Review on CYCPLUS Bike Computer with GPS and Wireless Connectivity, Backlight for Night Riding, Waterproof Speedometer Odometer, Extended Battery Life, Enhanced Professional Data Analysis by Jeremy Floyd

available. It just doesn't have a GPS signal in the wooded area where I live and drive most of the time. Loss of signal introduces significant errors compared to actual distances traveled. When I was driving on the street near my house, the unit of measurement was 5.7% smaller. During yesterday's 22-mile trip on the C&O Canal towpath, the error was as much as 30%! The Cycplus Wireless only logged 15.4 miles from an actual 22 mile ride. For those familiar with the C&O channel, I went back and forth from mile 50 to mile 39. Almost the entire 11-mile stretch is heavily forested. I don't think the device is defective as I'm sure the signal loss is related to the treetops. The guide to setting up and activating the device was pretty good. If you drive outdoors most of the time, I think this device will suit you. As for me, I'll just keep using my wired SIGMA module. Never missed a beat in 14 years.
