Technically speaking, if Tesla really wants to sue Electric Bike Company, I guess they could? But I don't think they'd be bothered.
Look at Bolton Ebikes, their ebikes are all named after airplanes.
What about Ford Mustang? Isn't that a copy of P-51 Mustang?
What about Corvette? I'm sure some ships were named Corvette.
Also an ebike motor company called Lightning Rods have this motor called Big Block and Small Block.
I don't think Chevrolet ever sued them for using the names Big Block and Small Block.
I know what you're saying, but I don't know if Tesla will be bothered to sue an ebike company, especially when they're in the different industry and Tesla customers are very unlikely to mistake EBC's ebikes for Tesla cars.
