Electric bikes are the delight of lovers of cycling. It makes commuting easy and is very safe for the environment. However, getting an ebike may be expensive, especially if you want a robust and durable ebike. With the help of conversion kits, you can convert your regular bicycle to an ebike.

In recent times, there has been a rise in the demand for conversion kits. As a result, several manufacturers are fast saturating the conversion kits market. Thus, choosing what conversion kit fits you best is difficult, especially when working with a budget.

Choosing an excellent conversion kit on a budget could be tedious. However, we have compiled a list of the cheapest electric bike kit you could find out there. That way, it would be easier to know the pros and cons of each of these conversion kits. Before diving into that, let us consider the types of ebike conversion kits.

Essential Factors To Consider When Fitting Your Kit

Many conversion kits available might make it confusing to know what option to choose. This might be worse if you are a newbie because the specifications look the same. When selecting a conversion kit, you need to consider some essential factors. These factors are:

1. The Motor Type The Conversion Kit Uses

Ebikes commonly use three motor types. They are the mid-hub motors, the rear hub motor and the front hub motor.

You cannot outrightly tag them as good or bad because they have varied advantages and disadvantages. The motor type that suits you best depends on the terrain you are riding on and the frequency of use of your ebike.

The front and rear hub motors are easier to fit and maintain than the Mid-drive motors. They do not strain the system of your ebike and would make it easier for you to get around faster. Front and rear hub motors function excellently for regular commutes and daily trips.

Due to the positioning of these motors, they don't give your bike much balance like the mid-drive motors. Also, choosing either of these systems would restrict the type of tires, rims and cassettes you can use for your bike.

On the other hand, Mid-drive motors are best used for off-road commuting. While they work well for regular terrains, the advantage of this motor type is best experienced in rugged landscapes. They are positioned in the midsection of your bike. Hence, giving your bike stability and balance. Additionally, using the mid-drive motor means using a wider range of tires, rims and ebike parts.

2. The Power Rating Of The Ebike Motor

How much ebike power you would need is dependent on the average length of trips you tend to make with your electric bike. You could liken the power rating of an ebike motor to the horsepower of a car. The power rating of the ebike is usually measured in watts and Newton meters of torque.

The higher the wattage of the ebike, the longer the motor can sustain the ebike without overheating. If you only commute short distances at low speeds, an average or minimal power rating will be perfect for your needs. However, heavy riders interested in speed should look out for ebike motors with high power ratings.

As a regular rider who is not so bothered about speed, a 250-watt ebike with 4o Nm is fine. If you are a heavy rider, you should aim for a higher power rating of about 750 watts. If you tend to ride quickly, coupling the 750 watts with a minimum of 80 Nm will cater well for your needs.

3. Battery

The battery of the electric bike kit is an essential factor you need to look out for. The effectiveness of your bike, speed and largest coverable distance depend significantly on the battery of your conversion kit.

Some cheap conversion ebike kits do not come with a battery. However, several options come with a battery. You need to take out time to choose a battery that would suit your commuting needs and the type of ebike motor your conversion kit uses.

More powerful ebike motors tend to drain the ebike battery faster. Given this, opting for a powerful conversion kit motor also implies the need to invest in a heavy capacity battery. While making this choice, you need to factor in the strength of your bicycle frame. Fitting a battery heavier than the ebike frame's strength could destroy the bike.

Even if you are not a technician, you could easily project your ebike battery's maximum duration. To estimate the maximum hours the bike will serve, multiply the amp hours of your battery by its voltage.

For example, if the battery has a voltage of 60 V and a 10 A controller, the multiplication of both figures gives you 600 Watt-hours. This implies that your battery can give you 600 watts continuously for one hour. If you move at 1200 Watts, your battery will last only 30 minutes.

4. The Sensor Type

There are two main types of sensors: the cadence sensor and the torque sensor. The torque sensors give a more natural feel than the cadence sensors. The power delivery by the torque sensor depends on the force of rotation applied to the crankset. Consequently, they do not deliver more power or less than is required per time. Due to this mode of operation, torque sensors could help to extend the battery life of your ebike.

Cadence sensors supply a proportional amount of power based on how fast the pedals move. The cadence sensor is located at the crankset, enabling it to detect the speed of the pedals. Based on the detected motion, it supplies assistance to the rider. Compared to torque sensors, cadence sensors are cheaper and easier to fix. However, its power delivery is often jerky, making the assistance supplied feel unnatural.

5. Compatibility Of The EBike Kit With Your Bicycle

Before purchasing an ebike kit, you should ensure it is compatible with your bicycle. For Mid-drive motors, ensure the kit is compatible with the cassette of your bicycle and its bottom bracket diameter. Also, watch out for the bicycle's frame to ensure that it can comfortably accommodate the weight of the motor.

If you opt for rear and front hub motors, make sure they are compatible with your bicycle's brakes. Additionally, the dropout of your bicycle should be wide enough to accommodate the motor perfectly.

6. Legality

Different states have different laws. Before fitting a cheap ebike kit into your bicycle, ensure the speed limit is acceptable by your state. Additionally, find out if you need a license to operate an ebike in your state. To be safe, it is best to check the legal regulations before purchasing and installing a kit.

Frequently Asked Questions
Is the cheapest electric bike kit worth my money?

The fact that the kit is cheap does not make it non-functional or inferior. The price of a conversion kit is often the cumulation of several factors. These factors could include "brand name", motor power, functionalities and even the essentials that come with the kit.

Can I install the cheapest ebike conversion kit on my carbon fibre frames bike?

It is possible to fix a conversion kit o your carbon fibre bicycle. However, such a decision is not advisable. Carbon fibre frames were not designed to accommodate the extra weight, stress and strain of installing an ebike motor. Subjecting them to such pressure could be dangerous for the bike and put you at risk of an accident. It is best to only install conversion kits on bicycles with steel or alloy frame.

What tools do I need to fix the cheapest electric bike conversion kit?

To fit your ebike conversion kit, you would need the ebike conversion kit, a crank arm, and a bike tool. Additionally, you would need wrenches and a screwdriver.

Are Electric Bike Conversion Kits Difficult To Install?

The difficulty of installing the kit is dependent on factors like the kind of kit and your prowess with the installation tools. Converting your bicycle to an ebike may not be stressful if you are familiar with handling the required tools.

Should I get a conversion kit or buy a new ebike?

The answer to this question is not generic. Before making a choice, it is best to count the cost and weigh your options. A new electric bike would cost more than fitting a conversion kit in your current bike. Additionally, the functionalities of ebikes vary, and this affects their prices. Hence, the price of a standard ebike you love may exceed your budget.

Can I use Lead Acid batteries?

Yes, you can. Sealed lead acid batteries are cheaper than their Lithium counterparts. They are heavier as well, but they would power the kit effectively.
