Hi all new to this. Forum not sure exactly how it works but here goes , I bought a new. Turbo evo gen 4 sworks in may it was unfortunately a lemon I then bought a turbo I Levo gen 4 comp and it was fantastic after we got all the initial bugs sorted but , a month ago there was a power drop as I was pedalling in turbo . All. Of a sudden no power , felt like motor had died , then it caught again so it did this a few times on the way back to the trail head . Took it back to my LBS they got hold of Specialized and the motor was swopped out. Now 2 weeks ago I got My new sworks and I love it butttt
trues bob I was riding in a race and bam power drop again twice in turbo , I then powered down into trail rode conservatively with the cadence (still won the race ) but there’s something defiantly up with the motors and power loss . Took it to my lbs , there got told by Specialized they need to take out the wiring harness and replace it with one that does not run the derailed as well ,so I’m on. SRAM battery now for derailer. Funny thing if u do this there’s actually a visible speed differance in gears been changed with the big Specialized battery and. The SRAMs battery IT ACTUALLY WORKS BETTER WITH THE SMALL BATTERY (that’s a serious issue no?) so the thinking is the cpu is getting confused with where to send power and the motor is taking the knock , its a temporary fix , I WAS SURE TO ENSURE THAT cause one of the buying points is that the battery runs everything and runs it well! Well not so well apparently , I’m the second chap this week that got a new wiring harness at that one store.So. Here’s. My question has anyone else had these issues and is SPECIALIZED International also doing a quick fix bypass instead of rewriting the software Or getting the correct harness in place or fixing the problem properly. I’m in South Africa just for infos sake . This seems to be a problem across the motor range so the 3.1 Specialized 101 nm motor and the SWORKS 111 Nm motor

Hi, did you solve your problem?
I'm asking because I feel the same way.
 
Back in June I tested the Levo in a Demo Ride, and I experienced exactly the same issue. For this reason, I’m quoting below the relevant excerpt from my review at the time, where I described the problem in detail.

"During the climb I notice an excellent pedaling position, and a shock that, once settled into its dynamic sag, provides great support—ideal for such steep ascents. But as the minutes go by, I start to notice a slight hardening of the pedaling in certain situations… Could it be some sort of “traction control,” described by the designers as one of the improvements of this motor? In truth, it bothers me a bit: we’re talking about the blink of an eye in which the motor seems to hesitate, generally in correspondence with the hardest impacts.
I continue the climb at a more relaxed pace. The gradient becomes less steep but at times more technical, with limited grip. I continue to appreciate the steering precision, even though the 27.5" tire clearly offers less traction on loose rocks, mud, and slippery surfaces compared to the 29" I’m used to. Not a huge difference, but still enough to make the difference between clearing an obstacle or stopping when you’re at the limit of your riding skills and available grip.

Meanwhile, strange messages appear on the Garmin connected to the Levo: “eBike battery low,” even though the battery is now at 65%… and after a few seconds a message on a red background also appears on the Levo display: “check battery connection,” or something similar. After that, the bike starts missing beats, as if it had fuel starvation issues, and then it shuts down. I try to turn it back on and everything restarts as if nothing had happened. This annoying behavior follows me throughout the entire morning. And even after tightening and loosening the battery several times—a very quick and easy operation—and checking that the contacts were clean and dry, it reappeared at every bump, preventing me from tackling the subsequent technical climbs with confidence and from forming a more precise opinion in these situations.

20 seconds in Turbo, 2 seconds off, 15 seconds in Turbo, 1 second off, and so on… Obviously forcing me to get off the bike and push when this happened on technical sections. "
 
Sounds like the typical battery/nest connection problem and wire pinch in the hot shoe cable.
There are other threads on this but intermittent power surges is probably the battery nest. They have a new nest but people still having problems so do your best to reseat it carfeully and add dielectric grease to the terminals. Start a warranty claim on the wiring harness and hotshoe cable.

I still have issues with my Gen 3 turbo Levo in Turbo mode only. I’ve taken it in to where I purchased it twice and they can’t fix it. A new motor is the only option, so I decided to just use the bike without the turbo mode. No problem at all in the eco and trail modes. I was told the motor doesn’t like low cadence in turbo mode and was not designed for that type of riding. I have about 2500 miles on it, and it started around 1000 miles. I’ve adjusted the power and torque parameters in the software for lower power assist levels and it helped a little.

Ya really hope they sort a solution asap because it’s a super awesome bike to ride for joe the battery solution is working but you kinda want the thing to work correct

is it easy enough to add the hotshot again? or do you need to take it back to the shop? One specialised have sorted the issue out...


I find it funny that a bike company that has been making bikes for over 20 years can’t get soothing like this right ... then a Drone company comes in and gets it right the first time.....

If I run a range extender the SRAM t type mech stops working around 4 times per battery depletion, also the motor lost drive today sounds like the teeth or sprag clutch has gone, s works levo gen 4 bought last July,
