The stylish sturdy frame of the Fiido X is a turquoise color that looks rather stunning in person. It’s interesting to see the crank mounted at the bottom of the seat post frame and then have the chain lead back to the rear wheel. The magnesium alloy has lovely curves and feels substantial in your hands. The bike looks minimalist, but it does weigh in at 43 pounds so has some heft to it that gives it a quality feel. Cables are only visible on the front handlebars, the battery is integrated into the seat post, the bike folds up securely, and the torque-sensing system offers seamless assistance. If you’re looking for a folding e-bike for getting around town, I highly recommend the Fiido X.
Unboxing and walk around the bike
Unlike other folding e-bikes I have tested, the Fiido X arrived in a long flat box so it was not in the fully folded position. The frame was extended, both wheels were attached, and the front stem was folded down along the right front of the bike. The pedals and fenders (a separate accessory option currently being included for free) required assembly, with the fenders taking me a bit longer than planned due to the small nuts and a bit of awkward hand gymnastics required to secure the fender mounting brackets. The seat was also not in position, since the seat post is also the battery for the bike. However, connecting the battery seat post to the bike doesn’t require cables. You simply slide the battery seat post into the opening in the rear of the frame and then lock the clamp down into place. The opening is designed to make the connection between the battery and the electronics of the bike, which is a rather innovative design that we’ll discuss more below. There are a few elements to unfold to get the bike ready to ride. Unlike the Fiido L3, the Fiido X doesn’t have an integrated stand for the bike when in the folded position, and instead the seat is used as the stand (see the photo below). The steps required to transform the bike from folded to ready to ride are:
Unfold the main frame: Swing the front half of the bike forward and align the main frame. Flip over the metal locking mechanism and snap it into place. To fold the bike, you need to press the release button under the frame.Front stem: Swing up the front stem with handlebar assembly and lock it into place. There is a latch that you extend and then retract to release and then lock the stem into place. The handlebar height can’t be adjusted, but it worked fine in my testing for riders ranging from 5 feet, 4 inches, to 6 feet, 1 inch.Slide the seat post to the preferred height: Lift up on the clamp at the back of the frame to release the seat post and then slide it to your preferred height.Flip down the pedals: The pedals fold in half to make for smaller stowage, so make sure to flip these down and into place before riding.
In order to start riding the bike, you first need to enter the unlock code on the small keypad found under a cover below the tail light. It take a bit of practice to get the process down and if you turn the bike on and off a lot this part of the process may get a bit annoying. The bike requires that you do not deviate from the process or things will not progress. There is a Fiido Riding App that allows you to lock and unlock the bike right from your phone. It is currently in beta form and being tested so it should soon be ready for public use and that makes the bike even a bit more compelling to have a smartphone element associated with it. Review: The Urtopia Carbon E-Bike is a work of art that you can ride First press in on the battery button near the seat so that button glows green. Push and hold the top left button on the keypad until a long beep sounds. Enter the six-digit number code and then press that button again. The small display on the bike should turn on and then you can get on the bike. The small display lets you switch between three levels of assist, control the lights, and switch units. If you want to remove the seat post, then you need to follow this same unlocking process, with the last step being to press the unlock button, which is the bottom left button on the keypad. This system means the battery cannot be removed and the bike cannot be turned on without the security code. It won’t prevent theft, but it might deter it when the thief realizes they can only ride the bike in manual mode.
Performance
Most of the bikes I have tested in the past few years had pedal assist and a throttle. There is no throttle on the Fiido X, but there is a seven-speed Shimano shifter to help you tackle hills. The algorithms provided by Fiido with the torque sensor are fabulous and it has the smoothest assist of any bike I’ve tried yet. You don’t jump off the line, but you can feel the assist kick in subtly to provide an enhanced riding experience. The shifter worked flawlessly to help with hills and it was a pleasure to ride the bike.

The model I tested provided assistance up to 15 mph; the US model is capable of 20 mph. Even if I pedaled on my own faster than this, the speedometer on the display never went above 15 mph, and hopefully Fiido can release an update to show riders their speed even if it exceeds the assist limit.
The hydraulic disc brakes stopped on a dime and were very reliable. The handlebar grips are comfortable, but could use a bit of an ergonomic pad for extended time on the bike. The seat is pretty minimalist, but I am used to riding bikes so it did not bother me at all. You can always replace the saddle if you want more comfort.
The front light is elegantly integrated into the frame and brightly lit up the trails and roads I was riding on. The rear light, positioned above the keypad, was also bright and illuminated the bike well. The tires, wheels, and pedals are all well designed and performed flawlessly.
The battery is rated to provide up to 80.7 miles of assistance. My testing showed the battery would provide about 70 miles on gravel trails and concrete roads, but I am also near the maximum bike weight load. I also tested it without any assist and found it to be a great bike without the battery on, but the lights do not work in this mode.
Bottom line
Folding bikes are not designed for off-road riding and tackling the biggest hills and challenges with suspension, big seats, or extended ride comfort, but they should provide a reliable riding experience around the town while folding up compactly for easy storage and travel. The Fiido X excels in these areas while also looking like a bike twice the price. There’s even a strong magnet system on the left side of the wheels to hold the bike together in a folded position. I am not a light rider at 242 pounds, but the bike remained rock-solid with no flexing of the frame. I even tested it out on gravel trails in Colorado and it remained one of the most stable bikes I have tested to date. The Fiido X is a stunning foldable bike that is available for $1,799. Fiido is currently including fenders ($44 value) and a kickstand ($23 value) for free while also providing a code for $200 off (FX20). If you want a bike to ride around the city that offers a smooth assist experience, a gorgeous design, and a high-quality build, then consider the Fiido X.
Alternatives to consider
If you want an e-bike that you rarely have to charge and one that you rarely have to pedal, then the Fiido L3 is a great option. There are plenty of other folding e-bikes to consider too.
