Hello there, The Bike Ark Yolo gets a Shimano Tourney 21-Speed Gear setup and mechanical disc brakes. It comes with an alloy frame. The Montra Trance Pro also gets a Shimano Tourney 21-Speed Gear setup. The only major difference between the two is the price and performance. The Montra Trance Pro costs more and is a much more premium product than the Bike Ark Yolo. In terms of build quality, the Montra stands a class apart when compared to the Bike Ark Pro.
