Folding bike motor kit for 20 inch wheels – NYCeWheels.com I saw this and wanted to know if there's a cheaper/faster option? Btw I don't know anything about putting on a kit on a bike but would consider buying cheaper parts and paying for the labor only if it's just as good or better than the above kit that's in the link. Btw how fast/far can 15 v take me? From some reading I see larger batteries mentioned so I know they exist and larger batteries usually mean more speed.
My current bike is a Tern, 20 inches. Thanks in advance.
