How far do you need to go, what temps will you be riding in, and are you sure electric is the right type of bike for this?
Hi Torqu3 thanks for your reply. The total range we are travelling is 450 miles -its between Greenland and the Geographic North Pole, but we are planning to start a testing run this September from the Svalbard Islands to see how we the battery run down times will be. It has to be electric bike because it's pulling our sledges with payloads of monitoring terminals, and with the distance we have to travel every year to deploy the terminals of 450 miles, we need the torque of the battery to be our mule. It doesn't matter if what we end up with is 50 miles max runs before batteries die, because we have to stop and stagger anyway to deploy the terminals on the sea ice every 100 miles, and in between (every 50ish) we are stopping to drill into the ice to take samples, as well as use our UAV drones to capture imagery using synthetic aperture radar. And added, is that we know that we may need to do some modifications including some bespoke wrapping around the battery casing itself just maintain a warmer temperature within the battery in comparison to the natural atmospheric temperature. We are not looking at temps below -20c, as when we do the full run in the April period annually, the Arctic has already warmed up to be a little less hostile, and we do our September runs, its just towards the end of peak summer melt where temperatures are coming down from there peak in preparation for returning the Arctic to a place of darkness and coldness throughout the entire winter where the more aggressive negative temperatures and winds apply. We are pretty handed team (I was an ex Super G and Downhill skier before returning to science, and my friend is an extreme stand up paddle boarder, and one is RNLI so that we minimise finding ourselves in trouble in need of SAR. So to be clear, if we can fix a solution to be able to test for distances of 100 miles from this September that is really what we are needing, in the hope that we can work out how to create a charging programme structure for the bikes for the full 450 miles we need to do, so that we can get in and out of dodge. The job is to deploy the terminals, get across the ice as fast as we can, with some torque aid in the lightest transportation method possible to be able to over distances, hence again, it simply has to be electric bikes, and were ok with been Guinea pigs per se
