It would be nice to be able to just browse the web site but I contacted the dealer in California, he has been good about answering questions and has even sent pictures of his set up. Looks like they'll run about $260
This is the most useful info I have found...
The EZM Q-Matic is completely different from all other drive systems. First it is American made; secondly the heart of the system is based around the world's best clutch.
We researched the majority of the current drive systems and found them based on poor engineering and poor quality control. Many are based around clutches designed for other uses such as roto tillers, edgers, weed eaters, etc. Sadly the clutch needed for a motorbike has different requirements. The clutch must engage smoothly, engage completely, and have the correct stall speed. Further research lead us to find a clutch actually designed to move a motor vehicle and be of such quality to be durable. It seems most companies don't have a clue of the demands of a motorbike clutch. This research lead us straight to MaxTorque an American company that designed the centrifugal clutch used on commercial go cart tracks. If their clutch could hold up under the severe conditions of go-cart rental, it surely could work on a motorbike.
While it is true the clutch is costly, using specially designed parts, it is also "bullet Proof" and won't strand anyone with broken clutch housings, loose shoes, excessive wear, and more importantly it won't damage the crankshaft of the motor [because it isn't installed on the motor]. We worked closely with MaxTorque to modify and make a "special" clutch for our system and still use the basic proven design. The MaxTorque clutch designed for the Q-Matic isn't a standard production unit, but they quickly helped us with special custom parts for our system to make it work 100% correct.
The clutch is approx 4" across and uses 6 shoes [not 2 or 3], the replacement parts [if ever needed] would be easy to install and are reasonably priced. We even designed the Q-Matic to accept special "Racing" clutches from MaxTorque if one wanted to move in that direction.
The Warranty is one year on the clutch and the drive can be rotated to use as a rack mount if desired.
Because of the design of many motors used as motorbike power plants, attaching a clutch directly to the crankshaft can lead to serious problems. Adding the weight and stress of a clutch can damage the crankcase, crankshaft, crankshaft bearing [some motors don't even use bearings on the output side of the crankshaft] and worst of all the width of the motor ends up so wide it causes many other issues.
Another major advantage to the Q-Matic is the high "pass thru rate". Many current drive systems consume a large amount of power, and when starting with 2 HP you can't afford to give up much. As an example think about turning gears in heavy grease [to quite down the excessive noise], it is similar to rowing a boat in the mud. Also consider the large amount of power needed to run a CVT drive [up to 30% loss]. How about running a clutch in grease or oil with 2 or 3 pivot shoes and expect it to completely lock.
The Q-Matic is slim, durable, silent, American made, and transfers almost all the power to the wheel. The Q-Matic can use completely different drive ratios to increase gas mileage, run the motor at a lower RPM to increase the motor life as compared to other companies. The Q-Matic drive is designed to use the peak torque of the motor, not WOT all the time like many current offerings. The Q-Matic is tuned to take advantage of torque, and can easily be altered to provide different ratios for hills & heavier riders often for less than $15.00.
