BBR Tuning Motorized Bike Jackshaft Kit Item# BBR-JKSHAFT

OUR PRICE: $189.95
List Price: $297.95

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. 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.
