Description
Designed to work with your existing gears and derailer on your bike, this Jackshaft kit will install onto any 2 strokes motorized bicycle engine kit and allow you to shift gears using your bicycle's drivetrain. No longer will you have a separate sprocket just for your engine kit. This kit is perfect for those looking to get the most speed from their engine without sacrificing low-end acceleration that crucial for taking off from dead stops. Recommended for only advanced users as this kit does not include specific instructions and can allow your engine kit to do dangerously high speeds.
Use your existing gears/dérailleur to maximize the performance and top speed of your motorized bike. This kit bolts onto your bike frame and motor and connects directly to the bikes gear system rather than using a separate sprocket.
Warning: Installation is not for the faint of heart. This kit will allow your bike and bike engine kit to do dangerously high speeds! Install at your own risk.
Recommended for advanced users. The kit does not come with instructions.
*Note: These JackShaft kits have been updated to include thinner, non-dished sprockets for better shifting, a chrome-colored sprocket guard for a better look over the old clear plastic one, and does not include a rear wheel bicycle hub.
