Centrifugal Pressure Resistance (CPR) provides the most realistic simulation of riding a bicycle ever!

The 1up Trainer has a functional range for continuous operation from 4 watts (5 MPH) to over 3,000 watts (42 MPH).

1up Trainer have the widest range of resistance in the industry (4 to 3,000 watts). There are even enough watts for two world class riders on a tandem! But it also accommodates light exercising for Grandma, and every level in between.

This new resistance technology outperforms fluid, magnet and wind trainers. You can't zing this trainer up to an unrealistic 40 or 50 mph. If you can pedal your bicycle 30-mph outdoors, then that's how fast you will be able to pedal your bicycle on our trainer. 20 mph feels like 20 mph, unlike other trainers. You can not over power this trainer – in fact you can even simulate sprinting, intervals and hill climbing. The CPR provides no resistance until 7 mph for easy starts or light training. After 7 mph resistance increases exponentially. The 1up Trainer has a RC (resistance curve) adjustable system. The RC System allows the rider to change the resistance curve in the trainer. The RC System is "Weight Specific" for strong riders over 200 pounds. The CPR is also the quietest and smoothest system available. 1up Bicycle Trainer are fluid free, NO LEAKS! CNC machined with less than .001 of an inch run-out.
