#2 HD AXLE 26" WHEEL made for 150mm dropout multi-speed bikes and 2-stroke pedal start engines.

HD AXLE WHEELS are shipped via UPS so cannot be delivered to a USPS PO Box #.

An all-steel solid axle hub with M6 bolts means it's much stronger than those made of cast aluminum that use small M5 screws holding a disc brake hole pattern sprocket. See last picture.

See 25 attached pictures and read all the descriptions here in to gain full HD AXLE understanding. Follow the instruction sheet that is included with the wheel.

This 26" HD AXLE #2 wheel is made with 12 ga. spokes for alignment with 150mm to 155mm wide multi-speed bike frame dropouts.

This Multi-Speed wheel is Not suitable for a narrow single speed bike frame. ( See our single speed wheel add. )

This wheel can be used with all pedal start 2 stroke mid-frame bike engines such as our SkyHawk Gt5A-Es as well as with 4 stroke engines as long as the engine's transmission has a freewheel included such as is found in our 4G and 5G T-belt drive 4 stroke transmissions.

(Order extra cost 6-hole Chain sprocket separately and we will install it for you. )

We have 6 hole, 36T to 56T sprockets available. We are sold out of 48T.

NOTE: This wheel is the same as the single speed wheel except the rim is spaced more inward to be in the center of a 150mm to 155mm drop out.

HD Axle Wheels can work with Disc Brakes and can also work with Caliper Vee-Brakes due to having a CNC cut flat rim designed for Vee Cal Brakes=2 ways!

#2 HD axle wheels come with a steel 6 Hole CCW 36-1 screw on chain sprocket flanged hub and 1/4" spacer lock ring.

NOTE: (6) M6 10.9 grade bolts and flanged nuts are included if a sprocket is ordered the same time as the Wheel.

#1 HD axle wheels with a Freewheel Sprocket Hub are found in the 4 cycle engine section. DO NOT ORDER A #1 HD AXLE WHEEL FOR A 2 STROKE ENGINE APPLICATION BECAUSE A FREEWHEEL HUB will not allow pedal engine starting

NOTE: CCW Sprocket Hub threads are required so the sprocket hub does not unscrew when under engine pulling power.

WARNING: As mighty and as strong as it is Failure to follow good engineering installation process can damage the HD Axle. To ensure the sprocket hub does not ever spin off during deceleration and pedal starting be sure to use a generous amount of LocTite 271 on the 36-1 CCW threads and it is a good idea to apply a wide bead of J/B Weld around the back side of the sprocket hub and lock ring.

3 Do Nots:

#1. Do Not install the 6-hole Chain Sprocket on the inboard side of the sprocket hub flange.

#2. Do not use 271 Red Loctite on the 35-1 Disc Brake Hub. Blue 243 is OK.

#3. Do not use Red 271 on any threads except where the Sprocket Flanged Hub will set on the HD Axle.

Installation Sequence Guidance ;

NOTE: the 1/4" tk. spacer ring can be installed inboard or outboard depending on Sprocket Flanged Hub direction needed for chain alignment and any disc brake requirements. Sequence below is for inboard lock ring placement as shown in third picture diagram and also as received. Due to many unknown varibles the installer is the final judge and accepts primary contracter libility for safe and sound installation.

#1A. Jam the inboard spacer ring tight against the HD Axle shoulder.

#2B. Install your chosen 6 hole sprocket on outboard side of Flanged Hub. Decide if sprocket teeth should be inward or teeth outward for chain clearance. Use Blue 242 Loctite on the (6) M6 screws and torque as required.

#3C. Test install sprocket and Flanged Hub on loosely to check position and chain clearance. Remove and make any needed corrections.

Remember > Measure twice and saw once. Failure to install is not warrantable.

#4D. If everything is decided then apply a little Red 271 LocTite around the axle threads where the Sprocket Flanged hub will set in it's final resting place. This is do or die time!

#5E. Spin the Sprocket and Hub in CCW direction jammed tightly onto the 1/4" inboard spacer ring and resting on top of the applied 271 LT.

#6F. Use # 2.5mm Allen wrench to tighten the 3 set screws down deep into axle threads to create a permanent Sprocket Hub installation.. Once locked down the Sprocket Flanged Hub need never be removed again.

#7G. Install the 35-1 Disc Brake Hub jammed tightly onto the sprocket hub. Do not leave off even though a disc brake is not to be used. Sprocket Hub Jammed 3 sides makes for a mean "mamajama"......

#8H. Install Wheel in frame and install drive chains.

#9J. If to be used, installed disc brake rotor and calipers. Make sure Rotor diameter and Drive sprockets give the necessary clearance for calipers.

#10K. Stand back and admire your work for 24 hrs. before riding to allow Loctite to set.

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

NOT ALL BIKE FRAMES HAVE CHAIN STAYS SUITABLE FOR MOTORIZING.
2-stroke engines require a permanent affixed Sprocket Flanged Hub. 4-stroke engines do not.
The disc brake hub must be used in all cases as it serves as a jam nut for the Sprocket Hub.
Be sure to install the drive sprocket on the outboard side of the sprocket hub flange or it cannot be removed in the future if installed for 2-stroke. 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.
NOTE: Failure to install the sprocket hub correctly can damage your axle when a 2-stroke engine clutch lever is released during pedal starting which creates a chain push back CW rotational force.
2-stroke: When you have finalized all fit details then and only then do you install Red Loctite 271 on the HD axle threads where the sprocket hub is to be positioned. Do not apply Red 271 anywhere else.
2-stroke & 4-stroke: Do not install the Sprocket Hub loosely, it must be jammed extra tight against either the spacer ring or the HD Axle hub shoulder with the disc brake hub serving as a final jam nut.
2-stroke: Use a 5mm Hex Allen Wrench to turn the (3) M5 pointed set screws securely down deep into the HD axle threads. Once the (3) M5 set screws are locked down, the Sprocket Hub set in Red Loctite and the Disc Brake Hub Jammed the Sprocket Hub then becomes permanently installed.
Good luck in your build and may God speed you safely.
