Ah that makes sense!
Hi
After several months using this item, I'm thinking about other ways to unlimit because I have sometimes a ERROR 114 (or 144) and it STOPS my motor. Blinks two lines in red and blue and after five seconds aprox it starts again.
It always happens going up. mostly in rough slopes but also in soft hills. In Turbo, trail and Eco, with high and low cadence, always at low speed (between 4 and 9 km/h); what makes my think that the "brain" thinks that bikes is stopped and cuts help.
I've cleaned it several times, remonted and grease without any problem.
Some of the times it's been really dangerous...
Anyone with the same problem?
Any suggestion?
Ok changed back to the sram disc, still not happy with the gap, its slightly warped (bent), can i be sent a replacement? View attachment 19322
WOW, Fantastic work @jd_3d , I'm well impressed, and a little jealous!
its took me 3 days (off and on obviously) but I've finally read every post! I have just picked up my 2019 Levo HT today.
I noted a couple of posts re this bike. but the most recent on Mid June ws that it may fit with the universal mount?
Has anybody tried this and do you think it will work.
I have attached some pics below, including the specs of the bike.
I'm not that clued up with MTBs so any help you could offer will be amazing?

Question about mileage. Sorry if it's already been answered here.
I installed my lss with exactly 400 miles on bike. Now showing that I've done 120 more at 520.
Have I actually done 180 or 240 miles since install?
How much faster is it again? A fellow rider claims to be able to reach 40mph.
Thanks, this rider is claiming 3-1 on his product he bought. Same design as yours.It increases the assist speed by 1.5x. So around 30mph for usa. Plenty fast in my opinion.

Hi everyone, Hi JD! Sorry for chiming in here from nowhere, but that is exactly the topic / product I was looking for.
What a great ingenious idea / product you came up with! Fascinating!
Just got my brand new Levo 2019 last week and read through the whole thread - very interesting. Half way through I was eager to order one set of your LSS and did so with your provided link, only to find out a couple of pages later, that there is already a V2.0 available. So why do you still offer the original design, when there is a better version now?
Also if I would have known that the smal gear only lasts about 500km I would have ordered a spare immeditatley, because the shipping cost for these plastic parts are quite hefty and will double the gear price for me. Aynways, too late, but looking forward know the reason why V1 is still available.
Many thanks in advance!

Hi , posted another at end , but I just got 2020 and added lss . Same issue first time I tried to climb in the dirt . Low speed issue. Removed lss and all good .?!Hi

Hello , just got a 2020 levo and had and had already purchase the LSS for 2019 , but want the 2020 to get a large. To answer the question will it work the answer is yes but had to use some O-rings as the cover does not stay put because of the change to the spacer for 2020 ( wonder if this was intentional ha ha )
After install did about 100 Street miles with no problems ,
Although yesterday after my first trail ride on this thing I started to encounter the same problems as someone just mentioned , Low speed climbing engine cuts out and flashes with the red and blue lights . Discontinued for a while tried a few different things to no avail . Luckily I had the old parts with me and pulled off the LSS and no further problems on the ride , and yes I did more slow steep climbs .
Any thoughts ? I do hear there’s a problem with the power cords and some of the 19s but figured this should’ve been fixed for 2020?
Inquiry coincidence that as soon as I took off the LSS I had no more problems
Thanks @Justride for the info. I actually tried to duplicate this phenomenon by riding slowly in the lowest gear but was unable to. Maybe I need to find a steeper hill and try again, but I'm wondering if Specialized has perhaps updated their firmware and added additional checks? Like maybe they now have something in there that will error out if it thinks you are riding too slow? I'm not sure how else the LSS would cause it to throw an error only in slow speed uphill climbing.
Finally I took it off and no more problems.
For sure the reason is the speed, as seeing the bike speed in the GPS it was 0.0 when it was stoping assitance. Maybe too much "radial length" in each LSS return compare to original. Is it double?
It would be great to have another version with less desmultiplication. If you consider it, I can help you. I have a lot of experience in mechanical design and 3D printing, but will be stupid to start from zero.
Do you agree?
I didn't update firmware since I bought TL at Nov2018.Thanks @JAMh for the additional info. What I find strange is there are over 50 people with the LSS and we've been using it for 10 months and no one has had this issue (at least that I'm aware of), but suddenly 2 people have the exact same issue, so I'm wondering if Specialized changed something in the Firmware. Do you know if your bike is running a newer version of the firmware, or when was your bike last in the shop? The other bike that had the issue was a 2020 model, so it is certainly using the latest firmware.
Regarding the LSS, it slows down the rotation of the magnet by a factor of only 1.5x, so it is already quite minimal. It gives a 50% speed increase currently. I'm not sure if people would want it if it only gave them 25% speed increase?
Another factor is the space is very small to fit the LSS so its difficult to significantly change the planet and ring gear radii without increasing the size of the LSS, but if you have some ideas please PM me. There's a good planetary ratio calculator here.
Jamh,I didn't update firmware since I bought TL at Nov2018.
I only update the App, but for me it started almost when I bough it. Talked about it some private groups and some friends told me they have the same problem but they solve it increasing cadence. I can solve it going up faster, but sometimes it is not possible.
Anyway, LSS is a very nice idea, but I need a special version. Will talk by PM.
Thanks
2020 levo , ( difference in spacer?) and you can see my magnet , couldn’t be issue ?

I got your system at the first of the year. I have a Carbon Comp Turbo with the system mounted on it. I had to make an inner ring to support the inner gear but all of it works just fine with one exception. I do not get a speed increase and am still limited to 16MPH. Everything rotates freely, I have the right magnet and everything looks good but it just doesn't change anything.
Thanks for the reply.Hi @Quiui, for the LSS to work properly the center gear (sun gear) needs to stay stationary relative to the wheel that rotates. So it sounds like in your setup the sun gear may be loose, which is allowing it to spin. In this situation there would be no speed increase. So, check to make sure the sun gear is tight on the axle so that it doesn't rotate.
Also, it looks like you are in the USA, correct? US based bikes should have a speed limit of 20MPH when stock, so I'm not sure why yours is cutting out at 16MPH. Do you know why that is? Do you have a Europe spec bike?
