its the standard here to post pictures of the other side of your bike so we can see the crank, and deraileurs. also some close ups of the shifters/brakes may help. from what I can tell it is a low end/ comfort oriented cruiser, probably not your best choice for long rides or fast morning commutes. But as far as just pedaling around the park for fun and sightseeing its a winner. it looks to have a steel frame and fork, mid 80's (?) multiple gears on the back which will help with small hills. It appears to be in decent shape minus the flat tires most likely no more than $200 brand new from a department store??
