But that is F A R from the story! I started with absolute garbage, built with nothing but garbage, and did it as fast as I possibly could (on video).
$200 completely roached "ebike" from a machinist on Craigslist
* Completely dead battery, reverse engineered it and threw it away
* Box of "parts" - half of them there - half of them were not
* No chain or rear derailleur, front clicker no rear clicker, various cut cables
* No seat, controller and throttle not working
* Front hydraulic brake rattling loose, rear missing bracket and full of air
* Two flat tires, random fasteners loose or missing
* You get the idea. . .
To that I added the following:
* 4pcs Ryobi adapter
* El'Cheapo Amazon 36V/48V controller that will run sensorless
* Old throttle
* WAGO 221 clips in large and small
* $3 in baby oil
I got it rolling with a front brake, 2pcs Ryobi in a backpack, no chain.... Typical Right?
Once I could see it was actually viable, I got the front and rear brakes functioning with a "Ghetto Bleed" - this is baby oil on the side of the road! Got some Ryobi in there...
I punched it all out SUPER ROUGH - nothing but a drill and a battery saw. I always build rough to figure out where I have gone wrong as soon as possible. In the example below, you can see I put the packs TOO CLOSE TOGETHER!
CANT REACH THE RELASE BUTTONS.
Yep - Dont Know, Dont Care.
At this point all I want to know is if it works, in any way
Then I got the chain on and the brakes bled out
BRAKES - IMPROPER BRAKE JOB, EMERGENCY ONLY, WORKS!
Anyhow, you get the idea
Those are 465W "Broken Solar Panels" that belt out power all day long. No ingress issues.
These days I am far more interested in battery powered propulsion that can survive salt spray. . . but I built this one just because I always wanted to. Original Credit goes to ... eh... er... Doc and ... er... another guy -> They built tool-pack bikes like a decade ago.
