New High Torque IGH announced by 3x3

[ava1ar]

The hub shifts easily with no load, but under a slight load gets sticky so shift detection would be of benefit.

This is quite common for IGH - none of the hubs allows you to shift easily under the load. Electronic shifters potentially allows shift detection to be used (I think Rohloff/Bosch combo offers it - correct me here if I am wrong). Do you have any info about their electronic shifting implementation? Like supported motors, power source, multi-gear shift support?

 

[Deacon Blues]

My Kindernay will shift under load, but it doesn't like it. It was a bit of a learning curve, but I now pause my pedalling when I shift.

I have the 3x3 Nine on my Ebike,

Merlin, can you share us a coy of the owners manual pdf for the 3X3 Nine?

No owners manual is available that I can see. There is no maintenance, no oil changes, and VPL.Bike has all the necessary parts for a conversion. They will even do the wheel build at a cost. I have put it through the paces over 300 miles of riding, and it is operating superbly.

Brutal that I cannot buy this hub anywhere in europe and all the popular/modern IGH are essentially made in Europe.. Rohloff, 3X3, Kindernay... I can buy just the hub in USA from vpl.bike, but I contacted the german manufacturer of 3x3 NINE and they said that they cannot sell me just the hub, I need to buy a whole bike with this hub already implemented from their partners for a small price of 6-10k€. Hilarious. So I guess I will buy the hub from USA and pay the hefty import and duties costs, no matter that I live in the neighbouring country right beside Germany, lol.

I sympathize with you! (I reckon you are from the Czech Republic, aye?)
That's unfortunately the policy of companies operating on the Business-To-Business principle, and selling only a bigger quantity of their products to OEMs.
I wonder whether the 3x3 products would go to the aftermarket in a foreseeable future. Fancy a user has had his/her bike for, say, 7 years, and the IGH breaks. Would the original e-bike OEM still support the 3x3? Could the user buy that IGH in the aftermarket?

 

[hkckoo]

Czech Republic, yep. the manufacturer said that they plan on offering just the hubs in the future, but as of right now, they dont know when that will happen exactly. one of their german partners confirmed that they can order just the hubs from the manufacturer and they can essentially resell them to you, another said no bueno. I guess I will try to go this route to get my hands on the hub and do some riding during the summer.

What e-bike do you currently ride? I could see several posts of yours, and it looks you are very much interested in the belt drive and the IGH?

yeah, the thing is... i dont ride e-bikes i like to "ride manual" and challenging myself with unusual bikes and I also ride foldable bikes. i registered on this forum because there was a lot of interesting info when I was building one of my bikes, replacing the stock sturmey archer IGH with kindernay. now I plan to do the same using another bike model and another IGH, as kindernay went bust and the hub that I bought is leaking oil no matter what I tried. the bike that I am currently modifying with 3X3 NINE and hopefully even a belt, if chainstay length permits, to truly have an essentially zero maintenance fun bike to ride after work and as part of my workout, is halfbikes.com

btw: if anyone can tell me where I can buy the 3x3 160mm Brake Disc, as they seem to be making a proprietary rotor design, it would be much appreciated, I dont think I will be able to fit a 180mm that is available in some shops.

We are building a few samples with a 3x3 hub and a Bafang ultra motor.
Our prototypes will be ready by January 2025. I will update the forum with some pictures by then.

That is winning combo for sure, with a gates belt too, I am sure those in the market for a new Ebike in 2025 will be looking at this one.

I now have over 800 miles on the hub with no issues. 3rd and 6th gears are not totally silent like the rest, but that has always been the case. I find myself turning off the power as the gearing is so low in first that I can power up hills on my own. I only power up to stay with traffic. IMO the 3x3 is the only hub that survives the Bafang Ultra.

 

[Ebiker33]

Was watching the video, upside less maintenance and leaks, with just grease, downside if you ride in colder weather, but that isn't a issue for most.

 

[TPEHAK]

I have the 3x3 Nine on my Ebike, and I love it. The IGH shifts smooth, and at a stop. The 3x3 handles 250 nm of torque, and requires no maintenance. Add a Gates belt, and you have a drive train that finally handles the power of the Bafang Ultra. This is a game changer, and my dream bike has finally arrived.

What is the maximum speed you can achieve with this setup? The rear pulley looks quite large.

My Kindernay VII is over. Placed order on 3x3 with Vapor Propulsion Labs.

Where I can find the 32 spokes 12x148 mm through axle hub sizes to calculate the spokes length?

I am also quite skeptical about the grip shifter with wire actuation. My frame requires quite sharp turns of the cables and I feel it will cause excessive friction of the cable wires which may cause shifting issues. Unfortunately there is no hydraulic actuation option for this gear hub.

I'm using a Rohloff with my naturally aspirated 1000w Ultra and so far so good. 4000mi on one and 2500mi on another.
3x3 borrowed the dual shift cable setup from Rohloff and though I have some tight internal routing myself, it's been working well.
I ride for exercise and appreciate the tighter gear spacing of the Rohloff as many times +/-1 gear is all I need to change.
That said the 3x3 seems to be a tank and the Rohloff was developed before the age of ebikes so who knows how long it will last with this amount of power running through it.
Good luck... I'm interested in hearing how things turn out.

The 3x3 parts have arrived!

The parts look like very high quality product. The 3x3 hub has no free play between the case and the axles whatsoever (Kindernay gear hubs have some free play).

Unfortunately there is no chain tensioner in the kit and no tubes for the cables so this stuff should be figured out by the user.

The cog is asymmetrical which means you can not flip it to extend service life.

This thing feels heavy (and I hope they used that weight smart and put material where it needs to be to make it stronger). It is also quite large comparing with Kindernay, it looks more like motor hub rather than gear hub.

Will see if this can survive 3000W motor. According to this report 4500W busted this gear hub in 2 miles

Has anyone actually used a 3x3 Nine or Revolute IGH (with or without a mid-motor)?

I've gotten so sick of derailleurs I'm ready to pull the trigger on an IGH for my main BBSHD iron steed. The wise thing would be to try something cheap first like a Sturmey Archer or Alfine, but I know I won't like the gear range and in any case these don't really have enough torque-handling...

The rear brake caliper mount post interferes with the torque arm (on Dengfu e55 frame). I had similar issue with Kindernay VII and I ground off some material from the torque arm to make it fits. But the interference with 3x3 torque arm is bigger and would require removing too much material from the torque arm and probably also from the shifter housing. So I removed some material from the rear brake caliper post with Dremel

 

[TPEHAK]

The Problem Solvers Two-Pulley Chain Tensioner (remained from the Kindernay kit) does not fit because of the cog is too big (I purchased the smallest 3x3 cog with 24 teeth but it is still too big). I need to find a bigger chain tensioner or modify the one I have, or figure out the derailleur hanger extender
