Grant Petersen, owner of Rivendell Bicycle Works, does not think ebikes should be classified as bicycles. He designs beautiful handbuilt lugged steel transport bicycles, my personal favorite of their frames is the Cheviot, but in a
recent blog post he writes "Expressing a disopinion about eBikes inevitably gets misconstrued as being against older and physically challenged people's mobility and independence and right to the same fun others have. That's not our evil plan. We
have no evil plan! It's not whether they're good or bad...It's whether they're a bicycle...of all the levers and wheels in it, the ones that MAKE it a bicycle are the ones that motors replace. You can still pedal, but you don't have to. There's no direct-connection between effort and movement, because the motor takes over. Motors take over these fantastic cooperative movements. They don't "enhance" them or "supplement" them any more than somebody dipping a spoon into your bowl of ice cream is "helping" you eat it...The deal here is that they have a motor so they're not bicycles, they’re motor-cycles, or at least mo-peds. Calling them bicycles gives them most or all of the privileges of a bicycle."
Grant argues he is not debating the merits of the value of motor pedal assist for climbing hills but rather he thinks the dividing line between human and motor powered cycling is one that in his opinion ought to maintain real world legal and practical prohibitions on where to ride an ebike. Contributors to the EBR forums will disagree with Grant's argument against giving us ebike riders "most or all of the privileges of a bicycle".
