in about 10 seconds a side if the land rower had the shimano or similar multi speed hubs implemented the rider would just change gears by clicking the gear selection knob 194 as shown in fig1 moving the gear selection knob 194 would then change gears on either the wheel hub not shown or the handle hub also not shown the gear selection knob is attached to another handle 192 that just above the rider 39 s hand path so that it is easy to change gears as the rider completes a rotation of the crank handle 111 the preferred embodiment for physically challenged riders would omit the footrest brakes and have brake locks 152 as shown in fig1 the brake locks 152 would lock the drive wheels 72 while the rider gets into the land rower in addition the gears and brakes could be implemented similarly to the handles and brakes of fig8 however the shimano nexxus hub is preferred for the brakes since the rider only need to reverse direction on the crank handle to brake in sum the land rower is intuitive to ride the action of cranking the handles is like rowing its low center of gravity makes it inherently stable at any speed including at rest the design propulsion method and pivoting backrest make it comfortable and fin to ride the main skill for the rider to.
