it just occured to me yesterday when changing a flat on my bike that i needed a wrench to remove the rear wheel inner tube and put in the new tube. Normally i just remove the wheel by lossening the skewer and change the tube. But on an ebike, you have lossen the nut on the axles to remove the rear wheel. Do you guys just carry around a wrench just for that occassion?
how do you change tire flats on ebike?

Depends on if you can easily call someone to pick you up if you get a flat. If you can't then yea you need to
carry a wrench. It's possible to patch a tire while on the bike , but it's not as easy by a far measure.
Honestly though sometimes I forget to grab my wrench when I am out and about.

Cobra tubes by flybike.

I've never used them, they don't seem to come in the balloon sizes I run, but looks like a brilliant idea.

I put fat downhill tubes in my tires years ago. I have not had a flat since then.

I run 5x slime tube from walmart 10.99usd. in my rear hub. I think it dosn't help with balance. And a kevlar tire. You don't want to take off a rear wheel. And never a gaint rear cluster!uck rear hub.

I have a cobra tube. I have never used it. I hope I never do. But it comes with me. It appears that it will work. You also will need something to cut the old tube to remove it. Great idea....if it works.

If it's a simple puncture I just take the tube out of the tire on the bike, air it up to find hole and then patch it and put it back together and air it up.
Yes, but...I almost never have to deal with removing it because of *flats*, as I tend to break the wheel itself before I flat the tire. :lol: I more often have to take it off to straighten the rim enough to roll the wheel without the tire dragging on the frame.mvly said:

Give me a break guys seriously. 
I had many flats when I first started riding the ebike like one every six to eight hundred miles three in one day once. I don't ride on that road anymore so no more flats. I have found no good reason to remove a wheel to patch a tire ever unless of course it's a quick release. Lay the bike on it's side or upside down pull the tire off of one side of the rim, usually the side opposite the sprocket, pull the tube out of the tire and leave the tiny bit of it inside the frame. Find and patch the hole. Find the offending junk in the tire, pull it out, and put things back together. I helps to put a little air in the tube before you stick it back in the tire. Put the one side of the tire back on the rim pump it up and go. 5-10 minute job even for an old handicrepped guy like me. Yes, now and then you need a new tube or tire but not all that often and the new patch kits don't even need glue. So, a way easier and less expensive job just to patch.
Edit; I did leave enough slack in the wires to pull the motor loose tilt the axle out of the freewheel side of droupout so tubes and tires can be changed without to much trouble. Only pulled the wheel all the way off once to replace a bearing. Rewired while I was in there.

On the first long ride, I hit a speed bump and poof, flat tire. I had been away from bicycles so long, I forgot a wheel liner. 2 wraps of rubber tape and one wrap of plastic tape to keep the spoke holes from cutting through the tube. I also cut the stem off an old tube and put it in as a tire liner. So far so good.

What ever you try...to prevent flats...fate will come along and kick youin the ass sooner or later.
I ran the first 100 miles or so on my bike with any old scrap tyres and tubes I had in the workshop...
never a flat or any issues
I think to myself that I was running on borrowed time, so I bought new tyres, heavy d/hill tubes, tyre liners, and No Tubes slime for the tyre.
Within a week aI had my first pinch flat..split the tube on the way to work, it was a split so could not repair it. But even if it was a puncture it would have been difficult...so much tyre slime everywhere, I cold never had mad a patch stick.
Think I may get my one of those cylinder tubes as a get me home option. leave the wheel on, pop the tyre off, cut the old tube in half and remove and stick the cylinder back in
The way my wheel is fitted..I need a workshop and a good 40 minutes to remove the rear wheel, torque plates, rear rack mounts, phase wires etc..so these cylinder tubes look a good idea.. even as an emergency get me home

I carry a 21mm wrench in one of my panniers just in case. Also pack the tools to remove the torque arm. Motor connections clip apart easily enough.
I figure if the pedal power fixie kids can pack a wrench, why can't I?
I guess what I'm trying to say is, it's still a bicycle tire...no need to reinvent fixing a flat.

All depends on how easy it is to remove your wheel
I need to turn my bike upside down to remove rear wheel, and with the battery pack still in, it makes it very unstable when resting on handlebars and seat
But to do that, I first need to unclip Cycle analyst from bars too, to prevent damage to that, then remove the pack
I also left no external connections on my phase or hall wires, so I need to remove battery pack for that also to get access to those connections, then thread the connections out through the box, cut 5 cable ties, just to remove the motor wires
Then it turn the bike over, then the rack mounting bolts, torque plate pipe clips, rear derailleur amd finally the rear wheel
For me it is just too many tools and bits to carry to do on roadside
I would need
8mm, 10mm and 21mm spanners
4,5 and 6mm allen keys
Large flat blade screwdriver
Cutters for removing cable ties
New cable ties and 30mm stainless steel pipe clips
Stud lock
Plus the usual kit to repair the tube
I just ordered myself a pair of those cylinder tubes

There is another solution to the hassle of getting the rear wheel out, get rid of the frock motor

I never had to change anything, as soon as i realized how bitch it could be i installed anti-puncture tube and put inside an autorepair gel. I'm totally sure i had several punctures because i left home with the perfect air and i had to inflate at the first gas stop, nevertheless it self repaired and i didn't change anything so far.

Thank you so much for this thread! I got it. I got it! I finally got it. Christmas came early for me and Santa dropped it off a few hours ago:
I'd normally say, "I can't wait to use it!" but that's not the case this time. I hope I never have to use it. Good to know I have this available though. Wish I had it last time my trike's rear drive wheel punctured in the middle of a parade.
