Did you know?
The 31″ (80 cm) and 39″ (100 cm) Hoppi are hopper balls. The 47″ (120 cm) Hoppi is an exercise ball with handles, not for hopping.
The ball with handles: hopper balls in 31 and 39 inch, an exercise ball in 47.
Meet Hoppi, the Bigens ball with handles. Grab on and hop, bounce or just sit back: a supersized ball for supersized fun, on your own or in a group.
Pump it up with a low-pressure air pump until it reaches its full size, then stop. When you're done, let the air out, fold it up and store it somewhere dry until next time. One rider per ball, please.

Every size we make, side by side and drawn to scale.
Think about who's playing and where. The size guide above shows every size side by side. Still not sure? Email us at hello@bigens.com and we'll help you pick.
Give it clear floor of about one and a half times its width. Deflate it in minutes and it folds flat.
Use a low-pressure air pump for inflatables, by hand or electric. Inflate it until it reaches its size and stop there. Never use a compressor or a high-pressure pump. Pumps join the accessories soon.
Yes. Grass, sand and smooth floors are perfect. Keep it away from sharp objects, gravel, heat and open fire.
Let all the air out, fold it loosely and keep it somewhere dry, out of direct sunlight.
