I would have to guess the limiting factor is motor heat and batt.

Yep , when you do some calculations the amps coming out of the battery is just huge.

I generally run on 65%-Progressive when commuting and 85%-Linear when racing. The motor has a heat protection and will cut off in case of excessive heat. This has been my case when doing the hill climbing race. Not very fast (so no cooling), but lots of amps to get me up there...

Yep, you got the translation right  ;)

For the 72v model, seems the project is on the backburner...

As for tunning the power delivery, it's done thru the Alltrax controller, however, this VOIDS your Warranty ! My Warranty was void within the hour I received my bike  ;D

The controller has an RS232 plug that is behind a seal. You need to remove the seal to access the plug.
Alltrax publishes a software to be able to change some parameters.

The most noticeable ones are "Max current" and "Throttle response". For registration reasons, the Quantya strada is provided with the max current set at 65% (which corresponds to 8kw).  According to my dealer (and from what I've experience so far) you can bump it up to 85% but you will have less range. Anything above 85% might damage some components especially if ridding hard.

The throttle response is a curve of how the power is delivered.  the Linear curve gives a direct response but might be a bit brutal in some situations. the Progressive curve is more soft and usable for day to day activity.

I've also got a new pulley (the "sprocket" on the motor) that is larger and heavier than the original one. Makes for a smoother ride.

For the last question, it's a tough one, can't remember every thing, I started setting up a wiki to document a bit everything, but I got spammed so I had to bring it down.

One thing that is difficult to find is DOT approved tires that are thin enough for the Quantya.

Hi there...

I'm the original author of the post in the french forum  ;D I'll gladly translate and answer to your questions ;-)

I live in Switzerland (home of Quantya). I'm an avid enduro rider (have a KTM EXC 300) and to a bit of MX and some desert riding in Africa.

I acquired the Quantya a year ago, mosty ride it to work, but have done some races to see how far I could go with it. So far I've done a couple of MX races (15 minutes races), a hill climbing race (never got to the top  :'( ) and an endurance race (more of a cross-country type of event) and I'll be doing another hill climbing race end of june...

VoilĂ  for the presentations  :)
