Product ordered was timely delivered; well packaged. Have had three issues with Swytch system: (1) Lights for status of battery is confusing becaus difference between what appears on the battery itself and what appears on the control device on handle bar. (2)Handle bar device is awkward to scroll/turn off while riding when battery is not needed and then back on to resume battery assist. (3) Mounting sensor system on crank arm is challenging to install on arms that have tapper and rounded side. The requirement for proximity to sensor on frame (post) is hard to achieve and zip ties are not as tight as desired because the ties are secured to a tapped/round surface.
