[python] Re: AW: Re: Python for lots of load // No Mountain Goat?

The problem with multi-rider cargo vehicle is the space and time the extra rider(s) would cost, unless the cargo is heavier than one rider can handle.  Electric motor assist is gaining popularity here.

Couple of weeks ago, I got leg cramp going up a train overpass, after ~3 hrs riding the futon trike, ~200 lbs with cargo to and back from work.  I was surprised that I could limp my way up hill, while loosened up the legs for another go back home.  The next overpass, I had no hesitation getting off the trike and pulling it up hill (no ego damage).  It seems that pedaling cargo uphill costs a lot more energy than pulling.

So do we have a new requirement for python walk-ability, with full load going uphill?

Hi,
if the seat is to close to the contact point of the front tyre on the street the python might tend to flop over the front weel going downhill. Specialy if the seat is not very low. This might be an unpleased expirience.

A long weelbase will help but will also make the python less nimble.
A reclined position will help, but will destroy, most what you gained by moving the seat forward.

Maybe its because it is a python, not a Mountain Goat?

I guess it is what you pay for the low position and easy drive train.

PS Maybe Mountain Goat should be the name for a three in a row, all wheel drive recumbent bike  project?

Hi,

I guess if the driver is very close to the front wheel contact point, this could make a difference. A small front wheel would help and also a slightly elevated position to get even closer/further forward to the contact point. However, unless its a trike design, changes like this would alter the behaviour of a python substancially.

greetings,
