The ID of the channel is 3.4" wide.

NOTE: Most of the smaller engines with 52 mm clutch rotor like the Honda GX25. 

The engine should have 1.2+ HP for this drive roller. 

The engine or kill switch is NOT Included.

MADE IN THE USA.

Included in this kit:

One: 1" Drive Roller with 12mm x 1.50 male threads. CNC Machined, Heat treated and Zinc Plated.

If you want LESS top speed, more pulling power for hills and bucking the wind pick a smaller drive roller.

If you want a FASTER top speed, less pulling power on hills and bucking the wind pick a larger drive roller. 

Keep in mind the larger the drive roller you will have to assist pedal the bike up hills and high winds.

One: 54 mm Clutch Drum with 12 mm x 1.50 female threads.

One: Custom made 60" long throttle cable with the small lever & #16 mini hose clamp.

Four: 8” long Black Nylon ties to secure the throttle cable and kill switch wire to the frame.

The kill switch is NOT included. Be sure and add the type you want to the order.

Two: ¼” x ¾” x 15” long Aluminum flat bar, CNC machined and Black Anodized.

One: Alloy Skewer - Quick Release, 5mm -.80 x 161mm with channel spacers and hardware.

One: "U" Bracket with backer plate, zinc plated with hardware

Four: 6mm x 1.0 x 35 mm Hex Head Bolts 8.8 grade bolts.

One: Engine Spacer, CNC machined and made out of steel, zinc plated. This keeps water from getting into the clutch rotor, more secure mounting of the engine and used for safety.

One: 1/4" thick Aluminum Extrusion channel that is CNC machined and Anodized Black.

The channel is 4" over all width x 3.50" Inside width.

(not a bent thin piece of steel like the others that have tried to copy my product)

Two 5/8” ID x 1-3/8" OD x 7/16" wide High Speed Double Sealed Ball Bearings with retaining ring.

We use one High Speed Double Sealed Ball Bearing on each side of the Drive Roller to support it and remove all the pressure off the engine.

Rear mount kits will come with a 60" long throttle cable with the small black lever and hose clamp.

If you have a Ladies Frame bike you will need approximately 68" throttle cable.

Some folding bikes like the 20" Dahon need a 72" long throttle due to the way the frame and long up raise on the handle bars.  

This kit includes everything except the ENGINE & KILL SWITCH.
