re: Electric motorbike teardown

This article is pretty old ( 2007) and much water must have flown under the bridge between then and now. A couple of years back I visited Milan and was shown a complete design of an Electric Sports bike. Newer battery technologies (FePO4 based ) were being explored. I think what we need to discuss here is what is the state of art today as far e-bikes are concerned. Regarding the battery replacement cost - a way is being explored where batteries need not be owned by the bike owners . Like gasoline stations there could be battery exchange stations where a discharged battery could be swapped for a recharged battery in a matter of minutes. The e-bike owner will pay per usage . This will reduce both the up-front cost of the vehicle and the cost of battery replacement a couple of years down the line. As the e-bike population grows such options will become commercially viable

Title should have been "Electric Scooter Teardown". Please bring us a teardown of a product that is intersting. One that breaks the golf-cart paradigm around EV's. Both the Brammo and Zero motorcycles are much higher performing REAL electric motorcycles, and less expensive to boot: http://www.brammo.com/ http://www.zeromotorcycles.com/ Cameron

I think the opinion differs. For some people long term benefits outweigh the "here and now" factor. Just have a look at how the mid segment car markets have fared with respect to petrol and diesel versions. And within the same market, the mileage/cost bearing on sales, and you ll understand that a majority of the performance crowd, still considers the long term perspective as primary.

What I did not see was much discussion of the cost and effort for replacing the batteries when they fail to hold a charge after a few years, or fewer years. Nobody wants to talk about that part. Or will replacement batteries even be available in 3 years? That is what will kill the sales of electric bikes and cars. Why would I wish to spend $11K for a bike and then need to spend another $8K in a few years to be able to use it. For that money I can get a gas engine bike that will last me easily 15 years.

dont know when will the manufacturer understand the difference between 'here & now' and 'in the long term' .. i have the option of a 7k gas engine or a 11k motor drive .. it boils down to my ability of coughing up 11k 'here&now' which more than likely i will be unable to do .. agree i may save a zillion $ later but the seller will want his 11k NOW.. so the point is simple .. make it cheap even if u have to cut back on some fancy fittings.

Thought you might find this interesting. JN

In conjunction with unveiling of EE Times’ Silicon 60 list, journalist & Silicon 60 researcher Peter Clarke hosts a conversation on startups in the electronics industry. One of Silicon Valley's great contributions to the world has been the demonstration of how the application of entrepreneurship and venture capital to electronics and semiconductor hardware can create wealth with developments in semiconductors, displays, design automation, MEMS and across the breadth of hardware developments. But in recent years concerns have been raised that traditional venture capital has turned its back on hardware-related startups in favor of software and Internet applications and services. Panelists from incubators join Peter Clarke in debate.
