There's been a lot of discussion about the use of IGH type gearboxes, recently.
I thought I'd throw this out, to get some feedback:
-It's a retro-direct gearbox with a ratio of 2:1.
-Second gear is direct drive (minimal additional losses).
-It has integral freewheeling, as do most retro-direct type drives.
-In first gear only, it has the ability to switch between freewheeling mode and regen. mode
-Gear change is by reversal of motor direction (no need to ease off the power...).
-Maximum input torque is 40 Nm.
-Weight is about 1 kg (as are most 3 speed IGHs).
-Diameter 100mm. Length 72mm (not incl. shafts).
-To make it clear - this is not a gearbox for combined motor/pedal drive, it's for motor only.
