Take two e-bikes with similar diamond shape frames from two manufacturers.
Now suppose both of them use the same motor, the same controller, the same handlebar control and the same meter. They also use exactly the same battery and even the same chainwheel.
You'd call them copies I suppose?
Ah, but what if I now say they both use the Panasonic unit which incorporates all of those items? That's different I suppose.
Copying through the use of common components is inevitable in any small scale industry. For their small scale production, Lotus have used parts that appear in many other car makes. Even expensive Jaguars and Aston Martins have often used parts from lowly cars, the switches used in cheap Fords for example.
It's even tougher for startup e-bike companies, they just have to use what is available to get their first models off the ground, since the return from marketing the bikes cannot justify a major investment from normal financing resources.
Just once in a while a brave soul appears with the capital to risk making a major investsment in a new brand as David Miall did with Wisper. Given that, it's understandable that he gets upset at the number of Wisper clones, whether they were intended as such or accidental. Personally I don't think he needs worry, since the resources and experience of that company are starting to produce more unique designs which will not be so easily cloned. The 806fe is an example which is unique among e-folders, likewise the composite carbon frame variant of the 906 model. Also, how many makers can supply either front or rear hub motors, it's usually Hobson's choice, take what you're given. I know he has more unique things up his sleeve for the future too, so the intentional copiers are in for a tougher time in future.
