Hello, here at EZ Motorbike we got to thinking that the MB Community would be wanting to know what we are doing, and a little of how we do it. Here at EZM our Engineers have been been designing and building Motorized Bicycle Drive systems since 2004.

In 2008 we decided that the Community, wanted AND needed a new 4-stroke kit with superior features, reasonable price and outstanding value for the money. This kit needed several features to be successful in fulfilling the needs of the American Motor Biker. Some of the features I will now list.

#1 True Under 50 cc, ours is actually 49cc, (in the majority of areas under 50cc is the law) displacement with good performance {our expectations of performance are actually exceeded in our choice of the HS 142f/Honda GX50 platform}.

#2 UNDER 2 horsepower. (The law is important to us, and we KNOW that the Feds, and States will be cracking down, it is just a matter of time).

#3 4-stroke quiet performance with High MPG (Here we are getting reports of 140-180+ MPG)

#4 Designed to do from 0 to 30-35 on level ground with average rider on board. (Again legal issues).

#5 A truly Engineered, well tested product (We have literally 1000's of hours of "in the saddle time" with some of the most trusted MB Community members, no speculation here!)

#6 A good STABLE drive that will give years of reliable performance ( both the Silent Power, and the Q-matic are ready for a very long life on the road).

#7 A strong company with a Dealer Network to better serve the Owners of the MB (here what we did, in the beginning, was to draw from our experience in the MB Community, and gather some of the best {and well known} individuals to perform "Beta Testing" across the country in a variety of different conditions, we are very happy with the results of that decision).

#8 Provision for, thought, planning and Engineering to help make the product more usable for people with disabilities, weaknesses, or other issues. This concept really pushed the development of the Q-matic so that pedaling would NOT be necessary. In this we are well pleased, the HS or Honda start easily, require no pedaling for 0-30+ MPH and no skill or finesse on the clutch handle (Tho I, and several others LOVE their manuals!).

#10 AMERICAN made, wherever and whenever possible. We are forced to use some China parts, as American parts are not availabe, or sometimes outrageously priced. The entire Silent Power, and Q-matic Primary Drives are built in USA.

#11 Weight! yes, here much consideration was given. The current weight of Q-Matic Primary is under 6.5 lbs this is with the heavy steel auto clutch, which we are grateful to Max Torque, for helping us in refining the operation to fit our needs, this clutch, in its basic format has been made in USA since the 1970's.

#12 Embracing space-age technology,. we use a special aluminum alloy to manufacture the Q-matic, that is made in only one US mill, and stockpiled in ONE eastern warehouse, while this may add some shipping delays in our manufacturing, it is the best alloy for the bends, and is NOT prone to cracking! With the addition of the Steel Max Torque, we felt it necessary to step up to the expensive aluminium alloy, to balance out the overall weight of the engine/Drive combo.

A few specs to consider......

Average weight of HS 142F 9lbs 13 oz
Our Primary is approx 2" thick
This puts the engine and Drive at 16.3 lbs which is 5.7 lbs, yes about 33 percent lighter than a common 4-stroke engine WITHOUT Drive mentioned elsewhere on this site!


Here are some of the engines that have already been fitted with, and run EZM Primarys
RS EHO35
HS 142F
Honda GX50HA
HF 79 Greyhound
5hp Briggs and Stratton
9 hp Briggs and Stratton "Animal"
Other engines adapters in design stage

To make these engines work efficiently, we at EZM are able to change the FRONT ratio from 2.06 to 2.935 easily, with a variety of custom made billet pulleys. We currently do this in 7 different ratios!

Rear ratios are availabe from 9 to 1 thru 21 to 1 in 12 basic ratio steps. We believe that our Primarys offer the most flexible drive ratio system ever seen in a single-speed Motor Bicycle.

We are shipping DAILY! If you are ready to own America's best in-frame 4-stroke bicycle engine kit, get a hold of your local EZM dealer and order one now! IF you have no dealer close to you a couple of options exists, one being for you to look into becoming an Authorized EZM Dealer, contact East or West coast EZM Operations (yes we answer our phones on weekends), or contact any EZM dealer that you like.

Thanks for reading;

Mike

NICE! belt-driven w/spring loaded tensioner. perfect. what kind of work would it take, to convert my existing chain drive gearbox to one of yours?
or any other gearbox to yours, for that matter.

Does this mean that you now have adapters available for these engines?

Hi Finfan, thanks for asking! the engines listed do NOT need adapters EXCEPT the RS EHO35. any engine with a 5/8 shaft and flat mounting surface will only need up to 4 new holes drilled to mount to the engine. RS has no shaft sticking out, so one of our dealers made an adapter for his. I have not made one yet, but it can be done as needed.

The "problem child" engines are the ones with the short tapered shafts, but we are working on that also.


To Spunout, your engine is the type with the short tapered shaft, I have not recieved an engine to pattern off of yet, but one is expected here.

Very nice looking and from the video, a nice running setup. I've been thinking of building a couple of the 4 stroke kits to use as transportation in campgrounds. I await your true for sale listing for the kits.
