@sirlongass, Shit, you're right, funny pic dude. I was going to rock it that way lol. I was going to use it for superman seat grabs (pic below). Flipped that sucker around and what do you know, fits slightly less shittier. Going to add some additional brackets and mounts to get the seat some more support as I moved it down and back.
So I had quite the interesting weekend with this thing. Friday night I came home from work and put the kid down so I could work late on the bike. I was able to get the seat adapters mounted on the frame. These are brackets that have the same bolt pattern as both the frame holes for the seat, and the holes in the seat frame (they're not the same distance apart). This involved some drilling, but that was no problem. I got the battery box all cleaned out and then started lining it with foam that came with the battery. I also used some RTV to hold the various pieces of foam together, just makes things easier. The battery has lots of padding and fits so nice in the battery bay. I made the custom cables needed to get the battery connected to the sabvoton. Got everything hooked back up, cool ready for a test ride.
The test ride. I noticed that the front suspension is such shit, I need to do something about it, but don't want to spend the money (bigger fish to fry, read on). The rebound is really aggressive and the bike is so heavy which doesn't help things. Anyway, I cruzed it to the skate park and check things out for a bit and decided to take off. The motor temp was warm but not too bad, I was pulling 3-5kw constant going to the skate park. There's a big hill leading out of the skate park,wanting to see what this thing can do I grab a hand full and headed up the hill. The bike was climbing (not awesome torque) and about half way up, I head a creak and lost all motor power. The TFT screen was showing error 07h and the sabvoton was blinking 13 times. I googled the blinks on the side of the trail and realized it was a hall issue, weird but ok let me swap them since it has two set. I do the swap and nothing, I'm getting the same error. Motor was scorching hot, so I thought maybe it was being thermally limited. I try and try, no go. So I did the unimaginable, I started pedaling, damn it was so hard, and it felt like there was motor resistance. So I did the walk of shame to the nearest grocery store and called the wife, and got a ride home. (Side note, the motor was hotter at the store than the side of the trail. wtf)
I was so bothered by this first real test ride when I got home. I parked the bike and started doing other things. Then I got so pissed that I took the damn thing apart again and opened up the wheel, stunk like shit! I definitely fried that damn thing (pics below). The temp got so hot in the motor that the yellow wire of the hall sensors de-soldered from the board. So I pulled the soldering iron out and quickly fixed it. Putting the motor back together I was like "why did this happen?" the motor has a temp sensor, cool. But, if you look at the hall connector coming out of the controller there is nothing connected to the white wire coming from the motor. WTF! I bought this from the same vendor and they "set everything up", should've known better. Does the 72150 not have a temp sensor input? There is the option in the app to limit temp.
Anyway, the bike runs and the performance is lower than I expected. This is probably because I don't have a QS205 V3, which is what I'm going to get. Anybody have a good vendor? I was going to go to aliexpress and try and get a motor and maybe some spokes, then have the bike shop do the swap (hopefully). This is going to be an expensive upgrade, but the bike is so lame to ride right now I have to do it. There is no torque, and the motor is getting way too hot for the little bashing I've done (haven't even gone off road). I'm going to start the search for that tomorrow.
CALLING ALL SABVOTON USERS:
I'm trying to get re-gen setup on the bike and have enabled it in the app. I also saw that there is an e-brake function to enable. What does that do?
Also, If you let off the throttle the bike still keeps going. Example: I picked up the rear wheel and hit the throttle a little, the wheel should've stopped spinning after a few seconds letting off the throttle, but the motor kept spinning like the throttle was on.
I noticed when riding I, I was pulling like 2,500w then let off, then the screen still said 300w and I could feel the bike still moving a bit. Not sure whats going on here, but I don't like it, need to figure it out.
