Third flat on the bicycle in 17,869 miles.

Yesterday, I had my third (bicycle) flat tire out on the road, in 17,869 miles. It was a drywall screw, and the tire was flat (700x25)in about a half a second. I live on the edge of town, and I was a little over 3 miles from home. I was finishing up on what would have been a 16 mile ride and was on pace to get it done in around 53 minutes.

Could have walked it, but not so much in cleats. I had a spare tube, levers, and CO2 cartridges on me. I could have replaced the tube along the road... but didn't really want to dive into that. Just wasn't in the mood, if I didn't have to.

Called my next door neighbor, he already had his hands full and couldn't fetch me for about an hour. Unfortunately, he had just driven by exactly where I was standing, only 15 minutes earlier. Couldn't reach other neighbor at all, but he is very hard of hearing... likely didn't even hear the phone. Didn't want to call my sister while she was at work.

So, pulled up the Lyft app on my phone for the first time in my life. I had installed it on my phone for this very reason.

Of course, the app automatically knew where I was, even though I was out in the country and not near a house or anything. Typed in my home address for destination. Chose an "XL" vehicle, and was quoted $16.04, and someone would pick me up in 9 minutes. There's a no-brainer right there. Paid for the ride and relaxed for a while... but wondering if someone would really drive out in the country to pick someone up.

Guy shows up on time in a GMC Yukon SUV. I saw him coming from a mile away. Slid my bicycle in the back and hopped in. And of course, I'm in my full cycling kit (helmet, glasses, gloves, jersey, bibs, and cleats) and not street clothes. Felt a little stupid, but it is what it is. 6 minutes later, and I was back home.

After using Lyft, I'm starting to wonder why I even bother carrying a spare tube, levers, and CO2 cartridges on the bike with me.

First flat was a jagged little scrap of sheet metal that the front tire kicked up, and then it tore into the back tire (tire was ruined), so I was done. Second flat was a single strand of a steel cable. And the third was a drywall screw.

That's a legit reason to let a random guy drive you home.
I felt it was safer than a random stranger pulling off of the road and offering me a ride. At least it would be documented on my phone as to who Lyft sent to get me home.... name, vehicle description, and license plate number.

I did joke with the driver about getting into a vehicle with a complete stranger, he said he hears it a lot. He also said that they are allowed to transport kids as young as 12 years old with the proper paperwork on file from the parent/guardian.

A flat bicycle tire every 6,000 miles? How do you do it?

Flats were frequent when I rode regularly.
Honestly, I've had four flats/punctures... all on the rear tire. But one of them was discovered in the garage, and was only a slow leak.
I don't count it because it didn't leave me "out on the road" and it was only losing about 10 pounds of air a day.
It was the tiniest sliver of metal that made it through the tire, and put a hole in the tube that was about the size of the tip of a sewing needle.
 
I used to get a lot of flats - A LOT - when I lived in Peoria IL and they used cinders on the road in the winter instead of salt. Tiny, razor-like shards which would embed themselves in the tire and eventually puncture the inner tube. No phones back then so I had to either fix it on the side of the road.... Or walk. The worst part of it is the cinders were not washed away like the salt was so it was a year-round hazard.
 
I agree. This guy is getting very few flat tries.
There are some indoor miles included that figure. About 20% of my miles are on a trainer.
As much as I would prefer riding outside every day, it just isn't possible in Illinois...especially in December, January and February.

Have you ever used slime in your bike inner tubes? It really does seal small punctures quickly. The only downside is that you have to keep the tires from going flat. Might be worth your time.
 
On one 30 mile ride I managed to get 3 flats... I started carrying 3 not 2 spare tubes after that. I'm impressed at your luck!

On one ride, I popped the rear. I got that fixed, started riding, thought to myself, I don't think I've ever had a front go... yeah, stupid me, the thought barely went through my head before I realized I needed to change the front too.
 
FWIW, I ride about 5k miles per year, mix of trail & road, and average about 1 flat per year. The MTB has tubeless with sealant, the road bike has Conti GP5000 clinchers with latex tubes.

Back in the 1980s flats were way more common. On the road bike, I'd get a flat around once per week. MTB wasn't any better back in the day, before tubeless if you pumped up the tires high enough to avoid pinch flats, you got no traction - choose your poison. Tire tech has come a looong way over the years.

As for hitching a ride with Lyft/Uber, my concern would be getting a car that can fit my bike. Even an SUV won't necessarily fit it, and even if it does the driver might not want my bike in the car, nor my sweaty self stinking up his seat.
 
I've been doing like 5 flats a year lately, around 2kmiles/summer. Being fat hasn't helped; my road bike won't take a wider than 28mm tire and it doesn't have to drop much in pressure to pinch flat it--and since I often ride dirt roads with it, doesn't take much of a rock at speed either. I should get a new bike as I'm seeing less and less of the stuff I wind up hitting (not paying attention--looking at scenery--or just not seeing it in time).

I need to check my can of bug spray, sometimes flats happen where it's rather buggy.
 
They are supposed to sweep cinders off the road in the off season, lol

Amazing that you can put 17k miles on a bike and have only 3 flats!

As a kids, we used to get flats all the time. We would go mountain biking and ride through the forest but we also got flats just as often in the burbs though. This was on an el cheapo huffy, mountain bike so bottom of the barrell hardware sure didn't help. Most of the time the tires were almost bald because our pockets were empty, it didn't matter, we still had fun! We got pretty good at patching tubes as kids.
 
Something that I have considered doing on my bicycle tires:

Clean inside of the tire very well. When fully dry, apply double sided 3M VHB tape to inside of the tire. Take either strips of heavy/thicker S glass fiber cloth or kevlar/para-aramid fabric and apply to the other side of the tape. Let it cure.

Then take 100% silicone caulk or RTV and thin it just a bit (I like naphtha) and apply that to the top of the fiber reinforcement cloth. If you want up the reinforcement, before you do that step, buy some methylcellulose powder (made of mostly crystalline micro and some nano cellulose, which is very strong stuff). Carbonize that powder under very low oxygen conditions (this creates something akin to more nature closer carbon nanotubes).

Mix some of that powder with the silicone+solvent and then apply to the fiber reinforcement cloth. Wait for everything to cure.

Then run a bit of Slime or similar sealant (would suggest Flat Out more so) in your bike's tube. Yes, all this will add weight, but should severely reduce incidences of stopping due to punctures.
