So the Adidas 5 10 is a climbing shoe, and Adidas markets one version as a cycle shoe. That made me curious. I turned to Wikipedia. It says even touring cyclists used to strap their shoes into toe cages, which was inconvenient and dangerous. (My brother did that to race.) It says modern cycle...

Latex house paint. You can avoid overspray by using a roller. The best way to paint tires is to pour house paint into a dish pan, lower the bike until the tire is just off the bottom, and turn the wheel. Turn it slowly to avoid spattering and to let the paint get into all the nooks and crannies...

Bicycle thieves wouldn't be so darned sneaky if they didn't dread embarrassment. The fear of embarrassment can be a powerful deterrent even when there's no chance of being caught. :)

Manufactured silicone rubber products use peroxide or platinum curing. Peroxide curing requires an oven. I think platinum curing does, too.

It's silicone rubber applied like grease. I started using RTV in 1973 to protect antenna connectors exposed to salt spray. I think it was decades before I knew it meant Room Temperature Vulcanizing. Some of it is a very strong adhesive, and some is easier to remove...

I haven't had battery corrosion, but I have had moisture problems in a Radrunner controller. It was the lowest thing on the frame, lower than the bottom bracket. Sometimes I'd hit the throttle at a stop sign and get nothing. I'd jump off and run it across the intersection because a single-speed...

With a simple Hall Effect meter, if you want 10 times more sensitivity, you just wrap the amp conductor 10 times through the donut.

Holly couldn't afford a plane. He and Ricky Nelson and Eddie Cochran could afford bikes and rode together. Nelson and Cochran were murdered. The death of Holly and 3 others amounted at least to 1st degree manslaughter or 3rd degree murder and probably 1st degree murder. Before the transistor...

Deutchendorf rolls into Lubbock a year or two after Buddy Holly, also a pilot, died in an air crash. Coincidence? Holly had recently recorded "Think it Over," obviously written by a woman, who was obviously Vi Petty, a concert pianist. Listen to her bang on the keys! She was pretty damned mad...

https://www.amazon.com/DROK-Capacity-Voltmeter-Multimeter-Shielded/dp/B08HP5VD4M In 1879, 24 y-o Edwin Hall discovered that he could count watt hours without cutting the wires from his e-bike battery. :)

It reminds me of the way a technician might pick up a resistor with insulated pliers and warn laymen to stand back because it was 33,000 ohms. :rolleyes:

My voltages are for a 48 volt nominal battery. If it reads 58.4 with the charger on, it's fully charged. When you shut off the charger, it's 54.4. It stays pretty close to that all the way down to 20%.

So you installed a shunt. I don't feel so bold! It looks like 750 micro-ohms. I imagine the resistance could easily vary by a lot of micro-ohms. That meter is going to lie to you and laugh at you when you aren't looking!

LiFePO charges up to 58.4, is fully charged at 54.4, and is down to 20% at 51.

It's advertised at plus or minus 1%. A lot of cheap stuff is accurate these days. It was only a few years ago that I learned that modern clamp-on meters can measure DC amps. I bought one and discovered that my 12 hp mower takes a lot more cranking amps than my car. That's because the mower is...

How come your displayed watts aren't the product of displayed volts and displayed amps?

Hall effect: I'm tempted... https://www.amazon.com/bayite-Waterproof-Display-Voltmeter-Transformer/dp/B0BFJ5NV5L My Radpower bikes would run down with the controller off unless I switched off the battery with the key. My Aventon battery can't be switched off with a key. It switches itself off...

Ahh... I see them on Amazon for golf carts. I wonder if they contain zeners. If they show voltage while the cart is on a charger, I wonder why they don't draw current whenever battery voltage is above the minimum. The instrument panel of my 1984 Nissan had a 10 to 16 volt gauge. I think the...

@PCeBiker The great thing about an analog meter is that the info doesn't have to go through the part of the brain that reads numbers. It's good for seeing at a glance and for catching quick changes. I'm tempted to put one on my bike to see voltage dips when I open the throttle. The size of the...
