Full-face helmets provide more protection for the face and jaw in the event of a crash, making them better for more aggressive and high-speed cycling such as downhill mountain biking or BMX racing. However, for general cycling, half-shell helmets are often preferred due to their lighter weight, better ventilation, and less restrictive feel. The choice between the two depends on the type of cycling and the level of risk involved. **

The hub dynamo may only light up when the bicycle is stationary because there could be a loose connection or a faulty wire that is not making proper contact when the bike is in motion. It is also possible that there is an issue with the dynamo itself, such as worn-out components or internal damage, that is causing it to only work when the bike is not moving. It would be best to have a professional inspect and diagnose the problem to determine the exact solution. **

The solution for the Wii Fit Plus bicycle is to ensure that the Wii Balance Board is properly synced with the Wii console.
