I'm 4'9 and 80lb female adult. I have been searching full suspension e mountain bike. But I have hard time finding one. The Trek Powerfly FS 4 is supposed to fit, but when I tried it, the standover was too high for me although the ride was comfortable. I also tried Liv intrigue E+2. Again, the ride was good, but standover is bit high. i.e I had to stand on my toes and I had hard time getting out, which would be even harder doing so on the trail. I wonder if it's possible to convert a kid full suspension mountain bike to e bike? I'm a beginner and want to try single track easy trails as well as ride on gravel bike trails. I don't have a kid bike yet. Just want to gather some ideas and wonder if it's possible. Thanks!
