What's In a Name?
...Since huge numbers of Joe Public still don't know e-bikes exist, there's a lot to be said for the names reflecting what they are or do, as in Powacycle, eZee and Easy Rider...
I see your point, however, I maintain: are those weird names absolutely necessary?
The Toyota Prius is a state-of-the-art hybrid car, (half petrol, half battery power). But for those unaware that the Prius is a hybrid, there's not much in the shape or name that alerts them to the difference. Prospective buyers have to be told. Which is all to the good, as it doesn't label the buyer as some sort of climate-change evangelist or a 'tree-hugging, Greenpeace dinghy-interception-activist'. Just an ordinary family in an ordinary car to all intents and purposes. Which helps sales amongst those who fear the stigma of being labelled as radically different to others.
As we all know, almost every member of the non-cycling public regard electrical bicycles as wholly designed, specifically for only those who are either disabled, infirm, or not in full health. That's the perception of a large proportion who remain unconvinced by e-bikes. Maintaining a separate 'brand' image of e-bikes may foster that belief for longer than is desirable in the UK, when in fact e-bikes are for everyone. I'm pleased that the two latest offerings from Kalkhoff look like straightforward bicycles at first glance. (And are capable of being pedaled home as such, should the battery run flat). I think there would be far more rapid acceptance of the e-bike if more were offered for sale, side by side of ordinary bicycles instead of via mailorder/online only. (Easier said than done, I know).
The labelling of those who ride a bike that is perceived as intended for the less physically able would soon evaporate. I've been surprised more than once to see the latest offerings of cars with interior conversions that accommodate the more seriously disabled. Gone are the light blue, three-wheeled fibre glass, toy-town-like Noddy cars of yesteryear. Now more and more ordinary cars are being converted. You won't know, (nor indeed need to know), the driver is disabled until they get out of the car. On the highway the disabled driver is nowadays label-free. Total integration.
The e-bike is closer to a bicycle than a motorcycle, so I don't see the need to segregate the e-bike, although I know most members on this forum, are proud of their e-bikes to such an extent that they WANT them to stand out as distinct and different from ordinary bicycles. Come the day when you approach the bicycle sales assistant and they first ask, which type of bicycle: non-powered, or with some form of power-assistance? as a first question because the names on the bikes offer no clues.
