Hey guys, I'm new here and have recently started riding seriously. I started in at about 290 lbs have lost about 10 lbs so far. I've been riding 10-12 miles a day and the bike I am riding now is an old Walmart mountain bike called a Quassar. My LBS says that there is a bunch of stuff wrong with the bike and that it wouldn't be worth investing a bunch of money in it. When I get enough money saved up I would like to buy a new/used hybrid or road bike. I don't know which type of bike would be better for me at my weight though. I only have about 4 gears available to me on this bike and its a 21-speed. I need something that I can get into those gears that will make steeper hills more possible to climb. The bike I currently own is very heavy and I feel this slows me down even more. So if anyone has any suggestions about the type of bike or if you could link me to good brands of bike that would be great. Also I wont have a butt ton of money to spend on a bicycle lol.
