2012 In Frame, 4-Stroke, Build-Off

EZ Motorbike Company is sponsering this event and will supply plaques for the winners. This is our way of saying thanks to everyone for outstanding support of EZM.

Rules for the EZM 2012 four-stroke in frame build-off:


1. Only 4-stroke motors [any size, age, or brand], and must be mounted in-frame.
2. Any 4-stroke motor or kit can enter, NOT limited to EZ Motorbike kits or Q-Matic drives.
3. Must document start of build with pictures.
4. Must post which class you are entering.
5. Will start now, and end on American holiday 4th of July 2012
6. Any build started but not completed can enter
7. Existing bikes undergoing major changes can enter [different type or style motor, different frame, etc]
8. EZM will not judge contest, but ask others to do so.
9. Entry must be completed before July 5, 2012
10. Production motorbikes not eligible [Whizzer, Tomos, etc]
11. Any one in any country can enter, not just America.

Five Classis:
Cruiser
Stretch cruiser
MTB
Vintage [bike must be older than 1980 or American made]
Whizzer [Vintage or New Edition]

A few comments:
We will add a Whizzer class, however only certain versions of the kit can enter.
NO factory-produced bikes are eligible. The following cannot be entered. Any vintage Whizzer Sportsman, Pacemaker, Ambassador, or Whizzer special. Another example of Whizzers not eligible would be a restored vintage Schwinn WZ/S4, as this would be considered "Restoring", not a new build, as the bike was made for the Whizzer motor kit. Can not enter the following New Edition Whizzers..1999 Classic, 2000 Sportsman, 2001 Pacemaker II, 2002 Pacemaker II, 2003 Panther, 2004 - 2007 NE5, 2007 Ambassador I, 2008 Ambassador II, and 2008 -2009 NE-r.

Whizzers that can enter. Any bike with a Whizzer motor kit [vintage or new edition] installed on a bicycle [Schwinn, Roadmaster, Huffy, Murray, etc.]. Any Whizzer produced bicycle with a non-Whizzer motor.


This is a Build-Off, and must be built from scratch. Use simple logic to see if your bike is acceptable. An example would be to use a Whizzer bike and install a 49 CC 4-stroke motor, or use a Whizzer motor on a non-Whizzer frame. If you have a 2-stroke motor on a bike and install a 4-stroke motor, this would be allowed. If a current bike were being upgraded with a different motor type or style [installing a 79 or 99 CC 4-stroke motor in place of a smaller 35 or 49 CC 4-stroke] would be OK. If a bike were being converted from a rack mount to an in frame 4-stroke motor it would be acceptable. Minor changes on an existing bike such as tank, wheels, lights, paint, drive systems, same motor style only larger or smaller, brand, etc. aren't acceptable.

Hopefully this will offer an equal playing field for the DIY builder. If anyone needs more information about the rules, please contact me. We are still waiting to see who will judge the event, however we can get started, and as a last resort we will use the same judging system used on a previous Build-Off. [Voting by members].

Lets have a lot of fun, see some exciting ideas, and put a few more 4-stroke in-frame bikes on the road.

Just start posting information and pictures.

Have fun,

I'll be entering the Vintage / American class:

"I love the qmatic and will be upgrading to the HF99cc predator in the near future".

I said that I'd be upgrading to a HF99 back then, and now it is done. I cannot believe what a difference this engine has over a HS49, I should have upgraded earlier in the year :devilish:.

A special thanks to Quenton for the help on making it all come together. :bowdown:

Hi everyone!
Been busy and have not posted in awhile. Added a SBP air filter, large saddlebags, & front fender support. The whole build has been fun and I'm happy with the results. 100_0343.jpg100_0336.jpg100_0332.jpg100_0333.jpg

Felt Cruiser Back in Black

Hello all,

I am frantically trying to finish this build for the deadline. This is my second build. My first build can be seen in my photo gallery but I needed parts for this build so it got stripped down and returned back to a nice pedal power cruiser.
This bike has been a blast to build. I went with the SBP shift kit so I could have a hub with a few gears. I live in a hilly area (is hilly a word?). Anyway, I decided on the Sturmey Archer 3 speed hub which will match style with front hub. I have laced all my wheels myself and sent them out for truing and tension.
The frame is powder coated but I have painted everything else that is not the original color. I swapped out the SBP clamps for some stainless units I found on ebay and hardware store. I also used some clear mylar on the frame where the clamps are.
Here are a few pictures to show some detail. The bike is further along now but still have some cable work to do before I post final pictures2012-08-19_15-39-38_70.jpg2012-08-19_15-39-50_759.jpg2012-08-19_15-39-58_814.jpg2012-08-19_15-40-30_171.jpg
 
Felt Cruiser Back in Black "Finished"

Ok, Here it is in completed form.
I would like to enter this in the Cruiser Class build-off.

It is a Felt Canvas frame kit. I had the Felt wheels from another cruiser and I found the Abraham Linkage at a shop in Mountain View. CA.
The engine is a repainted HS 49cc.
I originally had the EZM trans slated for this project (will be used on build#3) but I wanted to go with a shift kit on this build so I went with the 4G t-belt trans.
