    They recently tested a set of lithium batteries at a high discharge rate continuously cycling them charge discharge state and capacity slowly got worse, but they survived over 1000 cycles easily.

    Like everything, it depends on what quality product they use.

    The electric, may be good for freestyle riding, with no technical stuff, but I can't see it doing full on trails events, indoor or outdoors as good as fossil fuel bikes.
    watch these guys,you have to do gear selection on technical stuff, i cant see how you can just rely on the torque of the electric motor to get you through a section, where in some situation as with the fossil fuel bikes you have to bring up the engine revs to get a good burst of power, and you know by the engine sound weather you have enough power when drop the clutch, where as on a electric bike you just turn the throttle and hope.

    And of course the Sound you got to love the sound off a fossil burner over that of an electric drill.

    Why would you ride that long and that gnarly stuff if you don't have to, Its what we do, we love it.

    An electric bike beat a lot of gassers at an enduro...

    while i do not doubt you, would you be so kind as to mention where, who was riding and when?

    Now I've got to find it.
    Don't go away, just talk among yourselves for a while...

    Oh and watch this all electric enduro in the meantime...


    Couple of names from the race...

    Jöel Smets, Fabien Planet, Pål Anders Ullevålseter, Paulo Concalvez, Annie Seel.



    Got the bugger...

    interesting

    expensive

    but interesting

    i would be keen to know what kind of distance they got off each battery/how many batteries they had charging to the one riding ratio

    An electric motor makes full torque straight away but i can still see the need for a clutch and gears. The next problem will be when a speed control cooks its self, or a motor winding burns out or the Lipo battery pack catches fire. I have RC cars and helis that draw over 100amps at 20+ volts and that is the continus load not momentary. There are going to be some huge electrical fires in the future i can see it.

    Yeah I also think that it will need gears. I think that it won't need 5 like a MX bike, but I guess they could also run a dry clutch?? Also the voltage they are running is much higher which gives a lower current draw. But I'd say you'll probably have 400 amps drawing under full load. I guess they might water cool the motors and the speed controllers.

    I saw some specs on a electric drag car. the speed control could handle 2000 amps continus and it rand 50 lipo batteries unsure of there voltage or if they ran in parralel or series. From the rc stuff i deal with this would have to handle 1000amp load.
