Are there any out there that are truly silent?
The one motor I suspect is silent is the Falco, mainly because the engineer behind it, Rakesh Dhawan (also CEO), was the one of the chief engineers at Tidalforce and is adamant about creating a quiet, seamless drive. Any Falco owners out there who can confirm this? What other e-bikes or motors out there are silent or extremely quiet?

Haha as above. BAC I believe would do the trick, apparently Sabvoton also. Would avoid the 'sinewave' chinese cheap controllers as I believe it's more of an approximation rather than true FOC.Ohbse wrote:Any large hub motor paired with a sine-wave FOC controller is going to be pretty damn silent. My Cromotor+Adaptto is virtually noiseless. Same motor driven with a low quality controller is quite loud.
My least favorite discussions are speculative and hearsay ones. Lets not believe, lets know and be scientific. Setup a testing apparatus and measure sound output in decibels for various motors.deerfencer wrote:<<Motors like the Tidal force were louder than the Clytes.>>
I don't believe this claim for a minute--my 2005 TF S750X is dead silent, not just quiet, and I've ridden it enough miles and years to know. What you might have heard was probably brake pad rub or something mechanical, not the motor. I also personally know e-riders who have owned both TFs and Clyte-powered rides and who have expressed the exact opposite opinion, namely that Clytes are powerful but far from silent.
Anyone else with experience with both motors care to weigh in here?
