8.5x2 inner tube (140mm diameter) for Z8 Pro Vsett 8 & 9

Do not choose your spare parts lightly: your experience as an e-scooter rider depends on it.

This is somewhat the motto of the Wattiz team, whose enthusiasm leads them to select only high-quality items to equip your electric scooter.

This is particularly what drove us to offer you this model of 8.5x3.0 Z8 Pro inner tube Vsett 8&9, whose features might just delight you as you read through these few lines.

Is this product right for your tire? Which of its features make it a spare part suited to your needs? What are the benefits of choosing Wattiz’s quality to purchase it?

Welcome to a world where quality, safety and comfort are rights, not privileges.

From the Z8 Pro to the Vsett 9: a kaleidoscope of efficiency

Ease of use, price comfort, compatibility comfort: the arguments in favor of this inner tube are far from trivial.

Weighing no more than 0.07 kg, this product created by the Hota brand also puts the durability of its rubber to the test on the least welcoming roads without losing pressure.

Indeed, the pressure this spare part can withstand under a weight of 70 kg ranges between 2.4 and 3.4 bars (depending on whether you place it at the front or rear of your vehicle) to ensure the most comfortable cushioning possible.

Designed to fit the front wheel of the Z8 Pro, it will also perfectly suit those of other electric scooters such as the Vsett 8 and even the front and rear wheels of the Vsett 9.

However, you will have the option to adapt it, in general, to other types of vehicles as long as you respect dimensions of 8.5 inches in diameter by 3.

Keep in mind, though, that its angled valve was specially designed for Vsett and Z models, so you will need to be careful when installing this item if your electric scooter turns out to be somewhat different.
