NOTE: #1. HD Axle Wheel with 5-hole Freewheel Hub is for rope pull start 4 stroke engines only and use 5-hole sprockets only:   

However, if you have our Gru-Bee 4G or 5G Belt Transmission that has a driven belt pulley with Freewheel then you can use our 2 stroke HD axle wheel with solid hub.   If you have no freewheel in your 4-stroke engine transmission, then partner this is the wheel for you!    

 NOTE:  A Freewheel Axle Hub will not work with pedal start 2 stroke engines.   The Freewheel is designed to be used with then torque of 49 to 53cc 4 stroke HuaSheng engines.

For 2 stroke engines you must use solid 6-hole hub HD axle wheel.   See the solid hub wheel at our SkyHawk 2 cycle section. 

Why buy 2 cast aluminum wheels with cheap bearings when one HD Axle wheel matches most Vee Frame bike's existing front spoked wheel and can do so much more 

Keeps the original look of vintage bikes. 

HD Axle Wheels avoid the troublesome and undesirable method of clamping a 9-hole chain sprocket to wheel spokes.  Clamping to spokes was never a good idea!   It's a poor man's substitute. 

  • HD Axle 26" wheel with 12 ga. spokes. 

  • Suitable for 1.95 to 2.25 tires.

  • Wheel Rim has spoke eyelets found only in expensive rims. 

  • For Safety and Longevity HD Axles have (2) double row sealed #5200 ball bearings, and that means you are setting on a total of 4 rows of ball bearings for long life enhancement.

  • Works with both Disc Brake and or a Caliper Vee-Brake.   2 ways!     Yes, can even install both brakes for super stopping power back up.

  • Includes a 5 Hole Freewheel 36-1 Left hand thread sprocket hub and 3mm tk spacer lock ring.    

  • Includes rubber wheel rim band.

  • Right side of the HD axle has 1.375-24 English threads for screw on 14T to 20T pedal sprockets. 

  • Right side Pedal sprocket is not included.

  • Review the pictures here in for installation ideas. 

  • NOTE:  Freewheel requires frequent lubrication with light weight oil.    Apply oil around circle crack with wheel lying flat.

  •  Left side Chain Sprocket is not included due to so many different diameters.  Order your engine drive sprocket on same order with wheel to be include in same shipment.

  • Hardware is not included with the sprocket purchase.    

  •  HEADS UP Guidance: The motorized bike builder is the prime contractor and accepts all liability.  


    • 2-stroke engines require a permanent affixed Sprocket Flanged Hub but 4-stroke rope pull start engines do not when using a Freewheel Sprocket Hub. 

    • The disc brake hub must be used in all cases as it serves as a jam nut for the Sprocket Hub.

    • Normally, install the drive sprocket on the outboard side of the Freewheel Sprocket Hub.  However, if using disc brakes, you may have to use the back side to enable proper caliper fit.  TBD.  Failure to install DBs is not a warrantable situation.

    • The ¼” wide spacer ring can be located on the inboard or outboard side of the hub depending on the required application. Tighten lock rings by tapping in notches with hammer & punch.

    • Decide if you want the sprocket teeth inboard convex or outboard concave. The wheel is shipped with M6 bolts loose and the sprocket teeth outward for the most chain / tire clearance.  Use 242 Blue Loctite.   

    • Before installing the Freewheel sprocket measure where the drive chain needs to be and also if using Disc Brakes.

    • NOTE: Failure to install the Freewheel Sprocket hub correctly can damage your axle.   

    • A spanner wrench is needed to remove the freewheel sprocket once installed in the CW Left Hand direction.

    • Do not install the Freewheel Sprocket Hub loosely, it must be jammed  tight against either the spacer ring or the HD Axle hub shoulder and the disc brake hub serving as a final jam nut.

    • Good luck in your build and may God speed you safely.
