True but the lightweight frame might not be up to the task. New Velorex frames are stronger than the 70s models. So some stiffening might need to be done too.

absolutely. the more i look at the velorex the more i consider my aesthetic objections to be bullsh it.

i used to paint cars for a living. you cannot show me a weird paint job that can intimidate me.

i see.

i thought the urals/dneprs were set up to require the rear wheels in line.

learning every day here.

nah i thought they were all like that

I kept up with Velorex USA for awhile and purchased a few pieces from them. I don't remember seeing anything like that. But it's been a long time since I visited them (online) so I don't know what's available now.

We're just gona disagree (and that's not a bad thing) about using the down tube as a mounting point.....by itself. I already admitted I knew nothing about sidecars......LOVED them at 16 but never rode/drove a rig until around 2010..........so I don't have a bank of knowledge. I put a LOT of metal in my subframe....but I was trying to spread the stress across it instead of the frame.....and I tend to over do things. (ya think?)

I haven't shown a closeup of my rear upper strut sub frame...........because it's embarrassingly thick. The bike could be broken in two and that sucker will still look like the day I bodged it. It runs from the swing arm spindle to the shock mount.......then a tang to the rear for the mount. I love it but it is embarrassing.

I have a work background that includes cast in place concrete.....I learned the hard way you can never put to much bracing on a form, but you certainly can put too little.

That's the BEST laugh I've had in YEARS!!!!!!!! I'm still laughing

You look at some and all you can think is "WHY????????" Knowing all along someone else stepped back and said "DAAAAAAAAAAAMMMMMMNNNNN"

I'll check with him......but he could have let it go by now......he's gota few wrenches in his family.

"In the pics posted by Kevin show the front upper strut is mounted to the frame of the bike. It's not like your design."

Mounted to the frame.......but also connected to the lower section of the chair's frame?........so I'm gona call that not just the down tube by itself.

Mines mounted to the frame (down tube) too. In two places.



At the front engine mount



And up at the headstock

EDIT: This was a mock up.......there's a loose plate missing (and yes w/longer bolts) that backs up the fixed plate shown.

Thank you.

It got weird when I updated the swingarm ( from Velorex USA) . It used a trailer tire so my lowers had to move. I gave up on that idea and went back to the stock set up.....but with a new shock from Hagon.....haven't looked back and even removed those connection points. (the uppers)

This was my final go at it........first time around I had this cow catcher thing going on......now that was a BAD (or at least ugly) idea.

Don wanted me to do it all in tube but I don't have those skills..( I wish I could have) ...I'm a square

That's nice.........what are you going to mount it on and can we expect a video of it on the road tomorrow?

oops.......wasn't paying attention.....late October delivery?

There's a Jawa in here somewhere.

ill be interested to see how you mount it on the BSA

what the hell is that?

kevin….I was wrong about what state that fellow lives in…..he’s in PA not Ohio but the only times I’ve been around him was in Ohio….. my mistake.

He still has his chair but doesn’t want to let it go…..and I understand that completely. Didn’t hurt to ask though.

The search continues……….

Pureblood……that A10 is beautiful. I hope you will keep us updated on the chair attachment……more photos the better!!!!

That’s going to be a really nice combo…..IMO the best BSA for a rig.

ah bummer

still, theres lots of options.

This was a mock up but........I missed the fact that I needed to "sandwich" the headstock. It never made it to the road without this backing plate. Had to use a longer bolt and.......I don't remember what you call that eye bolt the strut connects to......but I needed a longer one of those too.



I'm going to show the upper rear strut's sub frame.........talk about overkill. I tried but couldn't find a camera angle where you couldn't tell how thick it is. Connected at the shock with a grade 8 and a grade 8 through the swingarm spindle. Ridged connection is an understatement.





Since the bike has been down ( waiting on an engine from Ed V) I added a couple of upgrades?

8" TLS front brake....




And.........a BSA oil filter ( Idea stolen from George Walker of Moto Giro USA fame)





Still trying to figure out how I want to finish mounting it.

I miss my rig.......

damn

id be all over this if it wasnt on the wrong side of the country

Hate to hear the seller let you down……Ukraine???? Goodness not sure I’d feel comfortable about that deal.

Good luck

excellent

Would it not fit in the same location as it does on the WDB40?

Alan.....show me please. Right now it's just mocked up......and could be moved. I do like the fact that George's idea is easy to get to.

Alan……the only info I can find on that set up is a diagram showing the filter laying horizontal (owners manual). But it doesn’t show how/where it’s mounted. The photo I vaguely remember seeing showed it in plain view????

Remember there’s a chair on the other side so I don’t want it over there.

This is for my sidecar tug that is still sitting waiting on an engine to come back from EdV. I made the mistake of telling him it was going to be a spare engine so maybe that’s why it’s taking a while……I need to send him a reminder that I’m still alive and now that engine is going to be the primary.

The matching number engine has had too many “skilled” hands on it and is a work of art……so I just have it on the shelf on a stand so I can admire it. Mr John Healy, EdV and Don Roe have all done some work on it. The Brimfield Engine.

If you can show me how it was done on that B40 I’d be more than willing to explore that option.

Gordon, is that Darryl's old bike? If so, dang, it does have some history to it.

Think I may even still have some parts shed from it...

Yes sir!!!!!! That’s the one. Do you ever hear from him?

I’ve done a LOT of miles on that thing…..and if I live long enough I’ll do a lot more.
That bikes been ridden from North Wilkesboro to Coudersport Pa and back twice!
Did around 1600 miles as a loaner to Brimfield and has made a couple of trips to TWOS…..but that’s an easy 500+ mile round trip.

(Of course I only ride in first gear and not really get anywhere.)

Hi Gordon,

please see below, the body is painted green here and the WD frames had a bracket welded to the frame, but you could possibly rig something to suit. The B40 has the carb over to the same side as the oil filter so clearence shouldn't pose an issue.

note between crank case and carb.

Thank you Alan…….I’ll look into that location👍
