Cycle Analyst & Infineon 25A Controller: Enabling Limits?

Renissance has a page that describes what needs tb done to enable limit settings on the Cycle Analyst "Stand Alone" model CA-SA (http://www.ebikes.ca/drainbrain.shtml, scroll down to #8).

But there are no pix of what to look for inside the controller - e.g. "Th pad in PCB".

The Endless-Sphere threads are so extensive/detailed/helpful that I'm hoping somebody's been there already and documented it.

Anybody know of a thread?

The Th pad is in your Cycle Analyst, not your controller. If you open the back off your CA and look inside, you will see a pad, labeled Th, with nothing soldered to it.

Hooking this up to the right location inside the infineon controllers is a little tricky, since there isn't a conveniently accessible solder point after the series resistor to the throttle signal. You need to branch off one end of the surface mount resistor package and hook the diode or wire up to that.

I found the "Th" pad OK.

But, reading between the lines of your reply, I conclude that the controller's innards are best left untouched by the likes of Yours Truly.

My agenda was that I had hoped to invoke the CA's limit functions using my 9C setup to help me explore how low I could go watt-wise and still fulfill my requirements.

Just eyeballing the CA over a couple of weeks seems to have accomplished the same end and I am confident enough that I can live within the eZee hub's limits that I just (as you obviously know, since you're processing the order on Monday) ordered an eZee setup.

What I'm hoping is that I can live with the increased noise/decreased power in exchange for:

• Half the weight
• Disc brake
• Better visual stealth
• No cogging
• Operability in steady rain without having to bag the controller
• Complete CA functionality
• Ability to substitute any one of several double-walled rims if I want to run a bigger tire than the stock rim is made for.

If I decide I can live with eZee, end-game will be DeWalt batteries and only carrying as many as I think I will need for a given ride - which promises to cut my battery weight by at least 50% and maybe as much as 70%.

If nothing else, I'll be able to discuss the tradeoffs between 9C/direct drive and eZee/geared in some detail from actual experience.

I will wait your experience anxious, Petecress... I think that the "quality concern" is real and really important for Ezee guys... Please, report your experience here... I have a 9C (9x7 windings - E-bikekit) and love the motor and silence, but the wheel build/construction really bother me.

I do not recall explicitly expressing a quality concern - although I ranted about a specific informational issue for awhile.

Having said that, I would opine that if the Chinese ever get quality control down pat, much of the rest of the industrialized world - including the USA - is going to be in deep kimchee.

I'm finding the eZee kit tb 100% satisfactory.

It comes on a rim that looks pretty good to me - and it's a name brand: Weinmann.

A sticker on the rim explicitly states that it is for tires up to 1.75" and that if the user wants to mount anything bigger they'd better check with the tire maker. I'm running a 1.5" cyclocross tire and it's working a-ok for me.

FWIW, I'm pretty neurotic about noise and expected the eZee's geared motor tb a problem. But so far it has not been. It's definately noisier than the 9C, but neither one bothers me.

OTOH, the eZee has started making an additional noise as described in http://endless-sphere.com/forums/viewtopic.php?f=3&t=16589&start=0

I'm not sure whether this is a feature or a bug. I don't *think* it was making that noise out of the box... but I wouldn't bet the mortgage money on it bco the excitement of trying the new motor.... We'll have to see what Justin says about it. This noise doesn't bother me either - but if it's indicative of something wrong inside and fixing it can avoid some sort of failure, I want to know.
