No, the counterweight STOPS the rear deraileur from jumping. Before the counterweight the QV would 'ghost shift' on every bump and in hard turns. Rob (QV#18)
great idea to show us all how the QV works .... u would think the manufacturer would have videos like that .... but then maybe more people would wanna buy one and the waiting time would be two years
Thanks for thi interesting video. I know what you mean with it is feeling funny. It is actually like a car. But now only that section is tilting. Also the problem with the jumping chain is something I know. But it is not that often. And in my highest gear my chain is driven off the casette. But I going to fix this. I like too see this view because it really tells what it does. In special when you slow it down. Thanks again for this informative video.
That was interesting Saukki, well done. I had the 'two wheel drive' system on my conventional trike. I may be wrong but I hear that the time when both axles are being driven is less than you'd imagine - it's extremely difficult to stay in a perfectly straight line and of course, the road imperfections will add to this. I used to find the strange feeling you describe would be more noticeable at slow speeds.
The advantage of having two driven wheels is more that if one wheel loses grip (for example is on grass), a QuattroVelo will still just go because the other wheel has grip. I only gut "stuck" twice, both times on hills so steep that all cyclists were walking. In one case, in fact, I could barely stand there on my cycling shoes. It was too slippery.
This is really really interesting to see. I've been fascinated with the QV drivetrain system ever since you showed images of it a long time ago. The differential is intriguing and the cassette in the middle is strangely satisfying. I don't know if the new quest is different, but the qv seems better built and potentially easier to work on than your old quest. I'm actually looking forward to maintenance videos as they are so different to the bicycles I work on. Particularly cassette swap in the distant future.
I’m affraid the maintanence is more difficult with the Quattro compared to a Quest. But so far only maintenance I’ve done is to lubricate the chain. And that is more cumbersome than with a Quest. But we will se how it is when I have to do the first big maintenance. (Hopefully sometime in distant future. Very far 😂)
@@TheVelomobileChannel, that's funny. For me lubricating the chain of my QV is super easy 🙂 I use an old plastic pot, just high enough (about 15 cm) to get the rear wheels of the ground if I put it a bit in front of one of the wheels (on that point the bottom is strong enough since the wheel well joins the bottom there). I take the lid off the box around the rear axle. Then it's just letting the oil drip on the chain while you make it move backwards by pulling the wheel (which spins freely, since it's lifted off the ground by that pot). 1-2 minutes work 😉 The Mango with 2 chains was more work.
I'm sorry to hear it's even worse than the quest! I thought it would be unlikely they would involve so many tools and such complex procedures when they had the chance to design the QV from the ground up. One of the most interesting things about velomobiles in general is how each company has their own imperfect solutions for shifting, suspension etc. Unlike upright bicycles which are extremely refined, it seems like there is a lot of improvements to be made in the future to the drivetrain in particular. I could imagine in ten years time the system will be very different. Also a lot of improvements to the maintenance and access to parts can be made I think.
Yeah, you can ride the rumble strip between the wheels, so it's no problem. Also if you hit the rumble strip, theres another rear wheel which is not on the rumble strip giving lateral stability to the velomobile. But on the other hand the Quatrevelo rear suspension is pretty bad. If you ride on some rough terrain (both rear wheels on the rough part), then you might feel the rear end starting to loose lateral stability. The rear suspension is just not doing very good job keeping the wheels on the ground.
Thanks a lot for another excellent educational video. One question; is it just my imagination, or is the chain already rather dirty? Is this based upon the fact, that the VM is run with open floor hatches? I hardly ever see dirt in my DF, respectively on its chain...
What you see is residue of the chain wax I’m using. You could easily remove it by just cleaning it with a cloth, if there would be easy access to the chain 😄
Cameras overheating? I know it's summer in the north, but wouldn't have thought you'd have temperatures high enough to mess with electronics. That's a pretty active rear end, it moves every direction. Not surprised you said it felt funny.
I don’t think the problem is with the climate but instead the cameras are running hot. They are working just fine if there’s some airflow over them, but in a confined space they seem to overheat. 🤔
Hello, does anyone have any information on how the rear differential works and/or is constructed? I'm looking into how to build my own quad.. any help would be much appreciated
I often can't engage top gear either. I tried loosening the adjusting screw but it didn't help :/ Also your transmission seems quieter than mine. Maybe I'll buy a camera and make a video :) The Panhard rod is a bit of a compromise. Something like a Watts linkage would control the lateral movements more consistently but probably be heavier and more likely to break.
My 2nd gear makes more noise than other gears. I haven’t figured out why is that. But of course you cant say how loud my transmission is based on this video. I’ve turned the volume down 😄 After I made this video, I’ve realized that I can make the chain go to the last (11th) gear by switching back to 9th gear and then double tap the gear lever so that derailleur basically skips the 10th gear. Seems to be working every time. Too bad I didn’t figure this out in time to put it on this video 🤔
When it comes to the air bellows, what do you need to do to release some of the air? So, that I can then adjust the air suspension setting according to the type of riding that I'm wanting to do.
It has just regular Schrader valve. So basically you could release air by just pressing the pin in the valve. But because the air volume in the bellow is quite small, it’s probably impossible to release the air in controlled manner without proper shock pump. So yeah, use a pump ment for air suspension.
@@TheVelomobileChannel, I have a pump that I can control the specific air pressure needed. So, I have the right type of pump for doing the filling of the suspention. Just wanted to make sure that, I didn't mess anything up when re-adjusting the air pressure level for the suspention.
What sizes are your smallest two sprockets? I have the same problem with it not going into highest gear. Even with new chain and rear derailleur, although it did become a lot better. I think this problem is inherent with the lacking 2nd derailleur wheel. If you look at it from the top, the angle of the chain becomes a lot worse in highest gear.
Your dampers look fatter than mine did! Small request: Would you dare to ride on rumble strips with two wheels (both wheels on the right of course) to see how the rear axle behaves? Don't go to fast, I almost crashed my QV like that :/ But maybe, in yours it's fixed because of those dampers.

Thanks a lot, it's been very interesting! More complicated than I thought.

Thanks for the excellent videos, do you think the quattrovelo is better at handling rumble strips at speed?
Yeah, you can ride the rumble strip between the wheels, so it's no problem. Also if you hit the rumble strip, theres another rear wheel which is not on the rumble strip giving lateral stability to the velomobile.

Thanks for zhis informative video. Can you tell me the diameter of the axle? It loos so tiny)slim

Two smallest are 11 and 12.
@@TheVelomobileChannel So the sizes I have and the same problem ;)
The rear looks really complicated compared to the Roloff gear.

now thats how you RRRRRRR your RRRRRRs! this man don't need no stinkin' motor, he RRRRRRevvs like an engine!
are you selling any velomobiles right now? I'm interested
I’m not selling velomobiles.
finally. thanks for making this video
If gears don't change properly then it's not properly adjusted and needs fine-tuning.
Wow ... Far cry from a recumbent trike with a full-body fairing. ... Nice !
Put a motor in it and you could call it a Ferrari :-)
More like a Lamborghini Urus. It's still fast, but it's the SUV of velomobile world :-)
It'll never work... best off if you send it to me for disposal :)
