    Charger won't start charging.

    The 52v charger upped it to 52.8v then I couldn't watch it anymore so unplugged it and off to bed. This morning I've done about 40km and its about 46.3v. The 48V charger still won't trigger, 52V charger is working. How do the trigger circuits in these chargers work? Must be a way to test it.

    Charger won't start charging.

    Not sure where to start troubleshooting this. 48v 20A battery, 27100 cells. It's done a lot of miles. About 4 months ago the charger stopped triggering when I plugged it in. It was hit n miss for a bit but eventually stuck on the ol' green light forever so I replaced the cheapest bit (the...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    Motor turned up yesterday from SCA Imports after 3 weeks. (which has to be record time for Aliexpress to Australia). The axle part inside the bearings is actually identical and the assembly fit perfectly into the freewheel casing. The threaded part of the axle is actually thicker on the cassette...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    Yep, I've realised there's no axle's available and it's a replacement of the entire inside assembly. After opening it up and checking the shell is ok I've ordered a new one. Mine is a freewheel version though which seems to be unavailable anywhere so I've ordered a cassette version and betting...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    Alas today we say goodbye to my awesome fattie. The chain side rear bolt came loose causing the wheel to escape the dropout. In it's attempt for freedom it snapped the axle on the other side. The dropouts are also worn and look "unsafe" enough for teh frame to be written off. This bike did...

    Full suspension fat frame for bbshd?

    subbing to this thread. I love my Reid Boss fatty with Bafang 1000w and and cloud9 seat but would like a full squish upgrade. That like above does indeed look a death trap though.

    1000 watt bafang mid drive giant anthem

    I presume thats a Shimano Press Fit BB. What adapter did you use to fit the BBSHD and what BB width is the BBSHD?

    KT Controller numbers and compatibility

    At a risk of coming to this thread late... I've just finished a build with the G062.1000.D motor (which is excellent btw) and paired it with this controller. https://www.aliexpress.com/item/32819334542.html?spm=a2g0o.9042311.0.0.3ccd4c4d8800Z5 40A is overkill but I run it configured for 20A...

    Chainline options

    Thanks Chalo, It's a freewheel so I can't really do much to it. Hence the ebikekit spacer solution linked. Also, perfect may be the enemy of good, but I still like good. I do agree a single chainwheel is better. I think this is one of those problems that needs me to stand and stare at the bike...

    Chainline options

    Let's use bullets! Bafang G.062 on fat bike Chainline easily 15mm too far left Can't dish to the right as rotor won't reach caliper Can't add spacer to rotor as cable exits axle and rotor would foul it. Need to move freewheel right. This would be ideal but they don't ship it to...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    Ok, new crank bolt on now so I can pedal. Did a good 20 km today leaving the battery at around 48.2v so plenty of juice. It's running a 36T 13T crankset which is nowhere near enough. Even on PAS2 it'll out pedal me at about 40kmh. I must say though the handling is really good. It still's...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    Still lots to do but this is a draft build to see how it handles, check the controller/motor operation etc. Pleased to say it handles very well. The G062.1000D motor is a little noisey but is drowned out by the tyre noise. Since I'm missing a crank bolt on one side I ran around for about 5k on...

    Bafang Hub to KT Controller phase/hall question

    Hi Folks, I have a new Bafang hub motor G062.1000.D connected to a KT Controller (40A sinewave). For now I've just colour matched the phase/hall wires. When taking off it's making a clunky/clicky noise and feels a bit rough which fades out once it gets up to speed and it feels reasonably smooth...

    KT Controller / LCD8H Headlight Control Question

    See pic. My light wires (orange/yellow) come straight off the incoming battery wires. No switch, no circuit board. Just raw 48V off the battery. I'm in two minds whether to keep it and make it nice as I'm replacing the whole rats nest with a 4in1 Julet loom, or be done with it as I don't like...

    KT Controller / LCD8H Headlight Control Question

    If you opened the controller up you'll see the 2-wire headlight circuit is soldered directly to the pads the battery 48v comes in on. So it's basically hardwired to the battery. Battery on, light on. The controller isn't logically in the circuit. I know this because at the weekend I opened up...

    Want to add rivnut, no space for drill.

    So about 6 weeks of research and 1 hours work. Like a wee skateboard. Rock solid. Job's a good`un. In the end there's 4 M5 bolts through the base into the plate. Nylon locknuts all round.

    Want to add rivnut, no space for drill.

    I have a plan! After much much searching and scheming I stumbled upon these "oil filter clamps" on ebay. I now have 3 of them and they fit perfectly with a suitable mechanical grunge look. To fit the battery I've went the Chalo route and fashioned myself an aluminium plate. To space the...

    Controller cables to one cable.

    So it looks like these harnesses do exist but are for Julet connectors only. KT Controllers have a big nonsense of JST connectors coming out of them. Since the number of cores needed line up ok I may get one of these and see how well I can fit it into my controller. Would be nice to open the...

    Controller cables to one cable.

    Hi Folks, In my current build I have a KT controller with the usual stramash of JST connectors coming out of it. I remember my very first ebike kit had a controller to single HIGO loom thing that broke out into display, brakes, gears etc once it got to the handlebars. This kept things all neat...

    Want to add rivnut, no space for drill.

    Thanks everyone. The battery is ordered so I'll wait until it shows up to see how to go about this. Aesthetics are important here as I'm going for a clean, alu metal look. So the usual highly effective but ragtag solutions (straps etc) aren't an option. It looks like either drill a couple of...

    Want to add rivnut, no space for drill.

    Hi Folks, For my latest build I want to use a DS-9 style battery (with 21700's) in it. This style needs bottle cage bolts quite high up in the triangle and in my frame only one of them would line up. I want to add two more but further up the triangle my standard power drill won't fit so I can...

    Re: Might Be A Dredd Lawmaster Build but probably not.

    So many months later I've got this project moving. The silly motorbike fork was dumped in place of a cheapie ebay $140 spring fork. Before ebiking I "done it up a bit" to check how it rides. The problem with the fork though is that it's longer than the rigid fork that was originally on it. The...

    Fixing a cheap battery cheaply.

    Hi folks, I have a cheap battery pack which has a busted connection on one of the serial packs. The positive fat connector has broken off of the little metal plate which I assume are welded onto the cells. Is it reasonable to solder this connection back on? Or does it really need something more...
