Need help with determining a fair price of this bike

Saw a local ad for a bike...the right size for my teenage son.

Here are the specs:
21-speed road racing bike with 17" lightweight aluminum 7005 frame
Shimano REVO gear shift system and caliper brakes put you in control
Vitesse V-profile 24" aluminum wheels with 700c Kenda tires
Shimano TZ30 derailleurs make climbing hills easy
Gear Speeds: 21
Bicycle Frame Material: Aluminum
Seat Features: Adjustable Seat Height
Brake System: Caliper
Rear Brake System: Caliper
Derailleur Manufacturer/Type: Shimano TZ40
Bicycle Chain Material: Alloy
Wheel Features: Pneumatic Tires
Rim Material: Metal Alloy
Front Wheel Height: 24"
Rear Wheel Height: 24.0 "
Tire Type: 700c
Tire Width: 2"

Owner says it's a "custom" bike bought by his parent but no idea of the brand, but he is a cyclist. Said his parent paid $450 for it gave it to him over the holidays but now he sells it for $350. I looked up the frame and components and it seems to be similar to a GMC Denali which you can get a new one for $179-$250...

Here are two pics.





Any thoughts as to a fair price for this bike? I don't know much about bicycles but don't want to pay $350 for something that's $159.

Thanks.

The only thing that is 'custom' about the bike is the name on the downtube. That's been changed. It's a GMC Denali. Used, I'd put the price at $75 if I were being generous. You can do a whole lot better in the used market for $350 and you could even do better in the new market for only a little more.

That's what I thought.

When he said he's a "cyclist" and didn't know what bike it was but it's a "CUSTOM" bike from his parent I got a bit suspicious.

I can get a brand new GMC Denali for $149!

Certainly not worth $350. Not really even worth looking at, IMHO, and I do not have a predjudice against X-mart bikes.

I am confused about his description of the 24" wheels that fit 700C tires. Run, don't walk, away from this seller.

There is also a 24" wheel version of the GMC Denali, with 24 X 1-3/8 wheels and tires, which are much more likely to be close to 24" if you measure the diameter of the wheel w/tire.

No matter, the general consensus here is that the bike is a piece o' carp, so hopefully the OP puts that one in the back of his mind and keeps looking for somethign decent.

Well we are talking about a GMC Denali bicycle here. It's only an approximation of a bicycle so what's half an inch, more or less? Now the front wheel in the same ad listed as 24" and it also contains this nugget

• Vitesse V-profile 24" aluminum wheels with 700c Kenda tires
I figure they just rounded the value.

There are any number of reasons for the confusion. I also initially assumed that it was referring to a rough estimate of the rim's OD, but then I was looking online for a Denali with the same paint job to confirm your assertion that that it is a Denali with a 'customized' downtube sticker, and I found one with identical paint that was a 24" wheel model. And it is hard to tell from the photos, but it would not surprise me if those were 24" wheels.

Since the ad claims the wheels are both 24" and 700C, and both wheel sizes are available on that model of bike, I don't think it is safe to assume one way or another. Perhaps he thinks '700C' refers to all tires intended for road use, or maybe he got the specs from a website and was mistakenly looking at the 700C version. The only thing we can assume is that the seller doesn't know his arse from a hole in the ground. And that that bike is crap.

The page I found with the 24" wheel Denali (or is it Denial?) says 24 X 1-3/8, which the late great SB says has a BSD of either 540 or 547 (21.26" or 21.54") - add 1-3/8 X 2 (approximate height of the tire times 2) and you get 24.01" or 24.29".

I think it is necessary to repeat that, no matter what size wheels it has, the bike the OP was asking about is crap and should not be purchased for more than $75... preferably not at all.

If the 17" denali was the 'right size'
then this one looks too big

I wouldn't crow too much. Look at the ad again. Are you sure? It says a 17" frame. That's not a frame size that I've ever seen for a small bike...most of them with a true 24" wheel have frames in the 12 to 14" range. The ad also says that it's has a standover height of 26" which is more in line with a 17" road frame with 700C wheels. That's a mighty tall inseam for a little kid. The ad copy also says this

Quote:
Vitesse V-profile 24" aluminum wheels with 700c Kenda tires
# Front Wheel Height: 24"
# Rear Wheel Height: 24.0 "
# Tire Type: 700c
Granted the ad copy is all screwed up but which is it? 24" wheels with an ISO 507 rim or a 700c wheel with ISO 622?

There is also this little nugget from miamicuse

Which begs the question: Is the owner 14 or just short?

Cock-a-doodle-doo!

I am quite certain now that the OP's CL ad is for a 24" wheel kids bike. The Target (pronounced 'Tar-jay) ad is for a 'boys' Denali, which is listed on the Kent website as having 24 X 1-3/8" wheels. Also, take a close look at the picture and the size of the wheels compared to the frame and saddle certainly make them look smaller than normal - kind of hard to tell due to the perspective of the photo, but I am convinced that all the evidence points to this being a kid's bike.

When I met my wife (who is short) she had a Supercycle (or somthing similar) with 24 X 2.0" wheels and an 16" seattube. It may not be the dimensions of a bike you or I would design, but bikes like that do exist.

Edit: The specs listed on the Target site are messed up for a few of the other bikes... there is one that claims to have an aluminum alloy chain.

Cannondale might be a bit overpriced, but is orders of magnitude better than the other one.
