( 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.
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 assit pedal the bike up hills and high winds.
We Do NOT recommend the Honda GX50 with a .930" drive roller is good for riders over 250 lbs and / or if you have lots of hills with a top speed of about 22 mph. Mostly used with engines 1.10 HP and Higher.
We Do NOT recommend the Honda GX50 with a 1" drive roller is good for riders up to 200 lbs and some hills top speed is about 25 - 27 mph. Mostly used with engines 1.10 HP and Higher.
The 1-1/8" drive roller is the standard and most common size for riders up to 280 lbs with mostly flat ground that want a fast top speed about 30 mph.
Mostly used with engines 1.60 HP and Higher.
The 1.34" drive roller and for riders 150 lbs or less and mostly flat ground 37+ mph.
