I bought mine from the USA, I live in Canada. These Bikes are very well made. They have 2 settings, street mode gives you 500W to the motor at 20mph or 28kmph or competition mode gives you 4500w to the motor at 50mph or 80kmph. I have had mine up to 55mph with peddling off road. Rang is 52 miles at 25 to 30mph, Charge time 2 to 4 hours. Oh what fun!  

That bomber goes so fast! Looks like a lot of fun. Thanks for sharing!! -Trev

awesome invention...its like peddling an alternator to give juice to your battery...its like endless power unless ur alternators is toast!

fnucking awesome bike. combines best bits of mountain bike and small motor bike. so much more fun riding a fast bike without shitty engine noise and pollution. and it looks cooooooool. bet it feels like your flying

Beautiful bike! But I do like it when the rear wheel is much broader front...I wish you all a good mood! :)

Lol i bet the people you were riding past on the street where like, "wtf??? A bicycle going faster than ME??"

So fast. Looks really cool.

I love it, I'm lazy and reckless

Man these things are Old Ladies Bikes, gimme something you got to Pedal to get it Rockin!

Lol, No use the wheel to power the generator. A small permanent magnet wind generator puts out higher amps and watts per rotation the faster you spin the shift the more power you generate. By using the wheel or chain connected to the electric motor and then to a inverter you have permanent power, and all you need to do is ride you bike to charge the battery. Oh and the the generators are only about the size of a 100 watt electric motor so not much extra weight. (And for those of you that think I mean bolting a wind mill to the handle bars and ride down a hill although funny.I think your missing the point.)

So, I just found a stealth bike frame on ebay for $349. i'm about to build one, these things are incredible.

nice job with the camera

How does the saddle feel? Concerned about prostate problems? Would the "hurricane" model be a more comforable option? 

Holy shit... I WANT ONE!!!!!!!!!

Here in China, e-bikes go 35-40mph standard. (50-60kmh) I know because I ride one everyday. I think its funny to see these "world's fastest" and (99% of all ebikes on the planet) .. most bikes in the world are in China, and in China , 99% of the bikes go faster than 20mph

very nice vid keep it up ...
