If you want to transform your normal bicycle into a functioning electric bike, then there are factors you should consider. That is because electric conversion kits come in different designs and types. It’s up to you to determine how you want your electric bike to function after converting it. And this will depend on what you choose.
Read through the following buying guide to understand the necessary factors to consider if you want to enjoy your rides.
Choosing the right kit
An e-bike conversion kit is a great investment. And there are several ways to maximize it.
Firstly, it is important to find out the use you will give to it. Will it be only to commute? Will you ride in the hills?
What distance will you travel with it? All these questions are answered with the technical features of the electric conversion kits.
There are different types of electric conversion kits available on the market for your preference. You can choose from the wide range of options; the front and rear wheel e-bike, mid-drive, friction drive, concealed or folding conversion kits. Here are more details about each of those types.
E-bike wheels are the most popular ways to transform your bicycle into an electric bike. The front wheel conversion kit means that you replace the anterior wheel with another wheel that has a special gear or hub. The rest of the bicycle remains the same as it was before.
Here, the battery is mounted at a different spot in order to distribute weight evenly across the bike. If you place the battery in the same spot as the motor, you will struggle with all the weight sitting on the front wheel. Therefore, it is ideal to mount the battery centrally or at the rear position of the e-bike. The kit includes a front wheel featuring a hub motor, speed controller, battery, electric brakes, a throttle, and LCD display panel. Some models may also include a pedal assist sensor.
The front wheel motor has less traction because there is little weight on the front wheel. This means that it can be difficult having control over traction. A 36V hub motor on a 26-inch wheel size will provide decent traction.
What’s more, front wheel e-bike rarely gets flat tires. This is because they will kick off sharp objects on the way to prevent punctures. It is worth noting that this type of e-bike is the simplest to install.
If you are planning on riding up the hills or off-roading, then a rear wheel e-bike is the most ideal solution. This is because of the excellent traction control the rear wheel e-bike provides when pushing on the throttle. It features a rear wheel including a hub motor which is hard to notice as it resembles a large conventional bike hub.
In addition, there is a battery, electric brakes, speed monitor, LCD display panel, throttle, and a pedal assist. Also, you have the option of mounting the battery to the frame. Built-in batteries on the wheel or those that mount on a rear rack exert a lot of weight onto the back wheel. This, in turn, causes sudden wheelies when you put on too much power.
However, the rear wheel kit limits the selection of pedaling gears. You only have to work with derailleur gears and not the integrated hub gears.
Since the rear wheel and spokes are exposed to massive stress, it becomes quite difficult for the rear wheel to last longer than that of a conventional bicycle hub. Therefore, you are required to spend extra on high-quality components in order to prevent such occurrences. That means that the rear wheel least suits those who are on a budget since it requires a lot of maintenance.
This is another popular type of electric bike conversion kit that looks similar to the original e-bike design. In the mid-drive kits, the battery and motor mount to the frame. The motor is usually attached to the bottom bracket.
In addition, the kit has its weight down on the low to ensure a stable and smooth ride. But the motor is often susceptible to damage since it is exposed and closer to the ground when off-roading.
With mid-drive, the rear wheel is used to drive which means it provides excellent traction control. This makes it perfect for touring with your electric bicycle.
The mid-drive differs from the rear wheel kit in that the spokes on the rear wheels don’t get much stress. This is due to the fact that the weight of the motor is evenly distributed throughout the bike and it doesn’t have an effect on the wheel build.
You can enjoy your rides up steep hills thanks to the geared motor. This means that you can easily lower the riding speed when going up sharp hills.
However, the mid-drive also has a few downsides. It is a very costly electric conversion kit and is quite complicated. There is so much weight applied on the drive chain meaning the chain, rear hub and gear require frequent maintenance and sometimes replacement.
Friction drive is an e-bike system that rotates the roller which is compelled by the bicycle tire. This was first invented in 1899 and is gradually gaining popularity among the best e-bike conversion units.
The motor and roller are located on the rear wheel and uses friction to propel the bike. Since the builds are attached to the seating area, it becomes quite easy to install and remove the seat and drive without using tools. Since it is also compact and lightweight, it is ideal for those who wish to leave their bicycles outside.
However, the power applied to a friction drive has its restrictions. That is because acceleration is determined by the contact between the roller and the tire. If you increase the drive’s peak power, then the roller might spin out leaving you frustrated.
You should know that the starting torque of the motor is responsible for swinging and taking hold of the tire. The rolling shell will pull in deeper into the tread the moment it is in contact with the motor.
If there is nothing powering the motor, then it doesn’t gain contact with the tire to eliminate drag when pedaling. This allows you to use your bicycle in its regular state.
As the name suggests, concealed kits are units that hide inside your regular bicycle to transform it into an e-bike. This type is ideal for those people who want to retain the appearance of their conventional bicycles but still enjoy the thrills of an e-bike.
Here, a motor and battery are placed inside the tube of the seat and drives on the bottom bracket. This is the latest design of electric bike conversion that is also quite expensive.
The concealed kit lets your bike ride quite the distance without other road users knowing that it is actually an electric bike. They will just be amazed at the speeds of your bicycle, not unless you tell them that it contains the kit.
To fully conceal something means that it is compact enough to stay low key. For that reason, both the motor and battery of this kit have a compact and lightweight design. Don’t let the size of the motor and battery fool you because they are quite effective and that’s why the concealed kits are that costly.
Folding conversion kits are a great way of converting your folding bicycle into an electric bike. The kits feature a powered hub located in the front wheel. Also, it includes a battery in a bag that is fixed at the front area of your bicycle.
The motor is usually lightweight and you also have a choice to either use a twist grip throttle or a thumb throttle. In addition, they provide high speeds to make your riding exciting. Like the front wheel kits, installation is quite simple and require very little tools.
Front or rear hub/wheel – which is better for an electric bike?
Initially, there is not a significant difference that both systems offer except for the highest traction that rear wheel may deliver. If you are planning to use your bike to climb hills or your commuting route includes many ups and downs, then perhaps a rear model would be better for you. Besides, you should check your bike in order to verify which option fits better to it.
A motor is what powers any electric bike and allows it to function the way it does. Therefore, you need to pay close attention to the motor of the conversion kit you are buying. The kits come with different sizes of motors whereby performance is determined by the size.
Larger motors are more powerful compared to smaller motors in conversion kits. This means that they have great speeds and are efficient. When choosing what motor size, you should first know what you will be using the e-bike for. You require a more powerful motor if you are planning on taking long rides on roads in the countryside. This will also provide you with massive speeds when racing with friends.
However, if you will be using the e-bike in busy streets, then a less powerful motor is most ideal. The number of watts and volts on a motor determine how powerful the unit is. The higher the watt-rating, the more powerful it is.
Also, the rpm rating also determines how powerful the motor is. If it has a high rpm, then it powerful.
Although motor efficiency is showed in percentage, the best way to measure the efficiency is by checking the maximum speed you can reach. As you get the higher speed, you will have more efficiency. Recent models may reach up to 45-46 KMH, but those with 25 and above would be enough to take you anywhere you want.
Another way to verify the efficiency is the number of watts of the motor. When they reach between 500W and 1000W, they guarantee high power. Anything below 500W is only suitable for flat roads and short rides.
The battery in a conversion kit provides energy for the motor. Therefore, it is another key factor you should prioritize when looking for a kit. Just make sure you choose a battery that is able to handle the current of your motor controller.
If the battery has a low current rating and works on a high rating motor controller, then the circuit will automatically shut off at full throttle. That also causes stress to the battery hence reducing its lifespan. The vice versa is also true.
Go for a kit offering sufficient battery capacity to cover your trip successfully. This is determined by both the watt-hour capacity and energy needed per kilometer. For instance, if your bike consumes 10 W*h/km from the battery and you have 720 Watt-hour battery, then you will cover a distance of 72km. In other words, the more energy is exerted, the lesser the mileage.
Brake levers are also an important factor as they determine safety while riding on your e-bike. When braking, the motor goes off first. This happens because there is an integrated sensor in the lever that spots when you pull the brake cable.
It then sends a signal directly to the motor controller for it to switch off the motor. The brake levers are placed onto the handlebar of your bike for quick and easy access.
Pedal Assistance System
Pedal assistance system in an e-bike is useful in controlling its speed. It operates with a sensor attached on a pedal crank or bottom bracket and detects pedal torque or cadence. This then passes information to the controller in order to accelerate.
When the pedal crank turns, the sensor gets the rate at which you are pedaling. If the pedal cadence is fast, then the controller will ensure the motor spins as fast. Electric bikes come with a given number of pedal assist settings and the most common are these three; low, medium and high.
Low pedal assist provides more pedal power for intense workouts. Medium provides great balance on the pedal power and motor power. High pedal assist lets you get to your destination fast using minimal effort.
Torque sensor pedal assist is the latest system offering advanced features. With this, the amount of torque applied is directly proportional to the power needed when pedaling (acceleration, hill climbing, steady and more). This proves that it is the best compared to the traditional systems.
What’s more, a pedal assistance system also helps those people who are looking to exercise with an electric bike. It ensures that you never stop pedaling in order to keep moving with your bike.
The throttle is also another method used in an e-bike to control its speed. The throttles in an electric bike resemble those found in a conventional motorcycle as they are fixed on the handlebar. To operate them, you either use the twist or thumb action.
The price is one of the main reasons that attract buyers to get ebike conversion kits. Most of them are very competitive. An e-bike conversion kit with a battery may increase the price, but it will give you the benefit of installing the kit at the moment you receive it.
It also guarantees that you comply with the specifications of the manufacturer. It doesn’t make any sense to buy a cheap electric bike conversion kit if you have to buy all the missing parts for a higher price. So, be smart and verify the total cost.
Electric bikes are gaining popularity all around the world but their price makes them unaffordable to many. That is why the common method is getting an electric bike conversion kit to transform your regular bicycle into an e-bike. This works best for people who already have good bikes that they don’t want to get rid of.
Instead of spending a large sum of money to get an e-bike, you can use a conversion kit on a regular bicycle. Conversion kits are significantly cheaper than purchasing electric bikes. Also, you get to mould an electric bike to your specification depending on how you want to use it.
With an electric bike, that option is not available. You get what you get. What’s more, you can change the conversion kit or use it with other bikes.
On the other hand, converting a bicycle into an electric bike requires a certain mechanical knowledge. This adds a point to an electric bike option as it comes ready to use. You can also experience some problems with batteries, pedal sensors, controllers and other significant components of a conversion kit (however, sometimes it’s also true for ready ebikes).
Electric bike conversion kits are a great alternative to ready-made electric bicycles, especially when you already own a regular bike. These kits are very precious tools to commute, travel and have a lot of fun. The newest technology provides them with incredible features to make them comfy, affordable, and easy to install and ride.
Remember, there is no universal best electric bike conversion kit that would suit everyone simultaneously. You just have to pick the right one depending on your individual needs. However, you can be sure that all the models mentioned in this article are great candidates for purchasing.
