Is my bike compatible with Tacx trainer? Tacx trainers are compatible with a wide range of bikes, including road, mountain, and hybrid models. Most trainers offer adjustable settings and adapters for different axle types and wheel sizes. While most bikes that fit the above criteria should be suitable for use with a Tacx trainer, we recommend that you check your bike’s specifications against the trainer's tech spec to ensure integration is possible. Can you use the Tacx without a subscription? Yes, Tacx trainers can be used without a subscription. While a subscription to apps like Tacx Training can enhance the experience by offering real-road virtual simulations and additional advanced features, the trainers function just fine in basic modes without the need for supporting software.
