Wheels like that would be fine for a flat surface. Which it isn't. I expect the thinking was that they needed the largest contact patch possible in order to avoid sinking into the snow, hence wider tyres at low pressure, and large wheels would have been prohibitively heavy. But the 'solution' is pitiful, and I feel sorry for her having to lug that thing. It looks like it's been designed by someone who knows very little about bikes.I too thought that hub gears might be better, but I can't imagine a lube that would work adequately at those temperatures. I suppose they do have motorised vehicles which must have something, but I guess they are warmed by the engine anyway.
