Hello, so im converting a hardtail mountain bike to a 3000w 72v e bike. For the upgrades on the bike itself, what would ypu reccomend. I am trying to save some money on this by the way. I assume i should upgrade the fork (any reccomendations on what fork?) And then the brakes... im thinking 4 piston hydraulic brakes? (Any reccomendations on what brand?) And what rotor size? Thanks.
