um. ok. youre right.
Wouldn't all it would need is the shifter hub manufactured with a left hand free wheel? I'm using the Nuvinci and it seems that it would work if the ratchet and pawls were just reversed. Don't know if their would be enough demand to have the design change implemented, but it sure would be nice to eliminate all that extra drive train weight and resistance.Um. No. LHS drive hubs all take 14mm axles, which are 14mm for the strength to take stuntpegs... BMX.
Only reason for LHS drive is doing grinds on ramps if you prefer to rotate ccw like most right footed and right handed people do.
Larger than 20" wheels make grinds very difficult even if you chose to use 14mm axles and put stuntpegs on.
I think IIRC someone already asked the makers of the Nuvinci to make a mirror version and was told it just isn't going to happen. It would be great though if it was to happen.Wouldn't all it would need is the shifter hub manufactured with a left hand free wheel?

I'm with you on the nuvinci, the design is particularly simplified when it comes to power transfer from the sprocket to the wheel, it's a reversible design in that area. If you somehow reversed the paws it would almost definitely work, I also would think that locking the freewheel up could do it if you had a freewheel before that cog, like how the bullet train runs a one way clutch just before the drive gear, then it wouldn't need any real modification.Wouldn't all it would need is the shifter hub manufactured with a left hand free wheel?

Then once you stop to think about it not only is the reduction a really big issue but you no longer have a motor assisted bike. I mean what are the pedals doing. I'm beginning to like my j shaft more be the minute.Not to mention reduction. You need to get the right size sprocket with the right type of mount to fit the hub.
Idk what the Nuvinci uses for sprocket mount, but I wouldn't be keen to experiment with trying to reverse the freewheel if it's built in, lol... those are expensive hubs.
If you are daring you can do the flintstones thing and run around to start it should you decide to omit the freewheel you could shift with the right hand and use a thumb throttle... Using brakes might be hard...Then once you stop to think about it not only is the reduction a really big issue but you no longer have a motor assisted bike. I mean what are the pedals doing.
