I'm critical of my Radrunner, but I remember something I loved about it. With 3.3" tires at the recommended 30 PSI, steering was neutral. That is, it felt the same whether the bike was going straight or turning. When you lean, the front contact patch moves to that side. The drag steers the wheel...

When i got into e-bikes, I noticed how slow and cumbersome it is to stop at a stop sign. This was particularly true for my first two e-bikes. They were single speed, and for safety, their controllers provided little torque from a stop. It was not only inconvenient but dangerous because getting...

Nine years ago I bought a 14 A electric chainsaw. It still cuts fast. A couple of years ago, a neighbor wasn't making headway with his gas saw. The teeth were very dull. I brought mine over. Because of a design flaw, it would leak until the oil tank was empty while sitting on a shelf. So I'd...

I found a rubber lug-nut cap on the street. At 18mm, it fits both my bikes. Amazon has 18mm caps for certain VWs. They're $5 for a box of 20. The one I found sticks out 27mm, while the VW ones stick out only 20mm, which should be plenty for a bike.

A man wrote me an estimate this afternoon. He said my carbon copy was faint and offered me a picture. He sent it from his phone to mine. I asked if he could email it so I'd have it on my Mac. It didn't arrive. I guess he got my email address wrong. How can I email an Android text attachment?

Aventon seems to be going to 36 volts. There must be advantages. Maybe it could prevent users from getting far more than legal power with an aftermarket controller. Maybe a 36 volt battery is easier for a controller to keep equalized. Anyone know why Aventon is reducing voltage?

My Radrunner ( 20 x 3.3” semi knobby) was a big disappointment on snow and ice. It wanted to float on a loose surface. It wouldn’t even steer until I reduced pressure from the mandated 30 psi to 10. At that point, rolling resistance was horrific. This is my third winter with my Abound (20 x...

With my new seat angle, I may not use any motor during an hour's ride. With the controller idle except to power the display, the battery drains faster than expected. With no lights, the battery loses about 1% per hour of riding, or 6.8 Watts. With the head and tail light, it loses about 1.7% per...

Last summer, I'd ridden my Abound daily for 20 months when I removed the center stand to clean and lube. Bolting it back on, I crushed the rear light cable. I e-mailed customer service to ask the price of a new tail light. I got a quick response saying a new headlight, listing for $6, had been...

I replaced the controller on my Aventon Abound. Generally, I find e-bike connectors difficult to disconnect, and this was especially bad. Vaguely I remembered a tool. Later I remembered what it was: my hose removal pliers. Using them might require me to put some sort of hose clamp on each half...

I’ve had my Aventon Abound nearly 2 years. Sometimes there was a creak that seemed to come from the hinge of the fold-down steering stem. Lubing didn’t fix it permanently. Recently it got worse. I couldn’t tell if it was coming from the steering head, the boxy down tube, the battery in the...

I removed the center stand from my Abound. It's wonderfully made. I thought pulling the hinge pin would be asking for trouble, so I brushed it off and sprayed moving parts with silicone, and it works better than new. I turned on my headlight at sundown so drivers would see me coming. When I got...

After I worked on my Abound, the handlebars felt misaligned. I'd always found aligning ebike handlebars a hassle. This one was especially bad. From behind the handlebars, the wide battery box hid the wheel. Handlebars were adjusted by turning the stem, but loosening the pinch clamp allowed the...

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...

A couple of weeks ago I bought these. https://www.amazon.com/dp/B07TS6KCXD I'd always used the kind where you figure out what gauge wire you have, find the notch in the strippers, use one size bigger if the wire is stranded, clamp the wire with the sharp hole, turn the stripper to be sure the...

As of 1990, the Chinese owned more than one bicycle per household. These days, 4 times more e-bikes are sold in China than in the rest of the world combined. Chinese cyclists must know the importance of proper tightening of fasteners. Traditionally, bicycle manufacturers provided sheet-metal...

Airing bicycle tires was a hassle. On a car or truck, the valve will be nearly a foot off the ground even at 6 o'clock. With one hand, I could shove the chuck hard to seat it. On a bicycle, shoving hard with one hand will move the wheel unless it's at 6 o'clock, which is very low. Sitting on the...

In “Thunder Road,” a pretty girl is sitting with her beau when she hears a distinctive sound a mile away. She says, “That’s Luke!” She runs to the parking lot and greets him by opening the door and jumping in. The beau moans, “Nobody can compete with him. He’s got the loudest pipes in the...
