need to use an E bike for control collecting!
Can confirm. There's a guy in WA who does MTBO on an e-bike - apparently dunked it in a river up to the top tube at the recent champs, kept going no worries. :)
Two of the three e-bike riders in Newcastle failed to finish after going through deep creeks.
Since controls can't be carried on a bicycle, nor can it be ridden through the forest to collect them, the question of electrification becomes irrelevant (but irrelevancies are of course a specialty of AP).
I've carried controls on a bike many times.
Ad-hoc control carriers on bikes are easy - pretty much anywhere you can zip-tie a piece of poly pipe to your bike without fouling your legs or your steering. :)
Although SA controls are easier to carry than Victorian ones, which are at least double the weight. 6 is about my upper limit in Victoria.
No, Wallaringa's controls are heavy iron so 6 is my preferred maximum also - and the T-pieces at top & bottom are permanently attached so there's no way they'd go into a poly-pipe tube.
