I ran across this recently and found it intriguing. It is a DIY Pedal Generator for Electric Bike or Trike. What a neat concept … pedaling to produce your own electricity to operate the motor to propel your trike.
Here is the YouTube description: 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.
I will be the first to admit I don’t fully understand it all, but it looks really neat.
A Keyde front hub motor is used as a generator. It is nominal rated with 160 rpm @ 36 V and 250 W. 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. Top speed more than 80 km/h (50 mph),
Range 60 km (37 miles).
One would obviously have to know what they are doing and have the necessary machinery and equipment to tackle this DIY project. Ya gotta admit this looks impressive.
This also allows you to go pretty fast compared to a regular conventional human powered trike.
Another great aspect of this is that it allows you to eliminate the long chain run typical on a tadpole trike.
Here are a couple of videos of his e-bike showing what this design and build is capable of.
Like I said … pretty impressive! Regardless of whether or not you are a strictly human powered triker or motorized …
ENJOY THE RIDE!
A FREE GIFT awaits you!
