Jueshuai 48V 500W Electric Bike s900 26" 48V 12AH
More or less the same bikes the NYC delivery guys ride. We bought one and it has been really good. I changed out the stem and handle bars for a more relaxed posture than the flat bar the bike came with. Its marketed as a mtn bike but there is not much mtn in this bike. It is fine on dirt/grass/mud/wet roads.
