Buyer Beware!! I wanted to add an emotor to our Santana tandem, and the Falco emotor system was recommended by a tandem dealer as about the only thing that would fit the 160mm rear dropout spacing. I paid Falco $2992.99 on April 5, 2021 for one of their emotor systems. It was finally shipped on October 14, 2021. After using it for only 353 miles it suffered some sort of internal malfunction that rendered it unusable. It seemed to be a mechanical issue, not electrical. Something inside the hub is preventing it from turning properly. Over the next 11 days I left 6 voicemails at the phone number the website lists for warranty claims with no response. I have also left voicemail and a text at the phone number that I believe goes to company president Rakesh Dhawan, also with no reply. I have emailed the Falco engineer who answered questions about the original order 6 times; after no answer times 5, on the 6 try I got a message that the email account is disabled. In June 2022 the tandem dealer was able to contact Rakesh Dhawan and I got authorization to return the hub and wheel (at my expense). UPS documented that Rakesh Dhawan signed for it July 1, 2022. I have heard nothing since. So, no, I cannot recommend Falco emotors. Are they still in business??? Anyway, don't throw your money away with this company. Oh, and the hub motor, when working, had totally inadequate low end torque for Vermont hills.
