MOTORIZED BICYCLES:Pulley / drive wheel calculations posted by: Rif Addams on 1/21/2002 at 10:42:45 PM
Hi All!
Here's something that may be of help to you Moto-Bike home builders.
I finished working this stuff out this morning- I've been playing with it on and off for a few months now.

These are formulas to calculate speeds of driver to driven and then to calculate speed. Please note: These calculations do NOT include variables such as power: weight ratios, resitance, drag, loss of torque / power through suspension etc.
When I do this calculation I am always a little conservative and round down to the nearst whole number to help compensate for those variables.
This is only to get one in the neighborhood when building a Moto-Bike.
D= Driver diameter
S= Driver speed in R.P.M.
d= driven diameter
s= driven speed in R.P.M.
R.P.M.= Revolutions Per Minute
F.P.M.= Feet Per Minute
M.P.H.= Miles Per Hour

To calculte the speed of the driven wheel or pulley the following formula is used:
D x S
------- = s (in R.P.M.)
As an example: if the driving wheel is 2.0" in diameter, and it turns at 3500 R.P.M., and the driven wheel is 26" in diameter; we would then multiply 3500 by 2.0, then divide by the diameter of the driven wheel.
3500 7000
x 2.0 -------- = 269.230 = 269 R.P.M. (rounded down)
---------- 26

Now, to convert from R.P.M to F.P.M we do this:

s x d
------ = s ( in F.P.M.)

Using the same arbitrary numbers from above-

269 6994
x 26 ------- = 1748.5 = 1748 F.P.M. (rounded down)
-------- 4

To convert this from Feet Per Minute to Miles Per Hour is simple multiplication-

s (F.P.M.) x .01136 = M.P.H.

Again using the above numbers:
1748 F.P.M x .01136 = 19.85 M.P.H

To review-
DxS / d = s rpm
sxd / 4 = s fpm
sx.01136 = s mph

Does anyone see any mistakes or errors with this theory, or in the formulas themselves? Anyone have anything to add?
Just trying to help with some info...

MOTORIZED BICYCLES:Travis motor? posted by: Mark on 1/10/2002 at 9:37:01 PM
I was wondering if anyone could help me out with info on my Travis bicycle engine. I was told that it was bought in 1948 -50, don't know if this is correct. It sort of runs, but I bought it with no idea if the spark plug is correct(or the gap). I don't know what the mixture is as well. It has a Zenith carb that may need to be replaced- I have pictures of it. I would like to get it running at some point- I get closer and closer to getting it to run/ but never good. Has great compression, spark. Also-any idea on what something like this is worth?

Hi mark,
I was hoping you could send a picture or two.
I'll have to look and ask around, but I think I heard some bike buddies talking about one of these. I don't know for sure but I'll ask around and show the photo.

   RE:RE:MOTORIZED BICYCLES:Travis motor? posted by George Stratton on 1/14/2002 at 10:38:52 PM
The years sound correct because I remember seeing many of them back in high school around that time. I believe the engine was manufactured by Power Products who also manufactured the engine for the Monark Supertwin of the same era. The Travis mounted over the front fender and operated by driving the front wheel by running a small diameter drive wheel directly against the bike tire. You could raise and lower the engine with a hand lever like a clutch. Check the Vintage Motorbike Club, and you will find people looking for one. George

REPRODUCTIONS:   Schwinn Black Phantom posted by: Weldon on 12/23/2001 at 5:06:09 AM
What is the highest dollar value someone should pay for a reproduction model of the Schwinn Black Phantom MIB.


   RE:REPRODUCTIONS:   Schwinn Black Phantom posted by ChristopherRobin2@starmail.com on 1/9/2002 at 1:31:35 AM
I see one in a shop and they are asking $2000.00 for it. You can find a old origonal one for somewhere less on e- bay. Please read and take Jim's advice to heart. This kind of money can really get you set up with something really nice and enjoyable. If you had or wanted to have one as a kid, (Are you from the Phantom bike generation?) (late 1940's 1950's) and you are fairly wealthy and have the money to throw on a toy, then you might want to get one. Otherwise...
Most of the folks here are looking to find one of these or any number of similar Schwinns or other makes of vintage Balloon tire bikes at a bargain price at a yard sale or on e- bay where an origonal sells for less then the re- introduced version. There are notable diffrences between the two Black Phantom bikes. This kind of money $2000.00 is a lot to spend! Is far, far better spent if you want a nice bike to ride and enjoy and use daily for long rides that are a excellent outdoor health giving activity. You can get a old, collectable, classic in mint shape that is far more practical then this particular bike for less money. If you are set upon having a Phantom then look for a mint, origonal Phantom off of E- bay and go for that.

How old are you? how long have you been into vintage bicycles? Are you new in this? If so then please remember Jims advice. Many people think they can pick up a bike and re- sell it someplace and make money. Unfortunitly, doing that requires you to have been in the game ahwile and been around the block in this hobby. This is a difficult, tricky, and quirky game to play and many get burnt. If you pay $2000.00 for a reproduction, you will likely never get that much out of it ever again. Collectors watch out for reproductions that rarely ever go near what an origonal piece sells for. People can tell the diffrence between this reproduction and an origonal Black Phantom bike. Attend a Bicycle swap meet if you can.

The one I see for $2000.00 is dusty and has been gracing the window for some time now. The economy is not so hot right now and most people aren't buying $2000.00 re-produced bikes. These "re-pops" as we call them came out in 1995 too. The same basic balloon tire bike sells in the bike shop for lots less only without the period dressing up. You can get a multi-speed, more functional bike for less. Remember the song "Better Shop around" It applies here, I think.

   RE:REPRODUCTIONS:   Schwinn Black Phantom posted by JimW. on 12/29/2001 at 5:53:10 AM
If you really love fake Schwinns, and are a big fan of the movie "Men In Black", and are a millionaire, it's worth just about anything you feel like paying. If you're some sort of collector/dealer newbie, who'd like to use it as a stepping-stone to an entrepaneurial career avoid it like poison. There are so many ways you can screw up on this deal, it's not funny. If you pay $10 for it, you can't possibly lose, but that probably won't buy it. Let somebody else take the risk, if big bucks are required.

MOTORIZED BICYCLES:Whizzer Type Belt Sheave/Pulley posted by: Russ on 12/14/2001 at 3:50:15 PM
Looking for a source for the large rear wheel belt sheave used on the Whizzer and others. They are much too expensive ordered from Whizzer and are made cheaply so there should be another source somewhere. Any ideas on making a similar one from scratch?

   RE:MOTORIZED BICYCLES:Whizzer Type Belt Sheave/Pulley posted by JimW. on 12/18/2001 at 8:58:58 AM
You might check at http://www.mbikey.com/index.htm
MikeyBikey's motor kits use sheaves, also. They might have a better price on them.

The tricky part of making one yourself is the system for mounting the sheave to the spokes.Back in the day, some builders would take a rim the same diameter as the original,
and spot weld it to the edge of the original. This would be used as the sheave. Not a perfect match to the contour of a vee belt, but it worked.

I have never seen any others.
Mine is orange, front wheel drive with a 50cc pull start engine. It had drum brakes and has a latch in the middle so it can be seperated into two pieces for storage. The gas tank is also the headlamp housing.

   RE:MOTORIZED BICYCLES:Mead Ranger With A Motor? posted by JimW. on 12/4/2001 at 1:30:51 AM
That's a pretty good question. To the best of my knowledge, Mead didn't make motorbikes, but I suppose anything is possible. Mead mostly sold bikes via mail order, as opposed to most of the other makers, who sold through stores.

   RE:MOTORIZED BICYCLES:1950's Rabeneick Taxi Cyclemaster posted by JimW. on 11/14/2001 at 1:18:11 AM
Inspect the carburetor very closely. Most engine makers
buy their carburetors elsewhere. It's possible that your
engine's carburetor is shared with another, more common,
engine application. If you can find a maker's name on the
carb, you're halfway there. Most carb manufacturers have websites.

MOTORIZED BICYCLES:Coast To Coast Bike with Bike Bug Motor posted by: Sharon on 11/4/2001 at 3:40:11 AM

Information on the TAS Spitz, Sear's Free Spirit Aqua Bug Bike Bug Bicycle Engine.
Japanese manufactured to the mid-80s. Marketed under three different names: TAS Spitz, AquaBug Bike Bug, Sears Free Spirit. Two-cycle 28cc front fork mounted bicycle engine - 20 mph, 200 mpg.
Sears has one on display in the Sears Tower in Chicago - front door and center entrance.
I have rebuilt six of these engines. They are wonderfully delightful little engines to bike. I remember seeing them advertised in Popular Science Magazine at 12 years old - 40 years ago.
The manufacturer does have some parts available - however, not all. I have substituted several parts form hardware stores, lawn mower shops and motorcycle shops. I have also generated some better than original parts. In my rebuilding I have networked with several owners and have collected a very complete library of information on these engines plus first hand knowledge on repair.
Original Owners Manuals
Shop Repair Manuals
Part Lists
Technical Diagrams
Sources of Parts and Replacement and Original
List of Owners
I would sincerely appreciate your listing this information so it can be of benefit to other "Spitzers, Bike Buggers and Free Spiriters".

Hi there. I have a 1983 Bike Bug (not deluxe) with the standard transmission (engage/disengage manually with lever). It runs quite well, probably needs a new plug by now (ran it about a year ago in the street for 20 minutes). However, it needs the drive wheel, or one to be manufactured for it. I see a Mike Schneider on this page who cifes knowing how to replace the wheel for about a buck, but later asks for $20 for his plans. I'd be interested in selling this motor if the price is right. I've thought about replacing the wheel for my own use, but just can't find it, and don't appreciate the novelty as I once did. Make me an offer, and we'll arrange shipping, etc.

I would like to find out the value of my 1973 Bicycle motor. It is green and it says "I've got Chicken Power" on the side with a picture of a chicken riding a bicycle.

   RE:AGE / VALUE:1973 Orline Chicken Power Bicycle Motor posted by JimW. on 10/30/2001 at 4:17:18 AM
The Chicken Power bike motor was built by Ohlson and Rice, a maker of model aircraft engines. It is, basically, a large model aircraft engine with bicycle mounts added. They are not particularly valuable in a collectible sense, as compared to a Whizzer motor. A really nice, clean, well-running example might bring a hundred bucks, but probably less, from someone who was looking for something like that. I'm not sure if they are still being made, or not. Generally, if it's still being made, it's more desirable for people who want a functional bike motor, due to continued parts availability.

If the motor is in good working condition it has a value of between $50.00 to $100.00.

I have been looking to buy several of these to for their parts, to re construct a good working unit.

One of our businesses is a machine shop. We can mill parts from bar, but the cost is something the average person would underwrite.
