Flat Free: Nexo and Ever Tires skip the pump for puncture proof riding

We all hate flats. Naturally, that has led a number of companies to research a flat free solution to our tire needs. Over the years we’ve seen solid rubber or foam tires, foam filled rubber tires, pneumatic tires with massive puncture protection strips, just about anything you could think of. In spite of the amount of attempts to get it just right, the team behind Ever Tires and Nexo Tires thinks that there is still room for improvement. That led them to create two entirely different flat free systems – Nexo and Ever Tires.

Sort of the bicycle equivalent of the Michelin Tweel (though without the flexible spoke section), the Ever tire promises a new take on puncture proof tires, though the Nexo tire system will bemore accessible due to the somewhat universal design…

Unlike many other flat proof systems we’ve seen, the Ever Tires use a hollow structure that is designed to add to the ride quality. Made from a solid material, this allows the tire to be completely flat free but still feel almost like a standard tire. According to Ever Tires, “most people can’t tell the difference” between these and a standard tire, though they’re not recommended for serious riders, or for aggressive riding in wet conditions.

The main drawback is that they are mechanically installed onto the rim, which means you have to buy them as a complete wheelset, not just a set of tires. Initially, the tires will be offered on complete wheels with aluminum single or double wall rims with stainless steel spokes. Hopefully taking the wheel weight into account, Ever Tires claims the whole system will run about a pound heavier than a set of pneumatic rims and tires (and tube). Available in 12, 16, 20, 24, 26, and 700x25c, wheelsets are sold with limited hub selection so double check your compatibility if you’re going to order a set.

If you’re not into replacing your whole wheel system, the other flat free option from the same team is the Nexo tire system. Where the Ever Tire is mechanically pressed into the rim, the Nexo tire can be installed by the user with their patented T-Bolt system. Each tire includes an installation kit with multiple width T-Bolts, and you pick the set that’s the correct width for your rim. Once the T-Bolts are chosen, you press them into the tire, and then install the tire onto the rim, locking each T-Bolt into place.

The Nexo tire is also solid (looking). Part of what sets this tire apart from previous flat free tires is their use of NEXELL polymer composite which is claimed to be a macromolecular material that is filled with tons of little pockets of Nitrogen gas. The pockets are small enough that even if you get a nail or something through the tire, it won’t affect the tire’s ride which is said to be good up to 5,000km. Compared to other foam tires such as EVA, NEXELL is said to better withstand heat, and have much better wear resistance and offer a ride closer to that of pneumatic tires.

Like the Ever Tire though, there are downsides. Rolling resistance is supposedly 15-20% more than a standard pneumatic tire, and the tire comes with the same warming about using caution in wet weather riding. The tires also carry a weight limit of 100kg (220lbs)

Offered in multiple sizes and colors, the Nexo Tires start out a bit cheaper than the Ever Tires at $75 for two tires and the installation kit. Wheels and tires for the Ever Tire system start at $76 for kids’ 12-16″ bikes, up to $105 for the 700x24c wheel and tire set. Shipping only to the U.S., both tire systems are currently past funding in a Kickstarter, with delivery expected for January 2017.

Snore, another kickstarter looking to replace a problem that doesn’t exist; with something the will inevitably heavier, have poor grip, high rolling resistance and costs significantly more than a set of puncture resistant tires. Changing a tube is one of the easiest on earth to do; and as long as the rider is not commuting on straight glass shards than the trade off is clearly not worth it. I ride ~9500 miles annually on Open Corsas and Schwlabe Ones and flats are the least of my mechanical issues. In fact the latex tubes on my race wheels actually outlasted my Bottom Bracket!

What are you talking about, “problem that doesn’t exist”? Punctures have been problem for cyclists since the invention of the pneumatic tire. Changing a tube isn’t hard, it’s just very annoying, and inconvenient when you’re in the middle of nowhere or on the way to work.

Maybe the problem exists (it does), but this is not the solution. These were invented out of existence twice, first over 160 years ago by Robert Thomson, then by Jim Dunlop. The ride is more important than an occasional flat. Keep your tires inflated, use puncture-resistant tires if you need to, and just deal with it.
This system looks obnoxious because of its permanent installation over the spokes. What does one do when they break a spoke, which will be inevitable with a solid tire transferring all that shock directly to the wheel.

The Nexo tire will go on the rims that you currently have, the Ever Tire is rim specific and we provide the rims. They are two different solutions for the problem of getting flats. From your comments sounds like Nexo would be a better fit. The big difference with either system is the materials we use and how they are installed, so while the concept of a tire that doesn’t get flat isn’t new our solution to the problem is different.

I love my tubeless tires but crap happens. If I had a commute to work of less than a 10 miles, or had a beater for commuting to school, I’d love to rock these things. I’m sure they ride well enough if your roads are in decent shape.

I ride about 12,000km per year and actually don’t mind dealing with a flat, except in the winter. If its pouring rain or freezing cold, not having to swap a tube at the side of the road, in the dark, is a huge attraction.

The folks who read Bikerumor are not the target market for these tires. This is for people who use their bikes for strictly practical purposes. Think day laborers and the working poor. See for instance: http://www.alternet.org/story/38776/l.a.’s_invisible_riders

Dirk is right…..the problem is the tires cost multiples of the bikes.

IMO, cheap, poor quality tyres have been a problem for cyclists since the invention of the pneumatic tire. That’s whay people get flats. 6000 km a year and the last puncture was in 2014.

If you’re riding 6000km a year, your experience as a cyclist is preventing more flats than your tire choice, I would bet.

Not known to me how these tires behave or handle as I have never ridden them. All I can say is that if they did work somewhat comparably to a regular tire I would buy them in an instant. I ride year round and flats are without a doubt the worst, most annoying thing in cycling. The thing I want is hard data, with side by side comparisons, in real life situations and conditions. If I owned this company I would be doing that over and over.

I do 20km x 200+ days a year on Gatorskins, I get a year out of them. I’ve had one flat in the last two years – given that I’m in the Pacific NW the ‘caution in the rain’ is a dealbreaker for me even discounting ride quality and the non-issue of 2 minutes of pain every 750-1000 days or so when I get a flat.

Gatorskins really suck in the rain. Go with 4 Seasons if you want a Conti tire that does well in the rain.

I’ve never had an issue with them in the rain. I run 32s at 90 PSI when it’s wet and they’re fine.

Do they make a tubular?
O snap, they already had this a century ago.

In my experience, the #1 cause of the average rider’s flats is caused by not having the tire inflated to the right pressure. It increases tire wear and resistance when riding over rough objects; increasing the chance of a flat.

Can confirm. Work in a bike shop. It’s ridiculous how many people don’t bother checking their tyres.

Long live the flat! I’ve been commuting, racing, and working in the cycling industry for over 20 years. Haha, I couldn’t tell you how many tubes I’ve put in bikes. Ride the appropriate tire for where and what you’re doing, keep em inflated, replace them as needed, and GET OVER IT!

You clearly don’t get it. You’re a cyclist, this is geared towards people that are not cyclists. Get off your d*mn high horse. Or bike.

so, seriously no one noticed the misspelled ‘Tiawan’ on their kickstarter page?
and by reading these comments, did y’all even READ their campaign page?
For products like these, the intended purpose is to get people riding more and more, consuming and buying, so the company can actually invest in this tech to make it better… think how fast disc brakes advanced once they were adopted in the MTB community.
i mean, dude….. if I had a tire that doesnt flat, last a long time, and isnt actually heavier than ‘heavy duty tire, tire liner and tube’ combo i would maybe think about it for my bar bike…. zero maintenance anyone? who wouldnt like that?!

if you are looking to put this on your go fast crit racer or something thats pushing the limits of grip and rolling resistance, you are a ____! 🙂

I wish all bike share bikes came stock with something like dis….

I need airless tire for fatbike, there are no producers at this time they can produce 26×4.0 airless fatbike tires?
