Update. Rode 15 miles yesterday and bike performed normally, no issues at all. So...the battery stabilization kit was the answer to the power shutting off. Just curious about cables and TCU. There is a cable from the motor to the TCU, and it seems the main battery connector cable also goes...

The battery stabilization kit has been installed. The tech said the kit includes some "brackets" that keep the battery from moving. The battery is held in with two bolts from the bottom of the downtube, so it seems odd that it could move. Maybe the battery housing flexes and sort of rotates...

I had a 2016 Turbo Levo Fattie, an early model. which was problematic, and was almost immediately replaced with a new one, by Specialized. Went through lots of repairs/replaced parts over the first two years, all under warranty, and then it settled down. Did have the occasional power shutoff...

Found a YouTube video on removing the battery from an SL bike. The right side crank and sprocket is removed to get to the motor mounting bolts, and the motor is dropped down, pivoting on the rear bolts, and is then out of the way. I see there are two cables going to the motor, one of which...

As previously stated the bike is in the shop for repair. They are backed up, and I have to wait a few days. The tech said my case of the power shutting off intermittently is a "text book case" of the battery shaking around and losing connection. This is why they will be installing a battery...

Just a month ago. Had the red line signal. A really stupid design, like they purposely made it almost impossible to change. From looking at various forums, it seems that battery is just for the display and is not in the control "circuit". Or am I wrong?

Sorry, but what is a DU or HMI. If you mean screen, my 2021 SL only has a "screen" (TCU) showing the battery charge level in blue/green "bars", plus the boost level "circle", not like the newer versions.

The bike is at the shop now. They said they have to remove the battery, which involves dropping the motor, and they'll be able to check the connections. Just thinking, I had the range extender battery in place. Even if the main battery connections were failing, the RE battery should have kept...

Last ride. Power suddenly turned off, but returned when pressing button. A little later, same thing, and at one point, happened every few minutes. Usually had to turn it back on myself, but sometimes came back on itself. Turned around at 9 miles, and later, maybe at 12 miles, returned to...

I recall early on that I had it inadvertently set it to draw from RE first. Happily riding along and the power suddenly went way down. Uh oh. Then looked at tuning screens, and switched that off. Immediately returned to normal performance.

My Levo SL carbon (2021) replaced my 2016 Levo. The early bike was heavier, but also had a larger battery capacity. Being an octogenarian, I need all the help I can get! to continue riding in my hilly area. I purchased the RE because of the lower battery capacity of the new bike, and the...

Saw this thread, and just wanted to send an update on my 2021Turbo Levo SL. I have been enjoying this successor to my 2016 Levo FSR. It's a great bike, much lighter, excellent handling, and though it has the lower power motor and battery range, it's been adequate. I added the RE battery to...

Stefan, I noted your comment about "it is a real mystery how your Levo is expected to operate". I have been concerned considering the age of my Levo, including Gen 1 electronics, that it suddenly shut off, and the fact that there is no explanation for the failure, and therefore no resolution...

The LBS expert is not aware of any "limp home mode" on my Levo. The only thing he can think of is the harness connection was suddenly lost. However, that does really explain what happened. I need to go for a few test rides to see if it happens again. I have never used Smart Control, but I...

Stefan, Just detailed the bike, cleaned up all the sprockets and chain, etc. Took it for a short ride. Runs very well in boost, and also smoothly with battery off in lower gears. When I first got the Levo, it was a disaster, and Specialized actually replaced the whole bike after one month, so...

Stefan, thanks again. I checked and the battery firmware is 4.17.1 and motor is 7.1.1. Also the odometer shows 2853 miles, which would be the present (third) motor, not the total for the bike or battery. This bike also had the harness replaced once, and the charger replaced once. It's also...

Stefan, thank you. I didn't think this old man, me that is, had any illusions, but clearly I do. I took off the chain, and the crank is free as a bird, no resistance at all. I knew about the Smart Control, but have it turned off. So if the "limp home" mode kicks in at 20% battery, is there a...

Have had motor issues, and my 2016 Turbo Levo is on its third motor, but has been great for 2000 miles. Yesterday, after 25 miles, it suddenly became harder to pedal, like a resistance to pedaling. The battery was down to 20%. This morning I turned it on to 100% boost and tried it. It was...

A new apparent failure on my 2016 Turbo Levo FSR. I'm on my third motor, which was installed in January, 2020 and has worked flawlessly. Have about 6000 miles on bike, so maybe 2000 miles on this motor. Rode today, and just at the end of a 25 mile ride, bike became hard to pedal, I...
