The Motobecane has a better spec, but the frame looks like a cheap catalogue frame (ie not designed by the people selling it, they simply slap a badge on something cheap designed and produced out east). I’ve seen a few Motobecane bikes come into my shop for repair and they’re not good quality.
It’s better to spend the money on something with a better frame from a reputable company in my opinion. Marin and Giant have large dealer networks with good support in case anything goes wrong. The frames are also likely better quality and better handling since the brands selling the bike in this case design the frames and geometry themselves. Since the frame is one of the last things you’ll upgrade, if ever, it’s worth spending the money for a good one. To me the Marin looks like the best bike of the bunch by far.
