After reviewing our top three e-bike conversion kits, we can now move on to learning more about these conversion kits and what should be looking for in the best kit.
Down below in our buying guide, we will cover the different types of e-bike conversion kits out there, what influences the power of your conversion kit, what battery you need for your conversion kit, other features to watch out for and more.
On your hunt for the best e-bike conversion kit with a battery, you've probably realised that these kits come in three different types; front hub, mid-drive and rear hub kits.
These relate to the motor position and where it will be installed on the bike.
We've gone into more detail about the different types of kits below.
These kits are the easiest type to install, front-wheel kits are especially easy to install and give the feeling as if you are being pulled along by the motor, this is why they are often the cheapest too.
Rear hub wheel conversion kits are much more desirable than front-wheel kits, although a little harder to install, these give motor assistance directly to the rear wheel when you pedal, giving a more natural and boosted feel.
Mid-drive conversion kits are often more expensive than wheel hub conversion kits and are harder to install, but they do produce the best performing electric bike.
These motors will be attached directly to the drivetrain of the bike, allowing the motor to work with the pedalling of your bike giving you the quickest response of assistance.
The only drawback of these conversion kits is that they can wear down the drivetrain of your bike quickly.
Before investing in a conversion kit for your bike, you might be torn between just buying a whole new e-bike, or spending the time converting your own.
Some e-bike conversion kits with high power can even cost a similar price to an affordable e-bike, so what makes these conversion kits worth it?
When choosing the power you need in your conversion kit, you need to consider three different factors; the watts, volts and amp-hours, these all determine how powerful your bike will be.
We've gone into further detail down below.
This measures the power input and output of your electric bike motor, when choosing your e-bikes motor you need to consider the continuous watt rating and peak watt rating. To work out wattage, you can get this calculation by multiplying the amps and volts together.
Volts measure the amount of energy which comes from the battery in your electric bike to the motor and how well the bike responds. The higher the volts the speedier the motor typically.
This determines the amount of energy that your battery can hold, the higher the amps then the more power it can hold and the further your e-bike will be able to go. The bigger the amps and voltage the faster your e-bike will be able to accelerate.
Choosing the right battery power is one of the most important parts of your conversion kit, avoid budget batteries at all costs in conversion kits, otherwise, these will ruin the quality of your e-bike.
To choose the right voltage for your battery, you must make sure it's matched to the motor voltage in your e-bike, too high could even start a fire. Picking a matching voltage or within the higher end will ensure your bike performs fast.
The higher the amps of your battery then the more current it will have, therefore the more torque the e-bike will have. Always take the estimated range of e-bike batteries with a pinch of salt, many factors affect the watt-hours of a battery such as the terrain and weight.
Now we covered the main types of e-bikes conversion kits, the pros and cons and how to choose your battery, let's move on to some additional features which you should be considering in your conversion kit.
How much do electric bike conversion kits with battery costs?
This depends on the power of the battery combination with the motor as well as the type of motor, whether rear wheel kits or mid-drive kits.
Can you turn any kind of bike into an e-bike?
You can convert any bike into an electric one, but your current bike should be strong enough to handle the weight and power of the motor, preferably a bike with steel dropouts is better for conversion.
What type of brakes should I put on my electric bike?
When converting your conventional bike into an e-bike it's best if you equip it with either double disc brakes or hydraulic disc brakes rather than standard rim brakes.
Our number one electric bike conversion kit is the BAFANG Electric Bike Conversion Kit, this kit has a wide range of motor options, and is a reliable fit for bikes with a 27.5-inch wheel, making it great for mountain bikers.
We also recommend the more affordable Viribus 48V 1000W 26" Electric Bikes Conversion Kit which still comes with an excellent bit of power and accessories, do be aware you need to buy the battery separate from this model, however.
