as an engineer i was skeptical at first but after trying it out im impressed it does what it claims delivery was quick and it handles wet conditions well though i wonder if itll hold up over time for the price its a solid upgrade if you want more from your bike
- Pros: the controller is incredibly easy to install and fits most bikes without any guesswork, the display stays clear and functional even in heavy rain, and it really boosts the bike's power making rides much more enjoyable
- Cons: could be wrong but it might not be the most durable option long-term, and the power management while slick could be a bit overwhelming for someone not used to tweaking settings
