Fiido X observations and questions after 55 km ride

Hi everyone! I got the Fiido X during the Black Friday sale and was initially impressed with how compact and neat it is. Although my gear shifter didn’t work, support arranged for a replacement, which should arrive tomorrow.Yesterday, I took it on a longer 55 km ride (despite the broken shifter) and made some observations:

  • The battery died after ~45 km on Eco mode. It was around 0°C—does the cold really cut capacity by over 50%?
  • There's noticeable drag downhill, even under 25 km/h, so I had to keep pedaling.
  • Pedaling without the battery is very tough.
  • I felt more fatigued compared to riding a regular bike—my hips hurt, possibly because the Fiido doesn’t roll freely due to the drag, meaning constant pedaling.
  • My seat slid down twice unexpectedly, so I had to stop and readjust.

Have others experienced similar issues? Is this normal? Also a couple question:
- where do you put your lock while biking?
- how do you roll it with you when folded? Do you roll it forward in front of you pushing the seat, or do you drag it behind you holding onto the flap that otherwise connects the two halves of the bike?
