Is what i cant stop thinking about when considering such vehicles..

If no speed sensor employed, the speedo will only provide valid data when the motor is running as it will calculate rpm and thus speed from the power applied.

look up in the manual the settings that relate to speed and wheel size and confirm they are correct according to the manual. is the throttle enabled for example? All the bikes bits are probably standard, however if bought from a seller attempting to comply with uk/eu regs ? could have the...

Not quite every requirement filled but... For the Yanks there is the aptera which (fingers crossed has promise, but will come at a price.. the UK/Ireland? solution?..

Probably a chat bot, what voltage motor 36v or 48v?? a quick google n browse tells me a 36v motor can draw upto 24a while a 48v controller could draw upto 18 a so if looking @36v motors your going to want a battery/bms that can deliver 25a or more ( greenlance site lists it as a bms spec...

When looking for a battery Greenlance.co.uk was recommended to me in here.. the numbers to look at are the controllers peak draw (Amps) and to ensure that the battery can deliver that volume of amps NOT TO BE CONFUSED WITH AmpHour(Ah or mah) rating which describes capacity not output. If in...

Google for 'ebike sensorless controller pinout' beyond the connections common to most ebikes, you may also have light power and a key control switch both of which may only have 2 wires .. even if present its not advisable to use a controller fed power source for lights as the internal...

Hi and Welcome , jammy git.. how come all my kit fails 1 week after the warranty expires.. who an i kidding i void all warranties with a screwdriver day 1. ;) Hope you choose to document your next build in here with lots of pics..

I was gonna suggest going for the 36v motor now and when/if you want to switch to 48v swap out the controller too, but a quick google to check prices suggests you could buy a hub motor for the cost of a mid drive controller! ouch!!

wont you need to spoof the controller somehow to not go low voltage? No experience myself with the bafang mid motors but are the controllers not internal and fixed voltage? giving you what 42-39v before low voltage cut off?

You could use the hall sensor solderpads for testing,? with the wheel static at least one will be grounded on the sensor pin to help identify the pinout. Is it just me or does that C2 position look like something blew in place there?? if so wont that point to something else at the root?

Does your display phone connection support remote control of the bike? If not hacking into the wire between buttons and display would be easy enough. A pressure switch or sensor attached to a tube for sucking/blowing might be an option for 'pressing up' or 'pressing down' and if a sensor -...
