Returned my Hiboy KS4 Pro and bought an iSinwheel GT4 instead thoughts?

Hey everyone,

I recently returned my Hiboy KS4 Pro and decided to go with the iSinwheel GT4 instead, and I’m curious what people here think about that choice.

My KS4 Pro experience wasn’t great. On paper it’s advertised at around 19 mph, but in real-world riding it felt slower. The torque was pretty weak, especially on hills. I weigh around 190 lbs, and even small hills (around 5% grade) dropped the speed a lot, sometimes to 6–7 mph. The acceleration also felt delayed when pressing the throttle.

Range also didn’t feel close to what was advertised unless you ride very slowly.

Because of that, I returned it and ordered the iSinwheel GT4. The specs looked better for what I need:

Higher top speed

* Bigger motor

* Better hill climbing

* More range on paper

I mainly ride in areas with small hills and some longer routes, so torque and real-world performance matter more to me than just specs.

For anyone who owns or has tried the GT4, how has your experience been?

* How is the hill climbing in real life?

* Does the range match the claims?

* Any reliability issues I should know about?

Would love to hear honest opinions before I start putting serious miles on it.

Thanks!
