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.
This kit has the .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.
The 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.
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.

Not only is the quality of the product good, it really works better than I could have imagined. I expected a friction drive setup like this to have issues and be unreliable. Boy was I wrong! If you don't want to deal with chain driven setups than this is the next best thing. If you don't wan to turn your bike into a "motorcycle" this is perfect, using the .930" roller with the Honda GH35 engine it meshes seamlessly with the 36T chaining and my 28-14T 5 speed. I can peddle at about 15mph if I'm working hard, and that's what the cruising speed on this engine is on my setup. It effortlessly will pull you along and really help you climb hills. I use mine as a hybrid so I usually peddle along with it since I have it geared to work that way. If you aren't sure whether you want to give it a chance, just do it!
