I have no doubt that BMW is thinking about marketing, and probably developing, an electric motorcycle (along with their reasonably successful C-Evolution electric scooter, which I believe sells for around 15,000 Euros). But right now I doubt most of the customers are interested in such a vehicle and I don't think they, or any of the other major motorcycle manufacturers, are going to start
selling electric motorcycles until they perceive the market becoming much larger, to the point where they can make a profit on the venture.
BMW has said that they will be marketing the C-Evolution scooter in the U.S. this year, but so far I haven't heard a peep about it in our national magazines, in BMW ads, or from my dealer's sales staff. At my local BMW dealer, they were so turned off about their experience testing the Brammo Enertia during a couple of weekends in 2009, when they were asked by Brammo to become a dealer, that they don't even want to think about selling electric vehicles. Their position seems to be e-scooters will require a lot of retraining of their service, parts and sales staff, while they see the potential for sales to be very low.
I might add that my BMW dealership was asked by Zero last year to sell their brand, but after some negotiations, the proposal was rejected, apparently due to, training, reliability and parts supply concerns. The shop owner just didn't want to take the financial risk.
Personally, I sure wish he had, though.
