Accoring to the thisisant.com website the console of the bike has the following capabilities:
Heart rate (reception)
Cadence (transmission)
Power (transmission)
I don't have the venu, so I cannot guide you directly, but:
Power is not supported by the venu. Cadence should be visible to the venu as an external bike cadence sensor. Refer to the venu manual on how to connect external sensors. As for heart rate, enable heart rate broadcasting on the venu (again - refer to the venu manual if you don't know how to do it), and the refer to the bike manual on how to connect external ANT+ heart rate sensor.
