df velomobile: testing and a Strava segment
Вставка
- Опубліковано 13 жов 2024
- Finally got my df velomobile configured for 12-speed and a 65/36 chainring setup so I can do some climbing. And I have a new extension for the GoPro mount to test on descents. Met up with my friend John Abbey during my 147 km ride and he also tackled a Strava segment successfully.
13:30 I would never pass a child at that speed. You never know what they'll suddenly decide to do.
Excelente recorrido ❤
Incredible that the design allows such speed with human power only. I rode a Quest 7 years ago and it was wonderful but no where near as fast as this.
I have a new one coming soon that promises to be significantly faster.
@@shenzhenpingpong didnt age well LOL
🇨🇵Impressionnant de vitesse merci pour ce moment🇨🇵
Lol his music blasting at the end 😆
Crazy speed
British racing green might be a slow colour for a Jaguar but it looks like a really slow colour for a velomobile. Velos need to be light colours for them to go the fastest.
I think you got the KOM 😂🧨🏆
Amazing speed. I drive an „old“ Quest. What changes did you friend make for this speed? Is it a Carbon Quest?
Thx an greets from germany.
My friend unfortunately was killed by a drunk driver earlier this year. His fiberglass Quest XL is heavily modified. Well, I should say, it was. It was shattered into a thousand pieces when hit from behind. Anyway, he told me he made it much stiffer by adding reinforcement inside. And he had the swingarm replaced with a stronger one. I really miss riding with him.
@@shenzhenpingpong I am so sorry for you anf you family. Which you the best and much hope! Please stay save. :-/ :-(
@@shenzhenpingpong 😟😟
is it difficult to shift from 65 to 36 and vice versa ? the chain could jump easily on big size difference of the chainring no ? BTW, great speedy ride, and you are handing your df very very well, stay safe !!
Yes, there are a couple of tricks that I needed to do to make the 65T/36T shift work properly. I use a 65T chainring with a built-in guard from Alligt so it cannot overshift. I also file down two teeth on the 65T chainring so it can more easily release the chain to drop down to the 36T.
Wow, that was real fast, and I like your helmet. It scared me a bit to see you passing the car in the shoulder, did they know you, or did they know you were coming?
I think it's possible the driver knew. The Casco helmet shield is good wind protection at high speeds.
That looks like a blast!
What trail did you go on for the second half of the video? Man I wish I had access to such a trail where I am..... looks super fun especially compared to city traffic like I have. Have you ever gotten a speeding ticket?
No, I don't want points on my driver's license. This is called The Loop, Tucson AZ. It is superbly maintained. webcms.pima.gov/cms/One.aspx?portalId=169&pageId=720204
@@shenzhenpingpong Would they give you points on your license? It is still classified as a bicycle isn't it? I guess the question is, is it even possible to get a speeding ticket on a bicycle.
@@100toeface , yes, they can give you points on your driver's license even when riding a bicycle if you make an infraction. The local police confirmed that to me.
Out of curiosity, what model and size of tires are you running on?
Schwalbe Pro Ones 28-406 on the fronts and Continental GP 5000 TL 28-584 on the rear.
It's fantastic to see this great vehicle and its speed but 13:33 to pass small children at 53 km/h is crazy.
Yes, high speed has to use good judgment. Sometimes I will stop, sometimes I will decided to pass at speed. It's my commute route. So it's something I know and ride all the time.
You ever try the hood with it? Is it too hot?
Most of the year, it's too hot, But in winter, I will use the hood.
so when you are doing 60kph on the flat... how many watts are you burning?
I see you are wearing a Casco RS helmet with visor; do yo like it? Can you rest your head with this helmet on its rear-side? With some helmets this just does not work well for me, and the Casco is quite an investment.
I am considering buying a Insta360 OneX2 cam. Already have a mount with three suction cups (needs testing). I am thinking of putting the cam and mount in an aerodynamic shell made of a cheap soccer ball cut in two (one part serves as the shell). The cam should just stick out. Will tape the ball to the DF body. This set up may give a better streamline and also serve as a safety catch when suction cups let loose.
Sorry I didn't see your comment until now. It's a good helmet because of the rounded back. But I don't like to rest it against the back, so I use a neck rest roll from Ventisit so I have a small gap. If you made that soccer ball modification, let me know.
@@shenzhenpingpong That is ok. I bought a second hand Insta 360one and still figuring out how to mount it behind me on the DF, probably in same position as where you have the Gopro. But I don't like drilling a hole... How do your mirrors work in that position? I am happy with my Casco Speedairo 2 only my ears are kind of sticking out and there is a lot of wind noise as a result.
I like your extensions where your shoulders are, only they might add safety if they were solid and would hold a body inside the shell during a roll-over (like in a Milan). In addition a 'halo' construction would add additional safety. This entire extra paneling should ideally flip forward as in a Milan. I have an idea for the construction of the carbon reinforced ribbing necessary for the halo.
Now: time. What is your opinion? I think your aerodynamic additions are really good, only they need to become part of additional safety features as described above,
@@ArjenMeurs , a proper rollover bar and a halo is probably a good idea. Sounds like a cage of some sort. To execute the idea would require some expertise in carbon-fiber. Unfortunately, that's not currently in my domain of expertise yet.
hello from germany I have DF XL since one month...can you give me some tips how fast I can go in corners....
It depends on how you sit (you want the center of gravity close to the front wheels). And you need to sit as low as possible. Also, the tires matter a lot for cornering grip. Then you can experiment with lower speed turns and see at what point you go up on 2 wheels or understeer (front wheels losing grip). Hope this helps.
Dang bro..that rt on st marys..yeesh..be careful...
Yeah, St. Mary's is not so safe. Same goes for Speedway, Broadway, Grant etc.
good old DF, guy tuned his to be 97 watts for 50km/h beating the newest w9s alpha series.
can you send me a link to that amazing result?
@@shenzhenpingpong youtube deletes it as spam. i think he closed the front hole and put pro one tt in front with newest corsa pro speed. that air intake causes to much drag same as the maintance holes in rear up to 16 watts cuz of small gap. just place nitto tape around it
I’m in Arizona I’d love to see your velomobile if that’s ok?
Hello are you in Az ?
Awesome
👍🏻👍🏻👍🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻👏🏻🇧🇷
If I owned one of those things I would make sure it would light up like a christmas tree with leds going all directions and different blinking and colors.
In daytime, the back has a Varia Radar taillight with pulsing red LED. Pulsing rate quickens when the car gets closer. Also, cars are individually tracked on the Garmin display unit. Plus there is a real-time rear view camera at the back. And a monitor inside the cockpit. Plus there is a mirror. For turns, there are LEDs turn signals front and back. And of course, there is a headlight up front. And there are constant-on red LEDs for night use. Then there are extra LEDs (non-standard) on the rear that can be switched on independently of the headlight.
@@shenzhenpingpong have you ever considered having a flagpole sticking up behing with a light on top?
@@z0uLess , of course. But it's aerodynamically horrible. I know because I use a vertical selfie stick with a GoPro on top to film sometimes.
Mine is..lol
Damn sandy..so fast..damn
what a 98km/h 😂 Be careful
Eletric engine?
Yes, entirely powered by my legs. I'm not a strong rider, so if you have high power output, you can go much faster.
@@shenzhenpingpong Probably not that much faster, though. You benefit a bit from the less dense air in the dry climate of Arizona.
@@rhein228 , yes you're right. We are at around 850m elevation, so that helps with the density. But there is also less air to breathe when working hard.
@@shenzhenpingpong at 850 m the lack of O won’t be felt as you’re used to it. Come to my area at 50 m with high humidity and you will clearly sense the „thickness“ of the air
@@rhein228 , but don't forget dry air is denser than humid air.
I’m in Arizona I’d love to see your velomobile if that’s ok?
Sure. Where in AZ are you?
I’m in Phoenix

Are you on messenger FB?
