- Short video about a fun project.
Harald Winkler aka MEUFL, a friend of mine created a few years ago a 2 person (side by side) velomobile which was called in German language "Asphalttretboot".
This year he could finish step 2 for his velomobile and made it ready for amphibian use.
There are for sure still some little things to improve. But the first prototype works already pretty good.
Me for myself it was such a fun to have after 2 years again a camcorder in my hands.

Fantastisch, wir haben das Asphalt Tret Boot vor ein paar Tagen fahrend gesehen. Da ging es schon herrlich ab und war ein toller Anblick!
Hier in diesem tollen Film, auf dem Wasser, begeistert es mich ja fast noch mehr.
Wir freuen uns schon auf die nächsten Mobile aus Meufl's Erfinder Werkstatt! 😃
Hallo Captain Bartolo, vielen Dank für den begeisterten Kommentar. Der Film ist ja eher spontan entstanden und ich habe irgendwo auf einer meiner Festplatten noch einen weiteren Film mit dem Harald, der fast fertig ist. Im Augenblick komme ich aber leider nicht dazu den zu suchen und zu finishen :-(. Viele Grüße vom Ammersee
Lange nicht mehr angeschaut. Immer wieder geil!😊
Danke Trap Jaw für den netten Kommentar :-).
Haha this is awesome. I just thought about a boat tender that is also an amphibian velomobile. You could go from your anchored boat to the coast, drive on land, go shopping and back without messing around. Or explore the countryside of some island you sailed to :)
But I'd make it longer so it's more efficient on water and also so you could have a roof and sleep in it. Like a camping velomobile.
Thanks for the video!
Hi Dejay Rezme,
Thank you for your nice comment. Great idea with your amphibian camping vetomobile. There is for sure so much more possible if the right people invest some brain and time in such a project. Great if you are inspired through the video.
Ha! I had one of Harald's "Langlieger"s. Fantastic bike and ingenious inventer, that guy!
@TimetoLapse, Thank you for the nice comment.
A delightful display of great mechanical ingenuity! It is difficult enough to build an ordinary velomobile. But amphibious too! I wish I were smart enough to build things like that.
+kstadden Thank you for your nice comment. The best is if you try to hold things as simple as possible. So you can focus on the important stuff and have later less trouble with parts which can cause problems. If you never try to solve a challenge like building a velomobile you will not learn or getting better. Try and error is a pretty good method to get better and better with every new project.
You can tell just by the short amount of time it was in the water that it would barely last long before sinking.
Love it. Have seen a few attempts at amphibious cycles on TH-cam. The only other one I've seen that was any good was a plywood canoe with a very well engineered drivetrain - it converted from a trike to a canoe at the waterside. Have to say though that yours is the more impressive in that you can drive out of the water up a slipway! Well done :)
+Swizz Thank you for your nice feedback. I hope to show in the near future more from MEUFL and his projects.
Thank you for your nice comment.
perfect
Thank you for your comment Georgi Expert. But there is still a lot of space for improvements ;-).
@@Eddythemadmechanic i think your unit very interesting for rest. Velo drive+velo water sweemin

@Georgi Expert The velomobile is not made by myself and not my idea! I have made only the video about it. I have made and realized some other recumbents like the "Razz-Fazz" and more with the special interest of recumbent racing. But I like to combine things and do unusual stuff ;-).
fantastic work! saluts from Argentina
Thank you you tuxero88 for your nice comment.
Chile FTW.
Sweet project plus nice vid plus nice music :D
Hi Lucas,
Thank you for your comment.
The "Asphalttretboot" is made by a friend and i am sure that he would build you one if you pay him for the job.
howard stern goes paddle boating :D
Who knows, who knows ;-) !
great!
Thank you Paulus den Boer for your comment.
Thank you for your comment Paulus den Boer.
this is an awesome invention! you and your friend did a great job making it are you planing on selling it as a product cause i would love to buy this :)
Thank you youtube surfer Othello. But my friend made the invention and not i. You can try to contact him and probably I build one for you.
Nice video ! Did you produce this ?
Excellent
Hi sam sam, Thank you for your nice comment on the video.

Hi Eddythemadmechanic
I am so interested in your project
Could I have more details to discuss about it with you?
Good luck continue like this 😆
@@samsam-eb9yd Hi sam sam,
It is not my project. I have made only the video for Harald Winkler, who is the developer of this very special velomobile. You can read a little bit more about it in the description of the video.
3 years ago I started a new video about Harald aka MEUFL, but I have actual not the time to finish this video, because I am working on so many different projects that I would need a 48 hour day to finish more ;-).
Nice ride ;-)
Did your mom let you make that in her garage?? Also, don't forget to thank her for filming your sweet video.
Yes she did. Only the video is made by a friend.
🌊🚣👍Very 🏆 Nice!👍🚴♀️🌊
Hi My Perspective, Thanks a lot for your kind and colorful comment 🙂.
cette teuté quand il va dans l'eau lol. Cool concept en tous cas
Merci pour votre commentaire Peter Morgan.
Have to use stainless steel all the way it seems to me as in water the bike part will become very rusty in now time.
Hi Klimaat Konijn, Unfortunately you have not seen this very light velomobile from MEUFL in reality. On the velomobile itself are not so many parts which would start very quick to get rusty. The whole thing is mostly build with carbon fibers and only the wheels, chain and derailleur and brakes are from metal and you can protect them with a good wax from corrosion. The lake (Lake Ammersee) where this test was happen is a sweet water lake.
Ist die Kette dabei unter wasser ?
Hallo Luftschwimmer,
die Kette vom Antrieb des Propellers ist gekapselt in einem geschlossenen System verbaut.
Intriguing build. Two nits, though: first, the fussing around getting it ready for the water - I was expecting to see him cruise right into the water at speed and just keep going. Second, that drive for the prop looks overly complex, I would think you lose a lot of efficiency in all the twists and turns of the power train. Just nits, not bashing.
Hi butlerproman,
What you was expecting, to see him cruise into the water, was more than one time to see in the video. Your so called "fussing around" shows only how to get the "Asphalt-Tretboot" ready for the water because it is a normal velomobile. That this drive is in your opinion "overly complex" is not really true. This kind of machine chain can be twisted a lot without increasing the friction inside of the chain too extreme and it's only a single 90 degree turn the chain is guided. If you can tell me a much better and cheaper solution like this one, which is at least so simple, please let me know. I am so curious to see a better and efficient one made from your side. A last thing to remember for you. I am not the designer of this velomobile and i have only made a short video about a interesting project from a friend, nothing more.
Eddythemadmechanic Actually yes, I was expecting to see him cruise right on into the water, drop his prop, and keep on going. I'm guessing English isn't your first language, do you understand what it means to "pick nits"? It means to focus on a minor issue - I am acknowledging by that phrase that these are not major flaws.
I have often spent time contemplating pedal-to-prop drives and have a few ideas, but I don't have time to build any of them and try them out. It is interesting to see the setup on the lower unit as I have never actually seen one of that design. I have envisioned such a design, but always thought it would be too complex or compromise hydrodynamics or mechanical efficiency.
Neither my original post nor this one were intended to be overly critical or insulting. I read the description, so I did not assume you were the designer or builder of this amphibian, so my comments were not personal in any way. Just me thinking out loud about an intriguing build.
Yes, English is not my first language.
Sorry in case i should have misunderstood something.
The use of this twisted chains is pretty popular and the price to power output ratio is pretty good. Professor Günther Rochelt who build the "Musculair 1" and "Musculair 2" used this principle of the twisted chain there too! In his human-powered aircrafts you need every Watt you can get for take off. With a normal bicycle chain this wouldn't work so well like with those little machine chains.
I was working for him at the university of Hamburg on his "Solair II".
My friend MEUFL who build this swimming velomobile used only cheap materials and invested only his time to realize this project. It shows only the possibilities which are sleeping in this kind of HPV.
Eddythemadmechanic Interesting. I have been interested in an efficient, lightweight, and mechanically simple pedal powered prop that could be readily adapted to a canoe, kayak, or small boat. This design could be adapted without cutting holes in the hull below the waterline. I'll have to look into that design further.
I believe that you are on the right way for your project. Good luck!
Hmmm... very high windage, and no keel to counteract it. No thanks.
+effyleven No question that this amphibian velomobile is a compromise. But i am pretty curious how your design will look like and how good it performs! Please send me pictures or a link to a video with it in action on the water and on land.
Ну всё ) Теперь все бабы твои )
too complicated
The design is really simple and it is very lightweight too and this created and made with a pretty small budget and mostly from old used stuff! Surprise me with a solution which is working well and still simpler than this one!
+Eddythemadmechanic what I did mean is the change from the street to the water, would be nice, if you didn't have to change anything. But all in all it surely is a great idea 😉
Hi Johnny Pacheco, Now i got it ;-). You can drive around permanent with the buoyancy bodies but this looks not so pretty. The drive unit for the water is a different story.
