This electric bike truly exceeded my expectations. Its sleek design looks even better in person—every time I ride, it draws attention and compliments from people passing by. Whether cruising through the neighborhood or parked for a moment, someone always stops to say, “Nice bike!” Equipped with a powerful 1200W motor, it climbs hills with ease and delivers smooth, consistent performance across different terrains. The 48V 18.2AH battery offers impressive range and reliability, making every trip enjoyable and worry-free. Assembly was quick and simple, with all parts securely packed and protected during delivery. The bike feels solid, all adjustments are easy to make, and the ride is comfortable.
