Well it works exactly as described........but there are a couple of smaller issues ( which I think you would have regardless of what pedelec)
out I went this morning, felt great, prefectly like a natural cycle in the country on a fine morning.....
I think to be honest that with a controller this powerful, you would need the 3 way switch, or another method of power control, because at 30mph, 15 amps is great, but at traffic lights, 50amp peak isnt exactly whats required
I disabled cruise this morning, as the peddaling kept setting the cruise, and I wanted a more responsive test
4 settings available in my setup
0...pedelec switched off ( really do recommend a switch for this)
1...cycle analyst engaged.....15mph limit, 6 amp limit
2...switch 1 setting 70%.....18mph rough limit, no current limit
3...switch 2 setting 100%.....24mph rough limit, no current limit
4...switch 3 setting 120%.....30mph rough limit, no current limit
startup in cycle analyst in low gear is nice and smooth, not too much power, nice fast cadence, and throttle slowly works up to limit speed...this mode is great for the feel of actually cycling, as once you get over the power / mph threshold, its your legs providing the balance of power, but without the hassle of trying to balance the throttle, or cruise mode, where the controller will just pump more amps to keep the speed...
Startup in switch mode 1-3 is ok, but there is no current limit, so you will go to top end speed quite quickly, hence the reason for the 3 way switch recommendation..setting one is great for about town or junctions, 2 is a good alrounder for long straight roads countryside etc, and 3 is for when you just wanna hammer ( not wet icy etc..)
Now the smaller issues are just two really
1...like most pedelecs I've found that although it works, its not a torque sensor, so if you pedal faster, the motor will accelerate, so your for instance coming up to lights, you drop down gears for an easy start, but whilst you wanna slow, the motor will accelerate.....ebrakes will cancel it of course and an off switch will also be a help.....
numbrt two is a little bit more painful.....throttle regen....now as electrobent has described, there is a throttle regen effect on the infineon controllers...if you let go of the throttle above 10mph, the motor goes into a light regen mode....can be cancelled by holding the throttle just a little open, but if you arent using the throttle...here is what happens
your heading for a speed ramp, you stop peddaling just before, bend knees and stand up , but youve stoppped peddaling, so throttle regen kicks in at the point you are standing up.......hmmmm
Cure of course.......use a dual pole on switch for the pedalec, on one side, the throttle pass through, on the other side, a 12k resistor....this will pass a constant about 1v to the motor, cancels the throttle regen, current is about 0.05 amp...just remember to turn off if you are going to leave the bike standing with the battery connected.....
But if you use end bars, then you have more control, so pedal for power, light pedal for coast, stop pedal for braking, all without leaving the end bars....guess its just getting used to it
overall its great, mostly due to the fact that as a voltage output independant of the controller, you have many many options to manipulate the output whilst cycling.....personally for me the 3 way infineon switch really fine tunes it.......and the cycle analyst limiting works perfectly with it ( resistor in line of course)
For Gm controllers, you could work a 3 way switch with different resistor values on each flick, light medium and no resistance.......should cater for everything
any questions
