Die Trek Batterien halten erfahrungsgemäß nicht sehr lange, 11 Jahre ist maßlos übertrieben. Oft waren es nur 2-3 Jahre, was sehr wenig ist. Öffnet man diese Akkus wird man sehen wie die Schweißpunkte an den Einzelzellen gesetzt wurden oder dass die Zellen mittels Klebepistole fixiert wurden, anders als bei anderen Herstellern, z.B.

The only drawback of Nuvinci is it's fairly small gear range (380% on Nuvinci N380). While with a derailleur you can have 600% (on a 3×10 drivetrain) gear range.
If there was a nuvinci hub that doesn’t need to be attached to the tire that could be mounted on tricycles that had a gear hub between the axle and pedals I’d definitely get this product and install it as my gear system for my adult pedal car, my 4 wheel ebike whatever you want to call it cause this would be awesome
why adding new technology to something that is perfectly fine the way it is. an average person can learn how to shift gears in a minute.. if you make bikes get faster the risk of accidents increases too. if you increase how effective they are, you reduce the force needed to ride them. but they are supposed to make you use some force, thats why its considered a healthy sport. don’t see the need to spend more money for such “improvements”. if im to lazy for a normal bike one day, i buy a motorbike. Edit: if you want to improve something on bikes, improve their lifespan (no rust, stronger chain no flat tires,...). but that wouldn’t bring much profit, wouldn’t it?
The NuVinci N380 CVT requires little to no maintenance and won't get clogged full of dirt and mud. Paired with a Gates carbon belt drive, my bike is bullet proof... I no longer have to worry about my derailleur becoming tangled in the brush or damaged from hitting something. No need to lube chains anymore, because I am running a belt drive. Just a quick pressure wash, after riding and I am done. I spend a lot more time riding now, then I have ever... Due to the lack or need for maintenance on my bike. Cost for the whole setup was less then the cost for quality gear sets, about $700 all in.
I have never been able to figure out all of the gears on a derailleur system, that's why I ride a fixed wheel bike, which is great, because I have never been able to figure out all of those brakes either.
I've seen where the 380, under continuous load, like going uphill, will start to overheat. The impact will be that the wheel will stop free wheeling, meaning, if you got off the bike and turned the wheel by hand, it acts as though the brakes are partially on. The internal parts starts to overhead.
Very nice, but NOT an "infinite" number of gears, as the salesman stated. I'd love to see the internal mechanism. I drafted a patent application for a seamless planetary geared shift system that is also within the hub and COMPLETELY mechanical (no sensors whatsoever). This NuVinci invention seems to be able to adjust how fast (or hard?) one pedals before shifting to the next gear - impressive, but probably requires a sensor and thus a battery.
Let's just say that this gearbox is very different from what you describe. First of all it doesn't use gears, and it's not a automatic transmission in it's base form. I'm not even going to try and describe it but point you to this video: th-cam.com/video/vGs1nrXaZsA/w-d-xo.html As I see it there are things about it that I'm not enthusiastic about, such as the friction between the planets and the drive surfaces, or whatever you should call them. Until we know how it stands up to long term use I'll stay a skeptic.
Thanks Blahorag ! With the invention I mentioned, there is no need to shift ... in fact YOU can't. It's totally automatic. I think you have a good point about wear, etc. as it seems the Co never came to market with the product. It's a shame because it's fantastic (I rode a prototype). Enjoy your rides bro !
I am the original designer of what is being promoted here as the Davinci CVP gear hub. It will be found to be a very robust and reliable gear hub. My questions are: How did my design material for this hub get to the US... and by who?
First of all if what you say is true, you do have a patent on it don't you,if not sorry but it's your own stupidity(no offense).....but if you do ,i would sue the hell out of them,and if you have the patent ANY lawyer will take your case cause it would be a slam dunk.
Can these Travoy with the rack mount be installed on an etrike. I usually travel about 17-35mph. I was told all the other trailers are limited to 15mph. I don't know anyone who does long distance touring at a max speed of 15mph. Hills are meant to accelerate up to 35+ mph.
CVT's in general have massive advantage over geared transmissions because they allow an engine to stay in the power band regardless of wheel speed. The Williams-Renault CVT-equipped F1 car was so set to dominate the league before it was banned in 1994.
I'm about to order one of these. Here's a HUGE selling point worth mentioning. If you commute by combination of bike and bus, you won't be able to load a large cargo bike or a traditional bike trailer on the front of the bus. And most cargo trailers are too large to bring into a crowded bus. The Travoy allows the bike to be loaded in front and the trailer to be rolled in like a large suitcase and remain upright. Something to consider.
What an interesting concept and implementation. I am always amazed by the ability of product design engineers to dream up new technologies. After having driven clunky Shimanos for life, I had almost given up on this being a possibility. Would love to try this out. Kudos to the developers.
Where's a safe place to buy used ones i good condition from?
Does it come assembled?
*I love the **Latest.Bike** I use it when going camping. It folds up so easy and isn’t heavy at all. Rides so smooth. I love my bike!*
what is the lowest and highest gear ratio?

Ko bhi videsi bike(Cycle) ho main usse acchi aur ball-bearing ukt smooth running bike Bana Dunga.
I like this. However, it appears like one has to turn the grip a too wide angle from the min to max gear. This need to be reduced.

Gabe cute or whateva
I hope to oder one of these off amozon next month but I wish the bags for it were cheaper
The video store?. This guy thinks it's 1995
Berapa harga nya girnya boos terus pesen di mana
Good salesman.

You can still put a speed drive on the front if you remove the front derailleur.
Cheaper to buy a motorcycle or scooter...... and they can be hard for more than the last mile.
If there was a nuvinci hub that doesn’t need to be attached to the tire that could be mounted on tricycles that had a gear hub between the axle and pedals I’d definitely get this product and install it as my gear system for my adult pedal car, my 4 wheel ebike whatever you want to call it cause this would be awesome
Bike Friday should mention the preferred suitcase for each model of bike. They don't fit into just any suitcase.

Looks like it might not work very well for shorter riders with low seat posts
It's a scam it doesn't work !!!!!!!
how about if i ride this on bumpy road or thru the curbs ? they never mention
I know this was 5 years ago...but a map!? 😄
nuvinci was fine until i had a flat. hello nexus 8.
Total ripoff! with all the extras you have to buy makes this way to expensive for what it is and cannot use on electric bike.
Works great with my electric bike. Just use a milk crate and the bag that comes with it.
NuVinci hub will lighten up your ride, since it will empty out your wallet. That is much less weight to pedal around.
I have never been able to figure out all of the gears on a derailleur system, that's why I ride a fixed wheel bike, which is great, because I have never been able to figure out all of those brakes either.
Sadly, few and very very far between in UK.
Video store really what decade does he live in
The sepnine commuter trailer like that one is only$142.00 at Walmart and Amazon! not so greedy price!
plus, they do not seem to answer peoples youtube questions!
Greedy price of $300.00 for trailer with that money i could buy another Sondor ebike!

No maintenance my ass LOL

No sensor no battery. All mechanical. Lots of videos out there. Watch one, be enlightened.
How much you paid for patenting?
3 on the back and nine on the front.......this guy couldnt sell a heater to a eskimo.
even flying 90 miles down the road without coming home with a broken arm!?

how much does it cost/hub??
300-500
Brompton
Agreed for this price, and its rarity in UK a Brompton would be preferable. Excellent bikes the feller has though
Or take the bus
パンク修理の時後輪を外すのが面倒そうだ、長距離ツーリングに使うにはテンションプーリーをつけなければならない。 できればカセットフリーに付けられる無段変速システムが出来るとありがたい。
no brainer tech!!! Gotta love it...gotta have it! It's bananas that I hadn't thought of something like this until a couple of weeks ago! DONE!
So it's a product for idiots that forget to shift before a light and get confused from having 2 sets of gears?
Gara Von Hoiwkenzoiber Yes, for idiots.
CVT's in general have massive advantage over geared transmissions because they allow an engine to stay in the power band regardless of wheel speed. The Williams-Renault CVT-equipped F1 car was so set to dominate the league before it was banned in 1994.
I know there is a rack hitch mount, but will this clear my rack mounted on my seat post?

How does the range compare to an 11-36 10speed cassette?
Yifter the shifter
