require more power, as they are required to move more weight.
Motors in the middle of the range at about 1,000 to 2,000 watts are for mid-sized karts, which are typically youth karts or average homemade go-karts. Anything below 1,000 watts is considered on the lower end of the spectrum and is ideal for go-karts that are meant for kids or small and lightweight go-karts.
You should also keep in mind that a higher output may not necessarily mean better. This is because high output motors are usually heavier in weight and also require bigger batteries. It can add to the weight of your go-kart and it’s therefore recommended that you find a motor that hits the sweet spot in terms of output to go-kart weight ratio.
Voltage
Voltage refers to the electric pressure of a go-kart motor. The rated voltage of go-kart motors typically range between 24 to 72 volts. The word rated refers to the voltage that the electric motor is designed to operate at reliably. Other parameters such as current and speed depend on which voltage a motor is running at.
For instance, let’s take a look at a 1,000 watt motor with a rated voltage of 48 V, a rated current of 20 amps and a rated speed of 3,000 RPM. The go-kart motor will perform as indicated by these parameters if operated under 48 V. If you operate using only 20 volts for example, the motor will run on less amps, and have a lower speed.
It’s important to note that your batteries should have the same voltage rating as your electric go-kart motor. If the battery has a lower rated voltage, it will lower the performance of the motor. If their voltage is higher than the motor, it can reduce the lifespan of the motor and eventually cause it to fail. Therefore, when picking your go-kart motor, ensure that you have a battery that matches the rated voltage, to ensure that the motor can operate optimally.
Current
An electric current is the flow of electrons through a circuit. An electric motor’s current is measured in ampere or simply amps. The higher the rated current of a motor, the more electrons flow through, which also means that more electricity is required.
To give you a simpler analogy, think of a garden hose. The voltage is the force that helps to push the water through the hose, whereas the water itself would act as the current. The concept of current is important to understand, as it will help you determine what battery size you will need, in order to operate your go-kart engine for a given time.
Think of it as a resource of a power plant. If a battery is rated at 100 Ah (amp hours), it can output 1 amp for 100 hours. For example, if your motor draws a current of 20 amps, it will be able to operate for 5 hours. Therefore, you should pay special attention to the battery in relation to the motor, as it needs to be large enough to supply your motor with enough electricity. You don’t want to be driving your electric kart for 10 minutes before having to recharge it again.
Compatibility
An electric go-kart motor needs to be compatible with other important components, in order to run efficiently and effectively. Some of the most important components that you will need to look out for are batteries and speed controllers. They all need to be compatible with your go-kart motor in order for it to function optimally.
Keep in mind that the output of the motor should be appropriate for the weight of your go-kart. You should also include the driver’s weight in the weight calculation. You also don’t want to overpower your go-kart if it’s meant for kids. Conversely, you also don’t want to underpower your go-kart if it’s meant for racing or if your go-kart is heavier. The best is to find a sweet spot.
You also need to make sure that you have a battery that matches the parameters of the electric go-kart motor. You should ensure that the rated voltage matches that of the battery in order for the motor to run optimally. The same can be said for the speed controllers. Ensure that it’s compatible to get the most out of your motor.
Components
You’ll notice that some of the motors listed in this review contain accessories such as tools, hardware and speed controllers. If you decide to go for an electric motor kit, you will receive all components that are compatible with it. This can help you save time and also ensure that your motor is equipped with compatible components.
If you’re a little more knowledgeable on go-kart motors, you can also opt for a single motor without a kit. This will allow you to customize and source for your own speed controller. I personally prefer to source my own parts, as I like a certain level of customization. If you’re building your own homemade go-karts and are still unfamiliar with electric go-kart motors, I suggest that you opt for a kit.
Mounting
If you look at the electric go-kart motors in this review, you’ll notice that all of them feature a mounting bracket that is attached to the bottom of the motor. A mounting bracket is an important feature, as it directly holds the motor against the frame.
Electric motors for go-karts and other types of recreational vehicles have a mounting bracket for increased practicality. There are also other types of electric motors that don’t come with a mounting bracket. This means that you’ll need to weld a bracket to the motor, or create your own mounting mechanism for your go-kart.
I highlighly recommend that you purchase an electric go-kart motor that already has a mounting bracket in place, such as the motors features in this review. This will make the setup and installation much easier.
Price
Electric go-kart motors are very affordable nowadays. The price of an electric motor mainly depends on how powerful it is. The power of a go-kart motor is generally indicated by the output in watts, which can be used as a reference.
An entry-level go-kart motor starts at about $50, whereas a more powerful motor can go up to about $150. The average go-kart motor costs about $75 – $125. Motor kits are slightly more expensive, as they contain some extra components such as tools, hardware and speed controllers.
- Low Output Motor: $50 – $75
- Mid Output Motor: $75 – $110
- High Output Motor: $110 – $150

What Types of Electric Go Kart Motors Are There?
Electric go-kart motors run on a direct current (DC) and are specifically designed and shaped for recreational vehicles. That’s why you can see that they’re also suitable for scooters, ATVs and bicycles. Therefore, they have a compact design and a mounting bracket that easily allows you to install the motor to your go-kart.
There are also other electric motors that you can use for your homemade go-kart. I’ve seen go-karts run on electric motors from washing machines, lawnmowers, vacuum cleaners and other types of appliances. Some of them may require some modifications as they’re too large or have no mounting brackets. It’s therefore recommended to stick with electric motors that are designed for recreational vehicles.
Should I Only Get a Go-Kart Motor or a Kit?
The answer to this depends on how comfortable you are in sourcing for compatible components. I personally like to customize my go-karts and therefore only choose a go-kart motor without the components of a kit. I’ll then proceed to choose a compatible speed controller and battery.
If you’re unsure about the compatibility of electric components, you’re better off purchasing a go-kart motor kit. Compatibility is extremely important, especially if you’re building your own go-kart. Incompatibility of components can potentially shorten the motor’s lifespan and in worst case permanently damage it. The electric go-kart motors that are featured in this review contain a mix or individual motors and motor kits for you to choose from.
