Stunts can be performed on a hardtail mountain bike with a hub dynamo, but it's important to consider the limitations of the bike and the dynamo.

Additionally, the hub dynamo may add extra weight and resistance, affecting the bike's performance during stunts. It's important for riders to assess their skill level and the capabilities of their bike before attempting stunts on a hardtail mountain bike with a hub dynamo. **
