it would throw a 503 speed sensor error if it was sensor related but not much else you can do bar take it to a dealer or try a different display. if a new display does not fix it then it could be the controller in the motor that has a fault.

lmfao and the retards keep buying it you dont even own your own microwave or anything connected to the internet these days it is a joke and ppl just dont see it until the **** hits the fan and the washing machine says no lol. i also bet bosch will me monitoring all the new bosch gen 4 motors...

using a batt that is smoking is utter madness but it is up to you but you need to open it up and find where it is coming from as all it takes is for 1 cell to go bad and take out the hole pack in the process. that smoke is not melting plastic and looks like a cell is venting electrolyte which...

that batt is dead the smoke is from the cells if it goes in to thermal runaway it will explode and burn your house down. do not charge it or use it on the bike as it is now a bomb

throw it out the window asap DO NOT CHARGE IT! AS COULD EXPLODE!

try changing the batts in the display first and see if that sorts it.

its not just bosch nearly every company is making it impossible to fix anything you own from phones to cars so only expensive dealer repairs are possible and no 3rd party parts would even work. if you think bosch is bad shimano go one step further and means if you open the motors they can tell...

i have a brand new cx motor from peter with the latest update and was using the purion display with no problems, i then got a kiox display and now ebike mode is back and shows needs a dealer update every time i power it on. bike works fine but fkn annoying and the shop wants £30 to push some...

i dont need the cable but my bike needs a dealer update for some reason £££, they have the software but dont have the right cable to plug it in! lmfao lol :rolleyes:

my bike with a dongle can do 35mph on the flat if i spin the cranks at 120rpm but is geared for this speed. if i want better climbing then i fit a smaller sprocket on the front so would go from 21t to 18t or run dual sprockets. tho you cant do this with the new motors but you can fit a...

under 15mph a motor can pull way more wattage than 250w more like 800w-1000w when climbing steep hills. my old bosch performance motor with 60nm of torque was good enough for everything i went up. tho if you want to change power settings ect then baffang is the only option as bosch shimano...

my bike had the bosch performance motor and i replaced it this year with a new cx motor and fitted a new kiox display so you can upgrade some bikes if the motor will fit but a gen 3-4 motor wont fit my frame. as for batts you can get a 3rd party 745w frame batt but there expensive and only work...
