I got a RadRunner 1. Made my own passenger hauler just to test the waters. It did good with 2 adults on it but now I have my old SHAD trunk on it. Will do 35-40 miles max on a full charge. Tops out at 20mph. Battery takes around 5 hours to charge. I have over 2000 trouble free miles on my 'Runner. Ride in all weather and it does great. Best deal in ebikes IMHO.
