Have the same bike, they are beautiful. Are you having any problems with front fender? or have you reinforced it?

The "L" bracket on mine was poorly riveted and ready to fail. After reading some horror stories, I just removed it. I was bummed as it really added to the overall look of the bike. I cut out the rear fender with a pair of snips. It was a butcher job but as I had not allowed for enough room for the chain to bounce around, the chain actually smoothed it out. Just realized that, lol and I highly don't recommend doing it that way. I am going to put springer forks on her soon so as to (aside from the obvious, bump and vibration reduction) try and even out the ascetics of front and rear.

SGT: nice lookin' bike. good, fat welds on that frame.
How do you like the Limited kit? besides the premium hardware (double brake-pull lever, chromed/dished sprocket) i really dig having wrist-pin bushings. revs out higher.

Dan is right about the fender. you really need to ad an extra, heavy gauge "L" bracket to the front fender (for total of two), or toss it out. There have been quite a few guys' factory tabs breaking. the front of the fender drops down, catches the tread, follows the tire, fender support rods follow up the the forks and LOCKS front wheel up, sending sgtnorthcutt over the handlebars. we dont want that.

I too have the same bike. I simply dremeled the rear fender. And I reinforced the front fender with fiberglass from underneath. VERY rigid now. I may have the paint to match the frame coming. It's a testors paint, so if you want to take it a bit further let me know. I'll post the results of my paint match. As you can see with my current paint, it's a bit off.

"I reinforced the front fender with fiberglass from underneath." very cool, bet it has not a bit of rattle? Did you use a solid piece Moto?

Hi... I can't see the engine mount very well.

Did you add a center bracket at the bottom to help support the motor? I'm doing a lot of research on how to support the motor from the bottom..

It would be great if you could post a closer detail view.

I just used a fiberglass repair kit from the auto parts store. Had a few yards of the mat material. Very messy, but no rattles! I've used glass in the past on wooden boat repairs. So I knew that was the way to go. NOW if I could weld, and I'm going to learn that next year.....

I used the standard mount for the seat tube, and the boy go fast kit for the front. The motor doesn't need any more support than that. It's only 12 pounds.

If you are referring to my photos... I can't speak for the original poster.

I keep coming back to this thread to view Motoschwinn's Point Beach set up. I tend to study on things for long periods of time and then create some preliminary sketches to visualize on paper or screen what I'm thinking. The thought of creating a motorized bike that harkens back to the 1910 era of board racers and motorcycles intrigues me.

Today one WalMart near me finally got some Point Beach bikes in, both in boys and girls frames. I've only seen them up close as girls bikes. So I ran to the hardware department and got a measuring tape and began to take some measurements and see how it would lend itself to creating a vintage bike replica. I figure I'd have to cut frame elements off it and extend the frame foreward 4 to 6 inches and install pyrimid springer's to get the look I'm after. The Point Beach is reduced now to $124 bucks from $160. I'm still left wondering if I could buy several old bikes for $5 bucks each at flea markets and build from them. This time of year they are all but giving them away. The springers would likely be where I'd have to spend some money, beside the motor kit.

But what I came up with was this sketch.



The fuel tank would be made of sheet metal to house a plastic string trimmer
fuel tank of some kind. The CDI ignition would be dressed up with some kind of ancient looking aluminum casting to lend to the vintage appearance.
I didn't render a rear wheel stand yet, or color the aluminum rims either.
I'm sure I'd remove the two smaller top tubes at the seat post to the frame head and just rely on the top frame tube.

But the Cargo Bike and the Vintage Cycle replica bike would complete my stable for now.

Awhile back we were talking about 2cycle motor kits with round cylinder heads and square heads. Which kit "makes" offer the round heads ?

You know if a person wanted a slightly different looking motor, this Russian made motor looks SO cool. Tear drop head.... There are 25 left in the states, and $5000 will buy them. $200 each.. I can do 3 or 4.... anyone want to kick in on them?


But back to your changes, I think you are really killing the nice lines of the bike. To me the engine sits well and fills the bike just right. I think a custom tank inside the frame, and a springer is all it needs. Of course vintage touches, and maybe a really nice vintage color would be the icing on the cake. I've been thinking about having my stripped, and painting it one of those weird colors VW used in the early 60's, with the rims painted to match... White tires.

Wow, I like that old looking motor !

I may not wind up using a Point Beach for the frame source after all. There are a few other frames laying around in an old bicycle barn down the road that may better lend themselves to welding. But the sketch is close to the look I'm wanting. That Russian motor could be a much better complement for it than a more modern looking Boygofast. It would be more in keeping with the vintage look. Like this 1912 Norton below.

I don't see a carb on the Russian motor nor the chain and sprocket stuff that would be in a complete kit. I'm left wondering if this motor has a rotary valve since the carb isn't visable. I do see a mushroom shaped form under the exhaust pipe at the cylinder though. But the look of the motor would be just what I'd want. I wonder if the bottom end has bearings or is just bushings on both ends of the con rod ?

Have you found a source for paintable springer front end ?

The tank I rendered is really basic....just something to put there to visualize with. Even the lettering I stuck on it was not a font I would choose for the final. I'd go to some vintage sites to do more study on the tank. The look of the tank, motor and foreward stretched frame would do it for my project.

I believe there are some vintage paint color producers out there. I know VW made a
loud Saturn Yellow, and a phosphoresent silver called Diamond Siber Metalic. (imagine the look of the silver of the Hindernberg) The Germans do have an eye for color that's a bit different than what's mainstream here. I once saw this VW that was an odd Metalic Teal.....called Marithon Metalic Blue. Kinda like a deep teal aquamarine metalic. Odd to say the least. But, bright high chroma colors look best on small items like VW cars. So they would lend themselves well to motorized bikes.

What's the URL for the Russian motor ? I'd like to read and see what they say
about it, it's stated displacement, other components, shipping cost, etc.

As far as the front fender, I have decided to drill a small hole in the fender just behind the fork. Then I will run a piece of tensioned wired from the front to the back the of the fork through fender attached to the same bolt. Then if the L bracket brakes, it will stay in place via the tensioned wire.

the reason I got into MBs was to build a boardtrack racer type bike! If only someone made boardtrack tanks for these MBs and mass produced them. hmmm.

It means I was injured in combat in Operation Iraqi Freedom 2.2, and that my life is filled with bureaucratic nonsense from dealing with the Veterans Administration.
I hear that. Our company landed a 4 million dollar contract with the VA, lot's of well let's say headbanging.

Anyway I was just curious,

Thanks!
