Unfortunately, this experience has been one of my worst and only continues. I ordered and fully paid for a Juntos foldable e-Bike in early March this year (so we could use it this Spring and Summer). It is still unsafe and ComfyGo has not addressed the significant safety issues or allowed me to return the bike. 1) I had to wait several months to get both batteries I ordered as they were on "back-order". Even then I had to follow up with the regularly in order to actually get them. Once they arrived and I assembled the e-Bike, the instructions and pictures were very unclear and inconsistent, although not too difficult. The front brake rotor was badly bent, the headlight and brake lights don't work. They have sent me some new parts to try and fix, however, they don't offer to help and once they get you off the phone they seem to act like they are done. Getting them on the phone or to answer and email is also not easy. The bike is actually quite nice, however it is unsafe to ride in its current condition and they don't seem to be interested enough in trying to fix it. I'm hoping this post will help me to drive some action.
