Which company did you write to?
Lectric have the details on their webpage:
Shop our XP™ Electric Trike, the industry's first foldable and fully-assembled 3-wheel electric tricycle accommodating a wide range of abilities for anyone to enjoy.
Wrote to Lectric yesterday......they told me that they haven't seen the trike yet and couldn't say what the rider height and weight limits are yet. Here's their response....
At this time, we have very limited information on the trike. It will be launching officially on February 7. Between now and then we would like to invite you to check our website for updated and information on the trike. Also, please be sure to subscribe to emails so you are in the know on information about the trike as it is released.
I hope this information helps. If you have any further questions as we get closer to our launch date, please let us know. We will be happy to help.
In a second correspondance.....they said this.....
The trike is still going through testing processes, and once it completes all the phases of testing, we will publish all of the necessary specs, including payload and dimensions, etc. Please keep an eye on our website for updates between now and our preorder date, February 7.
Thank you for reaching out. If you have any further questions, please let us know. We will be happy to help
