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. The hardtail frame may not absorb as much shock as a full-suspension bike, so riders should be cautious when attempting stunts to avoid damaging the bike or injuring themselves. 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. **

To change the rear wheel hub on a mountain bike (MTB), you will need to first remove the rear wheel from the bike.
