The execution of the Carbon Fold ST is genuinely impressive. You can find faster bikes or more versatile ones, but for what this bike is trying to be, the end result is a great ride.
The frame is made from Toray carbon fiber, which is both very stiff and impressively light. Flex is minimal for a step-thru folding design, and the bike handles confidently. Urtopia also nailed the geometry of the large folding stem, angling it back toward the rider to allow a natural bend in the elbows. Some folders force a more upright, perpendicular position that stretches the reach and makes handling feel twitchy. That’s not the case here. The narrow handlebars and 20-inch wheels feel agile instead, resulting in responsive, fun handling.
The frame looks sharp as well. It has a 14-inch step-over height in the frame itself (closer to 16.5 inches in practice due to the large chainring) and comes in blue or white. The overall design is sleek, and the folding feature works smoothly, taking a minute or less once you get the hang of it. I also appreciate the internal sleeve that protects cables from getting pinched when the bike is folded.
The small details really add up. The seatpost collar and folding stem use wide, easy-to-grab latches that don’t dig into your fingers. The handlebar raises and rotates into position easily, and overall, the bike is full of thoughtful touches that contribute to a smoother, more refined experience.
Is it perfect? No. The charging port under the saddle isn’t the most convenient access I’ve used, and I still prefer designs that plug directly into the back of the seatpost battery. That said, it’s more of a mild inconvenience than a true annoyance.
The included lighting and fenders are welcome additions, and the display is easy to see and interact with without feeling intrusive. Touch points are mostly solid. The grips use a standard ergonomic shape, and the saddle strikes a nice balance between sporty and plush. It even includes a hidden spot underneath for an AirTag if you want added tracking.
There are two accessories that don’t come standard but can be purchased separately: a throttle and a rear rack. I’d recommend the throttle and wish it were included out of the box. The rack may make sense for some riders, but it’s worth noting that the bike’s 220-pound payload capacity is lower than average, so a full-size rider plus gear could approach the limit. The rack’s placement can also obstruct the taillight when loaded, which is something to keep in mind.
Overall, I’m impressed with how this bike feels. The responsive motor, lightweight carbon frame, and narrow tires come together for a pedal experience that’s quicker and more engaging than it first appears—and when the ride’s over, it’s genuinely easy to fold up and put away.
