                              PHYSICAL MEASUREMENT WAY,

          NOT LOSE ANY ONE CYCLE DATA

                     GPS cycle computer is always effected by the signal intensity or weather situation;

                      the data is always a little lower than the actual data value.  C3 takes usage of the

                      measurement method of mechanism physical method and will record each time

                      according to the actual rounds of the cycle wheels.It is an alternative choice for

                                                      many pro cyclists' training before the race.

        Wireless Protocol

                  C3 takes usage of Bluetooth 4.0 protocol and can connect with

                Smart Phone, Bike Computer and Sport watches which are based

                on same protocol.

               Claim:      C3 cannot support ANT+ transmitting protocol;Some of gps bike

                  computers and sport watches from brands like Garmin/ Bryton/Polar/Wahoo etc.

                  can only support ANT+protocol, In this case, our C3 cannot paired with them. Do

                  clarify what is your device wireless protocol before purchase please. If it is no use

                  more than 3minutes, c3 will automatically enter into sleep mode; when you use it

                  again, you must enable the device by rotating the wheelone full turn at least.
