My first two e-bikes had one speed. I used the motor on hills and to get underway. Then I got a 7-speed. Lately, I've been riding it as a regular bike most of the time. Since my last charge, I've been 260 miles and the display says it's at 76%. Motor assistance is still a nice option if I'm in a...

Except rear axle nuts, every fastener on my Aventon bike has a hex socket, but the supplied folding hex key set is terrible. More than 50 years ago, I discovered that the ISO hex keys that came with BMW motorcycles took the guesswork out of torquing, so I ordered a complete set. The H4, H5, H6...

You said when mechanics tightened by feel, the results weren't good. How did they check? Unfastening a bolt wouldn't tell because you'd have to overcome static friction. Nobody had mentioned ISO hex keys, but now you seem to be saying they were testing hex keys. If I were a Quality Engineer at...

I like a beam wrench because it's reliable. However, it's not precise; that is, reading the pointer is not exact. A clicking wrench is precise but could be inaccurate (unreliable). Last year I bought a set of 7 calibration weights which I could use for 1g, 188g, and 124 points between. I...

They're all supposed to seal. Schrader had been making pneumatic valves (for applications like life preservers and diving equipment) for decades when the Michelins demonstrated the inner tube. Unlike the Presta, his valve was designed for inner tubes. A year later, he patented the sealing cap as...

Sand or water will be thrown on a tangent to the tire. Four years ago, I got tired of how high the front tire of my Radrunner would throw grit and water on wet pavement. I bought a stack of polypropylene cutting boards from Amazon. They're like pace mats, 1mm thick. Polypropylene can be shaped...

All my motorcycles had externally threaded metal Schrader stems. I put tubes like that on one e-bike. To me, the advantage is that it's easier to press on a chuck when the tube is deflated. The other day, after mowing on an old rider, I noticed that the rubber Schrader stem on a front wheel...

I was at Vassar College in 1953. Every day, Danny Kaye would slip in to entertain several of us kids. He'd sing "Wonderful, wonderful Copenhagen." I didn't know what Copenhagen was until 1971. In a bar in Haynes Alaska I was drinking with an lumberjack who pulled out a can and took a pinch. I...

Ten years ago I had a Nissan whose lug bolts required 60 ft pounds. When it came back from a shop, I needed approximately 250 foot pounds to unscrew them. The mechanic was concerned with speed. He wanted to be sure they didn't come loose. As long as he didn't strip the bolts or snap them off, it...

I've had 3 e-bikes at once, but seemed to me that on 29 days a month, a stand would just be in my way. I don't even need a step stool to reach the rafters in my carport. That made suspension the obvious choice. I bought these. https://www.amazon.com/dp/B07FX6L3NN For each end of the bike, I used...

I don't believe the lumens figure. That's the whole amount of light. Mine advertises a 1.5 amp hour battery (about 5.4 watt hours) and 4 hours on high. That would be about 1.35 watts. I think an efficient LED produces about 100 lumens per watt, so it might produce 135 lumens on high and 68 on...

This is new to me. With the charger off, I guess it sparked because of a capacitor in the charger. Apparently, antispark connectors have a resistor path make contact before the zero-ohm path.

@harryS posted a link saying anything over 450 watts would cook that motor. Suppose you shift to a gear to let it spin fast enough to be 80% efficient. That's 360 watts of mechanical output. Suppose you can maintain 100 watts on the pedals. You've got 460 mechanical watts to take you up the...

I'm familiar with that with hub motors. If the motor is in good shape, it can escape notice. I may have had my first e-bike a year before I noticed. I don't get it pushing forward because the motor clutch doesn't engage. I think your motor would work the same way. If yours is bad enough that...

If Branson hadn't come along, those old ladies might have been swept out to sea on the rip tide!

Mine's a 2-prong, too! I should pay better attention. It's an NEMA 1-15 plug. When grounded plugs came out, the NEMA standard was the 5-15, as pictured. The 15 means a 15 amp limit. Harvey Hubble invented the plug with two parallel blades in 1910. Before there was a manufacturer's code, a...

https://www.amazon.com/dp/B0B2JT918P These are my latest headlamps. A row of lights on the side serves as a state-of-charge indicator. A long press to turn it off sets it to come on at that setting when next pressed. I'm ambivalent about the motion sensor because sometimes it comes on or off...

Me too, though I hesitated to mention it lest I expose myself as a snob. Oh, BTW, I paid $69 for mine. "If you have to ask how much, you probably can't afford it." :cool:
