Yeah good question… Thanks!
Bit more blurb I just thought of below….
Freewheels like a normal hub (sounds like a hope hub!)
LinkDrive uses a specific patented geometry of links to connect the pedals to cranks on the rear hub. The geometry ensures a smooth, forward biased action, where the downward stroke of one pedal starts before the lowest point of the other. This, combined with the near to vertical travel of the pedals maintains torque production for the complete cycle – great for tough climbs on an MTB and makes the most of the elegant simplicity of a single speed. Pedals are placed beneath the rider’s centre of gravity when in the saddle for increased pedal force minimising tiring out of the saddle pedalling.
Powerful pedalling action Great for toe clips /SPDs or flats Minimal maintenance with all joints, bearings and gears sealed No need for cycle clips (or tucking your trousers in your socks!) Road bikes, Folding bikes, MTB hard tail and full suspension, single speed and multi speed hubs in development.
