Electrifying your bike: a good idea?

Man electrifying his electric bicycle.

Can't afford to invest in an electric bike? No problem! Thanks to our "electric bike" kits, you can electrify your two-wheeled vehicle. Yes, it's possible!


It's a responsible alternative, but above all it's less expensive! All you have to do is choose a kit and master a few tools!


So, how to do it ? Which kit to choose and where to buy it? Can anyone install it? Don't worry, it's easier than it seems. We make the point!


Why electrify your bike?

Save money

By converting your bike into an electric bike, you can save hundreds or even thousands of euros. Not bad, eh? This is also the case if you opt for a second-hand bike or refurbished (like at Upway 😉 ).


An electrically assisted bike costs on average 2500€, while conversion kits range from 200€ to 1000€ for the most advanced. This is equivalent to dividing the cost, on average, by 3 or 4.


Do not abandon your bike

Let's face it, parting with your bike is not always easy! You have spent time with it, travelled many kilometers, crossed rough roads,... You love it, and we understand you!


So why get rid of it? By converting your bike, you ensure that you have an EAB that suits you. In addition, you are doing something ecological and you avoid over-consumption.


Another aspect not to be overlooked: kits can be assembled as well as disassembled. What does this mean? You can easily replace cables, the battery or make other modifications. Child's play compared to electric bikes!

What is an electric kit?

It is a kit that usually combines a motor and a battery. It allows to transform a bicycle into an electric bicycle. The action of pedaling will start the motor, that is to say the assistance to pedaling.


The kits are designed to be installed directly by an individual. However, if you have any doubts or if you are struggling, do not hesitate to contact a professional.


Three types of kits are available to power your bike: front wheel motor, rear wheel motor and crankset motor. You can choose it according to your uses, your needs but especially your bike.


The composition of most kits :

  • an electric motor (which theoretically should not exceed 250W)
  • a lithium battery
  • a controller
  • a pedal sensor
  • a console
  • cables

If needed, you can add additional parts such as mechanical brake levers, cables needed for mounting or a throttle.

Do the kits fit all types of bikes?

Most bicycles are compatible with the installation of a kit, whether you have a MTB or a city bike. To be sure of choosing the best kit, it's best to know the bike's technical specifications.


Check a few things: the distance between the wheels on the frame, the size of the tires, the size of the rims, the pedal box, the clamping or the width of the frame tips. Compare the dimensions with the kit you want.


How to transform your bike into an electric bike? 

There are several kits to electrify your two-wheeler: front wheel, rear wheel or pedals. It's up to you to choose the one that best suits your needs and uses!


Here's how to tell them apart and discover some of the best kits available on the market!


Front wheel motor

This is by far the simplest solution, but also the least expensive! You don't need a lot of tools or to be an expert in DIY. Simply remove the wheel and replace it with a new motorized one. Add a sensor to the crankset, and you're done!


The bike is electrified in a few minutes.


But it has a significant disadvantage. With an important weight distributed on the front of the bike, the balance is precarious. Even more so when the battery is discharged. A slip is quickly arrived!

For whom?

This mechanism is mainly suitable for folding bikes and electric city bikes. Ideal for small budgets and short distances. Don't count on it for rough roads or rainy weather!

An update on the legislation

Before investing in a kit, it is essential to know the regulations in force. First of all, rest assured that using an approved electric bicycle kit is legal. However, to be used on public roads, you must respect a few conditions:


  • The motor power must be 250W maximum
  • Speed must be limited to 25 km/h
  • The assistance must be triggered when pedaling and cut off when the pedaling stops.

If the motor exceeds 250W, the electric bicycle must have insurance and a license plate. You will not be able to use the bike paths. The cyclist must wear a helmet. In the eyes of the law, these bikes are classified as mopeds, speed bikes

Where to buy your kit ?

Are you convinced? You want to buy an electric bike kit? Internet will be your best friend! The e-commerce sites offer a wide choice: Amazon, eBay, Cdiscount, Bafang,...


However, if you prefer to go to a physical store, there are some that specialize in this area, especially in large cities.


Also note that the kits can be eligible for the VAE bonus from the State! Take a look at it !


Electric bike or conversion kit?

If you're hesitating between buying an electric bike or converting your old one, here are a few arguments that could tip the balance! Obviously, choosing a "ready-to-use" electric bike has a number of advantages:


Assembly: A definite advantage of buying a ready-to-use electric bike - if you find one that fits your needs - is that you can assemble your machine without having to do any work. If you're not particularly handy, this is probably a better option for you. On the other hand, if you buy from a big name in cycling, your bike will be more reliable since it will have undergone a battery of tests and will meet European safety standards.


Proper construction: think of your safety! The frame of a conventional bike may not be suited to the forces that will be exerted after your kit is installed. The addition of a battery and motor will have an impact on the overall balance of your bike, which is something to consider if you're going to do this. The addition of the motor on the front wheel, for example, will make the control of the bike a little less predictable and you will need to adapt your riding to this new parameter.


Finally, "plug and play" electric bikes are equipped with brakes, bearings, chains and even tires specifically for the higher speeds and weights associated with the presence of the battery and motor. This may not be the case if you convert your bike!


Warranty: If you decide to buy a conversion kit, it is unlikely that you will benefit from the same warranty as those provided by the EAB manufacturers. If you buy an electric bike in Belgium, you benefit from a two-year legal warranty and some brands offer even longer warranties!


An important point when you know the price of VAE batteries.


To conclude: The main argument for choosing a conversion kit over an electric bike is cost. An electric bike new will of course be more expensive than a conversion kit, but if budget is no object, you should still go for a bike designed to withstand high forces and speeds. Your safety and comfort are at stake.


FAQ : electrify your bike

Should I choose a kit with a pedal motor or a wheel motor?

It's easy! When you buy an electric bicycle, it must meet the European standard NE15194. That is to say that the power of the EAB is limited to 250W, its assistance to 25 km/h. The motors are therefore all the same regardless of the price.


A kit will allow you to choose your engine and your power then to install it on the bike. This allows you to adapt it to your terrain: road, city, mountain, off-road,...
