plus size cycling..where do I start?

[nuliajuk]

So I bought a used bike, a centurion, just to try out cycling. I've read other blogs that talked about getting stronger tires to support the extra weight. What is absolutely essential to upgrade/maintain on the bike just for a beginner cyclist? I'd appreciate the help and support!

I don't think it's the tires, but the wheels (rims and spokes). Sometimes heavier people need to have their wheels re-trued more often, but this is something you can be taught to do at a bike maintenance course. Larger diameter tires can protect the wheels with a bigger air cushion, and keep them inflated to the higher end of the recommended range. Unweight the back wheel by getting out of the saddle over level crossings and frost cracks or potholes that you can't avoid going through.
Really, it's unlikely that the wheel is going to collapse, just go out of true more often, so just ride and don't worry. The Centurian dates from the 90s, when wheels had at least 32 and more often 36 spokes, so you should be fine.

TE is a great place for Plus size shorts and jerseys. Other than that just get out and enjoy it. I started out at 247 and now I am down to 210. I have always ridden a bike with factory rims and never had a problem because of my weight. Just make sure the bike is in good conditioned and tuned up to avoid basic shifting issues and such. Then just get out there and have fun. My first ride was 2.5 miles and I thought I was going to die. I am now working towards my first metric century, so if I can do it you can do it. Have fun.

Thanks so much for all the votes of confidence! I can't wait to get out there. I do need to hit the local bike shop and make sure everything is a go- the tires are flat . I'll also be sure to get a helmet and some gloves there and glasses. I got a floor pump coming to me! And I'm pretty excited to get some TE gear as I work my way up to longer rides. I'll keep you posted!

Thanks for all the advice! I rode some this weekend and I loved it! I definitely need to get some of those shorts though or the skort. Eventually, maybe a new saddle?
Thanks again for the encouragement- ya'll are great!
