onewheels suffer from a problem known as nosediving in which the board shuts off when it can't supply enough power to support the rider, as the board is self balancing this is a problem intrinsic to the board's form factor. The board works in a similar fashion to balancing something like an umbrella on your hand, as the rider leans forward it creates an imbalance that requires the board to accelerate in order to keep the rider upright. The only possible safety feature to prevent nosedives is to inform the rider that they're approaching the board's limits, this is done with "pushback" where the board elevates the nose making the rider uncomfortable, signaling that they should slow down. Newer boards are more aggressive with pushback, it's definitely a balancing act giving the user the most power from their board while also preventing them from nosediving, future motion faced significant backlash when their new flagship board implemented extremely strong pushback at a speed lower than a prior discontinued model
