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:
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.
