Hi,

I have no idea what a well funded fact is. Average speeds
according to the two computers is, on the folder is 10mph,
13mph on the road bike and for my bike riding habits a fact.

I can't go much above 18mph @ 100 rpm on the 66 gear inch folder.
I can do 27mph @ 100 rpm on the 100 gear inch road bike going
down a mild hill or with a strong tailwind or a bit of both.

I can ride on the road bike at speeds that would kill me on the
folder, e.g. ~ 21mph on the flat no wind, on the folder ~ 16mph.

My folder routes are very flat, wind is the main issue. Road bike
bike routes are much more rolling with a lot off short hills and
longer minor hills. Riding a 20 mile road bike route on the folder
really does feel about as hard as doing a 35 mile route on the
road bike, and I'm not interested in doing 35 miles on the folder.

I don't want to do long distances on the folder, but up to say
20 miles in a day it is fine, I enjoy riding it, but it is not IMO
a mile muncher, the road bikes better for longer distances.

It is all personal experience, and that is why the idea of someone
taking me on on my folder with me on my road bike over 35 miles
I find quite amusing. For me it would be routine relatively low effort
ride, anyone who could keep up on the folder would be knackered.

As ever YMMV, my opinions are just that, you can take or leave.

rgds, sreten.
