What To Look For In The Best Electric Bike Conversion Kit (Our Buying Guide)

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.

What Types Of E-Bike Conversion Kits Are There? 

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.

Wheel Hub Conversion Kits 

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.

8.4/10Our Score

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 

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.

Are E-Bike Conversion Kits Worth It?

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? 

Advantages Of An E-Bike Conversion Kit 

  • You can keep your bike - Perhaps the best part about choosing to convert your bike rather than buying a new one is that you get to keep your old bike, conversion kits are also pretty easy to remove if you ever want to change your bike back. 
  • It's customisable - Whether you want an extra high powered motor or long-range battery, electric bike conversion kits are customisable to your specific needs rather than buying a pre-set electric bike. 
  • Saves you money - Not always but an electric conversion bike kit can save you money rather than buying a whole new bike frame.

Disadvantages Of An E-Bike Conversion Kit 

  • Added weight - By installing a conversion kit on your bike you will add a large amount of weight to your bike.
  • Installation takes time - Installation of a conversion kit takes a lot of time and some previous knowledge of electric bikes.
  • They can look messy - Conversion kits never look as seamless as e-bikes from the shop no matter how well you try to hide the wires.

What Influences The Power Of Your Electric Bike Conversion Kit? 

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. 

The Watts 

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.

The Volts 

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.

The Amp Hours 

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.

What Battery Power Do I Need In My Conversion Kit? 

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.

Other Features To Consider In Your E-Bike Conversion Kit

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. 

  • Power - As we mentioned above, checking the motor type and motor power of your kit is important since it determines what you'll be able to use the bike for. For commuting, a 250W motor with let us say 40 newtons of torque is sufficient, but for mountain biking with inclines, you need something stronger. 
  • Sensor - In an e-bike conversion kit, you will either find cadence sensor types or torque sensors. Cadence sensors will be able to sense how fast the pedals are going and apply for proportional assistance while torque sensors give power according to the force applied to the bike, making it feel more natural, out of the two, torque sensor types are more desirable.
  • Compatibility - Always check if your conversion kit will fit your e-bike before committing, make sure the dropouts of your bike will be able to fit the motor and the bottom brackets for mid-drive motors are compatible with the bike's cassette.
  • Accessories - Many of the best conversion kits come with accessories such as an LCD and cranks, some might even include tail lights, make sure your kit is good value for money.
  • Weight - Be cautious that e-bike conversion kits add a lot of weight to your bike, always check the total weight your kit will add before purchasing, the bigger the battery and motor, then the heavier the weight.
  • Warranty - Always ensure that your e-bike conversion kit has some kind of warranty on its parts, especially on the motor and battery, as these are the most expensive parts of conversion kits.

Frequently Asked Questions About Electric Bike Conversion Kits 

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.
