I got the disc brake on the front Sunday. I test rode it again and it's pretty fast. It's quieter than I expected with the 530 chain. Not loud at all. Got the belt aligned properly. I had an issue with the rear sprocket. I think I forgot to torque down all the bolts because it developed a wobble...

I finished the battery box earlier. Almost. It still needs to be sealed up and I have to modify the cover a little bit so it fits right but it's on the bike now. I made a track so that it sort of slides in from the side and then I latch it in with the two toggle latches. The wire exit isn't...

Got the rest of the battery done this week. The two packs are separated by two layers of heat resistant foam padding with a sheet of fiberglass sandwiched between them. The ends of the packs which will be in contact with the steel housing are covered by 5mm thick silicone sheeting. I have some...

I got half the battery built. My MOT spot welder was not powerful enough for the copper nickel sandwich and I ended up blowing the mosfets during my experimentation. This was my fault because I accidentally let a wire touch something it shouldn't have. Since I wanted to get the battery done this...

Thanks for the tip. I'll definitely keep an eye on it. Maybe I should ride it around with no motor once I get a more suitable crank and the freewheel on. I did stand and jump on the pedals after I welded it. And rode it around in the driveway scooter style on one pedal. Although It seems very...

Got to work on the bike this weekend. I finally found a suitable donor bike for the bottom bracket shell and associated tubing. Turns out I was looking in all the wrong places. Behold! The purple princess bike! It was the perfect shape and put the pedals right about where I want them. It's...

I got some more work done on the bike this weekend. It's been pretty cold lately but we finally got a little break in the weather. I got the motor mounting, belt, chain, and rear sprocket sorted. Also made a headlight mount. I used a timing belt tensioner pulley from my old 87' Plymouth...

Added the seat mount. I was able to sit on the bike for the first time! I'm going to begin construction of a smaller test battery pack soon. I want to build a smaller one to get some experience with it before I go all out. I am unable to fully test my controller because I don't have a big...

Made some progress this weekend. I have the jackshaft and the motor mounted to the frame now. I still need to reinforce it a little but it's most of the way done. The bracket for the motor bolts on and allows some degree of adjustability. I'll be adding a few more attachment points when I decide...

I got the brain board up and running this week. I was sick last weekend and didn't go work on the bike I just stayed home and worked on the controller project. I have the output section mostly together. My original plan didn't work out exactly how I imagined it would because the pins on the...

My boards came in today. Apparently DHL delivers on Sunday that was a nice surprise. The brain board is complete. Waiting for my pickit 3 to show up so I can program the chip now. I'm waiting on the copper sheet for my bus bar and some various resistors before I begin constructing the MOSFET...

Haha. I've seen some pretty slick water cooling setups on PCs actually. It can look pretty cool if it's not too overdone. I was mostly joking but it might be useful to have a way to see inside the reservoir. This thing is already going to look pretty crazy as is and I'm not trying to attract any...

I definitely will! I'll be working out the details of the system soon. The location/size of the reservoir kind of depends on how I end up mounting the controller and the battery. After I have the motor and the crank/pedals on the frame I'll start to focus on those things. I just ordered the...

A torch probably would have worked. I don't have one though and I needed a big soldering iron. I looked at some smaller butane torches when I went to get the iron today. My main concern was the possibility of getting soot in the joint. If I had used one of the barrel type splices I'm sure a...

Ok, so, I got a big soldering iron from the hardware store. I got the connections soldered up and I'm happy with the way they turned out. I sure did use a lot of solder on these! I'm going to have to buy some more. I used the intertwining method then I used vice grips to clamp the strands...
