DIY Pedal Generator for Electric Bike or Trike

A pedal generator for a chainless bike or human power - electric serial hybrid. Easy to build DIY project presented by Thomas Senkel. Free Plans for aluminum parts included at 0:43 in this video.
A Keyde front hub motor is used as a generator. It is nominal rated with 160 rpm @ 36 V and 250 W.
Keyde 98SWXN36 with 160 rpm

You dont need any electronics, just a 3 phase bridge rectifier. The lithium ion battery is 12s (44 V) and 2x 25 Ah. The motor power is up to 5 kW.

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.

Die Ausführung ist einfach so perfekt, die ganzen schönen Drehteile, geschweißter Alurahmen, eigens gebauter Motor. Unglaublich!

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.

can you make a video showing the building process of the bike? And go into detail on the motor and stuff like that?

[jsimo]

as soon as i saw you were machining parts i knew it wasn't a simple DIY

[officebroomer]

What a great design, impressed by the quality of the built !

[lights]

Absolutely a genius idea, so well executed with wonderful precision. My hat is off to you.

[eltunene]

Excellent! I am a sun power fan, so I would add a 250W panel acting both as a roof and as some extra power.

[TheAmericanUhate]

Really awesome design and idea! I hope you keep this project going!

[jm]

Simply great. Electronic transmission - no chains or like. Perfect.

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.

[HoverbotTV]

Very clean! A dustbin body faring and you will almost have a self propelled endless ride. Maybe a high tech tuk tuk!

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?

[arrowstheorem]

Thats beautiful craftsmanship and technique. You must be a German. Ser hoot!

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

[vaporainwaves]

Wow, you are good damn engineer. Amazing work.

[vijaymohan]

please upload blue print too and can I use this plan in bicycle?

[adams]

Great design! Thanks for sharing, I will definitively try it on my trike.

[patrickmckowen]

Nice ETrike - Thanks for sharing.
Cheers, Patrick
