First time cyclist, broke

See title. I do not have much leeway for spending, but I want to get into cycling after trying it out. I live in a very mountainous area with lots of elevation. I'm pretty mechanically inclined but find fixing my vehicles emotionally exhausting, so reliability and durability are important to me. Realistically though I can't drop more than 100-150 on just the bike until winter, which feels silly. Do I just give up on cycling this year?
