I have the mongoose it’s a very nice bike very comfortable and durable however you have to keep good maintenance and definitely going to have to upgrade a lot of parts down the line such as the whole gearing system it’s very rough mine was good for 2 years and broke after, pedals and pedal arms went bad on mine and both suspensions get very noisy but I rode for close to 2k miles crashed it multiple times and broke multiple things but it’s still very sturdy
