The ride
Not just rocking. A supported, floating feel.
ULTRA distributes support under the trainer and matching front support across Motion Balls. The system can respond to small shifts in your weight, creating a sensation riders describe as floating. Your experience depends on the configuration, rider weight and riding style.
Your level of support
Motion Ball firmness, count and position change the response. Tune your configuration between rides.
Built around your trainer
The system follows the trainer footprint and remains easy to store, move and service.
