Hello all. A couple months ago I came across a RadWagon for sale on my local Facebook Marketplace. I have been buying and fixing up regular bikes during the Covid Pandemic as a hobby, so I was interested. I also have an Ejoe Koda e-bike that I really enjoy. Anyway, I went and checked out the bike. They were asking 200$. They said they bought it as a project and the previous owner said it needed a new battery. They never did anything with it. I decided to take a chance, since I figured there were more than 200$ worth of parts if I ended up not making it work. It has a suspension seat post which I see retails for like 80$, so there's that right there.
I got it home and started cleaning it up, it was really dirty and scuffed. I found that Magic Eraser sponges really cleaned up the scuffs.
It was during the cleanup that I discovered the bent fork. I should have noticed it before, but it looks like it has been crashed and bent back a little. I know that bike shops have fork and frame truing jigs, so I'll look into that before looking at buying a new fork. I spun the wheel before purchasing and it was true, so those heavy duty spokes must really work.
So, I also tried to charge the battery when i got home. The bike didn't come with a charger, but I already had one for my other ebike. The battery didn't seem to take a charge. I thought I would do a little investigating, though, the battery box is really broken and seems to have been modified so that the battery is directly wired to the pigtail that normally comes off of the battery holder. It was pretty easy to take apart since most of the screws were broken off. When I took it apart I found that a 5amp fuse was blown that was inline with the charging port. I put a 3a fuse in that I had laying around and boom it started charging. Cool!
After charging, it shows a full battery on the display, I also have a little meter that I hooked up and it showed it having 54ish volts. The battery may still be good. That would be sweet.
The stock radpower controller and display gave me an error 30 message. I tried cleaning contacts, etc. but it wouldn't do anything. So I figured I should try a new controller. To buy a new controller from Rad is kind of expensive, and a company makes an upgraded controller that works with the display, but my display is kind of junky, so I figured I'd do a new controller + display, so I order a GD01 display along with a 30A controller that has the same motor harness as the one on the Radwagon.
In the meantime, I replaced the fork, cables/housing, grips, and tires.
I got the new display and controller the other day. I hooked them up so that the controller is connected to the battery, the motor, the display, and the throttle. I discovered that the brake plugs are different than those on the 1 to 5 wiring harness I got. The display will turn on, but when I turn the throttle, the motor doesn't move, but I hear a very slight click coming from the hub motor. There is also an "ERR" on the display. Any ideas?
