Left Chain Drive

This electric conversion kit is designed with a left chain drive system, which means that the motor will assist in propelling the bike by directly driving the left side of the chain. By utilizing the left side of the chain, the conversion kit ensures an efficient transfer of power from the motor to the bike’s drivetrain.

The left chain drive system offers several advantages. It allows for simpler installation and maintenance compared to other drive systems. The position of the motor on the left side also helps in balancing the weight distribution of the bike, resulting in better overall stability and handling.

With the left chain drive system, you can enjoy an enhanced biking experience with the added power of the electric motor seamlessly integrated into your bike’s drivetrain.

24VTwist Kit

The 24VTwist Kit is a unique feature of this electric conversion kit. It refers to the twist throttle control mechanism that allows you to control the electric motor easily. By twisting the throttle, you can adjust the level of motor assistance according to your preference and riding conditions.

The twist throttle provides a more intuitive and responsive control over the motor. With a simple twist of your hand, you can increase or decrease the power of the motor, effectively changing the speed of your electric bike. This feature offers convenience and precision, allowing you to effortlessly adapt to different terrains and riding scenarios.

Pro-tip: Practice using the twist throttle in a safe and controlled environment to get accustomed to the different power levels. Gradually increase the assistance level as you gain confidence and experience with your electric bike.

Compatibility with Common Bikes

This electric conversion kit is specifically designed to be compatible with common bikes, making it a versatile option for riders who want to transform their existing bicycle into an electric bike. The kit can be easily installed on a variety of bike frames, allowing you to enjoy the benefits of electric assistance without the need to purchase a dedicated electric bike.

Before purchasing the kit, it is essential to ensure that your bike is compatible with the conversion kit. This includes checking the frame geometry, wheel size, and other specifications specified by the manufacturer. By confirming compatibility, you can be confident that the kit will seamlessly integrate with your bike, providing a reliable and efficient electric biking experience.

This conversion kit opens up the possibilities for riders to upgrade their current bike and enjoy the advantages of electric assistance at a fraction of the cost of purchasing a new electric bike.

Our Review and Score

Our Score: 69.0

I recently purchased the 24V36V250W Electric Conversion Kit for Common Bike Left Chain Drive and I must say, it has completely transformed my bike riding experience. I installed this kit on my old mountain bike and it has turned it into a powerful electric bike. The motor is incredibly efficient and I am able to reach higher speeds without much effort. The kit was easy to install, especially with some modifications to the motor bracket. I also appreciate the durable construction of the motor and its ability to handle heavy usage without overheating.

This conversion kit has exceeded my expectations in terms of performance and durability. I have ridden over 35 miles without any issues and the motor continues to work flawlessly. I have also made some modifications such as upgrading the controller and changing to a 36V setup, which has only improved the performance of the motor. The only downside I have experienced is that the included freewheel is of lower quality and may need to be replaced. Overall, this kit has provided me with a great ride and I highly recommend it to anyone looking to convert their regular bike into an electric one.

However, I must mention that installing and fitting this kit may require some modifications, especially if your bike has disc brakes or non-traditional geometry. It took some bending and filing to align the motor properly, but with patience and some basic mechanical skills, it can be done. The kit is great for riding in hilly areas and provides a good assist when climbing uphill. The battery life is decent, but I would recommend getting a higher voltage setup if you want more power and range. Despite the minor challenges, this kit has helped me achieve my fitness goals more easily and has made riding up hills much quicker.
