That hit me like a brick as well but right after they showed it they said it was only on the prototype and the production bike would have a thru axle, so I sat back down again
Honestly I think the Pinion is still the awesome sauce. there is a Bullitt variant in Germany where the company sells a modified frame that houses a Pinion gearbox, and then they put in a nice big DD hub motor. So yeah sure you lose the gear advantage but you don't care because the hub motor is big enough to do the job. And for me I'd put a front motor on too so at that point the pedaling is about exercise only and I'd be dialing the motor power back accordingly (until the time when I decide not to).
Agree completely on being ready for prime time. This is not the first one of these I have seen but right now they are only on stupidly expensive oem EU bikes that haven't quite gotten the whole concept right yet. Definitely this is the future of mid drives though.
Why would a mid drive need a transmission? Your gears on your bike is the manual transmission. Plus you can change out the cassette to match your driving area. Live in hills all around , increase the rear cassette ring size. Live on mostly flat terrain get smaller cogs. Or have one cog with all sizes. At some point these are just e-motorcycles disguised as bicycles.
Because if done right it totally eliminates the drivetrain alignment issues that a mid drive can visit on a chain. Right now I have a bike whose stays are so short I cannot get to the smallest or largest cogs (11-48T) under heavy load without the chain jumping, despite the fact chainline is dead straight back on the middle cog. The performance-oriented geometry of the bike just will not let a full 10s system work (do it on a cheap ass Chinese frame with long stays and results would improve, but the frame geometry would be Wal Mart quality). I am by no means the only person who has experienced the reality of chain line problems. The common practice of re-ordering cogs comes to mind.
Yeah sure I can do a belt and an IGH but there are torque and equipment issues to contend with.
Take it to the next level and combine a front transmission with a low-range derailleur and rear cluster and now you've got a 21st century touring cycle.
