what is a 1991 diamondback topanga worth…. like new … 4 plus on a 1 to 5 scale ?

5 Answers

  1. Yep, sorry. Although the Topanga was not a bad bike, the technology has progressed so far since then that your bike is almost obsolete.

    It is not by any means collectible although it may pique the interest of someone that wants a beater bike.

    Generally, you can take the original cost of the bike and subtract 5% for each year of age, then take an additional deduction for condition. If the Topanga sold for $500 new and is 17 years old, the MAXIMUM value it would have would be about $75.00.

  2. Not very much. Its hardly an antique, and wasn’t anything special back in the day, so no collector value. Current design MTB’s are far superior in every way, so its inherent value as a rideable bike is less than even a low end new machine.

    About the same as asking what a 1991 Chevy Cavalier is worth. As transportation it has some value, but that’s all.

  3. Like most have said it has little special value. Any bike in very good shape will bring 50 – 75 bucks.

  4. Its an entry level big D back in those days….though I suggest you check out BETTER bikes by IRON HORSE, SEVEN, SARACEN, KONA, GIANT or FELT. ( go for the new breed cuz the components have stronger material) Anyway, its all found on EBAY (www.ebay.com —-SPORTING GOODS, click Mountain bikes & frames —BINGO!). There are bargains for the budget novice to the wacko pro rider so select with real deals,kapeesh?)

  5. $50 at most garage sales.
