Just like some used beater Corolla with 300000kms for $1000, I promise you will be spending a lot more sooner than later.
If it were me, I'd skip $20 lunches and $5 coffees for a good new bike from a LBS (Local Bike Shop) recommended by locals.
You know not all young people are the same right? Thanks for your reply, but if it's just to be condescending, please try not to make a bunch of assumptions.
I have an 07 Honda Accord with 210,000km on it. I understand the additional maintenance costs, however, there is still an upfront cost. You pay a lot more for the maintenance of a Ferrari anyways. And I spend $4 a month on coffee and $250 a month on food(about $3/meal).
The cheapest bikes sold at my LBS are ~$650. Hence, I'm looking for used.
Don't have a Costco membership and even their cheapest bike is $500.
Please let me know if you have any comments on the bikes I mentioned above.
