I've been very happy with this Harrison bike overall.
At first, I honestly thought there was something wrong with the resistance knob. It felt different from what I was used to, so I contacted SAC thinking it might be a defect. Their support was excellent. They responded quickly, were clear, and walked me through everything without any hassle.
It turned out there was no issue at all. The bike is actually more advanced than I expected, and I just didn't understand how to use it properly at first. Once I got it set up correctly, everything made sense.
The electronic and magnetic resistance is very smooth and precise. The force feedback feels strong and controlled, not like old friction systems. When connected to Zwift or Rouvy, the bike delivers very realistic data. Speed, power in watts, and RPM all respond accurately to effort and resistance changes, which makes the riding experience feel much closer to a real road ride.
Overall, solid build, advanced tech, and great customer support. After the initial learning curve, I'm genuinely impressed with how well this bike performs.
