(...) You mean the thinnest tech gear which is about 1/2 a brick wide? :) (the thin bevel gear, that is-- too bad they don't make 1/2 brick wide chain!) (...) Perhaps you could build a FUNCTIONAL one that wasn't "accurate" with a transmission and (...) (24 years ago, 1-Sep-00, to lugnet.loc.au)

I have a solution for the coasting problem. This method allows the wheel to move without the pedals moving and even allows the wheels to move forward if the pedals are moving backwards. The pedals drive one axle of a differential. The other axle of (...) (24 years ago, 2-Sep-00, to lugnet.technic)

Very nice solution. But we're building a bicycle, not a car!! Differentials are ungodly bulky things, but for technical accuracy, they might do the trick!! Have to upgrade the elephant cyclist to a hippo or whale now! ;-) Cheers ... Geoffrey Hyde (...) (24 years ago, 2-Sep-00, to lugnet.technic)

(...) Well, I have to agree-- the differential is an elegant solution, but a little more complex than necessary... a single ratchet does the trick by itself without really needing the differential. I'd say that there's also the size issue too, but (...) (24 years ago, 2-Sep-00, to lugnet.technic)
