I think the biggest one for me was a remote horn.

I thought it would be great for city riding, since it was loud and could also be used as a car alarm, but for my bike.

Unfortunately, it suffers the same fate as the wireless dropper post in the article- a bad rubber band that moves, and extremely poor battery life. I think it’s accelerometer or whatever it uses for motion detection in car alarm mode drains the battery.

Also, to make matters worse, no pedestrians or other cyclists with airpods in can hear you approach. Though this is also the same with my car horn and air pods, so I’m not sure why I’m surprised. Airpod users certainly are when they ride though a blind curve tunnel and can’t hear the horn that is as loud as a motorcycle horn.

The unexpected Ws- a rearview mirror for my city bike, and a suspension seatpost from Suntour. You can see cars and bikes overtaking you from behind for the former, the latter is great on a rigid bike with no suspension.

Omg I had those same pedals. They came on my first BMX bike and I slipped off and destroyed my shins so many times. I didn’t know better as a kid, thought it was a me problem! I wonder how much better of a time I’d of had if I could identify and communicate the problem.

I have titanium or aluminum bolts in some select locatitons where even stainless bolts rusted out more than once. That’s on my snow bike which takes a huge wet salt beating every year though. None have broken so far in actual use but I did snap some initially from not using a torque wrench and going too tight.
