I probably should have given myself and all of you, more time to respond. I needed to make a decision without the benefit of your feedback. I didn't ignore your advice...I simply didn't have it in time to make the decision.
Based on pictures...my son really liked the color theme of the Haro Supra. It's a bright yellow with red trim. Has a certain "catsup and mustard" appeal to it I suppose.
I went and had a look at both the Supra and Fatboy. The seller had worked at a bike shop for a number of years and took excellent car of both bikes. The original paint was pristine, the tires were newer, everything spun easily and quietly.
I knew it was on heavy side, but so long as it's durable, the weight didn't bother me much.
I had it looked at my my local bike shop mechanic and he verified what I already knew. The bike was maintained extremely well and is, with the yellow / red colors...kinda eye-catching.
Oh...and I got the bike for $100. Probably not a steal...one could probably spend $100 in worse ways.
Thanks anyway for the advice. Next time I'll make sure to give you guys a little more time.
