My Tire's Are Rotting !!??@$

[PCeBiker]

Looks to me like you have the tire on the wheel backwards.

It's a mirage.

The bike is upside-down standing on the seat and the handlebars.

It's right side up and on the wrong side of the road in Australia (I think you to pedal backwards in the land down under as well?? )

 

[Tars Tarkas]

Ah, right!

I read some years ago to never buy tires from a place where there is welding going is as it produces a gas that rots tires quickly.

 

[Gionnirocket]

@PCeBiker isn't welding exactly

 

[PCeBiker]

I guess it's possible that they were old stock and weren't properly stored before purchase.

I read some years ago to never buy tires from a place where there is welding going is as it produces a gas that rots tires quickly.

So, how do you properly store tires ??
Maybe a cold dark place like storing potatoes??
Maybe an oxygen free space filled with nitrogen so the rubber doesn't oxidize ?

I've gotta a huge bag of rubber bands that I keep in a zip lock bag in the fridge. I've probably had them 15 plus years and I'm almost out. But every time I take out a handful to replenish my daily use ones that are worn, they're like new.
So yes... Sealed in plastic and in a cool place. That's how I store my spare tubes as well.

I heard back from Schwalbe and he said that 8000 km at almost maximum pressure is all that could be expected from the tire, but I was given a 50% discount code for my next purchase.

I was thinking that higher pressure would mean longer tire life and more efficiency, but he said that I should be inflating to about 25 psi for my ~85 pound ebike and myself at ~165 pounds.

The two tires can support almost 700 pounds, so I was Way over inflated.


I'm thinking that I may have stretched the tire carcass with all that pressure and it started to peel?
Kinda like how spokes can stretch?
There was Very little wear of the tread itself.

I've got a full suspension ebike (with a double spring seat), so I figured I didn't need the tires to provide and suspension effect as long as they stay in contact with the road.

tire on the wheel backwards

That is so you can back out of a snow bank.

pedal backwards

I flipped a BB crank magnet wheel on a cadence sensor. It reversed the polarity so you could ghost pedal backwards at 28 and analog pedal forwards. The best of both worlds!

In LA in the '70's anything rubber would rot before your eyes. It was the ozone from the smog and UV. I wonder if they are parked next to a gas water heater or smoke VOC and the grow lights are doing the same thing.

I had this POS ebike for more than ten years before I realized that the PAS works, but only if you pedal backwards.

I never bothered to pedal it and just thought the PAS didn't work until last year when I was oiling the chain.
I was spinning the crank backwards and it started to go.
I never pedaled the ebike and just used the twist throttle.

I bought it used and someone tried to attach a PAS sensor to one of the cranks and cut away some plastic around the BB to install it.
I didn't know what the hell the thing was but I could tell it was broken so I just removed it.

So the ebike does have a PAS sensor somewhere and I guess that they replaced the controller and the new controller was expecting the PAS sensor was on the opposite crank?

I remember trying to google the controller to try and bypass the 25 kph governor but didn't have any luck.
The power kicks out at 22 kph and if it hits 25 kph, the regeneration kicks in automatically to slow you down.

In LA in the '70's anything rubber would rot before your eyes. It was the ozone from the smog and UV.

My uncle told me that back in the late 70's or early 80's, a truck load of smoke detectors was delivered to LA.

The whole truck load had to be sent back to the factory to have them detuned because they all went off as soon as you put a battery in it.

back in the late 70's

It was so bad that you couldn't see a huge hill a mile-and-half away. Plastic also rotted from the ozone. PE requirements made us run in it, burning. A new rubber band might last ten-days outside in the Summer.

On some bikes you can set Wheel Magnet Count. Set it at three and install two.

UCLA,..
When the smog clears..

I did think of trying to locate the PAS sensor to remove half the magnets, but I didn't pursue it.
I didn't even know what a PAS sensor was until 3 years ago.
There's no programming at all on the ebike.

And it's got a dummy gauge for a speedometer.
If you hold it at full throttle it will show the speed all the way to the ambiguous unmarked red zone.

It only goes 22 but it shows what is probably 25 kph. The brake switch turns the motor off, then the needle Instantaneously drops to 22 then the needle moves normally as the bike slows down.

That's probably why it doesn't have any odometer, because the speedometer tells Nothing But Lies !!@, so the odometer would have to lie as well.

The ebike is about 25 years old, but even back then they had AI type crap messing with the gauges.

My (now dead) car has the same type of dummy gauge for the temperature gauge.
The needle rises normally and stops at the half way mark as soon as the engine gets to normal operating temperature. Then the needle doesn't move until the engine is Way Too Hot.

It essentially became a warped head indicator.
If the needle rises above the halfway mark. Your cylinder head is warped.

I had a Porsche, Audi, VW dealer replace a temp valve backwards on a radiator thermostat. How is that even posable? Wouldn't there be a left/right tab or something so it only goes in one way, up? There is a magnet on a spoke counting rotations and calculating speed. Try removing it. I often have. Proven in years old posts. Yank speed sensor.

This is the thermostat for my car,..

I replaced it a couple times, and I think it won't even fit if you try and install it backwards?

The important thing it to install it with the jiggle pin at the top.
The thermostat mounts vertically at the bottom of the radiator, and the jiggle pin allows air bubbles to escape from the engine block into the radiator.

If the jiggle pin is at the bottom you could get an air lock in the engine, the water pump stops pumping, and you overheat.

I'm pretty sure that the sensor is inside the motor?
There's no magnets on the wheels.

It's a direct drive hub motor, so maybe the hal sensor data can be used directly to give speed data?

I don't really care anyway. The thing is a piece of junk.
I only do necessary maintenance on it.
I put new tubes and tires on it after I quit driving, because I needed to use it to get groceries, and just recently replaced a broken spoke before my wheel fell apart.
It was making a crunching clicking sound and was all warped to hell.

I was driving less than 800 km a year for the last 5-10 years that I had my car.

I got my first ebike almost 3 years ago and my second ebike 1½ ago and have put on over 12,000 km between the two of them.

I didn't "enjoy" driving, but I have fun on my ebike.

Water cooled VW/Audi thermostats do not live in the engine block like your picture shows. They are mounted in the cooling circuit next to, or are a part of, the water pump. On some models, it costs almost as much for the thermostat as the entire pump with thermostat. The water pumps have plastic impellers that crap out. It's only a matter of time before they do. The same design has been used for over a decade, but improvements haven't fixed anything. The aftermarket has made all-metal pumps, but they are expensive and still crap out. German engineering.

I remember that the PCV valve for my car, and almost any car, is available at Canadian Tire for ~$5, but the PCV valve for the Audi is only available from the dealer at over $70.

 

[Gionnirocket]

Audi is an impressive car but it's also 2 to 3 year car. Anything longer and you will pay dearly on repairs.

That sounds just like our rear shock??

I'm not going to bother rebuilding it when it craps out.
It's cheaper to just throw it out and buy a new one.

I used to live on a mountain top in the redwoods overlooking the Pacific. It sounds nice but I was car dependent. The closest town was 20 km round trip and to stock up at a decent price would be 140 km. Then I would sometimes just get in my car and drive, like to the upper Yukon, or to Bean-town and Maine. As an aside I didn't know that they play basketball so well at Yukon. I was averaging 1,500 km per week. Now I live in a place where everything is within a ten to fifteen minute bike ride, with good safe bike infrastructure. And I feel so much better. I sold my car in January of 2018 because of eBikes.
