This is great then. I would prefer SPD, but if it's similar maybe for the better. Only issue would arrise is if a wellgo part snaps after long use and I need a replacement part that isn't carried by a local bike store. Not to say they are low quality, but never heard of them and no experience with their product.
I would get them, in that case. Going to research the brand and hopefully there is a SPD type with an interchangeable flat petal I can switch out for commuting. It would make sense they would. Usually when I make a purchase of this nature I select three options to choose. Whether it be a SPD or similar it makes more sense with SPD with familiarity, but not necessarily as a switch out availability would be fantastic from the flats to a SPD-like option.
