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,

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!

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?

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.

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?


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

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.

REPRODUCTIONS:   Need values for 3 reproduction bicycles posted by: Sharon Nealeigh on 1/2/2001 at 11:27:15 AM
I am trying to value three reproduction bicycles: A Schwinn Black Phantom 7-speed reproduction (black and red); a Columbia modern reproduction of a Five Star Superb bicycle (green and white); and a modern reproduction of a Western Flyer bicycle (red and black, gold trimmings). Does anyone know where I can get some information with regard to retail replacement value on these bicycles? I'm "spinning my wheels" trying to find the right websites or sources of this information.


   Clip on Bicycle Motor posted by Simon on 1/2/2001 at 5:46:25 PM
My brother just gave me a small English clip on Bicycle motor. It has an egg shaped petrol tank and drives the front wheel (I an fairly confident of this) directly from the crank shaft which has an abrasive finish. It simply drops onto the wheel and drives it. I assume that it works on the same principle as a golf cart in that when you throttle off the motor simply stops. The Amal carb has no idle jet which tends to support this theory. There is sadly no identification on it apart from the Wico-pacy mag and Amal carburator, which is why I assume its English. I have looked on other Moped sites and have only confirmed that it isn't a Trojan Mini-Motor or a Power-Pack. If anyone can help me with identification and or the precise method of attachment I would be very pleased. I have plans of attaching it to my 1957 Hercules 28" bike and then watch out New Zealand!

http://www.ebay.com has become the price book on collectible prices.

Schwinn Black Phantom 7-speed reproduction
Available at http://www.memorylane-classics.com for $1700
Three sold on Ebay recently for $946, 999, & 1425. All by the same seller, 13Mark. %517 seems low but I do recall a sub-$100o dealer price on them as year or so ago.

Columbia modern reproduction of a Five Star Superb bicycle
I purchased one new in the box on Ebay 1.5 years ago for $500

reproduction of a Western Flyer bicycle
Rideable Replicas at http://www.hiwheel.com had up to a year ago for $350-400. They have since sold out.

Your description souds like a Berini. Made in the Netherlands by Pluvier and, although they look nothing like each other, closely related to the Cyclemaster. Its a 32cc motor. It should clamp to the front forks of a bicycle. I can probably fine a diagram of how it fits if you need it. Send me an e-mail if you do - I'm don't visit here often!

MISC:   The Golden Age Of Moto-Bike Building posted by: JimW. on 1/2/2001 at 7:11:31 AM
In my youth, in Western KY in the '50s, a lad could acquire as many gasoline engines suitable for bike power as he wanted, for virtually no money. When my family moved there,
the area had just got electricity, through the Rural Electrification Administration, and a new hydro-electric dam in the area. Until then, people's washing machines were
powered by engines. In many cases, the old machine, with engine, was dumped into the closest gulley, when they could afford to buy a new electric unit. These were free for the finding. Others ended up in city dumps, usually free. Some ended up in junkyards. A lazy child with five bucks could buy one from a junk dealer.

At one time, I owned three of these engines. I had two of the commoner cast-iron-block Briggs and Stratton units. My favorite engine, though, was a horizontally-opposed two-cylinder from a Maytag. It was cast in aluminum alloy, and
was really beautiful. I used it on a home-made gokart, but it would have been beautiful on a bike.

AGE / VALUE:   Motorized Bike posted by: Tom Bartlett on 1/1/2001 at 8:59:11 AM
At the risk at sounding like a "commercial", if you are interested in seeing a motorized bike that really works, can still be pedaled, built in the the U.S. and backed by a factory warranty, check out the motorized bikes at www.zipcycle.com. We are a company of biking enthusiasts who wanted to create a true "dual-purpose" motorized bike. Our bikes can still be enjoyed as a bicycle (have you ever tried to pedal a moped?), have a great "classic retro" look, and parts are available nation-wide.

   RE:AGE / VALUE:   Motorized Bike posted by JimW. on 1/2/2001 at 7:07:13 AM
That looks like a nice, clean installation. Is 20mph the actual maximum speed, or is it governed to that level?
If you send one to Rif Addams, BikeRod&Kustom will run his
road test of it.

I don't know about the "Bronco" designation, but the Cox bike
motor is still, as far as I know, still in production. A friend
of mine bought one about five years ago, to mount on a Schwinn tandem.

My friend bought his at America's Hobby Center (AHC)here in
New York. Cox is a leading maker of model aircraft engines.
The bike engine is pretty much identical to their larger
model aircraft engines. Check a recent model plane magazine
for the company's address, or run a web search. I'm sure they
can send you a manual.

   RE:RE:RE:RE:MOTORIZED BICYCLES:   cox bronco posted by Clark on 1/12/2001 at 10:47:15 PM
Thanks for the info, I called AHC and they claimed they didn't know anything about bicycle motors. They thought he might have gotten a large airplane engine and modified it. Next step is to call Cox and see what they say. Clark

   RE:RE:RE:RE:RE:MOTORIZED BICYCLES:   cox bronco posted by JimW. on 2/1/2001 at 7:55:59 AM
My pal's motor was definitely bought from AHC, and it was
set up as a roller-drive bike motor, and labelled as such.
The quality of information at AHC (like most places) depends
upon who happens to answer the phone. Checking with Cox is
a good idea, as they can tell you who carries the motor now,
if AHC actually doesn't anymore.
