When it rains, it pours AHick :lol:
Pictures at the end of the post. Wire insulation burned overlapping inside the motor where I zip tied them, also wires got damage at axle entrance.

Stories
What happened today with the cracked frame, which I still rode.
+ 3 days ago I had a slow leak so I took old tube out and could not find the leak, pumped it figuring its good for an 20-30 minutes of riding, but did not seat the ta deep into its slot, so axle spun which bent the 1/4" steel plate ta, seated it back down but wasnt tight and still spun. I will get a picture of the ta. I couldnt use the power and pedaled 1-2km to the train, pair of cops were writing up people for no fare, I sit on the seat but fake walk (using slight throttle) when I am on the platforms, I had ear phones on and grooving, the one cop told me to get off the bike and I did, but he eyeballed me hard. Thankfully train came within 3 minutes while they were still busy.
The walked from my station was 3km home. I did not realize I had a adj wrench I could have used as a ta, if the small hose clamp would have fit, but it was a good workout.
+ 2 days ago I rode on a flat for 5km - Regular brand name tube is toast, tire doable but iffy so I changed the tire. This was during rush hour, no bikes allowed on train, had ear phones going and grooving hard, heard woman over PA pipe up, didnt listen figure it was about me and bikes at rush hour as it was 3:27pm, no bikes at rush hour is in place at 9am-10am or something and 3:30pm-6pm but already paid my $3.50 fare (good for 1.5hrs) so I'm getting on the train. :lol:
OK the newest story, todays story is, found cracked frame, riding back home 8km, battery was full so I knew I would be without e-wheels for awhile. Figured I'd drain both batteries down, so I did circles and crawled up a small 20 go arounds and its a sputter and a walk home, about 1km, but its a good workout.

How has your luck been lately? :lol:
I have a sensorless 36V 35A Greentime controller. But this just reminds me I have to work smarter not harder and install a temp sensor and get a controller that will accept it. I am thinking Phaserunner myself. However I have 36V battery and 52V battery so, controller lvc is an issue. I use it for the 36V battery, the 52V has a bms that cuts out at lvc.

With me it's usually Hall sensors I can toaste a rotor pretty good also. I just kind of turned down the amps a bit at 72 volt an aluminum stator.
A hub motor can run pretty good all toast it up brown and Rusty inside.
The broken frame isnt my half ass doing. BTW I am 291lbs today, it broke 3 or 4 days ago I felt a slight wobble, thought it was the hub. The battery on the rear rack is 36V 20Ah Ryobi.
No obvious smell from a slightly opened cover.
Opened it all the way up and the windings are shiny.
Just a slight caramel? smell same as before when I opened it up 2 months ago or so to replace stock wires with cheap hook up wire.
Good news, its the cheap ass wire I installed about 2-3 months ago. The wires were touching inside the motor where I had zip tied them out of the way they criss crossed.
When I was walking home I was moving the wire at the axle exit and half ass inspecting the rest of the wire thinking spun axle frayed the wire, it didnt.
Now its just a matter of what wire do I install, do I half ass it again :lol: No, but local store B&E Electronics doesnt sell good wire. May look at Grintechs selection, but ideally I'd buy PTFE Teflon from a guy in Cali I've bought from before, but can't find his web link. He sells guitar stuff, has 8awg and thinner ptfe teflon wire.
PPPPHHHHHHEEEEEEEEEEEEEEWWWWWWWWWWWWWWWWW
Oh and you can see the red wire at the axle entrance, interesting, thats what I originally thought.
I will have to come up with a solution for that axle entrance.
PS been riding with two ta's, just lost the other one. Spread drop outs not an issue, using large washers. I dont ride fast. Backing nut due to e-abs-low use is an issue.
