I installed the replacement display within 2 hours. I had to: remove the cable wrap, separate the S900 cable from the others, snip several zip ties, remove the old cable, feed the new cable through the frame into the control box, connect the pins, re-wrap the joints with electrical tape, install new zip ties, close the control box, re-wrap the cables, install and configure the new S900. I wanted it to be secure and appear like new so I took the time to do it correctly. I can see that the Ecotric engineers identified the need for a quick release joint near the S900 so future replacements should be a simple 15 minutes task. Good job, Ecotric! Possibly, the newer ebikes are sold with that quick release joint. My Seagull is over 3 years old and didn't have it. I also see that the designers put enough cable tucked inside the frame to accommodate installing a stem riser or alternative handlebars. Again, good job, Ecotric!
