Hi Jim,

first, I'm no Spice expert; but is it possible, that you forgot to
remove V_V1 from the model, so that one could control the KM/H with an
external voltage source via node KMPH?

Yep, Thanks, Nice catch.

Yep. Others see below for the correction. I had left in the test
source, which must be removed for normal use...

Obviously a fair-weather cyclist - no mudguards. The Lycra brigade go
all out for lightness, and in consequence the Lycra develops a broad
stripe of dirty brown whenever it rains.

And the derailleur looks more Japanese than Italian. My local bike has
Campagnolo gear. The Sydney bike is newer and still has the Shimano
gear that it came with. I may trade up when it wears out (though I'll
probably wear out first).

I'm just the opposite. My body won't let me sleep more than about 5-6
hours.

When I was a student I once slept from the Wednesday evening before
Thanksgiving until the afternoon of the following Sunday Wink

I was out for five days once, with the Flu. I lost over 20 pounds and
I couldn't even stand up, when I woke up. :(
