Yes, a 77-inch 4K TV would likely be too extreme at a distance of 35 meters. At that distance, the TV screen would appear quite small, and the details of the 4K resolution would be difficult to appreciate. It would be more appropriate to consider a smaller TV size for that viewing distance, such as a 55-inch or 65-inch TV, to ensure a more enjoyable viewing experience. **

Yes, plush toy helmet covers are allowed in Switzerland as long as they do not obstruct the rider's vision or impair the functionality of the helmet.

A 77-inch TV might seem small in an area of just under 30 square meters, as the size of the TV relative to the size of the room could make it appear less impressive. In a smaller space, a larger TV might dominate the room and provide a more immersive viewing experience. However, the ideal TV size ultimately depends on personal preference and how far away you typically sit from the screen. **

The speed of a bicycle is not solely determined by the size of its wheels. Factors such as the rider's strength and technique, the bike's weight and design, and the terrain being ridden on all play a role in determining speed. While a 28-inch bicycle may have a slightly higher top speed due to its larger wheel size, the difference in speed may not be significant enough to be noticeable for most riders. Ultimately, the speed of a bicycle is more dependent on the rider and the overall design of the bike rather than just the wheel size. **

No, you cannot replace the 20-inch tires with 24-inch tires on a 20-inch bicycle. The tire size must match the wheel size of the bicycle for proper fit and function. Using a larger tire size on a smaller wheel can cause issues with clearance, handling, and overall safety of the bicycle. It is important to always use the correct tire size recommended for your specific bicycle. **
