The Screaming Rabbit -- Finished (new video)

[Georgeediii]

I have been wanting to build a motorized bike for a while so here we go. My last build for the MBBO was powder coated and looked like it came straight off the floor at K-mart. This time I am going the opposite direction and keeping it crusty. Since I don't know anything about motorized bikes, I will be breaking all the rules and doing it my way. I will admit up front that my "big idea" might not be entirely possible, but I will be putting it to the test. As for the name, I am undecided between the Dragonfly-er or the Screaming Rabbit. I think it will become obvious why either name will work as I get into the drivetrain. Here is a taste.





Good luck to everybody! By entering, you've already won.

A 5 horse should really fly, hope you are planning good brakes!

Cool. Watching!

I have heard that rabbits only make noise as they die. I've run over a few throughout the years and sure enough its the only time I've ever heard them scream.
You may want to consider this as you pick one of the two names.....

That is the only reason I am considering that name!

Good parts pile. Be careful!

 

[ThatGuy]

this build will be interesting to watch!!

Suicide rider,will be a crazy build.
Live fast,die young & leave a good lookin corpse behind.
You don't need brakes.

OH YEAH. I dig speed:!
So, watchin.!
Hope your not using solid forks.

Nice starting point! I'll be watching for sure. I kinda did this route a while back with the 56 briggs on a 43 CWC frame for Bonine. It was pretty fun working it all together. I have a few motorized bikes and the briggs is my favorite.

Good luck with the build!

I like the parts collection and motor for Scweamin Wabbit.

First things first, I need to get a roller together. In the plan I had in my head I thought I would piece together the original fork with the business end of a monark springer that I picked up a while back. I had to do some flipping around but I was able to get it to work the way I had envisioned, but..... without the other half of the monark I have to balance limiting the action with making sure it doesn't fall apart. It looks good but it makes me a little nervous, especially on a motorized build.

I have a couple other springers to choose from but I am not sure about them either. Next option is this standard Schwinn knock off. Not only does it look kind of ordinary, I think it is off an Electra and it is the kind where the braces are welded to the fork just above the dropouts. At least with this one I wouldn't have to worry about it holding together.



Third up is the old Rat Trap. I don't see a lot of these used on motorized bikes, which makes me think there is probably a reason.




Any input is appreciated, but may also be ignored.

The rat trap kind of looks like an old Indian springer. That's got my vote.

 

[Georgeediii]

Things are slow moving over here and with a week long visit to the in-laws on the horizon, it might be a while before I can get it motorized. I was able to remove all the decals from the frame and do a little Dremel work in order to get the rat trap to accept a bigger axle.

At least now I have a roller and will be able to figure out a level motor mount.

 

[horsefarmer]

If you are really in doubt about your front fork, maybe something from a Moped would be better maybe keep the wheel and brake too?

 

[Georgeediii]

I am heading out of town to the in-laws for a week so I have decided to wait on mounting the motor until I get back. In the mean time I found a slightly mangled Sears / Raleigh knock off at a police auction that I was able to pick up for 5 bucks. I really just wanted the pedals but I am cleaning up the grips too just in case. Unfortunately the pedal adapters are going to cost me triple what I paid for the bike but the pedals match the tires so well I feel compelled to use them.



I also mocked up these Elgin guards I picked up with a PeeWee replica in mind. Doesn't look like I am getting to that anytime soon so they are being considered for this build. IF, IF, IF I use them then I have to figure out whether to paint and patina them to "match the rusty chrome fender, or to do the fender as well.

On the pedals, maybe you could change the white blocks to a set with the right thread?
