DIY Pedal Generator for Electric Bike or Trike 

Pls can you explain it further to me

​@@nnejiamaechi9385😢wonderful.video..please make us understand this...

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.

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.

+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.

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.

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

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

Or use any motor off the shelf. With "easy to build" I refer only to the pedal generator, not the trike!

Very nice series hybrid EV.. kudos

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

The power cannot be increased with more generators, because it is limited by the human capabilities. Belt drive is nice. But the noise comes mainly from the internal gears of the generator. I will try to make a direct drive generator some day.

I am working on a direct drive generator with power modulation. As soon as I have results, I will make a new video.

@@forschungsbuero thanks bro💕
