MOTORIZED BICYCLES:   Rear wheel hoops posted by: Davis on 2/27/2001 at 10:21:22 AM
How do those belt drive hoops attach to the rear wheel on Whizzers and other belt drive bikes?

I think you might mean the sheeve. It depends on what WHIZZER you are working on. The add on kits for bikes just had sloted head srews, nuts and washers. The ones put on by
WHIZZER had a bolt, clip and a nut. Either way, think about the direction the belt is going to pull on wheel.

MOTORIZED BICYCLES:   WHIZZER posted by: John Martin on 2/17/2001 at 3:15:14 PM
This is a question for you WHIZZER guys. My PACEMAKER has a S/N on the "hanger bracket" of 7795.
It has the typical front fork for a PACEMAKER and correct head badge of WHIZZER PACEMAKER. It has
a "loop" frame. Could this be a SCHWINN built frame for WHIZZER? Would the date
be 5-4-51? It has a rear rack like the SCHWINN S-10. Could all
this be correct?
Thanks.

ALL Pacemaker frames where made by Schwinn, except for the first thousand (1000). Yes, the date is 5/4/51.

MOTORIZED BICYCLES:   Got a question for Y'all... posted by: Rif Addams on 2/16/2001 at 8:53:12 AM
Hey everyone,
I was sitting here enjoying my morning coffee gazing out the window at the newly fallen snow. When suddenly some more wierd ideas popped into my brain.
Does anyone out there have photographs or video footage of motorized bikes racing? Any racing. Drags, (dirt) flat track, road, etc. type racing. I would love to see Moto-Bikes in competition!
If anyone has this sort of thing, could you send copies and perhaps a brief description?
If nobody is doing this, WHY NOT?!?! :-}
last summer the local Velodrome allowed a group of whizzers on the track, during the big local bike meet. I wish I could have seen it!
Thanks,
Rif

MISC:   Memo From The Editor: New Issue of BikeRod&Kustom posted by: JimW. on 2/14/2001 at 7:36:20 PM
Volume 2'Issue 4 may be found at the usual location: http://bikerodnkustom.homestead.com

It contains an interview by Rif Addams, with Larry Louterback, builder of hyper-powered motorized bikes.
Legal motorbikes are restricted as to power and speed capabilities, which may be a good thing, as most bikes tend to disintegrate at sustained speeds over 30 mph. The Outlaw Mr. Louterback, whose creations can cruise at 50mph, has taught himself all the tricks of making bikes handle and hold up well within that performance envelope. He shares his knowledge with Rif, and BR&K’s readership. Don’t try this at home,
kids; but if you do, be sure that you (or your surviving loved ones) send us pictures.

We review yet another carbon-fiber bike D.I.Y. plan-set; this one for an ultra-light off-road bike by Canadian Richard Langlois. This is an excellent way of getting acquainted with carbon fiber bike building, and can lead to applying the knowledge gained to the making of Kool Kustom Karbon Bikes.

Steve Nurse is an Australian Engineer who has some innovative bike ideas. He’s come up with a system called “CHAMELEON” which could revolutionize community bike programs. By combining modular sections, it’s possible to put together a single-rider bike, a tandem bike, a bike truck, and lots of other useful and fun HPVs. We show his designs in this issue’s Design Lab.

Editing a webzine can really cut into other leisure-time activities, like Bike Kustomizing, for example. The
Editor of this ‘zine, having zero time to actually build bikes, has lately confined his energy to his sketchbook. He has scraped some of his Photoshop sketches together for a pictorial feature.

Just in time for your late-Valentine gift needs, comes our free download “Bad Girls Ride Bad Bikes” T-shirt art by Gary Hallgren. Not only can you give the love of your life a snazzy (if tardy) gift, but you can brag that you made it yourself, with your own little ink-jet printer. (Maybe you can get her to iron it on the shirt herself.)

Lastly, but certainly not leastly, we have a flock of new creations in our Gallery. These are by Larry Lujan,
Janos, Rydjor Bikes, Rif Addams, Brandon Flannery, and INSIGNIA of Australia.

Fond regards until our next encounter,
Jim Wilson

MOTORIZED BICYCLES:   How cold it is! posted by: Rif Addams on 2/9/2001 at 9:30:47 AM
I was sitting here at home on Wednesday, staring out the window at the sunlight casting it's golden rays upon the world. I was nice and warm inside, drinking coffee. The roads were nice and dry.
The temperature was at around 42 degrees F.
Suddenly I just couldn't stand it! I quickly put the motor back on my 66 Schwinn Typhoon Deluxe, and was on my way! It was chilly but bearable with my layers of clothing and scarf. Around 3:00 P.M. I stopped over at a friend's house and hung out for awhile.
I didn't realize quite how late it had gotten, and how much the temperature had dropped. I had a 5 mile ride ahead and the temp. was now down to around 34 F. with the wind chill of travelling at 20 M.P.H. I had to stop about every mile to thaw my hands and face.
WOW! What a rush. It was so invigorating, good for the body, mind, and soul!
I was a giant popsicle when I finally got home...

I must be a masochist or somethin'! I just got back from doing it again! It is 43 degrees F. outside; but man, I gotta RIDE!
Moto-biikes are absolutely the bestest fun in the whole wide world!
I can't get enough, I just wish my Moto-bike would go faster...
Well gotta go get some coffee to thaw these old bones out,

MOTORIZED BICYCLES:   whatizit?!?! posted by: Rif Addams on 2/2/2001 at 11:00:54 AM
Hello, Hooray!
awhile back a friend of mine gave me a little 49cc, single cylinder, 4-stroke motor with integral gearbox. The only markings on this thing, (which is about the size of a whizzer motor only a bit wider)are: cast into the case '49cc', and stamped onto a machined pad '0044'.
The only emblem on this thing is the clutch cover which is kind of a flying arrow looking thing. Similar to an old AMF symbol. I've been to damn near every motorcycle shop in town, including the guru at our local motorcycle salvage yard. Nobody knows or they don't care.
I'd like to know what it is, so I can get the necesary parts to get it running again.
I have big plans for this little gem.
You see when I was 17 years old, I came across an old poster that was a reprint of an advertisement for the Flying Merkel motorcycle. I have been infatuated with this bike ever since. I would like to do a scaled down bike using the Merkel as my inspiration. I've been collecting bike parts to do this on and off for a couple of years now.
yesterday I did a rough design sketch and cataloged the parts I have. I'm getting there.
It'll be awhile as I have a couple of projects that are taking precedence over that at the moment, but I'm almost ready.
I just thought I'd share some more of my adventures in moto-bikeing with y'all!
Thanks for listening to my endless ramblings,
Rif

Well,
Thanks to this wonderful old bike/ motobike community I now know what this motor is. I e-mailed someone who I thought may have had an idea as to what this was, and sent a pic.
It turns out this is an old harley 50cc dirtbike motor. This persons neighbor has one, so he went over to look at it, comparing it with the picture and e-mailed back confirming this.
He believes it to be early 60's, but I can't help but wonder if it is early 70's when AMF took over, due to the emblem on the case. I will however, take his word as I have no real Idea; and he seems to really know his stuff!
Thanks once again Doug! I greatly appreciate the help!
Rif

Hello. I just left an e-mail for Rif on his generous offer. I also have questions for anyone about a Sears motor that is supposed to be identical to these. Can you order parts and manuals from any Sears store? Do they still sell them anywhere or did the lawyers kill them off?

If your offer is still good I'd really appreciate a copy of the parts manual sent to:

Also are you aware of parts being available thru any distributor?
Much thanks!

MOTORIZED BICYCLES:   More on Clip on cycle motors posted by: Simon Dew on 1/10/2001 at 9:11:46 PM
I've clipped the motor onto my 57 Herc by braising two homemade lugs to the forks. This seemed the most reversable and simplest method. It goes like a charm and extends the range I would travel on my bike 100 fold. I have been driven off the road by people wanting a look. I would be very interested to know who manufactures the motorized skate board motors which I think would be ideal for bikes. Any ideas?

MOTORIZED BICYCLES:   Homemade motorbikes posted by: Eric on 1/3/2001 at 2:16:31 PM
For those who are curious about the 50's art of homemade motor bikes here are a few of the tricks used for building and powering your bicycle. The motor is a horizontal shaft 3 to 4 horseposwer 4 stroke Briggs and Stratton (that was the only lawnmower available to us in the 50's, any substitute with the same dimensions would work). The motor is fastened to the right side of the bike, it is bolted onto a piece of angle iron with at least a three inch lip. The angle iron is fastened to the v in the bicycle frame with u-bolts. The angle iron can be slotted in a front to rear fashion where the motor bolts down for ease in adding or loosening tension on the belt. The head bolt of the motor should be even with the top bar on a boys bike so a bolt from the head can be loosened and a metal strap can be fitted to wrap around the bar and afford a tight fit of the motor against the frame. The simplest drive will be a centrifical clutch added to the crankshaft and a sheave pulley which can be found at a Wizzer dealer (we used to rob the sheaves from water cooler pulleys in the junk yards). This pulley is mounted to the spokes of the rear wheel on the left side and attached with lock washers, the proper spin balancing of this pulley is imperative. Some of the smaller bikes such as the sting ray which came out in the late 50's or early 60's had small rims and the pulleys were carefully spot welded to the wheel proper. A v-belt of the right length is then fitted around the wheel pulley, the wheel is attached to the bike and then the belt is fitted around the centrifical clutch. The chain may be left on the bike for use with the pedals for breaking purposes, but we fitted our bikes with front and rear hand brakes. This is the basic drive train, many knowledgeable youngsters fitted their bikes with homemade grip throttles, secondary gas tanks, on off switches, running lights, extended pipes, removed pedals and added foot rests, added tensioners that worked as hand clutches to accomplish wheelies and fast take offs, and some of these creations were extremely fast. Of the hundreds of bikes I saw built and ridden I never knew of one serious accident and we rode these bikes in traffic, but that was in the 50's. One boy built a chain driven model, the pedal shaft was removed and a ball bearing shaft was constructed with sprockets on each side. The motor was fitted with a centrifical chain clutch and attached to one end of the shaft and the right side of the shaft was chained directly to the original sprocket on the rear wheel. This bike was clocked in excess of 55 mph, a battery was tied down over the front wheel to keep it from becoming air born. Because of the gear ratio the take off was extremely slow but boy the top end was incredible. I could go on and on with stories of those most wonderful times and the ingenuity and creativity that went into some of these machines but I hope the little I have shared will prompt others to use their imaginations and get with their child or grandchildren and share an experience that will live within your family forever. Unfortunately we have not been graced with grandchildren yet, I resurrected one old motorbike many years ago with my son. I plan on building one or two with the neighborhood youngsters this summer, I am now in the process of gathering the needed parts. At 51 I shall ride like the wind and be the first to test pilot the "machine" while the young ones look on in anticipation. Feel free to email me if you need any suggestions for your homemade motorbike.

Eric,
Thanks for taking the time to enter that.
I'm on a hunt for a side-shaft lawn mower engine. All I can find at my local dump are vertical shaft engines.
Have you ever been able to do it with a vert shaft?

Thanks

          RE:RE:MOTORIZED BICYCLES:   Homemade motorbikes posted by Eric on 1/6/2001 at 8:37:11 AM
Ken,

It would be quite an engineering task and not worth the effort and extra cost to make a changeover. Try your local shade-tree lawmower repair guys, they should have plenty of used motors cheap, especially this time of year. If anyone is interested I will gladly email step by step photos of the motorbike project as it progresses.

          RE:RE:RE:RE:MOTORIZED BICYCLES:   Homemade motorbikes posted by Gordon on 3/3/2001 at 9:30:42 PM
Why not find a snow-blower or roto-tiller motor. These are horizontal shaft, and the new 2-stroke snow-blowers would be a nice light motor. Unless you live in the south, I guess.

Howdy From Texas,
Thanks for all the emails and replies, it looks as though there is great interest in the old art of the homemade motorbike. This should be fun, as soon as weather permits I will send anyone who either replies to this section or emails me directly, a photo of parts I have accumulated and necessary for the project. Once you see how simple the approach is you will be engineering your very own motorized bicycle.
