Well I think it's fair to blatantly tarnish another company that's blatantly ripping you off. The bike in question isn't just another mountain bike with a battery behind the seat. It's a clone. Some might say that the manufacturer of the clone is deliberately misleading their customers while leeching off another company.I do think the manufacturers are normally a welcome presence including Wisper. although I do agree with you in regards to this thread where there are some slightly unprofessional comments (in my opinion). Most of my comments earlier on in the thread were because it did get my back up a bit one manufacturer tarnishing another so blatently. People robbing ideas goes on all the time in business and most of the time there's nothing you can do about it especially if the ideas not that original in the first place. If you ask me any mtb with a battery behind the seat is going to look like a wisper. They are a well put together product but no major innovation as far as I can see. Hopefully they will put together some truely innovative products together in future and they could then lay claim to some real intellectual property to defend their business.
Yet it does beg the question why they would clone something that isn't exactly popular yet. It's quite possible that the frame is a generic inexpensive frame that's being sold in China. If that's the case then calling it a "clone" would be totally unfair.
