Some years ago I saw a Kettwiesel with a front wheel hub motor - the 
battery was mounted just behind the front wheel under the main tube 
(mounted fore and aft so it did not stick out and interfere with the 
pedals) - with modern batteries the weight is less, but it would still 
help.

When riding an unassisted Kettwiesel I rarely notice wheel slippage - 
though when riding the front of two linked Kettwiesels with the rear 
rider not really pedaling, the front wheel definitely skips from side 
to side when climbing steep hills - this is not really a problem as 
speed is very low in this situation.
