Can I still buy a drive kit from them ?
Sent a message to Dave but no reply.
Nope, if you really want a drive like this you either look for used or go with the CYC X1.

Check in Ogio 9800. No extra charge. First class on Dreamliner. It's the only way to fly.PaulD said:Ecyclist said:I built a drive for myself. In two days I will by flying with my set-up to Japan.
How are you going to get that bike on the airplane?
The regulations are not very clear. Theoretically there is no limit on how many 18650 cells you can take on board, but I can bet my ass that I couldn't get through TSA. I could ship them by sea or buy them in Japan. I chose option number two. They are already waiting for me in my friend's house. I just stuff them in a specially designed case and I will be on my way. After I finish with my trip I will send them by sea back to the US. It will take one to three mouths. I'm OK with that.Animalector said:So they are letting you fly with lithium batteries in a bike? I realise you can take bikes as checked luggage, but an ebike? didn't think so. Some more information would be awesome I think there are plenty of people who want to travel with their ebikes.

I'd guess that your ESC is dead (they are pretty sensitive to water as they come shipped from Dave - I've killed a few), it's way harder to kill a CA.sephespid said: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?

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 that there is no support, I think the project is abandoned by now. Dave was a real champ answering emails quickly and sending (free!) replacement parts and even partial units over the years.
I have blown quite a few CCs over the years, mainly due to two reasons. Most common by far is water/salt damage. Second is having poor connections to the phase wires and pushing huge power through that. The motor will stagger and sound bad and the ESC fireballs soon after that (quite spectacular)... I've never seen the problems you describe tho, and never modified the ESC setup (besides from waterproofing it myself).
Could there be some kind of short circuit with a phase wire and the casing? That could go in to the CC through the mounting and cause all sorts of craziness I guess. I know Dave did have a few problems with mounting and phase shorts during manufacturing, delivery of my unit was delayed because of this. Hopefully it's not the issue here, because then you're basically out of luck fixing it.
I really hope Dave returns some day with a new project (and a sweet discount for old customers.. I'd support him again any day).

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 it was stationary but it did look like an intermittent problem so perhaps its only during rotation that it shorts.
Perhaps even the vibration causes it.
Makes me wonder if its worth pulling the motor apart to look for an internal fault.
Have you done this before?
I don't have a lot of information on the tear down process which is a bit of a block.
Thanks for your reply though.
Peace, n.
nlealand said:Do you have a oscilloscope?
There are some really nice cheap units around.
I have a Pokit which is handy. The probes are really prone to falling off though.
The other easy option is grabing a $5 serve tester and hooking that up to the ESC.
If that doesn't wake it up your likely looking at a cooked unit.
Also I understand its pretty hard to kill the CA so that feels unlikely to me.
What exactly was happening when it went?

You will find all that info on bearings unless you don't have a kit.Ham said:Does anyone know the correct bearing for the internals of the gen 1 box? carrier bearings and cam bearings?
Thanks
