Yes, they're geared for our legal speed so no more available, but they are great hill climbers. The Torq will be fine if you don't have steep hills, but if any are steep, the Torq will give you a bit of a shock after the Powabyke, since it will make you work a lot harder to get up them.
The eZee F series bikes give the best of both worlds, power almost identical to the Powabyke and even better hill climbing, together with the ability to derestrict and get up to 22 mph.
US and Canadian bikers often seem to like heavy bikes and 40 kilo models are common. That could be due to the bulk of many the other side of the Atlantic, heavy bikes more suited to them.
