Re: GNG / CYC X1 Pro 3000w

You had to add a resistor to the throttle specifically for CA or would it also be needed for the stock CYC controller? Thanks Oh, no that's not needed really. It was something Dave did with the Tangent kit and I think it makes it possible to detect and handle a disconnected throttle connector better.

Re: GNG / CYC X1 Pro 3000w

Top stuff, well done for modding it and getting it how you want. I am still working on getting mine perfect, it's close. How did you get the domino connected: just rewire it to a JST connector? As for waterproofing it may be worth having a look at ACF50 waterproofer...aviation industry over here (U...

Re: GNG / CYC X1 Pro 3000w

I thought I'd share the latest changes to my CYC X1 (gen 1) setup, since I finally have it running and behaving the way I like. I desperately needed something to replace my decommissioned 6kW Tangent setup and I'm very happy that I think I found it! Setup: Bike: Giant Glory 2011 Domino throttle Cycl...

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

Fried my CC HV80 on my 3210 Tangent today (got it wet while doing a snowy trail ride). Castle Creations HV80's are easy enough to come by by I understand Dave used a custom made shunt for it to work properly. What are the chances I can buy a new HV80 and use the old shunt to facilitate repairs. Lov...

Re: GNG / CYC X1 Pro 3000w

When I load it too much it feels like the motor throws itself in reverse and then forwards again, really fast. I had the exact issue, a motor magnet was cracked. Ask cyc for a replacement motor core. Also if the inside of the motor surface is uneven, it might crack your new magnets too, so sand any...

Anyone having problems pushing more than ~50A (battery) to their CYC? I have a first gen and running it sensorless with a castle creations talon 120 and a cycle analyst.

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

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...

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...
