Why do we need a sweat guard? When using bicycles or exercise bikes indoors, we tend to sweat heavily. Sweat can cause damage to metal materials. If sweat drips onto the frame or other parts of the bike, it can lead to rust and shorten the bike's lifespan. Sweat can also damage floors through the anti-sweat netting. Additionally, it helps prevent slipping caused by sweat. The sweat guard features a triangular design, wider at the front and narrower at the back. The narrower rear end ensures it doesn’t interfere with your legs while riding.
