Gute Motoren baut man nach dem Newman Prinzip mit hoher Spannung und kleinen Strömen. So halten die Batterien wesentlich länger ! Man schaltet alle Batterien in Serie und lässt nur einen kleinen Strom fliessen und haut die BackEMF immer wieder voll auf die Batterien zurück, wenn der Kommutator umschaltet. Damit kann man 50 bis 90 % der eingesetzten Batterie-Energie wieder zurückgewinnen und die Batterien entladen sich so sehr viel langsamer, so dass die Reichweite der Elektro-Fahrzeuge erhöht wird...Höhe Strome bei kleinen Spannungen zerstören nur die Batterien sehr schnell...das bringt nichts....
Oh, how I wished I had you onboard on my project. It is going to be a cargo bike + a stroller and I hope to be able to put in an electrical motor as well for the really bad knee days or steep hills. I intend to walk/bike from Sweden to Gibraltar.
Giant made a bike like this they tooknof the market ,i condider it a mistake,its a very confortable bike and many people need this type of bike for many reason.
Oh, I like pedaling. The motor just helps going uphill. But the chainring has to be bigger, to give more speed. Thanks for your comment; image stabilizer is off, now.
forschungsbuero Try a design without the pedals. And if you must have pedals for legal reasons, have symbolic pedals on a generator instead of chain. That you like to pedal is irrelevant. It's about engineering elegance. UFOs have no pedals. Clean, simple, perfect.
A lovely looking bike. The cross section of the frame is very similar to that of my BikeE. It proves how intelligent the original design was.
Ace design and great build mate. Well done. Looks fantastic to ride, thank you for sharing
Great engineering, great project. Looks confortable. Good luck for production!
3:08 was that a speed sign or the gradient? ;-). Great built, love that you already were using LiFePO4.
Very nice! I'm having trouble finding small front wheels like that for my own next recumbent bike project. Where did you get yours?

Your bike looks well thought out. Where are you located?
ELECTRIC bikeE still working for you? I am going to do a conversion on my BikeE ..
I have a similar recumbent, the Bike E. I'm interested in how you made the battery holder. what material and thickness? Thank you.
I like the frame idea
don't your knees get tangled in the handlebar though? They seem to come up quite high.
cool bike, looks pretty much effortless going up that hill....
One day, i will own one of this and cruise along ;)
My friend, when is gonna see the volocopter flying with pilots inside? thanks
beautiful place !
Great concept.
I guess this never got to production?
Great job sounds like you were gasping for air.
Bike-E based E-bike

Świetne rozwiązanie. Great idea...
I don't know if I'd trust a clamp on suspension system long-term!
Where did you record this?
La Palma, Canary Islands.
forschungsbuero Very beautiful! Remembers me of Madeira.
What is the top speed on that?
Why is the Front wheel smaller?
This gives lower pedals and an upright seat position.
That motor needs the amps bumped up bad. :)
how do I get one of these bikes?
WoWmazing !
poño
Very nice. But get rid of the pedals. They are complex and uncivilized. Simplify the design. And don't use youtube image stabilizer.

forschungsbuero Dan Frederiksen You need at least a 3000 watt motor for a 80kg bike to climb that slope without pedaling.
Phil'sTechHelp no you don't. it needs a certain torque. and the smaller the wheel the less torque needed.
Hey Dan, now I have built a pedal generator as you suggested. Check out this: DIY Pedal Generator for Electric Bike or Trike
You need a helmet.
do you have plans on your design, i would love to copy your design for my own
