I'm not an RF expert, but rebroadcasting BT seems like it would create more interference. The rebroadcasting is done because the goal was to get the data into a proprietary piece of software that expects data to come in over Bluetooth. And rebroadcasting will actually be just fine on the air medium because right after receiving is exactly the time when the bike won't send another message. The RPi is complete overkill of course, a tiny $3 nRF52 module could do that job just fine.
