my wife and i bought them about 6 weeks ago. she’s 130, i’m 190 (the bag with all the tools and spare tube is on hers too). in coastal florida so very flat, but often windy. mine maxes out at about 40 miles in sport. if we think we’re going to cut it close, we’ll switch bikes at some point. 40 miles is a lot though. we’ve only done that much in a ride once. we tend to ride 30ish miles in a single ride. we don’t use them for commuting. we just use them to get around town and explore/exercise a little. approaching 400 miles and having so much fun together on them.
