The Ultra Flex stands out because it’s all about delivering a thrilling, versatile ride. It features a full sport-tunable suspension system, so it smooths out bumps and handles jumps with ease—perfect for all kinds of terrain. The frame is made from patented 4130 Chromoly steel, which is lightweight, super strong, and gives you a great road feel.
You get a massive 25Ah battery, so you can expect over 30 miles of range on throttle only, and up to 45+ miles with pedal assist. The seat height is 33.5", making it ideal for taller riders (5'8" to 6'5"), but it’s still comfortable for a wide range of people. Plus, the STICKY SWEET tires have an aramid lining to help prevent punctures. It’s a high-comfort, high-performance e-bike built for adventure.
