Brushless Controller for Electric Bike

i was expecting a big upgrade for my electric bike, and overall, it delivers on making rides smoother and more responsive. the power increase is noticeable, especially on hills, and the display helps me monitor battery and speed easily. installation was mostly hassle-free, though i had to make sure everything was aligned just right. it's held up well over the months, no signs of wear yet. not perfect, but it does the job well for the price, and i'd recommend it to others looking for a reliable boost.
- Pros: it definitely gives my bike more pep, which is great for getting around town with the kids. the display is handy for keeping an eye on things without being distracting, and it was pretty straightforward to install myself, saving me a trip to the shop. it feels solid and hasn't shown any issues with daily use.
- Cons: it might be a bit too powerful for some setups, and i had to double-check the fit since it's snug on the handlebars. the efficiency boost isn't as dramatic as i hoped, and it could be more user-friendly for tweaking settings without extra tools.
