I have a Sun EZ-1 recumbent bike. I usually ride 15 - 20 miles for about an hour and a half. My bike is a 24 gear with 20 inch wheels. I am a 71 year old who is experiencing the joy of biking once again, thanks to the Falco ebike system. After researching many different systems, I am so glad I decided on Falco. The gearless motor is silent, yet provides plenty of power to give me a wonderful ride without tiring me out. I love riding my recumbent bike now that it has the Falco kit. I highly recommend this system.
