Electric Conversion Kit for Bicycle Derailleur

The 350W and 450W motor kits are now available for purchase. These kits are designed to provide an effortless biking experience, allowing users to ride their bikes with greater ease. Each kit includes the following components:

1. 1x 250W brush motor (with freewheel sprocket)
2. 1x Chain
3. 1x Customized sprocket & components
4. 1x Motor controller (with fuse wire)
5. 1x Mounting plate + bolts
6. 1x Throttle handle/Thumb throttle
7. Some connectors

Please note that the kits do not include the battery or battery charger, which must be purchased separately.

Before placing your order, there are a few important considerations:

1. This kit is compatible with bikes that use a V-brake on the rear wheel. If your bike uses a disc brake or coaster brake, this kit will not be compatible, and you should choose a different kit.
2. The motor bracket may not fit your bike frame, and you may need to modify the bracket yourself. If you are unsure how to do this, please send us a picture of your bike, and we can provide suggestions.
3. This kit is designed to make riding a bike easier, not to make it faster. A 26-inch bike equipped with this kit can reach speeds of up to 20 km/h. We recommend that you pedal along with the motor power to extend the battery life.
4. The primary difference between the 24V and 36V kits is the working current. If you want to ride for longer distances, we recommend the 36V kit.
5. The kit does not include a battery, so you will need to purchase one separately. Both lead-acid and lithium-ion batteries are compatible, and we suggest a 24V 15Ah or 36V 12Ah battery.
6. The motor controller comes with one fuse wire and three fuses. If a fuse burns out, please take note of what caused it and try to avoid the issue in the future. If you need further assistance, feel free to contact us.
7. This item offers two throttle options: a twist-type "key throttle" and a thumb-type "thumb throttle." Please select the one that best suits your preferences.

The installation process is straightforward, and a video tutorial is available on our YouTube channel (https://youtu.be/6nIsvJon57E) to guide you through the process.

The motor in these kits is a UNITE brand motor, known for its reliability and performance. Whether you choose the 350W or 450W kit, you can expect a smooth and enjoyable biking experience.
