Old Guys Simplex moto-peddle bike

[indian22]

Curt an interesting property of using the included e-bike brake lever as a throttle for the gas engine is that when the "brake" lever throttle is used it isolates the electric hub motor, while leaving it powered up, just as it would when used as a brake control. This prevents the operation of the electric hub and the gas engine simultaneously, either accidentally or on purpose. This works for my purpose but if one wanted both motors to run concurrently & have a true all wheel drive it would be easy to wire around or just employ another throttle for the gas engine. It's my understanding, at this point, that the electric motor should remain powered up any time the bike is being powered either by another motor or by human power due to regeneration feed back from motor to batteries on brushless dc motors burning the Hall's out? Correct me if this isn't the case or elaboration is in order.

I've no doubt spent too much time dealing with the DC motor placement for the sidecar so I'll just keep it as simple as possible and hope it looks ok. Functionality over appearance & simplification again wins the day. I've some nice days forecast so I'm hoping this is last of the northern Clipper's edge effecting our weather. We missed the worst of it & that's for sure.

Though I'm slowly working two builds currently I've decided on my next project which will be a fresh take on.the V twin electric board bike. Long on looks and smooth while powered.

For those who are new to this forum the sidecar build will attach to this Simplex style board track bike.

I'm a fan of the early bikes & as a result my builds feature pedal start or kick start...no pull or electrics (though they function well) just simple and original concepts employed by the first manufacturers.

Got the Harley "pea shooter" back off loan yesterday...no damage incurred!

 

[indian22]

HD....

 

[indian22]

I just took the time to really look at both the Simplex and HD photos & spotted several details that I've neglected to correct or enhance on both bikes especially the Harley to achieve the period patina and look...the grips need leather wraps and the shiny aluminum toned down to match the engine case. Shifter lever lengthened & shaped, seat shock & spring might be eliminated etc. details...

Aren't they all a work in progress Rick? I am swapping out the 7075 41B13 sprocket with a Martin 41B13 steel sprocket on the final drive. Most likely make the reduction drive all steel like the originals.

[indian22]

Right you are Tom one day I might complete one, till then I'll continue to adjust...

I've been building my own steel reductions using go cart jack shaft sprockets welded end to end and bored out to accept oil-lite's to run on a 3/4" shaft, install zert's & keep them lubed. I recently replaced the oil-lites in the Simplex, but they probably had a thousand good miles left in them, but I had the chains off and decided to service the whole drive train while I was at it. I used roller bearings in aluminum housing for one reduction drive & ran with aluminum sprockets for awhile, but decided to go old school & it's worked pretty well so far on the HD and Simplex. I rather like the compact size of my steel drive set.

Using the term reduction drive for my drive isn't quite appropriate when referring to my 5 speed motor's primary to secondary drive sets as they are both the same tooth size, so no reduction is achieved, other than the slight step down from engine output to the idler set. Offset sprocket set might serve better as a terminology for my design. I continue to use aluminum final sprocket on the rear of most bikes, but have used steel in the past. No real preference, but the bright look of the aluminum on the HD is just too much and "aging it" like I did the motor case will probably suit me. The bright aluminum sprocket on the Simplex (with chrome wheels) doesn't bother me at all, so I'll lay the whole matter off to my personal taste ,or lack thereof, and deal with it, lol.

Still just having fun!

If you are going to be that fussy you better start looking for a oridgional motor? LOL. But I agree if the motor is aged, do the sprocket also.......but you are the only one to notice....Curt

 

[indian22]

I am a bit fussy as you say Curt, lol, but that's always been me. While my expectations might seem quite modest compared to others. You all have probably noted, my disdain at using much, if any paint, on my bikes. Just me, though I really do like other's work done up in beautiful color and finished to perfection. So you see I'm not against painted metal at all; just not into it personally.

The last original motor I had a couple of years ago was a HD knucklehead that had been completely gone through and I sold it for, what I thought was, an obscene profit & now the same engine would demand twice the price. I'm always looking, but what I call real deals & steals are scarce, Curt.

I'm really satisfied staying with engines that are readily available along with parts for all my builds. I don't see myself constructing bikes that I can't and probably shouldn't be riding daily because of the scarcity and therefore cost factors involved. I really like the simplicity of building tribute class bikes & I'll leave restoring classic museum bikes, even close replicas, to those who really just look at them mostly rather than ride them after a build, though some do ride occasionally. I really enjoy looking at these treasured bikes though & I'm glad that some of the original engines are being preserved and placed in true replica frames and on occasion even raced (Billy Lane promoted "sons of thunder" events etc.) but that's a hobby that I'll just watch and not participate in. Now I just build what I like & then ride and tinker on them.

Yep I agree, LOL the oridgonals are for guys with fat pockets, sad one day you could by them for $50, or $100 dollor bill, now unles you rob a bank, can’t afford one. But back then there were plenty to out and beat to death, rodding around, as they say the good old days...........Curt

 

[indian22]

Curt that's still my goal after building a bike...ride heck out of it. I tend to mostly ride the last one built for a few months to sort out any problems but still take the others out from time to time over that period. Including 2 pedal bikes it takes 8 days to "cycle" through them all,and it's just fun!

Spring's here so let's ride more.

Rick C.

 

[curtisfox]

For sure, sitting here in AZ, campground doing like Steve creative thinking, instead of staring. I have a big mess at home, after selling my lake place. During clean up I am going to get a simple motor bike going to ride. Then get back on my build, next winter. Tenable year this year for snow and cold, nothing new, just been a few years. Now rapid thaw and flooding in some parts. So when I get home will be all gone, and time to get busy.
Don’t know how quick my bu8ld will be because I am kind of fussy in a way also.LOL......Curt

 

[indian22]

Curt enjoy your time in the sun and the work at home will be there when you get there lol. Right now I'd rather be working on bikes but winter mess and deferred home projects added to wind and rain damage already this spring and my dance card is suddenly full. Mature excuses but I got to clean them up first! Then postponed family visits are scheduled as well, there and here...spring agenda is about full already.

Rick C.

 

[curtisfox]

Thanks, yes this may be our last trip out this way, sister in-law plans on moving north. So it would be more straight shot west then. Then the massive clean up, hole bunch of stuff from lake place no longer needed, hit a couple swap meets. Then I can get to my bikes this coming winter. Woo pie.

 

[indian22]

One of you guys shed some light on this old cruiser I found? Monark Silver King (part of the old battery co. in Chicago) the duplex tubes on the straddle and down tube are 'kinda unique I'm thinking. I've looked for a couple of hours but didn't see one on the internet that used duplex tubes on the down tube section of the frame. Definitely not a Schwinn Monarch and not a Danish Monark either. Kinda' cool...maybe from the 30's?

Hi Rick,
Not a clue but I will do an independent search. Boolean search algorithms are a pain.
Give ya a nickle if you post your photos in portrait mode.
Some detailed photos of the fork please too.
Tom from Rubicon

 

[Tom from Rubicon]

Hear ya go Rick,
The Monark Super Frame "Five Bar"
https://thecabe.com/forum/pages/monark_5-bar/
Interesting name, and I still want better photos of the fork.
Tom from Rubicon

 

[indian22]

Thanks Tom will do next I'm over at storage.

[curtisfox]

Way to go Tom, Kool info on them, I am kind off a Monark fan ........Curt
