I created a purely mechanical Turbo Levo speed limit increase

Yeah will fit if you stated the right hubs . The new models are better as no need to have a gap between the outer case and the disc , just push on til it rests on the brake disc . Great product that is faultless 👌
Edit I’m assuming you got the planet3 model ?
I received the parts and installed them a couple of days ago. Everything it works, on Kenevo Expert 2023 !!! So nice being able to hit 40kph :D


1. What is the maintenance for the gears? Spaying some wd-40 on them, grease, regular cleaning etc?
2. When I fully press the outer plastic cover it rubs on the plastic parts that are mounted to the disc. Is this normal? I ended up by pulling the outer part 1-2 mm but now dirt can easily enter.

Thanks,
Stefan

I take mine off maybe once every 6 months to check and clean but no need for lube 👍
 
Hi, I'm interested in trying this out. I have a brand spanking new 2024 Turbo Levo Comp Alloy.
Some help would be appreciated though. Which version should I buy? What's a suitable supplier of correct strength of magnets and other parts needed?
Also, fitting on a 24 model, I presume it's more or less identical with the 23?

Thanks
 
I’ve had 2 from this company which have been faultless and Alex always responded to my questions. Pretty sure the 23/24 is the same and the website asks what wheels you run so easy . I’ve used both 2 and 1 magnet but settled for 1 cos less things to go wrong !


 
Planet 3 is on sale at the time is this because it's a new version around the corner?

It should not be pushed fully on the cover… there is a spacer thing that you need to use to get the perfect gap between the two or you will be wearing the system down excessively

Yeah my mistake, with the planet3 type pushing all the way only applies with a hope hub !
 
@jd_3d I had this on my Levo and loved it. I still use the stock SRAM rotor but upgraded to I9 (Industry 9) Hydra hubs. Are you able to make a sun gear for that hub?
 
So this method of derestriction is basically not possible to be seen by the dealer for warranty right ?
I'm worried that it's easily spotted when police make a simple check of my ebike
 
На моем BH с мотором Brose я поместил магнит на концевой оси педали с задней стороны шатуна, открутил датчик датчика с внутренней стороны цепи и прикрепил его стяжкой-молнией к внешней стороне цепи. Теперь он использует вращение педали, а не колеса, и я могу крутить педали со скоростью более 30 миль в час/50 км/ч. 1 доллар за магнит.......Магнит, который я использовал, имеет размеры 12 мм х 4 мм и находится примерно в 20 мм от датчика.

я также сделал на своем турбо-левом и он реально поехал! Но через полчаса езды выключился мотор в аварию и отключился, на рамке загорелось красненькое. Я его выключил и снова включил и опять поехало всё соскость неизвестной. На следующий день произошла такая же история - мотор отключился и я его снова включил и уже он больше не отключился. Интересно, что будет дальше? Русский стиль. Я хотел заказать такую же планетарную шестеренку, но пока так поезжу.

EDIT 2/21/2019 - Hey it's me JD from the future (2 months after this first post). I wanted to add a little info here on how you can obtain your own set of gears that is 3d printed by Shapeways so I created a quick Wordpress site with some info:

Guide to the LSS

In there is information about the latest design, links to purchasing, and installation instructions (or if you just want direct links, here is the LSS and LSSDT). Anyway, I still encourage you to read this entire thread as it provides a ton of information on the development, prototype feedback and reviews of the kit. Enjoy.
-----------------------------------

I've only had my 2019 Turbo Levo a few weeks but already felt the need for speed. I do a decent amount of road riding with my bike (at $7k, it's my do-it-all bike) and felt the 20 mph speed limit was a little too limiting. However, I don't want to mess with firmware changes that could brick my bike or cause warranty issues. I also had a number of requirements:

1) Must be 100% mechanical (no software changes)
2) Must be easily reversible (less than 5 min)
3) Must not have any re-wiring of the bike/sensors
4) Keep speed limit at around 28 mph.

In California Class 3 electric bikes w/ 28 mph speed limiters are legal on the roads, so If I made such a device I would be reasonably within the law when riding on the road. When riding on trails I do not need more than 20mph.

My wife thought I was crazy as I sat staring at my bike for like 30 minutes at a time lost in concentration for thinking about the best way to do it. Fortunately I'm good with CAD and have several 3d printers so once the inspiration for a planetary gear set came to mind, I was off designing...

A few days later (and several failed iterations) I had prototype 3 installed on the bike (ignore the ugly blue color, it will be stealth black eventually):

View attachment 8975

Little did I know at this point it would take 13 more prototypes before I got it working to my satisfaction. Since this post is getting sort of long I'll stop here and call it Part I. If you guys are interested I can do more posts and continue the detailed information on the design/troubleshooting and final outcome (spoiler: it's awesome).

Obligatory info:
Please read about the electric bike laws in your country: Electric bicycle laws - Wikipedia
Now that ShapeWays is not offering this do you have any other options for purchasing this part? I’m looking for the LSS.

Thanks in advance, -Andrew

Yes, another option to purchase please!

Also I am willing to pay for the 3d models to print them myself if that's an option.
 
Why not simply get a PLANET3? It's double the ratio of a LSS and seems to be updated and worked on all the time. Not sure you can print anything yourself but if you're just looking for a solution it might be it.
 
Fair enough. Since the OP disappeared and other people were still interested in this approach, I thought I'd give them something to consider. I ordered one that should be here in a few days. Hopefully, it does what it says it will.
Please let us know how it goes (installation, top speed, etc).

Thanks
 
Any reason why it does not work on the gen3 ? Works Fien on my gen 2, but on the gen3 the bike gives me a error that it can't read the magnet ... I think the sensor is in a different positions.

It could be that there is a detected difference outside of "normal" parameters between speed and cadence and it throws an error.

On Gen3 the speed sensor is in a hole located in the dropout area of the braking side of the rear triangle, so it's "obstructed" by the part of the frame between the sensor and the magnet - compared to the Gen2 where it sat in an sensor carrier that had a partial cutout on the side facing the magnet so there was no obstruction. This is the reason why I had to modify the planets and magnets for the Gen3 Levo and Gen2 Levo SL/Kenevo SL, to basically make them stronger and have them more reliably trigger the sensor.

@RZRCrawlin Your purchase from eBay might not be what you expected considering they're using a photo of a Gen2 Levo to promote a Gen4 product that will not work on Gen4 without costing you the first 3 gears on your cassette. You can read more about the limitation of the new Specialized firmware on Gen4 bikes with mechanical derestrictors here: PLANET3 on Gen4 Levo.

I have a Gen 3, but I'm kind of expecting it to not work for one reason or another. I like to fiddle. Sometimes it works and sometimes it doesn't.

Then it's more likely to be OK. However, note the conical head screws that will tighten onto plastic. Plastic will go into creep over time and the screws will loosen, you have to use threadlocker but even then it won't really work long-term because there's no proper preload on the bolt. I'd much prefer when people copy my invention to copy the critical aspect of properly securing the screws, too. :)

I got it and installed it. Used thread locker (thanks for the reminder and suggestion) and white lithium grease. Just took it for a quick spin around the neighborhood. It works. But I'm going to need to adjust my settings. I'm going to need to make the settings even more regressive in the app or change how I have the battery work. Unlike most battery bike guys I know, I don't run turbo. I use Trail and I have that set at 50/100, which "can" get me to turbo, but it isn't the default setting. I don't get enough of a workout if I do. So, I'll have to figure out how to set up setup the tune to give me similar motor output but let the gadget get me to 30 mph/50 kph. I don't necessarily trust the printed plastic nature of the gadget, so I'm taking the parts to put it back to stock, if needed. We'll see what happens.

I went for about 14 miles this morning. About 2,000 ft of elevation climb. The LevoX gadget worked just as it was supposed to. No unexpected issues.

The downside is now instead of letting my Specialized app talk with Strava, I need to use my Garmin 840. Turned off the bike connectivity and put on my old Garmin speed and cadence sensors. Once configured, everything works as desired. Speed, cadence, and distance are now accurate.

FWIW, I'm running a "set it and forget it" setting with Trail set at 50/100, Shuttle at 0, and Responsiveness at 40. It works well for me. I'm just needing to adjust how I setup for aggressive corners a little differently now that I have more speed on tap.

I did put a decent amount of lithium grease in the gadget, but I'll keep an eye on it after washes.

I'm pleased so far!

Thanks for responding about the install and progress.
As for the Levo's programming: Take full advantage of all three selections you have. Program "Eco" for one setting, "Trail" and "Turbo" for others. For example, one setting could be for when you want extra power to go greater than 20 MPH.

I have them all programmed. I just tend to use the Trail program fairly exclusively.
 
I don't know if lithium grease is a good idea. If the base of the grease and the plastic compound don't play well with each other, the grease might swell and disintegrate the plastic over time. Since both the PLANET3 and any copycat device basically run on the same principle i.e. it doesn't transmit any torque or power - it just rotates the magnet slower than 1:1 ratio and the involved parts are very light and the kinetic energies involved are next to nothing, so long as you don't squeeze the parts together and cause undue friction - it should work indefinitely without any lubrication.

Unwanted side effects of grease can also be that in the device you'll find brake dust and any other dust/sand particles which will form a friction paste and wear stuff out over time.

My recommendation for PLANET3 is to only use silicone spray and wipe everything dry after spraying it - and this is only for people using it in the north of Europe (Scandinavia) or similar regions in the US, in snowy and icy conditions. What's happened before is that moisture gets into the device (snow melts) and then once it freezes again the device is frozen solid and the plastic splines can rip apart on next rotation of the wheel. Silicone spray is hygroscopic and repels moisture thus preventing this. Once spring/summer rolls around, a spray of some isopropyl alcohol and another wipe dry will ensure it doesn't attract dust and crap during warmer months.

I appreciate the recommendation. I'll can pop it off, clean it up and use silicone spray. I'm in the desert. I probably don't need much.
