    Still throttle wiring problems

    OK since I couldn't figure out the 6 wire throttle I bought a 4wire throttle ( 3 + yellow power wire for LED) . Is the yellow for throttle high voltage or low? I see by some videos it says to connect straight to battery but I can't figure out how to do that unless i connect the throttle yellow...

    Bench Testing controller with psu

    Since I am having to mix and match items that are not in "kit" I'd like to simplistically test the controller without my full fledged battery. I've already fried the connectors of 1 controller twice. Scarey. I'd like to use a minor power source so a psu power source (‌maybe at 12 volt) to see...

    Voilamart front hub motor normal?

    After someone mentioning the voilamart motor kit I bought one. I assumed this poster was speaking from experience but now I regret buying it. what a waste of money on more than one consideration. Maybe it's just my legs but I've ridden for many years a 9c DD front motor with no problem in...

    Wiring an on off switch into unmarked Chinese controllers

    OK so since my old motor bit the dust I bought the cheap kit from voila ( amazon). It was a 500 watt motor and I have no instruction sheet. I can identify the sensor wires, the power and the phase wires. I think I can identify the sole 3 wired throttle connector and the rest is Greek to me...

    Scammers hit this site?

    I wanted to get feedback on whether faceless/anonymous scamemrs have scammed anyone else here. These would be "members" that are or cannot any longer be identified as members. I was contacted through a third party about someone allegedly having those 9C side plates I wanted but my gut is...

    9CJ210061615023 9C FH motor

    I bought this motor from a now defunct company and the 9c company doesn't seem to have any drawing or specs on this. Might anyone have the specs and diagrams o this motor? I want to change out the axle and bearings and need sizes or parts numbers. Thanks in advance.

    Mold in the 9C hub motor

    It's been some years since I got into this motor. I was going to upgrade the phase wires ( running hot and melting) wire and so disassembled it. WhenI I saw the inside of the magetics all covered in black mold and 1/2 of the stator covered in the same mold. It was not on the side where the wires...

    Burning phase wire contacts that breakdown

    It happens occasionally but I never know when. I run a 42 volt battery on a 9C motor. The motor wire look to be about 14 gauge...and I currently switched from bullets ( which also burned and eventually melted) to a spade type that allegedly was rated for higher temps. How is it people using...

    Battery charger errant?

    After making my first battery pack I get my first ride in and have a 36 volta battery that reads 33.8v left. I plug it in to charge for the first time and my charger tells me it's full charged ( green light) The charger was from another old Ezee battery that also was 36 volts. I do have a...

    vruzend battery wires & connections?

    I am assembling the vruzend battery system. It will have the bms and I need to know the wiring from BMS to incorporate a blade fuse and on off switch. The charging port I assume is connected separately and that already has it's own blade fuse so I should be good there. Any diagrams for me...

    BMSless limn battery and hobby charger

    Using the original battery cells from EZee the cells seem to be LIMN. Since trouble when the battery kept shutting down for unknown reason I am trying using my battery BMSless. I tried for the first time to use a hobby charger ( Reaktor 1000w 30A) and a psu as power source. The psu is putting...

    Series wired battery gone wrong?

    Hey all. I have rewired my old Ezee battery ( one cell went "bad") I'm going to repack it in an old camera bag and remove the bms. I am assembling it together and thought all was well with the world...BUT... one pack measured 18.17 V and the other measured 20.24 volts. For series wiring that...

    Ezee battery fix

    My 36 volt Ezee battery has it's first incident of cell failure. After having my throttle instantly stop every time I tried to engage I finally pulled apart my battery to explore BMS and cell voltage. Most of them ( 10 total) measure good 4.07, 4.09) one cell measure only about 2.38. I'll take...

    Tire Abberation

    I was changing a flat tire when my new tube also developed a flat. Upon inspection I noticed this unusual part that looks banded and to one side is where it sprang the leak. Is this structural abberation normal? BTW apparentl Kendra is the same as sunlite according to the markings in this...

    Are suntour forks total crap??

    After wrecking my surly fork due to spinout I am on the hunt again. What I am gravitating towards is the type of steel forks with dropouts that are beefier resembling those used on bmx forks. Some of these have extra holes where a custom made plate torque arm could be made similarly to the vast...

    Newer KU123 controller

    I got 2 new ku123 which has been redesigned with a different board. I run sensorless and despite all the combos I have tried with the phase wires I am still getting stuttering. Wire connections seem tight. I was wondering since they have included a couple of new features if something on the...

    Guide for controller troubleshooting

    As a newbie to controller repairs I decided I should not waste the 4 broken ones I have and learn to fix them as well as beef up any new ones. I have recently tested a ku123 controller I have ( after putting in new mofsets 4110s ) , took out wires I didn't need and tested the continuity as...

    Lyen EC-12411OSL won't work with Ezee motor

    I bought a lyen controller a couple of years ago and never got it to work...I'm trying again but am having no luck with the Ezee motor. It is sensorless and I found the three variations of phase combos that do run but shortly after throttle application it shudders or stalls. It didn't do that...

    Controller burned or on its way?

    My bike conked out again yesterday and my I decided to take a look at the controller thinking something may have burned or I need to beef up the shunt. I saw some dark discoloration which looks like a burned mofset perhaps. If one mofset burns out will this kill the controller or can...

    EZee went sensorless but won't start on wheel

    OK since I couldn't figure out how to get to the hall sensors..I cut out those wires and tried to run my ezee with a sensorless controller. With the wheel apart I had no problem.. tested the controller and newly wired motor and it went run. Screw it back together and out it on the bike and it...

    eZee stator removal

    Has anyone figures out how to remove the stator from rotor? I need to change some sensors and can't figure out how to remove this sucker. I am assuming the bearing doesn't get removed as a see no screws or on the other side is the cog mechanism and likewise has nothing to indicate removal. There...

    Heated phase wire on Currie

    I have one of those nifty Currie motors. Have have been having an ongoing problem one of the three wires seems to heat up considerably ...to the point of melting the Anderson housings. I was cursing the Anderson connectors as they were always coming "loose" and cutting out on me. After again...

    Jerky / power with no throttle

    I had a problem start yesterday. aside from on off power performance ( which I attribute to a likely unsolid connection on one phase wire. Hopefully I have that fixed but I had a jerkiness when the wheel moved as I was at a stop sign and I wasn't even depressing the thumb throttle. I tried it...
