Electric bikes are getting more popular by the day. Since they're reasonably priced and readily available, you can easily purchase them online. However, for DIY enthusiasts, nothing beats the satisfaction of successfully converting their regular bike into an e-bike on their own. If you're looking for high quality electric bike parts you've come to the right place! Purchase a-la-carte and DIY your electric bike kit today!

Our selection of electric bike parts is ideal for replacements, upgrades, or for completing a new DIY e-bike conversion project.


You'll need to purchase these parts to make a complete 250 Series Electric Bike Kit:

To enhance your ride, we also offer the Specialized Speedzone Sport. This device is a specialized trip computer designed for bikes, allowing you to check your speed, distance, and battery life. While it is not a required part to complete your e-bike conversion, you will find this device extremely useful, particularly because of its low-battery indicator.

Apart from the electric bike parts mentioned above, we also offer spokes and nipples. Our stainless steel spokes are designed to accommodate standard wheel sizes with the 250 Series electric motor. Available sizes include 205 mm for a 24-inch wheel, 229 mm for a 26-inch wheel, and 259 mm for a 700c, 29-inch wheel.
