Re: Tangent Mid-drive support or replacement components?

If anyone has the output part for either the 3kw version (with bigger holes) or one for the last generation (i think) I'd be interested. This is the part that threads the freewheel, they are expendable since a broken freewheel cannot be unscrewed. Mine failed in worse ways tho. Maybe we should try t...

Re: GNG / CYC X1 Pro 3000w

Throttle response is damn near perfect and startup excellent with the Talon and HV80. I just can't seem to break through to the higher amps without the violent shaking (bike almost self destructs). ... As it looks now, the only way to get some high power from this motor is going for voltage and app...

Re: GNG / CYC X1 Pro 3000w

Yeah officially it’s 12s only but it survives 57.4v without any hassle. At full 58.8v it may complain and warn tho, but I rarely go that high. Same goes for the HV80 and probably other CC ESC.

Re: GNG / CYC X1 Pro 3000w

I'm experimenting and aiming to push peak 100 amps at 52v through the gen 1 motor using a CC Talon 120 controller. I only run offroad and more interested in torque than top speed at this point. Take-off is super smooth and full throttle with wheel in the air is also flawless, however when under real...

Re: Dave's 80:1 RC mid drive kit build log

Hi Knurf. So we are in lock down here so I am tempted to focus on the bike for a while. ( Need something to take my mind off the stress of being a small business owner right now. ) You mentioned that it could be some kind of short from the phase wire and the casing. I couldn't measure anything when...

Re: Dave's 80:1 RC mid drive kit build log

Hi everyone. Having huge problems with my tangent ascent 6kw. Looking around with an scope I found that any time the motor was turning over I was getting nasty noise on the CA output signal. The good news is that you probably got the latest, most iterated version of the Tangent. The bad news is tha...

I'm also interested in the Nucular [sic] controller, and would REALLY love to try it out on this drive unfortunately their site has a 4 month lead time and presumably that's before coronavirus screwed up china production. Anyone got one for sale? I have seen 3kw from mine at least. It's a lot to as...

Re: GNG / CYC X1 Pro 3000w

From memory, prop mode, insensitive current limit, high frequency pwm (24khz?) to minimize spikes. When racing super tight trails I'm usually geared for a top speed around 26 mph. The sensorless autostart works great with this gearing and there is loop the bike torque off the line. But of course wi...

Re: GNG / CYC X1 Pro 3000w

The throttle is thru a CA but in pass thru cuz I haven't had great results with the CA torque control and I'd rather use a very good speed control than a poor torque request. Maybe that one's a programming issue, but I dislike feedback controllers. Ok I see. What are settings are you running on the...

Re: GNG / CYC X1 Pro 3000w

Can anyone provide a better racing controller for the X1 rev2 (newest) than a Castle HV160 12S ESC? The criteria: --instant response, as fast as I twist, including quick on-offs --instant high torque loop the bike if you're not careful start from zero, need low gear OK --Several kw --ideally, torqu...

Re: Elecycle online store

I bought a MXUS 1000W from them well over a year ago. It arrived and worked just fine (can't remember how long shipping took, but probably normal china time). I wanted a complete wheel (and the order even says 26" wheel size) but the shipment contained just the unlaced hub motor. They did confi...

any tips tricks or voodoo dances suggested would be most appreciated before destruction and inevitable go to Phaserunner/CA3. Thanks and cheers! Not really, but I do feel that the controller and software are pretty horrible. Lots of little quirks. I have switched to a CC/CA3 combo and the motor/gea...

Re: Dave's 80:1 RC mid drive kit build log

I think I just fried my tangent kit's cycle analyst(or maybe esc) but I heard can't get in touch with Dave. symptom : When I connect battery, no arming sound at esc and cycle analyst backlight is blink once, and no text and no response. How should I test which module is dead? I'd guess that your ES...

I'm not running a thermal sensor and my bike doesn't have a build thread. Thanks for the heads up on the water! I will keep that in mind. Maybe I can pot the CC, but rarely do my bicycles get wet.

Has anyone gotten the throttle to work well on the stock 14s controller? It is terrible, even with the latest firmware.

Re: GNG / CYC X1 Pro 3000w

The problem with tightening it is you might crack the glass overdoing it. They now include full alu side plates for free. I imagine that would deal way better against moisture.
Yeah definitely shouldn't torque those too hard. I was referring to the ones on the opposite side, drive side.

Once cyc work the kinks out, the Ascent will be the choir boy of mid drives, not the god. Loud, expensive, low voltage, incredibly hard on drivetrain, outdated.
