Most Powerful Electric Bike Conversion Kits

By Chris Wilson

Power requirements like High wattage, Amp hour and Volt rating is what you require to ride over rough terrains and long distances. For the utmost effortless journey, you need to install a powerful e-bike conversion kit. Below are the top 4 most powerful e-bike kits available in the market. A detailed review of each option is here.

The questions answered below will help you select a conversion kit that is the most appropriate according to your budget and needs.

How Much Power Do You Need?

The amount of power required by your e-bike is dependent on your weight, the purpose you will be using the e-bike for, the terrain, how fast you want to ride and the weather conditions. A heavier individual wanting to climb up a steep terrain would require more force than required by a skinny person to ride up a hill.

For a short commute (i.e., 15 miles) the recommended motor wattage would be 500W, however if you enjoy higher speeds a 1000w -1500w motor would be ideal since they are more powerful and bring a much better hill climbing experience.

Does the Battery Influence the Power of Your E-Bike Conversion Kit?

The power output of your e-bike conversion kit depends on its two components, the controller and the motor. The controller is responsible for supplying the electric energy to the e-bikes motor while the motor converts this energy to help the e-bike accelerate.

Most E-bike conversion kits include a battery that supplies energy to the electric motor (included in the kit) to produce power. It is important to keep in mind that a larger battery would have no effect on the motor’s power output. The battery should be able to provide enough current to keep the motor working, any additional increase in its capacity would not increase the power output of the motor.

Factors That Impact the Power of an E-Bike Kit

In order to determine how fast or powerful your e-bike conversion kit is, it is important to understand the energy measurements that apply to the motor and battery in the kit.

Watt is a unit of power that measures the instantaneous power input or output of your e-bikes motor which significantly affects your e-bike’s performance. 

The two-watt ratings to consider before buying an e-bike conversion kit are: The continuous watt rating which is the amount of continuous energy consumed by the motor and the peak watt rating which describes the quantity of energy managed by the motor for a short time period. 

For a better idea of the maximum power of your motor multiply the battery voltage with continuous amperage from the motor to get the watt hours.

Amps(A) x Volts(V) = Watts(W).

In the United States a 750-watt motor with a speed of 20mph is the legal limit so unless you want to use the e-bike off the road or on mountainous terrain avoid going for higher watt ratings.


Volts determine the horsepower. They measure the amount of energy pushed from the battery to the motor and the responsiveness of the e-bike. High volts can get you increased RPM from the motor which results in better performance, endurance and speed.

Amp Hours

Amp hours define the amount of power an e-bike’s battery can hold. A battery with a high amp hour rating is able to hold more energy and allow the e-bike to go for long distances.

Higher voltage and amp hours will make your e-bike accelerate faster, climb up steep hills and travel over long distances effortlessly. 

Other Important Features to Consider Before Buying an E-Bike Conversion Kit

  • Motor: the power of your kit is determined by its motor. The higher the watts and the rpm rating the better the speed and performance of your bike.
  • Durability: choose a kit that is reliable and gives you the value for money.
  • Power-Assist vs. Full-Power: select power assisted e-bike kits for long rides on one charge or full powered motors for shorter quick rides.
  • Speed: look for a kit with a good amount of control and torque with a speed throttle that can regulate the speed of your conversion kit. Along with the volts and amp hours also consider the weight of the kit and the rider since heavy weights slow down the e-bike.
  • Battery: opt for a higher voltage battery to increase the speed and power of your bike. For casual usage a battery under 24v is ideal however, if you intend to use the bike on a rough terrain then choose a battery around 48V. Also keep in mind that the capacity of the battery which determines the range of your bicycle.

It is important to note that motors with similar watt ratings from different companies may have a difference in their power levels. 

Read and understand the above-mentioned information and data to finalize an e bike conversion kit that suits your power requirements.

Electric Bike Conversion Kit

1. HALLOMOTOR Electric Bicycle Conversion Kits

The HalloMotor rear wheel kit is a high-quality option available at a reasonable price and is ideal for individuals looking for a powerful e-bike kit. However, the absence of a battery in the package is off-putting. It has a highly efficient 85% brushless gearless hub motor which provides fast acceleration and speeds up to 55km/hr. The power delivered is smooth with excellent support on uneven and flat terrains. 

The kit includes a threaded motorized wheel, a Controller, a bag for the controller, left and right brake levers, Twist Speed Throttle with an Electric Key Lock 2ea, PAS (Pedelec Sensor), Battery connecting cables and a LCD display. 

What I evaluated about this kit is the impressive performance of its 48v 1000-watt motor delivering an extraordinary Speed of 600 RPM along with its high-quality components that are also relatively easier to install.

You can now effortlessly convert your bicycle into a motorized one by using this kit. It is extremely easy to install and can fit 99.99% of the bikes available in the market. The only downside however, is the moderately noisy motor and the 48v battery which makes the e-bike somewhat heavy.

The Brushless Mid Drive 48V 1000W motor has demonstrated to deliver an efficiency of 85% and works extremely well in assisting mountain climbs.

To aid your convenience the kit also includes a Speed  Sensor, a thumb throttle, brake levers or brake sensor, an LCD, and a chain wheel with a free head or tail light.

Even the best kits certainly have some disadvantages. This power pack kit lacks essentials like tires and battery, that is therefore more expensive than the kit itself. The main drawback is the heavy weight of this kit. Poor cable management and over thickened rubbers is another dispute about these kits.

These kits come with an already attached hub motor and a double walled aluminum rim making them easy to install.. The powerful 1.45kW brushless hub motor and its controller has a high build quality which will make ascending and descending a hill effortless.

The waterproof kit includes a thumb or twist throttle, PAS, a freewheel, a torque arm, a tube liner and two brake levers. The upgraded display is extremely functional and records the speed, distance traveled, battery level and the wattage of your motor.

What made this kit unique for me is the option of freewheeling and cruise control which allowed instant switching between regular and power assisted pedaling.

4. BAFANG Mid Motor Ebike Conversion Kit

Although a comparatively pricier option the Bafang BBS03B is the cream of the crop.The kit is a successor to the previously mentioned BBS02B and comes with the necessary video instructions for installation. However, no technical details on its working mechanism are provided.

It comprises a durable 1000w brushless motor that reaches a peak wattage of 1500w making gliding across flat land effortless and is compatible with a variety of bike types like road, fat and mountain bikes. The battery included has a large capacity and longer life providing a better mileage.
