DESIGNED FOR Peloton BIKE AND BIKE+ – The Peloton light weights fit perfectly in the weight holders on the back of your Peloton Bike or Bike+ to make storage easy and convenient.
ARMS AND TONING EXERCISES – Peloton weights are available in pairs of your choice of 0.5, 0.9, or 1.4 KG. weights. These Peloton accessories allow you to get a full body experience by targeting muscles you might not have engaged during a ride.
VERSATILE – Peloton weights can be used for workouts on and off the Bike, including Peloton Guide workouts. They are perfect for beginner arm workouts, shadowboxing, toning exercises, and more.
DURABLE – Cast iron dumbbells can withstand wear and tear from frequent workouts including repeatedly inserting and removing the weights from your Peloton Bike or Bike+ weight holders.
NONSLIP GRIP – Peloton weights are designed with a rubberised coating to help you maintain your grip during your sweatiest workouts and reduces noise and vibration if the weights are ever dropped and when stowed.
ERGONOMIC DESIGN – Peloton weights allow you to comfortably wrap your hands around the handlebar while the flattened edge of the dumbbell heads prevent them from rolling.
EASY TO CLEAN – Designed with materials that are sweat and salt resistant to make cleaning easy.
