No, it's quite legal. It's the same motor as the Kudos Ariba. Theirs has TOPs (Torque Optimisation Program) which increases torque at low speed for better climbing. Ours has BOTTOMS (Boost OF The Torque On Minimum Speed), which works in a similar way. The slower you go, the more torque you get. Even the 200w Powabyke Euro would be able to climb those hills without pedalling, because its motor also produces high torque at low speed with low power. Normally Steve would be pedalling, but he had to go fairly slow because my bike only does 15mph before power cut-off. Bikes with throttles have a big advantage over pedal-only bikes because you get the choice to pedal or not. This sometimes makes those without them think it's a bit unfair.
