    Throttle response/lag problems

    Sort of, I don't get torque when I want it during turns. On my gas machines the torque kicks in much much much faster than the electric setup, so I can modulate the throttle and change where the weight is on the bike. No such thing on the ebike. I'm kind of interested in reprogramming the chip...

    Throttle response/lag problems

    That perfectly explains it. There's always a lag, and it changes depending on speed. Perhaps the ramp speed can be changed; A diode or a resistor, etc? It's more than likely baked/flashed into an IC though.

    Throttle response/lag problems

    Yup, batteries are LiPo. Max output is 17kW so that's not a problem. I did beef the traces with extra copper wire and plenty of solder. The problem is the controller was like this before the shunt mod; it kicks on slowly and responds slowly to throttle. I think it's intentional, to keep it...

    bigger hub motor wires-Ground one phase to frame?

    I don't understand how connecting one phase to the axle would cause a short condition... Path of least resistance would be from the bike frame, cross the axle onto the phase. Where would that short to?

    bigger hub motor wires-Ground one phase to frame?

    I haven't seen this done much at all or even talked about (Might be a lack of searching) But wouldn't it be possible to ground out an entire phase to the bike frame, letting you have bigger phase wires into the axle?

    Custom Dropouts and torq arm

    Or make your own frame for 50 and spend the rest on either 'moar voltssss' or just a line of cocaine; either way, buying frames is expensive and you can build one in the time it takes to ship-If you own a welder. Hell, if there's a machine shop around and they have a pipe bender they can make...

    KT-3 LCD Not showing Watt draw

    That's probably it :( Well, looks like I'm getting a sine regen controller then... woe is me ;)

    KT-3 LCD Not showing Watt draw

    That's the thing; same brand controller. Same manufacturer. Are you saying the display might be calibrated for each controller? Hmm, that's pretty interesting. Would you know how to calibrate it? IMO if it were miscalibrated it would just show an incorrect value instead of nothing.

    KT-3 LCD Not showing Watt draw

    I have a KT-3 LCD (https://www.google.ca/search?q=kt3+lcd&espv=2&biw=1920&bih=955&source=lnms&tbm=isch&sa=X&ved=0ahUKEwivneW7tPbKAhUHmh4KHc_ZBDoQ_AUIBygC#imgrc=XPK_XrCZLNF-5M%3A) That worked fine, until at one point the hall sensors in my motor went. I fixed it after a while and moved everything...

    All in one Ebike Calculator!

    It's in there- Top theoretical speed is your max speed dependant on voltage and Kv; Type that speed into the input side and you'll see how many watts you'll need. I thought of adding it in, but it's a lot of extra code and turning a lot of math backwards on itself only to do something the user...

    Is this a good bike choice for a bafang bbs02 conversion?

    If you own a welder in all honesty I'd recommend making your own frame. It's hard to buy a frame for a bike with dimensions required for batteries, the suspension you'll wish you had and the sizing you'll want. It's just 30$ of steel and a 20$ donor bike to take cranks off. I can help you with...

    Custom Dropouts and torq arm

    That's straight up goddamn dangerous mate. Close your eyes and imagine it starts bumping loose-next time you twist the throttle the shaft will want to spin counterclockwise. It'll push against the left side of the dropouts towards the front, pushing the back of the shaft against the opposite...

    Coast and Burn (Pulse and Glide) Calculator

    If you'd like, throw some of the equations at me and i'll stick them in java and build a quick GUI in it (Like https://goo.gl/23d62r) Looks like a pretty neeto setup you've got. If someone had mentioned it to me, i'd call them crazy saying pulse and glide would be more efficient than straight...

    Anyone have front hub accidents even with torque arms?

    Your build looks very solid imo, nice thick torque arms and low motor power. For my build I needed to get to and from work and had no other transportation available due to unforseen circumstances so I threw a 1000w front hub on an old (1980's) carbon steel road bike frame using a front wheel on...

    All in one Ebike Calculator!

    I've yet to find any EV Calculators. I found some other calculators but those are geared towards finding gear ratios. None of them help you find acceleration, watt draw @ speed or take hills into account AFAIK. Plus even if a couple seperate calculators can, in aggregate, do all that, they don't...

    Hahahah, I'll put the google drive link up, but it's been randomly blocking people because it's a jar file xD 'security issues', If I could make a 20kb trojan i'd be working for DARPA

    All in one Ebike Calculator!

    Run it like you would minecraft; you'll need java. Don't extract the .jar, run it using java. You can get it here if you don't have it: http://www.java.com/en/download/windows-64bit.jsp Pretty big download-but I'm surprised you wouldn't have it.

    Take a look at my calculator-You'll know exactly what you need. 20kb, it's free and the imgur link has a screenshot. You'll need java tho http://imgur.com/gallery/1BJ4aTp

    Front Hub Motor on a Carbon Road Fork, with what mods ?

    AFAIK some hub motors actually run backwards due to the gear reduction-Two stage planetary requires the motor to run backwards to get forwards at the final stage.

    Battery care in the cold

    Open the pack and slap in one of these http://goo.gl/sA811w then add some foam to the outside and tape. 20W is almost no drain compared to a 500Wh pack. Go fishing for 3 hours, that's 60Wh drained (on 48v that's 1.2Ah gone) and they'll keep your battery warm. More than worth the price.
