A CYC Photon kit will replace the non-functional Copenhagen Superpedestrian Wheel hub motor on my 1987 Schwinn Voyaguer touring bike.
Just ordered the Photon 750W mid drive motor with a CYC 52V 15 amp hour battery.
I selected a 42 tooth chainring with 175mm cranks.
This increases my crank length 10mm from the 165mm cranks on my Schwinn Biopace triple chainring set.
The Schwinn has a 50-44-28 chainring set and a 14-16-19-22-26-30 rear hub.
I was usually on the 44 tooth ring which led me to select the 42 tooth rather than the standard 38 tooth ring for the Photon.
I have assumed a 42 tooth ring would meet my road bike needs better than a 38 tooth ring.
I am very excited to re-electrify my 1987 Schwinn with a mid motor drive kit.
The Superpedestrian Wheel hub is no longer usable since the Superpedestrian Company does not support the App needed to use the Copenhagen Wheel... the Superpedestrian Wheel hub motor/battery combo made my bike extremely back heavy and unbalanced.
I was in love with the Copenhagen Wheel until Superpedestrian let all Wheel owners down.
