Hi, I'm new here.
I weighed 380 lbs this time last year, and I'm down to 325 from walking walking walking.
My knees started to hurt, someone suggested biking. Wasn't sure it'd work at my weight, so I was suggested a fuji crosstown 4.0 as a good beginner bike and was told it would support my weight, I'd just need to ride at higher pressures.
Got the bike. First thing that didn't work was the spring loaded seat post as it bottomed out. It was exchanged with a nice solid post and now the seat is fine.
3rd time I rode, I was going down a flat road - suddenly - bulge wobble and BAMMMMM! the back tire blew. Upon inspection the tube came apart at seam. They replaced - said it shouldn't happen again. Rode home (2 miles) - nearly home - front tire - wobble - I stopped instantly this time - and about the time I stopped - BAMMMMMM! like a gun shot. Same deal - tube came apart at seams.
So given my weight - is this doable? Are there some 'special tubes' I can get? Thanks for honest and frank advice. I suppose I'm stuck with the bike, so try to work with me on what I have, and please realize I can't drop a 'ton' of money.
Thanks, I hate for this to be the first post - but I hope someone can help recommend something to me.
