Finally got te bike back together after it running successfully on a bench Recently had a new battery bms Hall sensors replaced in motor Hub motor is a bmc battery is a 52v pack from em3ev with 30q cells It worked fines for the first 100 feet then as soon as you hold it at full throttle its...

Sounds like exactly what I want from mine ! So you can peddle with the ' power assist ' set to say 5a for example ,then can I use the throttle to get my full power the controller is set to ? Also can you change how much power is put out from using the tourque sensor while out riding ? or is it...

Hi I'm trying to work out what the best set up.for my bike is its bmc hub motor 3077 12 fet controller from em3ev Throttle 3 speed switch and cruise control I want to have pedas assist aswell as throttle I would like the power to come in sort of proportional to the tourque I put in to the...

Hi I've been looking at ebikes on alibaba .I want a bafang g510/m600 motor .Im undecided on weather to take on building my own battery using quality cells Ideally I'd like to purchase just the frame and motor and build using my own components Can anyone reccomend a frame I like the geometry...

Blob of solder stuck In a gear it was All good now :)

Hall sensors fixed motor runs but it seems to be a knock coming from it when spinning sounds like a bearing has gone ? Anyone know if this happens often it hasn't done a lot of miles

That's interesting I've just changed the hall sensors in the motor hope it works It was running fine before with a 'infineon' 9fet controller from em3ev

I'm looking for a 9pin connector for phase hall wires that can carry 20a Any recommendations? I'd like to be able to mount one half of the connector like a socket on a enclosure where the cabling exits the axle of the hub motor Ithe connecter can be 20mm in diameter max

Thanks 👍👍👍

Hi can anyone confirm that this is the hall sensor used in bmc hub motor the ss40 Thanks

Can you help with a link to replacment hall sensors or the type that's used Also what are the 2 resistors for all the pics I have seen have 1..this is a bmc motor but I was told there the same as macs Cheers

Yes I have 5v coming out of the controller not connected So have I got this right the red positive is there to power the hall sensor. once the sensor operates its let the 5v through and back on the neg? And I guess the controller detects this through resistances or some other magic lol I've got...
