- It’s a Wheel on Trainer, which makes it quick and simple to mount your bike, so no need to get dirty with chain grease while taking off your wheel (as you would with a wheel-off trainer) - Its built-in rocker panel design gives it a side-to-side movement to simulate a realistic road-like feel compared to a typical rigid framed trainer - Fluid Trainer automatically adjusts the resistance level to increase/decrease the level of power output. - Can be used totally standalone without any power, app or subscription - whereas most smart/controlled bike trainers need to have a power outlet close by, as well as a subscription to an app that controls the trainer’s resistance. - Compatible with training apps like Rouby, Zwift, etc. - No issues. Works great. - Perfect for getting in a great workout without any traffic or bad weather - No need for a dedicated exercise bike! - if you are interested, please reply with a phone number that I can call or text you at (I have had problems with emails not being received or ending up in junk folders) Thanks!
