Build to Last: The motor is made of copper, which can be wear-resistant, corrosion-resistant, high-temperature-resistant and impact-resistant to ensure long-term use.
Labor-saving Assistant: You don't need to laboriously step on the pedal any more with this product and can flexibly control the speed by gently turning the grip, which is very labor-saving and convenient.
Safe Riding: The wire and interface are well connected to ensure a low failure rate in long-term use. The conversion kit is also equipped with a powerful controller, which helps ensure the smooth operation of other components, making your entire process safer and easier.
Low Resistance: The product uses a motor with a flywheel, so when you step on the pedal and there is no power to the motor, the motor will not rotate to minimize resistance.
Satety Guard:  Lights inside the package provide you with a clear view during your ride. The electric door lock comes with two keys so that you can be free from the risk of product theft. The brake handles are very sensitive to protect your riding safety.
Complete Kit: The package includes complete accessories, allowing you to conveniently install and use it without additional purchase.
Hassle-free Cleaning: Thanks to its smooth surface and removable design, you can easily clean it with a rag (not included).
Ideal Gift: With a beautiful appearance and practical performance, it is a great surprise for your wife, mother, daughter, friend or loved one.
