connecting to the motor will be the 3x phase wires which are the output from the controller. it appears your controller is embedded with the battery cells?? with only 3x phase connections to the motor its not employing motor sensors unless there is an additional thinner wire connection too...

Way to go - lets invite F-witt farage and his party of reform cockroaches to the 'ebike party' Not as if they are known for any monumental screw ups recently is it.. They are sure to fix things and make it all better..

Phew, Seems ive been following the correct protocol for 2 yrs in ignorance, or perhaps i read the instructions? - Naaa.

?? Afaik? The optimum rpm of a motor IS directly related to the voltage level of its power supply. Hence the 'bonus features' of overvolting or running a motor supplied with a 36v battery pack and controller with a 48v Pack and suitable control system to achieve 33% increase in both achievable...

I have had a few bikes stolen, one from my back yard, and never anything more special than last years mid range seller left in stock and priced to move. Then again as a kid i would walk the dog where lots of bikes stolen in the city on a friday/saturday night would get dumped and many after 6...

saw this and thought it was fitting here..

Meanwhile in Oxford city centre i was buzzed past by at least 6x no-no ebikes with dinnerplate motors or steel box section frames and fat tyres, and speeds well in excess of 15 mph.. not a group just on the 25 minute run into town. No one being a dick in particular, just taking advantage of...

Be ultra sceptical when purchasing battery packs, they are high value easy to fake/fill with sand packages, at risk at numerous points in the supply and manufacture/fabrication chain. The 'premium' price charged by local importers who assume all the risks is worth every penny imho, of course...

If you get stopped you will loose the bike and BATTERY! Imho Your best bet is to pull the motor check the dates and pray your within the return window. While up until recently police stop/checks have been rare, but it appears there is a growing trend for demonstration of police doing...

I agree the lad is a victim possibly of a faulty brake sensor perhaps just of ignorance, but the vid came to my attention discussing the DYU style bikes elsewhere and was shared as evidence of them not being the safest bikes available. I cant agree with your deeper assessment of theoretical...

Do all other inputs to the system such as throttle, brake sensors etc have their own dedicated sockets to plug into or perhaps are they expected to share the same 12 pin plug input as the display using the otherwise unpopulated pins?? the picture in the ad linked to certainly does not employ 12x...

Can you get your pushbike back? - no easy way to say this - Mid to top of the range ebikes tend to come with closed proprietary control systems and limited access to spares and information through authorised dealers etc. If you cant source a replacement display from kalkhoff even if you match...

Yes a standard motor 9 pin connector, Be mindful the pins are delicate, 1x already looks a bit bent, tho cld just be a pic artefact? perhaps a big blob of blutack to protect em till the new kit arrives.. re testing with 20v batteries, no- just dont, for one while ads will headline 24/36/48v...

Might be better to start a thread of your own detailing your problem. Chaps like @saneagle with a deep breadth of ebike know how will probably overlook this as a fixed issue.. The controller you pictured probably wouldnt be suitable for the SAME fix as above as its got hall sensor connectors...

What do you mean by surge? what test did you perform to reach this conclusion? If you mean when reading battery voltage between ground and one of the display pins it starts to fall while reading? or perhaps something else? Im not familiar with your bike.. so this might not be possible, but...

circa 90% of my understanding probably stems from a few utube vids i watched a couple of years back during lockdown where a few diy attempts at a build of such tech was attempted powered by an array of batteries only a utubers budget can afford. i think the US Channel tech ingredients? might...

Watch this..

Without a backup google to check if emp related even if targeted (viable tech since the 80's at least) its sensitive electronics ie the controller/display/bms that are all at risk Im unsure if the hall sensors in the motor would be effected? but am pretty sure both magnets and coils are robust...

TV detector vans again methinks.. any 'emp ray backpacks' that appear will just be cosplay.

fwiw i was reading Orange Black brown/gold, 3, 0, x10, 5% 300ohm 5% Bt now band #1 looks gold too ???
