EZM information on the Q-Matic

[Quenton Guenther]

Just a few quick comments on the production Q-Matic drive system.

The heart of the Q-Matic drive is the MaxTorque automatic clutch.

The MaxTorque clutch is custom engineered to work inside the Q-Matic drive. Unlike other drive sytems, the MaxTorque clutch is supported by very large hi-speed bearings on BOTH ends, not just one side or center support.

The MaxTorque clutch is of course AMERICAN made and a similar version has connected the motor power to the wheels of go-carts across America for almost 40 years. If it can withstand the brutal go-cart rental market it can certainly work on modern day motorbikes.

The MaxTorque clutch supplied to EZM is a special version [costs more] and is not the same unit often advertized on several internet sites.

The Q-Matic drive can be custom tuned for low end torque, or more top end, and the EZM version of the MaxTorque clutch can also be tuned for various idle & top end RPMs.

The Q-Matic will work on low idle & low RPM motors [HF, B&S, Honda, etc]as well as High idle & high RPM motors [HS 142 & Honda GHX].

The Q-Matic can be ordered with custom ratios.

The Q-Matic isn't a CVT drive, or a multispeed system.

The Q-Matic is very light, considering the very heavy duty MaxTorque clutch, and weighs approx. 6.5 pounds. The Q-Matic is only slightly wider than 2" [2 1/16"], and can be slimed to under 2" by altering the belt cover.

The Q-Matic has 4 hi-speed bearings, 2 to support the clutch system and 2 in the idler tension system.

The Q-Matic uses special light weight aluminum alloy [expensive] and will not crack, distort, flex, or tarnish.

The primary is belt driven, and will soon use a custom version, however "off the shelve" belts will work. The secondary is chain, but can be converted to rear belt drive if needed [requires special machine shop modifications].

The clutch isn't mounted on the motor crankshaft, and therefore it doesn't slow down the motors ability to rev as quickly.

The Q-Matic has thousands and thousands of actual test miles logged prior to release.

The Q-Matic belt guard covers all the moving parts in the primary to protect riders & riders clothing [no pants leg connected to spinning parts].

We ship Q-Matics daily across America & Canada. Q-Matic are available via Authorized dealers.

Hope this information is helpful,

Quenton, A friend of mine says he's stopping by to buy a kit this week.

Hi guys, I've got a customer currently building a Silent Power EZM right now, this is his first MB, and he is progressing nicely from what I hear, tho I have no pics of his build. I do, however, have something cooking here at my place.

A customer brought me an old Schwinn frame and fork, and wants it to be a complete EZM Q-Matic when I am done. This I can shoot pics of. I have already added new wheels, tires, springer, and fenders. I am now waiting for the shipment of drives and parts from East Coast, and I will continue the build with a new build thread.

I also have a Grube 4-stroke in for repair/updating to be a better running bike than it is, and a partially dis-assembled 2-stroke on a Moon Dog. Such a shame I do not have people here to do comparison rides?

Maybe someone can tell me why so many people pretend that the EZM is NOT available to the public? I sold one to a friend/customer in Chico, one to Auburn, and one to Fairfield, and I am NOT the most successful dealer on the list here New Page 1 the owners I mentioned are in addition to the continuing work I do with dealers and prospective dealers across the US and up into Canada.

Hi Mike,

I know you just started on the build, but do you have time to take a few pictures along the way. I for one would love to see the before and after pictures.

Is this the build with the vintage Schwinn frame or a different one?

Have fun,

Hi Quenton -

The secondary drive belt.... I like this idea. Your concept sounds like it requires mating a V-belt pulley to the commonly-available through-the-spokes mount by drilling the mounting holes and cutting out the center...) I know Gates V-belts can be obtained in really long lengths. I would like someday to extend my rear wheel backward by 12 inches or so. So my desired final length would be (length of standard 415 chain plus 24 inches). I could modify my own pulley from a retailer, but if someone with a machine shop can modify a pulley for me, I'd rather purchase a prepared pulley. I may work on this during the next few months.....

HI Mike, well the rear sheave is an easy deal if you use the Whizzer unit, either the WhizzerUSA part, or the Vintage design, whether new or used. Long belts are indeed availbe, this bike uses a very long belt, and a WhizzerUSA sheave.

Hi MotorBikeMike -

I went to the Whizzer site. The Whizzer sheave assembly may be an option. Quick calculations tell me to expect to spend about $90 to get an assembly to my door. I may go that route rather than do an original reverse-engineering of a tractor implement store pulley. (A bad drilling or cutting mistake will wipe out any hoped-for cost savings.)

The Whizzer site does not give the diameter of the sheave. Can you provide? I am guessing it is about 14 inches. The sheave diameter will give me an idea what diameter pulley to use on the drive output shaft for my purposes.

Thanks,
MikeJ

Hi MikeJ,

The Whizzer sheave is 15". The sheave from Whizzer USA is made to fit 105 spokes and is difficult to affix to smaller or larger spokes. The vintage version of the sheave has small thick washer & screws and will fit different spoke sizes. The vintage can be purchased from Memory Lane Classics in Ohio and the cost is about the same with the needed hardware. I think Memory Lane has them in stainless steel or plated [less money].

Have fun,

MikeJ,
How did you make out with the rear belt set up you were investigating??
