It's a old GT Timberline what I bought for approximately 90 USD and it has this problem when I pedal backwards or stop pedaling.
When I pedal forward, it goes relatively well and has no problem changing gears.
I want to see if it's something I can fix at home before taking it to a bike shop.
Help!, I just bought it and it has this problem
