Bottom line
Typical of high-power fat-tire e-bikes, the GhostCat Saber S1 delivers quick throttle acceleration, high unrestricted speed, and strong climbing performance. Testers appreciate the responsive pedal assist, reliable brakes, and a comfortable ride over light off-road terrain. Though none test the full range, the 1,800Wh battery capacity impresses. However, the bike breaches e-bike laws, the throttle is overly sensitive, and pedal strikes are a risk. The high weight and inaccurate sizing are further drawbacks. Nonetheless, testers consider the Saber S1 a solid choice for those seeking a high-speed ride.Expert Reviews
