MOTORIZED BICYCLES:   Raleigh RM 5 Supermatic 1963? posted by: Lane on 3/6/2004 at 11:39:41 AM
Greetings! I am going to try to fix up this moped. Has anyone had experience or parts for this model. It has the leading link front fork and the rubber bands have broken, any thoughts on replacement options? Thanks, Lane

Not much help on parts but as a kid I found an old beater and man I have to tell you I loved that moped. Real cool looking and it was fast compared to all the Puch's that were roaming around back then. Have fun that is a great bike. Geo

Think I've got your wiring diagram tucked away in the files. I've got a 1977 Puch Maxi. I can look for it and copy it for you if you still need it.

MOTORIZED BICYCLES:   New Wyman Motor Bicycle posted by: Rif Addams on 2/8/2004 at 5:30:45 PM
Hey all,
My new engine arrived on Thursday. It's one of the GT 48 ("Spit-Fire")chain driven units.
I am scrambling to get the new replica together for finishing the film work for Ron Rennie- the film maker involved in the Wyman project. He wants to have the extra footage edited with the shots we took along the way this summer, along with the musical scores, and the narration by this coming summer.
I've gathered the majority of the parts for the new bike and have been working feverishly all weekend stripping the paint from the 1967 Schwinn Varsity frame, grinding, filing, and sanding smooth the cable guides (brazed on).
I hope to have my gusseting plate cut and welded in place by this evening, and at least one primer coat sprayed.
The 1964 Bendix r.b. coaster brake hub is out being re-drilled for the .105" spokes and I should have the STEEL 27" X 1 1/4" rims re-drilled and painted this coming week. I still haven't found the appropriate front hub, but will continue to dig through my parts in search of this elusive piece.
I have the handlebars sets which I hope to begin (and finish) modifying next weekend. In looking at the engine mounted in the frame, I may in fact, have to slightly dogleg the the crank on one side and bow it on the other. No big whoop there, easy as pie.
I have the tail lamp and battery, and possibly the housing for a headlamp. I still have the battery from the other bike. Bob Johnson will be constructing a new hanging box tank, which shouldn't give us any problems. The reason we had trouble with the other one is that it had to be cut down at the last minute to clear the Whizzer engine, which itself was a last minute change. This caused a structural problem at the seams. Building one from scratch to the dimensions needed will give us a solid tank. without modification it should be great. Bob will also be fabricating a new scaled down battery box for our lighting requirements.
I've got just about everything, but I still need to aquire:
front hub, spokes (and have the wheels built), rear rack, and most importantly a saddle like the one we used on the Mead; a tail lamp / license plate mounting bracket, headlamp mounting bracket, bulb horn, bell, speedometer, and...?
In any case it's in full swing now, yet time is tight.
BUT- this may all change as I came across an old off-brand English Roadster with 28" wheels (complete rider) that an aquaintance picked up for free. I'm hoping that he will be willing to sell it for ultra cheap and therefore save me some work. It's even got the front rod brake! It would look a lot closer to both the original California motor bicycle AND the Mead Whizzer, thereby giving us an easier job of 'blending' the footage...
I would still have to re-drill the rim hoops, and front hub, and have them re-laced (with the Bendix hub out back)

I will have to appologize for any delay in the website story, but Ron needs this 'new' or 'filler' footage by this summer in order to send it to various indy film festivals and to shop it around to some PBS stations, or whatever else he has in mind.
I will write as I find time and inspiration, so please be patient and check the site occasionally.

Count spokes on the English bike--bet the bendix will not fir those rims---sam

          RE:RE:MOTORIZED BICYCLES: New Wyman Motor Bicycle posted by Rif on 2/10/2004 at 1:26:55 AM
I bet your right! Boy that's an easy one and I almost missed it...
Thanks Sam,

          RE:RE:MOTORIZED BICYCLES:   New Wyman Motor Bicycle posted by Peetie on 2/24/2004 at 2:55:45 PM
You may find the SF engine fits perfectly in frame, but check for crank to engine clearance.
The good news is, wheels are probably 40h which makes the 5 hole rear sprocket almost a bolt-on.
If you have any questions, just buzz me.

          RE:MOTORIZED BICYCLES:   New Wyman Motor Bicycle posted by Sandy Evensen on 8/7/2004 at 11:04:50 AM
Hay Rif, I have a 1974 Schwinn Varsity that I motorized with a 2 Hp Brigs and Stratton upright, I fashioned it after the 1903 Californian and ride it almost every day, I cut the PTO shaft off the motor and attached the V belt drive pulley inside the cut down fly wheel, witch keeps it narrow enough for pedaling with a standard crank, T built the tank out of 2x2 square tubing and it hangs under the frame,
I built a front fork brace like the old racers had to beef up the front end. I use a friction drive on mine with a jack shaft to drive the wheel, Every thing is bolt on as I did not want to weld on the frame, If you are interested let me know and I will send you some pic's...Sandy...

MOTORIZED BICYCLES:   electronic ignition for TAS, BUG, SEARS, etc 2 cycle motors posted by: john martin on 2/5/2004 at 3:44:36 AM
Thanks to the response for this new system. I can now reduce the price to $32.00 plus $2.95 S&H for regular U.S. mail delivery or $4.95 for priority. With the kit, you get the electronic ignition, a new spark plug, parts to install and complete instructions. At this price, why mess with points and condenser?
Contact me at:

          RE:MOTORIZED BICYCLES:   What Model posted by edgarecks on 2/6/2004 at 4:31:54 PM
I put mine on an old Schwinn Varsity/Continental type frame. Here's a pic: http://groups.msn.com/KustomCruisers/customschwinns.msnw?action=ShowPhoto&PhotoID=161
The straight bar frame works best with the gas tank, but it could be mounted behind the seat on a cruiser frame.

          RE:MOTORIZED BICYCLES:   What Model posted by Larry Wlos on 2/15/2004 at 9:07:44 PM
I mounted a MX5 in a 1950 Schwinn DX 24in. frame.It took a little reworking but it made a real nice motor bike.

MOTORIZED BICYCLES:   Braking problems posted by: Alan on 1/9/2004 at 9:49:04 PM
I am hoping to get some advise on what I can do to solve a problem I am running into on my chopper bike. I am running a motor on it and have no pedals since it is a pull start. I have a 24x3.45 rear tire on the back and cannot use a rim brake and the set up is for a coaster brake. How or what can I make to press or pull to engage the rear sprocket to trigger the brake? Any help would be appreciated. If a picture would help, I have some pics of the rear end to help with any ideas.



          RE:MOTORIZED BICYCLES:   Braking problems posted by sam on 1/12/2004 at 4:30:22 AM
Very simple ,braze an attachment for a spring on the top of the rear fork.Run a spring back toward the sprocket.Attach the end of the spring to a small lingth of chain.run the chain around the sprocket.Where the chain ends just infront of the sprocket to the bottom of the fork attach a rod linkage and run it to the front of the bike.Add a foot brake pedal and attach the linkage.When you step on the brake it will pull the chain forward and set the coaster brake.The spring will pull the chain back when you release your foot and release the brake.----sam

          RE:RE:MOTORIZED BICYCLES:   Braking problems posted by Alan on 1/13/2004 at 10:57:52 PM
Thanks for the advise. I figured that out later that night and it worked great. I used the rear coaster hub and took the old crank and cut off one side and mounted a small sprocket on the crank and put it back onto the bike. I then took a chain and ran it from the rear sprocket to the new small sprocket and made a suicide handle coming up from the sprocket. All I do is pull back on the handle and it engages the brake. i installed a spring on the handle to the frame so the handle would return to the upright position and stay locked up. Thanks again for the advice.

MOTORIZED BICYCLES:   TAS motors posted by: john martin on 1/2/2004 at 2:59:45 AM
Having throuble with the points and condenser on you TAS, Bike Bug or Sears motor? I have an electronic ignition that installs in about 10 minutes. No external changes and it eliminates the need for those old parts. Also the spark is hotter.
If interested:

John - That is great news. How in the world did you get the right one to work?????? Folks I spoke with said it would be not possible. Glad you have proved them wrong. Points & condensor were going to be the death bell for those great little motors.

John is my new Hero.

MOTORIZED BICYCLES:   Weed Wacker power posted by: Kim on 12/11/2003 at 2:35:06 PM
I have an old cruiser frame and a working 2 cycle weed wacker motor. I've heard these motors are good for powering a bicycle.
Would I use a friction wheel or a chain?
I'd like to go with a chain and use the weed wacker's clutch.

What do your think?

          RE:MOTORIZED BICYCLES:   Weed Wacker power posted by sam on 12/12/2003 at 3:26:08 PM
The ones I'v seen took the clutch off and went friction wheel.Very simple set-up.They just mounted the motor on a U shaped metal bracket with friction wheel on shaft and push in barring on other side.Used long springs to hold it to wheel and lever to disingage wheel.---sam

MOTORIZED BICYCLES:   Looking for information and identification posted by: James Marshall on 12/5/2003 at 9:58:16 AM
Greetings all, I have recently acquired an American Schwinn Bendix Automatic 2-speed Model B Typhoon -- with a Zundapp two-stroke motor mounted on the front fender between the forks and driving the front wheel via belt drive. The serial number of the bike escapes me at this moment but starts with a "C" and the Zundapp motor , a 49cc powerplant is dated 1954. The machine seems to be missing some small cosmetic device that attached to the left front fork leg via three screws but otherwise seems to be very complete. Tires are shot but rims are perfect. Was there ever such a beast built by Am. Schwinn? This looks very factory but I don't know where to find any information on it. Did Am. Schwinn and Zundapp ( or possibly the Berliner Corp. ) colaborate on a motorized bike design in the 50's? Any information or ideas would be greatly appreciated. Thanks in advance,
james marshall

          RE:MOTORIZED BICYCLES:   Looking for information and identification posted by sam on 12/9/2003 at 4:08:51 AM
James If it's any help the 2-speed auto from bendix came out around 1957.Your motor is 54,right? Schwinn did something with whizzer but not sure what.

          RE:RE:MOTORIZED BICYCLES: Looking for information and identification posted by Rif on 1/1/2004 at 7:38:52 PM
Schwinn did go into a sort of "partnership" with Whizzer in that they manufactured frames for Whizzer for a while.
These frames can be identified by the 'WZ' designation on the I.D. number.
According to my info 1947 was the first year of the Schwinn built Whizzer bike (wz507, later designated as S4); this was a variation of the cantilever frame patented in 1937.
This fame had heavier welds, used .105" spokes, The rear frame stays (seat and chain) were dimpled to provide better belt clearance. The Knee Action spring fork was used with a heavier spring, a front brake, and a welded on brake arm anchor point was used on the left chain stay connected to the brake arm by a strut.
In august of 1948 a 24" wheel version (S10) was offered. Both used S2 tubular rims.

Hope this helps...

          RE:MOTORIZED BICYCLES:   Looking for information and identification posted by Becky on 5/19/2004 at 12:09:30 PM
We were given a gas motorized bicycle. It has pedals to start it. It has brakes on the front handle bars we were told it is a 1957 German bike. If this is so what would that be worth if it still runs?
