Developing new products for EZM

[Quenton Guenther]

Our current projects include a 12 volt alternator electrical system and 2 speed drive system.

Several [3] EZM authorized dealers are currently working on a 2 speed automatic drive system. So far two are under testing.

While it is true the EZM 4-stroke kit doesn't need to shift, we are still looking into the 2 speed drive system for other optional uses.

So far the 12V electrics have traveled down several paths. One path considered is to use the magnets on the current flywheel to activate [excite] a series of coils. Another path considered is to collect power from known belt driven alternators. And the final path is conversion of AC to DC and control modules to charge a small battery.

EZM is always looking at ways to enhance the motorbike experience, and welcome any input that may speed up the process.

Have fun,

Pictures! Pictures! We want pictures!

Keep working on the 12 volt electrical system. Hope it will be cheaper than the system I developed. I will try to reduce cost in anyway I can, but now my solution is just too expensive. http://www.youtube.com/watch?v=laGa_wgYxqY

Hi, just an update,

SBP is working on a adapter kit for the Q-Matic to install thier shifter kit.

Still working on 12 Volt system.

2 speed is still under development & testing.

New HD belt now in production kits.

Shipping with 2 position idler pulley for alternate belt sizes.

Lighter idler tension springs for use with HD belt available.

Dealer testing has passed 10,000 miles [one dealer in AZ has recorded over 3900 miles]


Have fun,

what are your ideas on how to spin the alternator or whatever it is you plan to use

i think it would be nice if we could put a sprocket on it and attach it to our final drive chain

then it would be VERY universal

i have been wanting something like this for a LOOOOOOONG time now

That's not a bad idea - have it replace the idler sprocket for the tension adjust...

any sort of update on 2 speed or electrical

how does the 2 speed work

 

[Quenton Guenther]

Here is an early picture of one of the 2 speed systems we are considering.
A version of this will use primary belts in place of the chain.

Because of increased orders we have directed our attention to drive production and the electrics have been put on the back burner for the time being.

I know you have said before that you were worried about the generator or alternater taking away power
You say your drives do 40

I know I for one would not mind maxing out at 30 to be able to have a practical lighting system (one that does not require plugging into wall at home)

That 2 speed pic looks very interesting
Manual shifting I am guessing?

Hi Jared8783,

Although it is possible to reach or exceed 40 MPH, we don't promote the idea. The EZM motor kit and the Q-Matic drive leaves our assembly geared to take the average rider on level ground approx 32 MPH.

There are several ways to control the top speed to keep our product legal because most of the states require 30 MPH or less to qualify for motor assisted, MoPed, or motorized bicycle status. One way is to setup the ratios to have the motor run wide open and max at the desired speed [like running a car in first gear all the time]. Another way is to set the ratios to cause the motor to run out of power before it exceeds the desired top speed [like running a car in third gear all the time]. If the ratios are set to allow maximum RPMs the motor can easily be over revved and cause damage. We already know it isn't wise to run any motor WOT all the time, and it appears many motorbikers would do just that. If the ratios are set to run out of power, many heavy riders would have to pedal assist to get started or climb a large hill.

Other motorbike companies have fixed drive ratios and require the rear sprocket to be changed to arrive at the desired ratios. EZM has developed a system that allows simple changes in the primary drive to alter the primary ratios from 2.62 X 1 to 2.935 X 1 allowing the ability to "fine tune" the sytem to fit individual needs. Of course the rear spocket can also be changed to add even more ratio options. In other words it can maximize top speeds or climb the nearest hill, or aid heavier riders in overall performance with a few minor changes.

Another consideration we took into account was motor braking and reducing the stress on the bicycle brakes. Most companies use a "free wheel", and we totally disagree with the concept. If cars had "free wheels" the brakes would wear quickly because the motor would not longer aid in slowing it down. The Q-Matic drive stays connected to approx 18 MPH and then disconnects to allow the motor to idle at a stop. During the process if the throttle is reduced the motor will in fact reduce the speed to aid the braking system of the bike. When the motor isn't running the only item in the Q-Matic that turns is the clutch bell housing [very light weight] and the bike can be operated in a normal fashion.

Hopefully we will be able to return to designing a electrial system soon and doubt it will use much power to operate.

The 2 speed clutch is totally automatic and doesn't require a manual shift [illegal in most states].

Have fun,
