The best idea i\'ve ever seen. I really hope to become truth. It\'s the most accessible idea. I even startet to ask about in the bike shop.

1200 watts of usable power...forget the max power of 2400 watts (google e-motors...max power)...and with 1200 watts its NEVER gonna go 70km/h...i have a 1200 watt bike and it will go 40km/h without any input from me and 50km/h with max input...the wind resistance becomes too much of an issue after that. Range given by manufacturers of ebikes is almost always waaay overstated...unless the manufacturer can supply the results of an independent test...or i hear from people who have actually used the set up...the data given is misleading.

what's next, KERS on mountain bikes?

Nice. But there are others out there for mountain bikes. More powerful and cheaper(if you do conversion yourself). Check out http://www.hi-powercycles.com/category.sc?categoryId=26

Use a fairing system to extend range of electric bikes. Most places will require a motorcycle registration to go 50kph on the road.

Downhillers are well known to be aerobic pussies. this merely agrees with that assumption.

@Thomas Noll
everyone knows that the real pussies wear Lycra.
@everyone hmmmmm..... my bike is 17.5 Kilos..... add the 4.4 kg's for the motor/throttle control.... thats 22kg without the battery or the rider. i'll stick to riding back up hills.

Clever, but I rather fancy that a high proportion of these will be sold to the relatively unfit or the 'more money than sense' subset, and that a lot will undoubtedly never see a real hill/mountain but if it makes the manufacturers money...
