40ah will be over kill to lug around on the bike and I will prob only use 10ah worth on the bike at a time which should be enough. Yes most of the time you will only be pottering around at about 5-10mph but if there is a long hill climb ( at full throttle ) with a couple of stop/starts on the way then this will really bite into the battery also the very short bursts of power needed for popping the front wheel over stuff even you are still only travelling at walking pace, these all add up. My bike in the OP would do approx 10mins of constant demanding trial sections with 10ah or travel about 6-8miles for normal offroad riding ( mx style ) with 10ah so even the trials stuff is very slow, its very intense on the batterys. Putting this into perspective when competing in a trial there are around 40 sections that are marked on and each section will be about 1-2min long everything else will be just riding offroad style.
