    It's on both sides. I was wondering the same thing.

    Its interesting how power consumption and power delivery works on electric bikes. They run out of steam faster at higher speeds than they do for around town. Therefore there might be more scope for it in stop/start off road formats. Also the power delivery is a little odd on what ive seen - there are no "gears" so they have to limit power delivery otherwise they are just producing a backflip machine.

    But can you imagine a movie like "Days of thunder" being made if all the engines were electric:eek:

    Sounds like the future is knocking on the door of change... I wonder what noise it will.make.... I want something to list in to...

    Energy density of gasoline: ~50 MJ/kg
    Energy density of lithium-ion battery: 1 MJ/kg (being generous)

    Assuming fuel weighs about 6 pounds per gallon, 2 gallons is 12 pounds or ~5 kg, which is 250 MJ of energy. A battery with equivalent energy would weigh 250 kilograms (500 pounds)!!

    Lots of people talk about how battery technology is going to get way better and this problem is going to disappear. I hope somebody proves me wrong, but I don't believe it. It's not just a technology problem, it's a chemistry/physics problem, and lithium is pretty much the best material for this, so we won't see leaps and bounds. Even if they double or triple the capacity of current batteries (which would be a huge leap), the weigh penalty is going to be really big.

    Electric bikes will be fun for backyard trials, short trail rides, and commuting. We'll never be able to race a traditional enduro or do far-out dual sport adventure riding on them, IMO.

    There will always be advances, some will be huge. Did you see my post with air lithium bats? Very light weight / more power. Also E-bikes as not burning energy all the time (no idle or off throttle) and can regen some while braking and there are efficiencies the gas bikes cant have. We are at the infancy of this tech and already have bikes that will do 70 miles plus. Most off road bikes are good for 35-45 miles on the stock tank and most races know this have have gas stops. Its not unreasonable to see a future where you do a quick swap at a "gas stop" and continue on. modern gas engines are FAR more fuel efficient and powerful than they were 50 years ago. Things will drastically improve IMHO. Lots of effort in this tech as it is the next big thing.

    Thats what they said about 4 strokes before Yamaha and Doug Henry.

    Telsa cars are fast and go 300 miles. If there was an infrastructure like there is for fuel stations for E-cars we could do a 2 minute fuel cell swap and be good for another 300 miles just like we do with gas stations.
