The trike can fold. I have not tried yet. The motor mount may fall ahead of the cross-members, but I suspect instead I will need to remove the motor to fold.That Magnum can fold for transport I think?
If you look at the pictures, you can see that the motor is not in the rear wheel - it's behind the seat. There is more detail about the perceived and expected advantages in my reply above.How is this different from a normal rear geared hub?
The pictures at the beginning of the post show the right side. The only change from then is that the idler is now a silvery wheel (a sloppy temporary build to test the idea and to be replaced by a more robust implementation soon). Otherwise the chain on the right comes from the front chainring (an Efneo 3 speed planetary hub) through the stock tubes and the one extra silvery idler (to bend the chainline up to the motor/cassette). The motor freehub provides the freewheeling on the chain so that the motor does not drive the pedals.Can you do regen braking? I am assuming the right side chain is freewheeled and the belt drives the motor continuously?
