As someone who enjoys tinkering with gadgets, I picked this up on a whim hoping for an easy upgrade. It does the job for basic improvements, but it's not without its flaws. The installation was mostly simple, but I ran into a few snags where things didn't align well, and I had to spend extra time tweaking it. The lights are decent but could be better for those late-night rides in Houston. Overall, it's an okay product if you're looking for a budget-friendly option, but don't expect top-tier performance. I'd say it's functional but not exceptional.
- Pros: The kit includes a lot of useful parts like lights that make me much more visible when riding at night, which is a big safety plus. The thumb throttle and brake lever feel responsive and give good control over speed, and it was pretty straightforward to set up on my electric bike without needing special tools.
- Cons: I didn't like it that the compatibility claims might be a bit overstated; it didn't fit perfectly with my setup even though it should have, and the build quality feels a bit cheap in some areas. The lights aren't as bright as I hoped for really dark conditions, and I had to make some adjustments to get everything working right.
