I have been camping while hiking, cross country skiing and by canoe, but have never camped on a bike tour. Judging from the pictures here and on your site it really looks like something that would be a lot of fun. |
One of the important things for multi speed bikes is the transmission (number and order of ratios) just like in all the vehicle transmissions having an unfavorable relation mass : power (m:P). We call such transmissions (having at least 2 gear blocs - front and rear for bikes) complicate transmissions. Usually it is not known by bicycle producers, so often it can be seen overlapped ratios in bike transmission …. I have seen even 8 overlapped ratios in transmission having 18 speeds (as in my first bike).
There is a theory giving a possibility to choose ratios without overlapping, but I need 20 pages to describe it.
I will say only, that to avoid overlapping, the gear ratios Z/z = W (z – tooth number) MUST be ordered in a geometric progression. The index of this geometry progression for bike transmission is nice to be 1,03, or:
W1:W2:W3: ….. = 1,03. (in the transmission of my second bike, having 21 speeds, it is almost achieved).
But … it is a theory … it is much better to wander by the bike and camp in the wilderness … in fact I do not know anything better … Down is the situation in the end of the biking day … that in the plastic bottle is not juice, not nectar, not lemonade, not tee …
