Ancient Motorcycle Technology that's actually BRILLIANT

[@Mr9Guns]

Vincent was incredibly far ahead for it's time. The use of the engine as a stressed member wouldn't become commonplace on sports bikes until the 1970's. The speed records set by Vincent lasted decades. A bike from the 40s with the engine as the stressed member, huge use of aluminum alloys and going to a shorter stroke engine with wider bore like many modern bikes for peak horsepower. Not to mention it's one of the best looking bikes ever made!

Here in the UK, back in the seventies and early eighties, there was an articulating sidecar called a sidewinder. It was just a frame and wheel, and was designed to get around the licensing laws at the time. Before you passed your test, you were limited to 250cc, but if you had a sidecar attached, there was no limit, so people used to bolt these on and get away with riding a much bigger bike. It didn't take long before they changed the law and banned them.

[@warmstrong5612]

Those Roughrider grips are just like the sprung saddle but for your hands. Early bikes had lousy front suspension that would cause wrist fatigue, they weren't for "tucking in". Drop bars were a thing back then.

[@alternator7893]

I have a sprung saddle on my hardtail, which is also my daily rider. They are still very popular today, specially on choppers. I don’t consider sprung saddles real suspension tho. They do make the ride more comfortable but since they are un-dampened, going over a large bump can send you flying over the handlebars.

[@seanseoltoir]

My FLHPI has an air suspension on the "police seat", so I guess that is kind of a "sprung saddle" also... Most comfortable motorcycle seat that I've ever had...

[@senatorjosephmccarthy2720]

I didn't know that. I do suspect going over a medium bump with a contour seat and a hard tail like I had for a short time, can likely send a person over to a wheel chair if carried on for too many weeks. So a spring seat would be a great difference. Except when going over the bars.

[@ludditeneaderthal]

Depends on the seat style. Those "pair of springs" upholstered tractor seats, yeah. The old school (until the early 80s) harley "pogo stick" seats, properly adjusted, not so much. The tractor seat can be upgraded to the mini coilover shocks used in bicycles these days, and actually have a genuinely oil dampened travel.

[@carlosoruna7174]

Umm my harris frame, bimota seat, honda 750 with a marzocchi front and rear suspension also hates large bumps. Hard on the wrists with tomaselli clip ons. Lol

[@ludditeneaderthal]

@Carlos Oruna the complaint isn't so much "harsh ride" as "undampened spring porpoising". More a diving board than structural beam response to a bump. In the same way, those "springer" front forks bound (dive) and rebound (leap) in response to bumps, or braking. The factory springers of "the golden age" used friction dampening, the modern ones use that ugly front mounted shock absorber to mitigate such unnerving antics of the front suspension, lol

Urals have a driven third wheel, which is HUGELY advantageous on the rough terrain they were designed for. The fact that its a rigid, self standing unit with two wheels pushing, is far more suitable for purpose than a flex type unit. Flex is very desirable on a faster roadbike, I have to admit.

[@TerraMagnus]

BMW really should go back to offering sidecars as a factory option. Particularly one with 2WD like a Ural but with more of the BMW experience.

[@madbrowndog4887]

+1 for Urals being made for Russian conditions. My first bike was a Voskhod 175, the Ural's baby brother. Heavy, underpowered, almost unbreakable. All purpose tar/mud/snow tread on the tyres. Interchangeable front and rear wheels, which could be swapped in minutes, as the fully enclosed chain and drive sprockets stayed on the frame. IIRC this was to allow a spare wheel to be carried on a sidecar. Genius of a different kind.

i can't say for sure about the ural mototcycles, but we had a family friend who had a side car attached on his bike, the bike itself is pretty light but he needed to the sidecar for a family member.thr bike needed to regularly go on some serious off roads.the sidecar that was first connected was a articulating one ,but he said that it helped on the road but said on bad or tricky offroad parts the articulation just made it much more difficult and unstable for him to traverse.the second sidecar was fixed and he said that offroad it was much more stable and controllable and the onroad performance was acceptable.he was not a elderly man at that time but also not very young.urals are kind of seriois offroad bike so i think thats why thry did not have a articulating sidecar.also ural is a lifestyle like company that sells a certain piece of history sort of bike so i can see why they did not deviate fron the design much.sorry my english is kinda bad.

i think it would be pretty easy to include a tilting mechanism with 2wd because you just need to cv (probably rezepppa) joints and the bearings for the axle to get decent tilt angle.also ural was a war time motorcycle,a fixed sidecar would provide the ability to stand by itself without the rider having to control or support it would probably be very beneficial either in war or offroad.he would have also liked it because he would not have to use his core muscles much because of growing old.sorry for another wall of text,i just thought about this after writing the firat comment.

[@vanceblosser2155]

@@russcole5685 Ural has announced that for 2023 they are changing from cardan joints to CV joints on the driveshaft, stated reasons are for reduced maintenance and extended life. I doubt they have plans to do a flexi style sidecar. Production at the factory was 300,000 bikes per year before the Soviet government fell, the current demand is somewhere near 3,000 bikes per year. Obviously the money available for development and changes is very limited now and their focus has been on improving reliability and I can say that they have made immense strides in that area. I've owned 3 of them, the first a 1994 which was fun but you carried a lot of spare parts, then a 2000 which was much better but still had issues. The last one which I still drive is a 2004 and it's mostly gas and go with scheduled maintenance such as oil changes, valve adjustments etc. And at the rallys owners of the newer ones say they are much better. A side note, all of my bikes were 1 wheel drive, I don't offroad and so didn't need the expense of the 2wd system.

The post spring combo on Harleys was a bit more elaborate. You could get heavier and lighter springs to adjust load. They were short so they could be stacked in various combos to give a progressive spring rate. The treaded shaft had an adjustable collar to adjust preload. Seat post had about 3 inches of travel. I used a zip tie to check travel when I bounced my arse. You want almost full travel, but not to bottom out on the frame. This was probably the most neglected part of prior restorations. I had to re-do every bike I got. I even had one bike where the springs were disintegrated and breaking apart. You can still but the springs from aftermarket sources.

I think the main advantage of the sprung saddle was missed - it enables long hours in the saddle due to the fact that the pressure points are constantly varying, allowing blood flow to all regions of your butt and preventing soreness resulting from a stationary relationship between butt and saddle. Very few fixed saddles are well designed; they feel great in the showroom but not after three or more hours on the road. My 1974 BMW R90S (silver smoke) was an exception. I could ride 600 mile days on that and still walk normally when I got off!

Have to echo Mr9Guns, from my reading (esp Phil Irvings's "Modern Motorcycle Engineering" which I bought in 70's), that frame member you saw in the video of disassembly of Vincent was the stressed oil tank. The weight of the whole bike was very low, around I think 465lbs, and it had a centrifugal clutch which in theory would grip better at high rpm (in practice was notorious for slipping). The cams were high in the crank case and the pushrods actuated the valves with forks from under the springs making the pushrods short and lighter reducing inertial loads and allowing higher revs. The rear suspension pivoted off the gearbox, and loads from the shock went into the oil tank. Cycle World tested a 50's Vincent in the 70's and even with slipping clutch did a 1/4 mile in the 12's! I may have seen one in the 50's outside Montreal...but it might just be imaginary wish fulfillment, of a kid...

[@gunfighterzero]

You can easily spend 23k on a ural now. Sidecar alignment on a rigid rig is crucial. if it's out of line it can pull you to one side, wear tires unevenly and generally be more unsafe. There is nothing simple about an articulated rig, it would really over complicate a ural due to its 2WD system. That system does let you lean more but still limits how much and all those moving parts have to be kept in precise adjustment since you now have 6 points of articulation. it also makes the rig overall much wider.. I'll stick to my regular ural

[@alandavies55]

As a Ural rider since the 80s I agree completely. Some years ago Jawa sold an outfit with a rubber bush linked to the rear wheel spindle that was supposed to improve stability. All it did was to knock out the wheel bearings and swing arm bushes quicker, and it was soon abandoned.

Regarding the Flexi-Sidecar, I know that a standard sidecar motorcycle must be steered like a car not a motorcycle. This is a very important distinction between the two platforms. It looks like the Flexi-Sidecar would allow you to ride the motorcycle as a motorcycle with the sidecar, which again is a key difference.

[@bakters]

" *a standard sidecar motorcycle must be steered like a car not a motorcycle* " The main advantage is that it's inherently stable. One, or even all three wheels can lose traction and you won't fall over. It's inherently stable. From what we've seen in the video, this folding sidecar seems like a very bad idea.

[@MrSaemichlaus]

@@bakters I also think keeping the balance of the bike under normal circumstances is not trivial. Any weight shift of the weight in the sidecar (at a stand still as well as in motion) must have affected the balance and the lean of the whole bike and sidecar. I imagine it would be a matter of discipline of the passenger or just limiting the use of the sidecar to cargo only (which would also need to have its mass pretty much centered). The footage shown at 06:00 seems to show a passenger sidecar where the passenger is sitting in a low, recumbent position, thus reducing the potential weight shift as well as its effect on balance. Furthermore, the rider at the controls would have to rely on countersteering alone to steer and balance the bike, because shifting his weight would have a lesser effect due to the additional inertial mass of the sidecar.

The leaning sidecar seems like a cool idea, but it doesn't work on winter and makes the sidecar frame more fragile. Also adding a drive to the sidecar wheel is basically impossible to make in leaning form, when it needs to last on rugged terrain. And, rigid frame sidecar stands upright on it's own. Leaning frame needs a stand to hold upright. Yes it can hold somewhat on a smooth level surface, but Ural is not designed for such surface. It's an off-road/adventure sidecar vehicle designed to go almost anywhere in any possible weather. Leaning joints would create unnecessary failure points into the design, and lower the load capacity.

I've done a lot of sidecar riding (driving?) always with a rigid set-up and it really isn't a problem once you realise that, like any other two track vehicle, you need to turn the handlebars to turn it. The reason a leaning or other flexible attachment hasn't become popular is because it's unnecessary. The leaning doesn't move the CoG enough to make much difference. To make the outfit turn faster the whole thing needs to be lower and that's only done on racing machines. At one time I used to ride an old ex-works 1949 BSA trials outfit - often on my own. In fact, I used to lift the chair on right-handers (LH fitted - I'm British) and ride it like a solo :) I also used to ride racing pedal trikes (like a normal bike just with 2 back wheels) and got great amusement when bike riders tried to ride it and ended up in the ditch because the tried to lean it rather than steer it.

I haven't had the opportunity to ride a side car rig much. I got licensed before the pandemic and haven't been able to afford my own. But, it's not just that it's unnecessary, but it also gives you an unnecessary point of failure to worry about. Back when this technology was still being made, the roads weren't as good and you could be going a bit faster over rougher terrain. These days though, you probably wouldn't be. I'd expect to get a differential to drive the side care wheel when turning well before we'll see the flexible side car reappear.

👍 Wouldnt it have been lifting on left handers? Side car would have to be on the inside of the corner

The articulated sidecar is a brilliant concept for riding, but it is maintenance intense and the linkage breaking will lead to disaster. The shock common in motorcycles will destroy any connections the looser they are, the faster they fail.

I would so love a flexible side- car on my Ural
