Motorized Bike Sprockets

Super Sprockets for Motorized Bicycles feature our exclusive new Quad Mounting Pattern for use with ALL known bicycle engine kits. (NOTE: The pictures of the sprockets on this web page are OLDER and only have 2 patterns drilled BUT our NEW sprockets ALL have the Quad Mounting Pattern). (NOTE : We also make Super Sprockets  for Grubee Heavy Duty Freewheel Hubs,  Grubee Heavy Duty NON-Freewheel Hubs,  Manic Mechanic Adapters,  Sick Bike Parts Shift Kits and others….(When ordering Super Sprockets for these applications be sure to mention it in the “notes to seller” section on your Pay Pal Payment or you will receive our standard Super Sprocket for motorized bike use).

Super Sprockets are drilled to accept the Heavy Duty 9 Hole mount (8 MM bolts), Standard 9 Hole mount (6 mm bolts on a large bolt circle diameter), Light Duty 9 hole mount (smaller bolt circle with 6 MM bolt holes) AND come drilled for direct to disc brake hub mounting.

The disc brake mounting option is the most accurate way to hold a sprocket true (mounts the sprocket in place of the brake disc on a disc brake hub) but may cause chain line issues on some bikes or may require redishing and/or spacing the rear the rear wheel/axle….Not all frames are affected but some are…..

If you are affected AND / OR want to use a rear disc brake, we now offer our  Top Hat Sprocket Adapter (NOTE : If ordering Super Sprockets for use with our Top Hat Sprocket Adapter be sure to indicate that in the “notes to seller section” in your Pay Pal payment so we can enlarge the center bore for you).

The Top Hat Sprocket Adapter precision mounts the rear sprocket onto any ISO standard 6 bolt disc brake hub AND helps to put the sprocket closer to the spokes to help ensure a perfect chain line!

The adapter can be used WITH OR WITHOUT a disc brake system or disc rotor if you just want to take advantage of its superior mounting method OR want to retain the use of the rear disc brake.

ZERO run out or wobble means longer component life and less chance for your chain to jump off at speed because of the imprecise factory rubber 9 hole mounts. Superior mounting also means faster speeds with less vibration!

The Top Hat Sprocket adapter is made of the same great aerospace grade 7075 T651 aluminum we make our Super Sprockets from…Super Strong and lightweight (2.1 ounces for our 1/8″ offset model for use with standard sprockets, or 2.8 ounces for our 1/4″ offset model for use with our Race Series Sprockets NOTE: The combination of 1/4″ offset Top Hat AND a Race Series sprocket will weigh LESS overall than the 1/8″ offset Top Hat and standard sprocket).

You can mix and match sprockets (Race Series (no off set) OR Standard Super Sprockets (approximately 1/8 to 3/16 offset) AND Top Hat Adapters (1/8″ offset OR 1/4″ offset ) to help achieve a perfect chain line. NOTE: because of the literally hundreds and hundreds of possible hub, wheel, and frame combinations out there, final or additional spacing can be also done by using washers if needed but generally this is not required).

To save you money, you can reuse the factory nuts and 8mm bolts but they will need to be cut down since they are far too long….An installation video is available on You Tube at :

Yes, you can even reuse your stock sprocket if you’d like (NOTE: if you do want to reuse your stock sprocket, you will need to enlarge the center hole to about 2.1 inches (to clear the disc hub mount area) and you will need to make sure your sprocket has the HD 9 Hole Pattern (8 MM bolts)…If not you can drill as needed)….

If you order your Super Sprockets from for use with the Top Hat Sprocket Adapter please be sure to mention that it is for use with the Top Hat and we will machine everything for you for a simple bolt on performance increase.

The Top Hat Sprocket adapter is available for $37.50 (Please specify either 1/8″ offset or 1/4″ offset…if no mention is made, we will send out the 1/8″ offset model). Shipping prices are listed below.

Our standard sprockets have a built in bevel to allow for better chain line alignment…our race series have the bevel machined out to reduce weight even further (NOTE: if you currently run your sprocket with the bevel out (sprocket teeth closest to the spokes which is most applications) you can use the Race Series Super Sprockets without any problems. The weight of our CNC’d Super Sprocket Race Edition is approximately 2.7 ounces in 36T The weight of our standard CNC’d 36 T sprocket is approximately 5.25 ounces VS. 11.8 ounces for a steel gear….Less weight means Faster acceleration and Better braking….NOTE: Race series sprockets have the offset machined off to save even more weight without sacrificing strength..

Each Super Sprocket has the tooth count stamped on it for easy identification.

Finally, Super Sprockets are available in 9 Anodized colors ( 8 colors: Hot Pink, Brazen Orange, Midas Gold, Sunshine Yellow, Sky Blue, Lime green, Midnight Black, Super Silver) to add a little bling bling to your ride for just $7.50 more per sprocket.

Hard Coat is also available (bronze in color) for just $7.50 extra per sprocket (Hard Coat adds approximatley 35% more durability and life to an already incredibly long lasting sprocket).

These are the secret weapons that will allow you to win races against your friends!

They will also make for a more enjoyable high speed cruise since your engine will not be screaming for no reason (better mileage and less wear and tear on the engine) ….FYI – Each tooth you lose off the 44T sprocket gains you approximately 1 MPH on the top end….So If you are running a 35T sprocket and your buddy is running a 36T….You will pass him and there’s nothing he can do about it…Great fun!

At no additional charge we can (just let us know): Enlarge the center hole to 1.75″ to better work on coaster brake hubs or other hubs requiring additional spacing.

We also make Super Sprockets  for Grubee Heavy Duty Freewheel Hubs,  Grubee Heavy Duty NON-Freewheel Hubs,  Manic Mechanic Adapters,  Sick Bike Parts Shift Kits and others….(When ordering be sure to put the application in the “notes to seller” section on your Pay Pal Payment or you will receive our standard Super Sprocket for motorized bike use).
