I'd stick with the Schwinn but I know the new bike fever is hard to beat😁. I'm the heaviest I ever was at 157kg. About 350lbs. I have an old Raleigh 531c steel that never gives out and an aluminium Brodie Romax that seems to be holding up well enough. I just have to use them more! Will you get a warranty with the new bike? Make sure to check that out. Rocky mountain used to be amazing bikes but now I think they're regular chinesium.
