I did a weigh-in with the battery: with/without method. Diff: 5.8lbs pretty close. Accuracy 0.2lb.
That's actually very impressive.

Tominfaribo said:Here's Rakesh reply on Regen:
Regen is active all the time. Any time energy is going back to the battery for a fraction of a time, the regen indicator comes on. Although while riding it is quite low. In -1 to -5 modes, regen is intentional as motor becomes a generator. Steeper the hill or harder the pedaling, more the regen. However regen stops if battery voltage exceeds 43V in 36V models and 55V in 48V models.

No torque arm needed or maybe it's on the other side?
Bike_on said:My Falco 500W system was designed as a PAS, with the throttle option. I added the throttle because the PAS response was not giving me enough continuous watts for all my leg effort. (call me lazy or old, but I needed more watts!) The throttle allows me to feather in 100-300W continuously, OR go full Thottle.
Full T puts out 1080W, 30A on a fresh charge and holds it. That was a surprise for a 500W system to me! Ah..nothing's free. On hot days, after riding maybe 15-16miles, sometime sooner, i get a power foldback to 120W for 4-5 min, then power resumes.
Rakesh confirmed that is a thermal limit in the motor. The limit is set in hardware (resistor) and a sw change can't
fix it. That's the bad news.
The good news is that Falco has analyzed and determined that the current temp limit (100C I think) is too conservative and they are raising it to 120C. Don't quote me on those specifics, but ballpark from memory. So the newer motors will have a higher threshold.

since EPLUS was designed by the same company and the same leading engineer - Rakhesh.
Of course it has thermal protection but you cannot notice any cut-off . It Is very gradual when controller limits power on hot day while riding in level 9.
So FALCO also has those power levels which works so well , no need to "feather" throttle.
28mph with light pedalling drawing just 300-400Watts ? No doubt FALCO drive is super efficient.
How well FALCO WORKS WITH YOU when you pedal along?
EPLUS works wonderfully with rider , speed increase in like unison. Easly can reach 52-53km/hour /!!!!/ with pedalling, without pedalling easly can reach 48km/h.
Consider that is 36V drive not 48V. How is FALCO in that regard?
Bike_on said:I saw the HPC vs Stealth utube video. HPC has a 92V, 4500W hub. 62 lbs. That battery has rediculously energy dense with a psycho voltage. Not fair. It goes 45mph, but you can't add any pedal power. Full suspension. I forget eff when racing, maybe 60 whr/mi.

hcrider said:Miro: I recently purchased a Falco 500 watt 36 volt 11.6 ah torque sensing system and installed it on a 57cm frame Trek 7300, running 700c x 40 on the rear and 700c x 35 on the front. The bike doesn't match Bike_on's speeds, but it's good for 31 mph with my pedaling efforts. Not bad for an upright bike. The motor is absolutely quiet. I've only felt the motor get very hot when riding a series of steep rolling hills at 17 mph on the upside with strong pedaling, and I was pedaling briskly on the downhills in strong regen to put watts back into the battery and extend range. Most of the time on smooth roads I ride 16 to 20 MPH. It's comfortable at that speed. The motor will be just warm to the touch during such use. Range of the bike can vary greatly, depending speed, hills, wind, pedaling effort, and use of regen. On some rides of 23 miles, the battery has indicated that it is down to 20% capacity at the finish of the ride. Using regen and pedaling on downhill and some flat sections, same-length rides yield 50% battery capacity indications. It's a powerful yet fairly light weight system.
