I’m trying to find out if the Specialized Como SL 5.0 is compatible with a Redshift seat post. Currently have a Luna Stealth with redshift and it is the difference between extreme pain and no pain at all. Only reason to look at another ebike is for extra gears and maybe a bit more battery, my Stealth has 3 gears and the battery at level 2 of 3 lasts about 5 miles. That, and I really need a lower bar/step through. I have my Luna set up right now very nicely and love it otherwise. Need 45 lbs or less because I have to manhandle it every day into a tiny elevator.
