If I could I would give 10 stars! This was by far the best video. I got a small finishing nail in the rear tire and then Uber home. Looked on line and ordered new tubes and saw the Tannus ad and bought both on Amazon. I got to where I had the tube and liner in and got stuck with how to get the bead in. I went back and watched the video and it said I needed a smaller tube and cut the liner. I was about to go through the roof! THIS VIDEO WAS THE PERFECT FIND AND EASY! You still made it look easier. Thanks man!
Thanks for this video. I managed to do this install on my RadExpand 5 without a stand, and by myself thanks to your video, despite being a total noob. I took advantage of the metal guard in the bottom middle of the bike as a fulcrum, and some heavy objects as support and counterweight. A bonus of these inserts is the ride quality is noticeably nicer due to the lower air pressure needed in the tires, and the foam insulation.
When you hold up the wheel with one hand to start the axle nuts with the other, I'd run a short bungee cord through the rim and hook it up to the rack, or a longer one to the stem for the front wheel. That would free up the first hand for any fiddly work.
While the tire liners are a matter of choice, this video provides a valuable demonstration of getting the back wheel off and back on for any purpose. (flat repair, changing brake pads, replacing chain, etc.). We are still at a point where many bike shops don’t want to work on e-bikes they don’t sell. Thus, RAD owners should be willing to do a bit of basic maintenance, and fine videos like this are an invaluable aid for many owners. Also, it was good to see this fairly heavy bike up an a work stand, instead of upside down on the floor. A question though: Is getting the bike upon the stand a two person job?
I was able to do this job by myself (total noob) on my RadExpand 5 without a stand or being placed upside down, by using an elevated step/block under the center of the bike where the metal guard sticks out as a balancing point/fulcrum. Just have to secure at least one side with something decently heavy, I used a workout bench and a 25 lbs kettle bell on the other end connected by some straps as a counterweight.
i have the tannus installed in my rad expand 20x4 tires. The rad shop said to air up 18lb psi well i called the tannus co and they told me to air up to 2# less than the tire pressure recommended on the tire which is 30#. So that being the k do they gave i aired up to 27# also a small amount of air leaks out of the rear tire so i check every day before ride. So question is is there a reason you are airing 25# because of knowledge or is it just a guess. I watch all your videos, thank you for that,
i have a 20x4.0 rim but can a 20x3.0 innertube fit and work for a 20x4.0 ? Lets say if i don"t have a 20x4.0 innertube can a 20x3.0 be a substitute ? My next question is what if i have 20x4.0 inserts can a 20x3.0 innertube fit inside a 20x4.0 inserts ? if so what will be the psi to fill the tire up ?
I don't like using sealant in tubes. Over the years, I've changed out 100's of flats that had slime in the tubes. It can work for small holes, but Tannus also works for small holes, without the mess.
Hey great video….. a couple of questions I know you like the Tannus Armour however a lot of people go with the Flatout or Slime and one post even changed to a 3.3 inch tire with a 4 in tube and said it resolved his flat issues. Wondering your thoughts maybe even a good subject for a video? Also do you recommend any certain brand of tubes and or tire for the Expand5……. thanks in advance
Thanks Owen. I prefer going after flat prevention rather than flat repair. Keep in mind that the sealant is trying to repair a tube, not a tire, and tubes expand, as do the holes in them. No matter what you try, you can still get a flat if you run over something big and sharp. Tannus is just less mess and still usable if you do get a puncture. As for tires, what you want to look for in toughness is the tpi. Tougher tires will usually be 120 tpi which is threads per inch. For ebikes I like at least 120 tpi tires. But they cost more. Most brands will offer tires that are the same size but have different tpi's. Shoot for 120
Hi I’m thinking if adding the freewheel on my rad expand 5 but I’m in the uk and I have the 250 watt motor will it make a lot of difference what I mean is when I get into top gear it seems that I need another gear especially on the hills and on the flat
Hi and THANKS very much for the super helpful video's! I just purchased a RAD Expand5, first ebike ever, so far so good. Question though, in the RAD Owners Manual (Canadian version, page 61) it says "built-in flat preventative tire liners, like those that come with your RadExpand" - so do I still need the additional Tannas product?
Great question, most tires these days have some form of kevlar belt inside, but they overhype it. I like knowing that the Tannus are in there. It adds another layer inside the tires and the tires themselves will start to wear down over time, but when you need new tires, you can still transfer the same Tannus inserts into the new tires. So once you have them, you are good for the life of the bike! Nothing works 100% of the time, but the tougher the better 👍
Hi Bailey, sometimes the axle can get twisted in the dropouts. Try using a crescent wrench on the axle of the wheel a see if you can get it turn. It helps to look at it to see which direction to turn it. I should have covered this is the video. If you look at the axle you'll see that it's flat on 2 sides, this can get twisted a little in the dropout of the frame and not allow the wheel to come out. Use the crescent wrench on these flat sides of the axle.
I've had good luck with them. Nothing stops every flat. I've had 2 flats in the last 12,000 miles using Tannus. 1 was a big chunk of glass. The other was a box staple that finally pushed it's way through. Remarkably, they were 12 hours apart. The glass left a hole in the tire so big that without the Tannus, the tire would have been useless. With the Tannus, I road on that tire for another 1500 miles. There's pictures in my article -- pedalwithpower.com/tannus-armour-review/
If you have any issues trying to install these, let me know in the comments and I will do my best to help 👍

Great job! Yep, lower pressure is nice

great tutorial, you should explain that having the tube a bit inflated really helps, much easier than installing a completely flat tube
I tried to show that the tube was still partially inflated when I was re-installing it. I could have mentioned it better though

Good idea.Was the kettle waiting outside ?😊

Great Video 👍🏾
I'd this worth getting, will it stop screws?
Get Tannus armour pls Flat Out on the rear, and you're good to go. The front tire just Flat Out. Thank me in 2 years if you're puncture free..:D
Chris, is this better than slime or other things like that?
Did you reinflate the tires to the same pressure that they were at before the armor inserts?
I run mine around 23 psi
i have a 20x4.0 rim but can a 20x3.0 innertube fit and work for a 20x4.0 ? Lets say if i don"t have a 20x4.0 innertube can a 20x3.0 be a substitute ?

I thought you had to use smaller tubes for those installs
You can use smaller tubes, but you don't have to. I reuse the original tubes all the time. Saves waste
Do you recommend using tire sealant such as Slime?
I don't like using sealant in tubes. Over the years, I've changed out 100's of flats that had slime in the tubes. It can work for small holes, but Tannus also works for small holes, without the mess.

Hey nice video!
if I have tires measuring 20x4 1/4 (97-406) which tannus do you recommend?

I switched out mine and it does help

Hi how much does the Tannus armour cost for a Radexpand5 cheers
Check the links in the video description for current price. I think they are about $60 each
Can you use original tube or do you have to get a smaller one?
smaller one usually
my tyre was wobbly when I installed mine. was a bumpy ride lol.
What if I’ve followed all the steps and I still can’t get the tire off! I’m stuck at the “just wiggle it off” part 😂

From what I have seen in other video's these inserts don't work well.
