do you think a quick refill would get you home? could use a pump, co2 cartridge,plus slime,. DONT WANT TO CHANGE TUBE ROADSIDE.
carry a small air tank or pump, in case of a flat?

A co2 cartridge won't do ?

What happens if he gets 10 flats on his way home
How many Flat tires/tyres will a standard co2 pump up.
I think the tube will be done if you get more than one or 2 flats on your way home. Ive found if i dont get of a flat straight away the tube rips to bits at the valve.
co2 is great and so is Slime.

When I explore beyond my usual commute I always pack a small 12V air compressor along with my tire patch kit/tools. Runs on lighting battery and makes any flat repair seem so much more civilized than a damn hand pump. There's some pretty small/compact units out there for little money.
One use devices like tanks or CO2 cartridges don't instill a lot of confidence and may or may not have enough capacity and pressure to properly seat the bead. Plus, it's always nice to stop and offer air to other bicycle riders fixing flat.

perhaps it is a silly question. but i'll repeat it anyway,
since i'm not going to try a roadside repair, is putting air or co2 into a tube with a leak likely to get you home? give me odds. 1 in 5? 1 in 3? 1 in 100? 50/50?
i don't have any flat experience. Just like cell balancing, i read about problems i never have, so i figure i should explore the topic.
thanks!

I'm sorry, 'can't answer - it all depends on the extent of breach of the tube/tire. But it's not likely to help much, if any.
IME/O - Slime or other tire sealant will usually reveal and often slow an air leak enough to reach some place of remedy.
btw, you don't need to remove the wheel to patch a tube....

That depends on how big the tire is, how fast the leak is, and how far home is.
Odds are, probably not.
100 lbs in a small bottle isn't going to fill a tire, unless it's a very small tire and you're going for very low pressure. the bottle can only fill until it and the tire are at the same pressure. And that pressure will depend on the tire + the bottle's total volume.
those CO2 canisters have thousands of pounds of pressure in them. If you carry 1, you can carry 2 or 3 almost as easy.

tire is 40 psi max, 2.25x20

Kind of a huge thing to graft onto the bike to address a rare need....Matt Gruber said:
To ask the obvious: Why not just carry a pump?
I have 2.35 Fat Franks and use a Topeak Turbo Morph. Fills them quick with little effort. I've fixed flats for others and pumped them up to 100lbs. Nice pump. It's big but clips horizontally out of sight under my luggage rack - and it's still tiny compared to your tank.
Mine is the previous model of this - more squared-off top.
It's a matter of personal preference, but a big one-use air tank would not even be on my list of choices for emergency gear...

I've got 2 pumps, looks like i'll try to find a power resistor to run 1 off 18v, instead of 12v.
Probably wasting my time, no bike flats in 20 years.

Not big enough tank for 100psi to do you much good.
Given the volume of the tank, and the weight, I'd rather carry an electric air pump to run off my traction pack. 
(I did actually carry one around that ran off my lighting pack for a while, but havne't had any flats in a long time now, so only carry a small PITA manual pump just-in-case-of-dire-emergency, plus a couple CO2 cartridges and the patch kit, all of which can be used without taking the wheel off the bike if I ever have to).
If you didn't have flats riding around on your bike before it was electric, you probably won't have them now either. If you did before, then you probably will now, but you could potentially fix that with preventive solutions like better tires/tubes/etc, depending on the causes of the problem.

I don't need such thing. I never have gotten a flat after the mod I did. Double layer with inner lining and thorn resistance inner tube with inner slime. Make sure the outer layer is tough and you are set! More than 7K miles combined on that design and never have gotten a flat running over many things.

I know you said you don't want to change a tire roadside, but honestly, that is the easiest option. I used to feel the same way as you. I put slime in all my tires, then one day I actually got a a small leak, and the slime did it's job, but also sprayed a tiny stream out of the hole. So, when I got home I had green slime all over the bike, my pants and shoes.
I decided I would just get better at changing tires. So, I stuck all the wrenches I needed, a small hand pump, and a few tubes in my seat post trunk and carried those around with me everywhere I went. After a few tries, I got really good at it and was able to change tubes in about 10 minutes. With this method, you are good to go with just 1 one repair. New tube, and you can ride till the next flat.
If you go your method you have to repair things 2 times. Once on the road with the CO2 then AGAIN once you get home to actually repair the damage.
Just practice (doesn't take long) then you only need to fix things once on the road.

I commute around 25 miles a day between Queens and Manhattan. I don't often get flats but it happens. Since I have 2 Ebikes with panniers, I pretty much carry whatever I want. So I have at least one spare tube, a few patches, and a hand pump and two CO2 cartridges.
When I get a flat, I first pump it up to see how quickly it loses air. Sometimes that's enough to get to work, or home. I might have to stop and pump it again. If i need to change the tube, it isn't a big deal on either of my ebikes although I do tend to get dirty hands. I guess if I cared about that I could carry gloves.
I like the idea of carrying a small electric pump, I hadn't thought about doing that. I'd have to figure out how to wire it to the battery though. That's for another thread I think.

OK, how about this? Say i carry just a pocket knife.
and i cut off the flat tire/tube.
can it go 2 miles 5-10 mph? (i plan to replace these Innova tires anyway, cheap flimsey knobbies)

No, but stuffing grass inside might work. It did for some kid who rode a 125 moto from South America years ago.
You mean ride on the bare rim? Probably not a good idea, as it could damage the rim, aside from it not having any traction.

well, it is not a tubeless rim, so it should be able to withstand some minor dents. if not, then it proves it needed a stronger rim anyway :wink:
i mean, u are riding along, at some point u realize the tire is flat. so if i just keep going, fine. if the tire/tube gets tangled up, then i cut it off.
in 2003 i thought i had a low tire in my 72 vette. 1/2 mile later i pull over, it had ZERO psi.
when i had a dirt track car, once i was doing laps, and BOTH inside tires went flat, and i didn't realize it for several laps.
so i kind of doubt i'd stop.
but i don't know about an ebike, that is the Q.
plenty of power, unlike a pedal bike.

Get Park Super patches and stop being a nanny about punctures.
It takes less that 4 minutes to find the hole, pull out the offending section, scuff and patch (self adhering, no glue to mess with). Stuff tire back and pump and ride. (CO2 can makes it possible to do in less than 4 minutes. If you have a hand pump, figure an extra 3 minutes pumping at least).
Of the 4 flats that I have had in the past 1.5 years, every single one was done in quick fashion as described above. I use tire liners (the weight is minimal on an ebike wheel) to reduce the chances of punctures and run a medium pressure on the tires. High pressures lead to more punctures and possible loss of traction (if too high). They also don't allow your tires to give you pneumatic suspension benefits if pumped too high. I'm running about 45-50psi in my tires rated for 60 psi at the top end.

some good reviews, some bad.
Thanks for the idea!
Do you guys think i should replace the tire/tubes on my 1999 Next bike? No problems 15 years, keep or replace? no cracks or wear problems, and never a flat!
