I work with a chap who’s been dithering for months whether to buy the 120mm bike
They are both great value, but you need to be 100% sure of what you want in a bike. A 150mm bike is a big old machine to drag around, day in, day out
How savage are your local trails?
I run an all mountain bike with 160mm front, 140mm rear and it can a struggle for normal rides on local tame trails. I also run a hardtail, which i probably use for 80% of my local riding
The colours on the AM look a look nicer mind
The only thing i’d say about the 120mm bike is that it hasn’t got a bolt through front axle – it’ll only be £100 to upgrade after the purchase, but they make such a difference
However, my primary consideration would be what you’d be using it for, because 150mm of travel on your day to day bike is a lot
Cheers
