My Radrunner was terrible on bumps. At 30 PSI, those wide tires were stiffer than other tires at 60 PSI. A suspension post and seat with springs made little difference. A worse problem was that the handlebars were at belt height and not far ahead of my belt. That made my upper body unstable and...

In 2020 I bought a Radrunner after studying an EBR video that showed its performance. Mine was disappointing. I checked the specs: 750 W and 80 Nm. On a 10% grade I found that I was getting 2/3 of that torque. On a 6% grade I found I was getting 2/3 of that power. What's more, when I studied the...

In 2020 I discovered that my Radrunner was unrideable on mud or wet, sloping grass. In 2021 I discovered that it was uncontrollable on snow unless I reduced tire pressure to a third of the tire manufacturer's minimum. I began popping spokes because they had defective heads. I got 3 punctures...

I see you were standing on the pedals. A few weeks ago I did that to get home with a cracked seat post. I'd thought it would hardly matter since I normally ride with most of my weight on the pedals, a bit like walking. I hadn't anticipated being so unstable without my butt against the seat. I...

I don't ride in a desert, but the soil here contains plenty of silt, defined as 4 to 63 microns, and clay, defined as being under 4 microns. Gritty dust accumulates on windowsills behind screens. It accumulates on my car in the carport. My vacuum cleaner picks up a lot of mineral dust. For some...

Also, a beefier motor may have fatter wire, which will produce less heat. I don't know what gauges are used in e-bike motors, but if a 350 had 18 gauge and a 750 had 14 gauge, equal current would produce only 40% as much heat in the bigger motor. Back EMF, which reduces current, increases with...

I don't remove the chain to use Finish Line. The first time, when I'd ridden 14 months with oil, I used a paper towel to wipe off what oil and grit I could. Application took about 1 second on each side of each roller. The fluid looks clear on metal, but it caused black stuff to run out of the...

I had to replace maybe 4 spokes on the rear wheel of my Radrunner. In the photo, the heads had popped off where the holes are. I read that most breaks are near the threads or at the elbow. The broken heads were a mystery until I noted the sunken head between the holes. The head was too small...

I believe tension tools came along for very light road-bike spokes and rims, and even then, many mechanics go by feel. Adjusting by sound has worked for me with 4 e-bikes (including a Radrunner and a Radmission). I get the wheel off the ground and tap spokes with my spanner-style spoke wrench...

My Aventon chain looks like yours but with no rust. I get 150 to 300 miles per charge, so I guess I pedal harder than most. At 1,000 miles I checked the pitch. It's still slightly under 1/2 inch. On two chains whose rails looked like plain steel, I'd found that Finish Line Dry Lube, applied to...

It happened to me this year. If it's okay after cleaning but soon returns, the cause must be uneven deposits from the pads. With resin pads, I've found that dish liquid and water will clean a disc nicely. (One of these days I'll try water alone.) Heat causes a transfer from the pad surface to...

I thought my inseam was 30", but I measured and it's 9". Live and learn!

My legs aren't long enough to reach the ground. That's why I ride a bike with pedals several inches above the ground. Wannabe talls irk me, like Randy Newman, John Wayne, and Johnny Cash. I have it on good authority that in real life all were so darn short that they could ride bicycles wherever...

Measuring from the center of the axle to the ground gave me precisely the information I needed. That's easier than trying to roll exactly one revolution. The rest was checking, which showed that sensor error can be a much bigger problem than errors in diameter. The only mile markers around here...

My first e-bike had 20 x 3.3 tires. I didn't know what wheel size to tell my display. Rolling would have been inaccurate unless I used a carpenter's level to measure when a mark on the sidewall was directly below the axle. I simply measured from the center the axle to the pavement. I used mm...

He asked if we'd bought the correct one, and I believe I have. There are 6 possible ways to wire the three pins, so I didn't know what would work on my Aventon until I read that this one worked on an Aventure. It stands to reason that all Aventon controllers would use the same throttle wiring...

https://www.merriam-webster.com/dictionary/cruise%20control Throttle friction wouldn't give me a constant speed. The steepness of a hill changes even if it's not apparent. Besides, as I tire, I would slow if I didn't add a few watts of assistance. Friction in my replacement shifter was causing...

https://www.amazon.com/dp/B08LPGC63F This works great on my Abound. This is my shifter. There's ample clearance. https://www.amazon.com/gp/product/B0919764L5 I didn't like the torque sensor because the lowest setting gave me more boost than I usually wanted. Then the bearings began dragging a...
