I'm building a tryke myself, mine has tilting capability and a cabin for added aero, safety and weather protection. I post on my channel whenever i make some progress on the project for those who want to check it. Your project is very cool and has some nifty ideas.
This is great, Thomas. I've been thinking about a system like this off and on for 15+ years. I'm happy to see you've taken the initiative and applied your talents to bring something like this to reality.
Pls can you explain it further to me
@@nnejiamaechi9385😢wonderful.video..please make us understand this...
What a great design, impressed by the quality of the built !
Die Ausführung ist einfach so perfekt, die ganzen schönen Drehteile, geschweißter Alurahmen, eigens gebauter Motor. Unglaublich!
Really awesome design and idea! I hope you keep this project going!
Wow, beautiful build!
Excellent! I am a sun power fan, so I would add a 250W panel acting both as a roof and as some extra power.
Nice ETrike - Thanks for sharing.
Cheers, Patrick
Absolutely a genius idea, so well executed with wonderful precision. My hat is off to you.
This is so inefficient as far as distance you will travel vs. time and effort put into pedaling that I can't imagine any benefit that could redeem it.
A chain and sprocket drive is 98% efficient. This trike has a sprocket & chain to the generator, so already you are at 98%, the generator is only 80-90% of that 98%, the battery accepts a charge at 65-80% of that, outputs only 65-80% and the electric motor is only 80 to 90% efficient. You end up with about 30 something percent efficiency at best in a heavy, expensive, complex vehicle compared to a regular trike that has a 98% efficient drivetrain. At best you would travel only 10 miles for the same effort that could get you 30 miles!
This might be a hard sell merely due to complexity and price even if it's drivetrain was 100% efficient. Somebody tell me what percent efficiency would it need to have for you to pay a lot more for a trike you could charge by pedaling as well as plugging it in and/or using a solar cell?
@@denbecr49 internal combusion engins are 20-35% effcient and that is what most of the world uses to get around. average person could care less and not having the super long chain from pedal to wheels makes for a much easier to build trike
@@solarroofing8072
If that's all that counts, start with a unicycle, add a frame with 2 rear wheels and enjoy lightweight single speed high efficiency with no chain.
Nice job on the suspension system and a really good no fuss video. Thanks
Wow, you are good damn engineer. Amazing work.
Simply great. Electronic transmission - no chains or like. Perfect.
I wonder what kind of efficiency could be achieved this way. I'm sure lots of people would love to never have to tune a derailleur again.
Great design! Thanks for sharing, I will definitively try it on my trike.
very nice, thank you for sharing your achievement and success, great job
brilliant machine - i want one! good luck with your project.
This is so cool! Love the engineering.
can you make a video showing the building process of the bike? And go into detail on the motor and stuff like that?
Goods
Super nice! Thanks for that video!
as soon as i saw you were machining parts i knew it wasn't a simple DIY
Such a great design and output... 💯💯
that is genius!!!!!!!!!!!!!!! nicely done c= two thumbs way up!
absolutely love it!
Marvellous. My thanks to you from Turkestan Kazakhstan.
thats pretty slick man nice job
Nice work, great ideas, I would like to build one similar to this.
This is awesome! Congrats!
GENIO, SALUDOS DESDE ARGENTINA
Superb design all the way around. I'd give this ten likes if I could -- it must be the best bike video I've seen all month, at least. 5kw motor power is insane! That'd power a smaller car around town. I think I need more sleep before the finer nuances of this design come through but you and your tricycle hit across why I came very close to parting with $3,000+ and did not -- lack of a good suspension.
And I don't regret it because every trike rider I see I ask one question "If you could change one thing about the bike what would it be?"
and so far ALL of them have said "I'd add suspension" or "shocks" or "a smoother ride" and I live in the most populated area with the largest density of bike paths in probably the whole midwest USA so I get to ask a lot of people on a lot of different bikes. Plus I never see one in the snow. Why is that?
Very clean! A dustbin body faring and you will almost have a self propelled endless ride. Maybe a high tech tuk tuk!
Супер техника! В скором будущем сделаю себе такой))
Love this project...
Thanks sir...
This is where your workshop located. Good testing spot.
wow, I realy like this idea
Beautiful machine work. Very nice.
Thats beautiful craftsmanship and technique. You must be a German. Ser hoot!
hello
i like you good invention , it can save fuel and polution levels also ... great
Great build mage. You change the pedal section a bit and ad a fly wheel to continue making charge after you stopped peddeling.
Aslo could you add an ultra capacitor to take some of that large voltage and then carry in charging the batteries.
Maybe both together could really reduce peddling time.
Amazing build though and I'm very inspired by it.
Would love to hear your views on my ideas xxx
Thomas Senkel! Very well done. He is a prime example of superior German engineering and technology. However something like that I'm sure could be used to power a boat.
+unhooked25 --- You DONK!
HUhh! The Keyde motor is a known lemon which has made a lot of people rather upset at the sale's hype... It simply does not hold up and many times is delivered failing right out of the box...
And you stand a great chance to have to threaten the bastards via Paypal to get them to service you properly!
HUhh! I'd hate for this thing to flip me forward like a whip flat faced on the pavement under a heavy breaking scenario! or kiss the hard bumper of a tank passing by, huhh I mean a Smart Car!
GERMAN ENGINEERING AND TECHNOLOGY LMAO!
All I see is a copy-cat of all the systems already present in countless machines plastered all over the net. [ like the Carver, T-Rex, and dozens of others, etc...] huhhhhhh! buddy! what is so grandiose!?
Perhaps good as a kids toy, a go-cart of sorts... hmmm roll-cage please!
Best people BEWARE of your HYPE and do some due diligence and find out the better equipment... and don't dream you will be traveling in a go-cart surrounded by Smart Car size tanks!
...and you are sure it could power a boat! LMAO! yeah... the Hindenburg!
You sound like the fake witness(crisis actor) in the street in New York who stated: "...and I am sure the towers collapsed due to the heat of the fire!!!..." LOL yeah! symmetrically, and at gravity speed!
LMAO!
Probably you are right and the Keyde is a very poor bicycle motor, but it works very well as a generator. And is very light weight.
Great project!
Grande progetto...... complimenti.
Nicely done!
Ive considered this over the years, but for 2 reasons havemnt adopted it.
1) Its not legal to have an ebike on the road without direct mechanical drive to the wheel, in Ontario.
2) Adding energy to the system using a bicycle chain, is more efficient than a generator and rectifier.
Still i respect like your work and like your videos.
Beautiful!
Very nice work
Amazing... but... if you use super capacitors your recharge to the capacitor would be more efficient than charging a battery.
what a home exercise machine.. I love it.
best video I've seen.
THIS IS GREAT! PLEASE SHOW MORE 😃.
Very nice , but try to go to higher voltages and lower current ! Then your batteries will be drained less and will stay fit longer.
Do you also use the BackEmf of your motor to recharge the batteries ? Have a look at SegelOhrenBob latest Bedini Scooter Video.
Regards , Stefan.
Michael Johnson sir I have no idea and I am curious as to if they actually run out of power at different times, or they just are the same?
Kind of like a pound of feathers and a pound of stones no? It's all relative...
Michael Johnson the 24v system will be more efficient, since it will waste less power in the transfer of current.
@@michaeljohnson_ok You want to run your system at highest safe voltage. It saves energy which would be wasted as heat in wires, it also saves mass as you need much thinner wires
Excellent work..
Beautiful engineering! It looks like it has a very smooth ride - and is very quick too! Do you have any feedback for net energy usage on the battery, or have any indicator of energy remaining in the battery? How does it react when the battery gets low? I like how you can generate power when stationary, in case it runs out of power, then you can recharge somewhere in the shade or a place with a beautiful view. Nice job!
Nice job, fine craftmenship..I believe that a hover board motor has enough pole (16-20) that it would be possible set it up as direct-drive (no chain) pedales right to generator. I don't want to see you labor to much.. but sure love to see that on one of your projects. Good Luck!
Show perfeito muito bom seu projeto
Great work.
i need more details regarding hub motor ,generator, and battery configuration plz
Very good. Beautifull neighborhood also.
Such a great idea I love it! What if you added a flywheel on a freewheel to your cranks? You could get it cranking and then stop pedaling while it keeps spinning acting like a mechanical capacitor. Great video
Very impressive!
*Works great, nice height.*
Hi, congratulations, nice work!One question: is this a motor with internal gear or is it a direct drive?i heard that hubs with internal gears won’t work as a generator...thanks for some insight!
This is great! I've been thinking about a similar project. What speeds would you achieve by powering the motor directly from the generator without a battery?
So 160rpm at 36v has nothing to do with like a 160kv motor rated max 29v right 😧 those are totally different specs ?
Di mana bisa beli generator tersebut? How mach?
I like the idea of a gas engine spinning that to run my electric bike, distance would no longer be an issue:)
could you provide better photos of the bike itself? im more interested in that than the special motor adapter
I would like to see plans for your bike - especially the front suspension. Looked very interesting.
One of the best idea for battery plus pedal-powered Hybrid. For long ride, more lazy rider get, dead battery even sooner.
No. This is extremely inefficient. You would have to pedal it for many hours to charge a battery. Much smarter to plug it in or use a solar panel.
or maybe use in combination with solar the organic transit elf has one but not this generator
Adding this to the ELF would be dead weight and so silly, the sun effortlessly provides what you'd have to pedal very hard for. Pedal power is smarter when used to get you directly from A to B. I never need to plug in my ELF, it gathers all my transportation energy needs in just half a day for my local trips. In three years I have never exhausted my battery even once.
Popeye Gordon please look up raht racer same concept and you sound like a Donald Trump supporter
with all the skepticism
Nice idea, would be cool to see it run the motor wo a battery connected.
Love it!
ultra capacitor would be cool to try. very cool
I love this project. Please tell me if I can make a bicycle or e bike with this concept. it would be a great favor. waiting your answer.
Can this be done with recumbent elliptical exercisers that do not have pedals? I have limited mobility and cannot rotate my knees to pedal. I want to create energy with the elliptical exercisers I see. Do you know if this is possible?
From the meter it looks like you are making enough power to make the bike go, would it be possible to use a capacitor instead of a heavy battery? Or bigger dynamo/gearing?
how did you build your own motor it looks great!
I am building my own trike and want to add electrical drive motor too.
very very good invention thanks mr bhargav
Wonderful. Please let us know have you used Charge controller for battery charging or direct connection from rectifier.
hello, congratulations to the idea, and thanks for sharing ... where can I download the complete trike design?
A very nice project, congrats.
question: do you sell the motor plans? I have a recumbent trike and your idea inspire me to build one similar to yours.
thanks for your information and keep going.
I also have a two wheel recumbent bike and it is a very good idea to solve the problem of the chain which interferes with the front wheel
What was it that you bought in that box there that was the perfect shape for your project?
Interested in building process too. Also, where are you from? Seems like really beautiful place. I'm really amazed by the surroundings.
The number of likes is testament that your project here has much interest. I say, take advantage and create kits. Kits allow others to innovate and to get involved. Also create a Patron channel and make pathways to continue your great work.
I will think about that. But first, I will build a direct drive generator.
@@forschungsbuero I will the first one to support your work by joining your Patron channel.
@@forschungsbuero As in ironless axial flux generator possibly using the Litz wire? Now that has my attention. I'm thinking about construction of my own series hybrid recumbent tricycle. The motor will be maybe this one www.leafbike.com/products/e-bike-hub-motor/48v-52v-1500w-front-spoke-hub-motor-electric-bike-motor-1063.html (efficiency up to 90.5% which is impressive). But the generator with about 200W output... thats hard to come by. And directly driven one, without gearing... unheard off. It would be able to generate up to 200W with only about 90-100RPM.
Is there a charge controller? I think efficiency is a big problem. How much benefit in terms of energy are you returning to the system to make this feasible?
I love your video:D
Due to losses in charging it's best to cycle then generate when going down hill.
Regenerative braking is not possible on this trike, because the motor is coupled to a freewhweel hub. Could work, if you block the freewheel.
I love it. It is just what i need for my E-Trike. How much does it cost?
Splendid.
buen dia Thomas, un proyecto muy interesante e ingenioso, tendras mas datos del generador que usaste, KEYDE 36volts, sin escobillas (brushlees)???, sin engranes (gearlees)??? que tantos wats entrega???, agradezco de antemano su atencion, saludos
with something similar,can you make a bike that is mostly manual but get a big or small boost if needed? would a crank type generator hooked to a motor work?
You don't really need separate generator/motor units and no way will the rider be able to provide the force needed to keep the batteries charged. Most hub motors can be switched to generator (regen) mode through it's controller. You may then be able to take advantage of kinetic/pedal power to replenish the battery.
nossa fico muito bom
please upload blue print too and can I use this plan in bicycle?
Very nice series hybrid EV.. kudos
Hey, very nice product ! Amazing building quality !
Did you use standard bicycle pedals to mount on the setup ?
Is the sprocket mounted to the pedals standard or is it custom made from scratch ?
Thank you very much !
+PL Savoie He used a T.A. Cyclotouriste crank.
Hello Thomas
Could you put the reference of the motor/generator that you use to charge the batteries? Where did you buy it?
Thank you
It is a Keyde front hub motor, 36V. I bought it on Ebay a couple of years ago, but I dont see the seller anymore. Try on Aliexpress. You can use other hub motors, too. But they are probably heavier (than 1,4 kg).
Haben sie mal gemessen, wie effizient so ein Pedalgenerator ist?
Yes, this is easy to build. All you have to do is make your own motor.
Or use any motor off the shelf. With "easy to build" I refer only to the pedal generator, not the trike!
I ENJOYED UR CONCEPT WITH BATTRIES U CAN ALLWAYS BE CHARGED,,, I LIKE TOO KNOW WHERE U GOR UR RECTIFER FROM,,,
Hello. Thanks for posting. What is the efficiency of the pedaling => electric energy system?
super schöne Arbeit. Kannst du kurz (auch auf englich) die Vorteile gegenüber eines direkten Kettenantriebes auf die Räder erklären ?
This is a CONCEPT !
good work , y put it on the crank, come of the wheel .
Красавчег! вот бы мне такую звезду переднюю!!!
Hi, its really cool this project, please can you send again the free plans for aluminum parts?
