yeah, i am having a hard time getting this going, i found the ebay listing from when i bought it, but their pic of the controller clearly has the wrong pic for the controller diagram as it shows the throttle cable to be one wire for some reason. im about to say eff it, and just use one of my...

thanks for the input which controller do you have? mine is labeled: "brushless controller spec: dc42v-86v max 3000w max dc current 60a max phase current: 150a eabs some bar code junk 03/20/21 nsk lcd"

omg, thank you for trying to help, i just re-read my post and it was terrible, i was tired, aggravated and it was like 4am when i typed that out. im thinking more clearly now and will dig in on getting this going tonight.

tldr is the topic, below is other info about this problem transferred 3kw ebiking rear hub kit from one bike to the other and i cant get any throttle response, also no errors i dont know exactly how the brake switch works, but in my head, no brake wire connected could mean open ciruit...

yeah, ordered the cable from the uk. appreciate the help though i heard some things cant be setup using that usb bluetooth adapter, is that right? also, i see my controller doesnt have the tft display output, can i used that bluetooth adapter and a phone as a display for speed and heat info?

just got back to checking in. i have the qs205 4t v3. the bike is a custom ebike conversions using a 20 year old full suspension mountan bike. i got my 72150 controller for cheap, like $200 shipped, but it did not come with bluetooth, and i cant find a usb a to usb a cable, so i tried to make...

are all these models the same? are there clones? are there things to look out for? just to give a little back ground, i built my first ebike with a complete kit seller claimed the kit was 3kw, but i had it up to 4.2kw routinely. my second ebike is being put together one part at a time by me...

i am an idiot. the second rim was also a 32h, and my hub is 36h. so much for saving money and doing it my self lol just thought i would follow up. the good part of this is that these mistakes are costing me and i shall pay closer attention.

i am building a rear wheel with a 9c "3kw" rear hub motor. i tried to buy the exact rim twice, but it wasnt the exact rim, twice now, sun ringle mtx39 36 spoke, fine so i have extra rims now lol. i ordered custom custom spokes at about $100 for the spokes, they are 12g usa made spokes, they...

i bought it on ebay from ebikling. they claim it is a 4kw. the rear dropout requirement i think was 155mm.

yes it looks like that

i have six 22.2v 22ah lipo packs in a 18s2p config for 3kwh. i have three 1200 watt ac to dc 24v psu's and those power six isdt q8max lipo chargers. i can charge all six packs in about 20 to 30 minutes and still charge at might be about 1c to 1.5c. the problem i run into is that my psu's all...

i wonder how many of those inverters get destroyed when connected to too of voltage? i have been dragging around small and large inverters since the 90s, i mean in life not on my ebike. battery state of charge on an ebike is precious to me and i have 3kwh of lipo. i am thinking of building a...
