In this same forum there is a thread already about BOSCH 504 error, Speedbox 2.0 and Speedbox 3.0 experiences. A bit of sweetness and unfortunately a bit of bitter... Bosch Error 504 With Speedbox 2 - EMTB Forums

I'm wondering what is the mileage of kouettte's bike as well as his/her riding style. He/She claimed to do 160km/week, so either it's working as expected, or he threw the bike away :). @quick_nick assuming you always respected the wait times after an unlocked ride, did you contact SpeedBox...

Wow, thanks for sharing this with the rest of us. I recently mounted a v3 kit and so far I only did 50km without a problem. I already had 2 strikes with a BadassBox in the past, so I'd hit the 3rd this time if the same happens to me. Did @DJ_Sixty or @kouettte have seen this behaviour that our...

Thanks Mark for the answer. I'll try further this week to see if the error clears out. I can't really change the bike, given that the bike was purposedly bought to be able to fit two child seats in the back during the commute to school. The worse of this issue is the on-purpose misinformation...

Hello everybody, I'm new in the forum. I have a similar issue. Does anybody have an update to share about this issue? @Marc_250 maybe? I have a Brand new Riese Muller Multicharger GT with Rohloff E14 shifting and around 62 "fake" (~100 miles) the 504 error appeared. In my case I'm using a...
