Re: GNG / CYC X1 Pro 3000w

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. I've had some success by picking them apart, scraping off original thermal paste with a toothpick, coa...

Re: GNG / CYC X1 Pro 3000w

Meanwhile my 12S Castle HV160 continues to flawlessly drive this thing with INSTANT throttle response and totally reliable power every time. They're only $250. Just watch it with the water... I've killed more CC ESC than I want to count with water damage :( Biggest advantage the stock controller ha...

Re: GNG / CYC X1 Pro 3000w

Has anyone gotten the throttle to work well on the stock 14s controller? It is terrible, even with the latest firmware. Super slow and when you hit the throttle from a stop, the motor oscillates and then shuts down. On PAS it is fine. I can't understand why a simple throttle control could be so har...

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.

Re: GNG / CYC X1 Pro 3000w

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 Loud, expensive, low voltage, incredibly hard on drivetrain, outdated. I wouldn't buy it if they were the same price. I feel this is the case already (mixed feelings about this..), this motor handles heat in a...

Re: GNG / CYC X1 Pro 3000w

Just got my kit up and running. My first impressions of the throttle and controller are mixed, but the motor is a solid piece of hardware. It's nice to be able to configure in the field with bluetooth but the update cycles are surprisingly slow. Downloading/uploading settings takes way too many seco...

Re: GNG / CYC X1 Pro 3000w

Anyone has the pin-out for the hall/temp connector? My unit is being shipped right now so I haven't tried it out yet, but if there's such a huge delay in the throttle (sounds totally unusable), I'll be fine using a Castle HV80+CA3 instead.

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

Maybe if you guys ask Dave, he will send a CAD file and drawing for the part so you can get a quote from a machine shop for a run of 5 or 10 (not sure how many drives have been sold) replacements parts. Unit cost for a handful will be a fraction of the cost for one. Seems like the right thing to do...

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

Yeah I did something exactly like that on one of my old units. The JB epoxy is heat resistant but the bond is relatively weak and it is down to the two wedges to take most of the load. Mine broke after a few rides at 2500w, but I also had a problem with the pedal crank freewheel breaking up and pull...

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

I think it is one off the first generation. Going next week to a machineshop to ask for a solution. The drive is only 3 Kw. The torque is high when the bike is accelerated. Try to weld it with JB cold weld and it lasted 10 km with only 20 amps. on the controller. Se what te Guys at the machine shop...

Have a machine shop make/copy the adapter out of steel. Yeah this is actually something we should look into if we want to keep these things spinning for a little while longer.

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

No but just get a standard castle creations hv80, minor programming changes, that’s it. The phase runner is hard to get to behave well with a 3210, had no real great success with that. Also consider opening the hv80 and glaze it with silicone conformal coating since they are highly susceptible for w...

Tony Vo on the Facebook group was running 8-9kw peak through his... It seems to be overbuilt for 3500w. Since both controller and motor temperature is monitored it will take a really big burst to kill it off I suppose, electrically at least.. 4-5kw is my sweetspot, but more is always fun! Just orde...

Re: GNG / CYC X1 Pro 3000w

Wow I want one!

I'm going to assume that the motor temp measurement in that video can't be accurate, looks more like ambient temp. A small motor like this pulling those amps would heat up quickly (maybe something similar to that controller temp)?

Re: bluetooth BMS?

I'm using one of those Smart BMS with display from the IC GOGOGO guys, the 150A version with display. It is managing a 14s rc lipo pack. It's been working nicely for many months now. I'm powering a bike that pulls up to 140A at 52v. The current is controlled by a CA3 and a shunt. Lately I got a few ...

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

Proud of the frame for lasting so long or the kit for having the power needed to snap it?:)
Haha obviously both :)
But I'm probably not going to venture much into 4kw land with the replacement frame.

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

Good effort! What kind of mileage do you have on it?
Maybe 5000km human powered + around 4000km under Tangent power, more than half spent commuting. I could feel it flex considerably at peak power, so I'm very proud of it..

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

Using my old 3210 in a 40:1 gearbox, a large front chain ring, a snowy uphill section and more than 90 amps, I finally tore through my frame (Specialized Epic 2006). It cut the weld clean through, in about the beefiest place of the frame, my money would have been on somewhere in the complicated link...

Re: Voltage regulator no juice

I keep the grounds (negative leads) separate for each voltage I'm running. So the 48v, 36v, 12v and 5v circuits are all independent once the voltage conversion has happened. Yes, that appears to have been my problem! I disconnected the regulated ground from the ESC and now the lights don't even fli...

Re: Voltage regulator no juice

Interesting points, thanks! All forms of measuring are made a bit complicated, by the fact that i need a real load on the bike for this to happen. I do have a BMS that monitors max/min voltage at least but the regulated voltage would be very interesting to get a hint of. But that ground problem.. I ...
