I did alot of research before buying my eBike. I needed something light weight and portable/foldable so that I could throw it in the back of my mid-size SUV and take with me. I'm a big guy, so I need a powerful motor. I thought I would need a throttle, but in reality, throttles make you lazy, and you tend to pedal less. This bike does not have a throttle, but it has a torque sensor, and it almost reads your mind: as you pedal faster, it gives you more electric power. Truly a thrill to ride, unless you want a more "scooter" experience. The fit and finishes are all high quality, though my unit has a tiny flaked off edge of yellow on the carbon fiber frame where it folds. I think this will be easily masked with some automotive touch up paint. The cables are for the most part hidden in the carbon frame. The fold up sequence is simple and intuitive and fast. Two magnets on the front and back wheels help keep the bike folded, as the hinge only locks in the riding position, not the folded position. The integrated front and back lights are well done, but when you add a back cargo rack and basket, the red light on the back of the frame is obscured. Urtopia: on the next version, add a red light on the back of the upper seat post, for better visibility. The ride is stiff (no shocks) but extremely agile with the 18" wheels: turns on a dime. The seatpost has cm markings so you can remember where your sweet spot is, but in the next version, I would add those markings to the front of the seat post where they would be more visible than current position in the back of the seat post. What else should they offer? A cell phone holder for the front handlebar would be nice. Also, attachment points for a water bottle cage, perhaps on the handlebar upright?
