world's fastest ebike? lol

and a here is a other company trying to ripoff some stupid customers....

 

[dogman dan]

Well, they didn't say cheap or comfortable. Cut all range claims in half as always and it's believable.

 

[liveforphysics]

I wonder if they will make a version for folks with external genatals.

SPECS ARE PURE BULLSHIT!!

Unless they are re-inventing physics laws, it’s just impossible!!!

The non-human-generated speed is supplied by a 1.2 kW CM48 V hybrid motor, powered by a 48-volt lithium-ion battery. It charges up to 80 percent in 30 minutes, and up to 100 percent in 150. At its cruising speed of 30-50 km/h (19-31 mph), that range extends to 160-200 kilometers (99-124 miles).

I know and I measured that at 100km/h speed on electric bicycle on flat it take between 6000 to 10000Watts to hold that speed

With a 48V setup they need a controller able to take 200A current… and Yes it’s possible with our material but on commercial setup I doubt it could…

And my favorite: .

At its top speed, the bike has a range of 40-60 kilometers (25-37 miles)

Lol…. They really don’t know what they are saying!!! Lol.. to do 60km at 100kmh on ebike that require 10kW of power during 40minutes… lol…assuming it’s 6kWh of battery… that ebike just have not enough volume to support al the required battery!! and.. that 1200W motor can't do all that power during the required time for 60km range!!

Anyway..

That's why it costs $75,000. Breaking the laws of physics isn't easy, you know. :lol:

They just didn't bother to mention the "downhill in a hurricane" bit.

Hi Doc,
I totally agree with the BS of these specs but I dont agree about the 6-10kw to maintain 60mph it can be done on around 3kw :wink:

 

[Spacey]

Looks like one of these....

 

[grindz145]

I'm not convinced that the specs are real-world. However, they might not be as far off as you think. At 32-34mph it takes me about 800w to cruise on flat ground. That's with a pretty heavy bike and inefficient hub-motor setup (yes, hub motors aren't optimal). I know the wind resistance goes up exponentially however. I wouldn't be surprised if they could get 50mph at 1.2kw reliably. It is manufactured in a way that is far more expensive than any of us could dream of, and I think there are some trade-offs there that were considered.

Well who's going to buy one and put it to the test? :lol:

I reallly want to know how much battery they're packing into that thing... Maybe its 60 miles range with pedalling? lots of it...

 

[LI-ghtcycle]

I nominate grindz145 to be the the first sucker .. .err tester!

 

[vodka]

it has already been tested

[youtube]Bye7mP4H-_I[/youtube]

 

[neptronix]

LOL.. that's pretty pathetic.

I was also thinking.. why would someone spend that much money on an eBike? You might as well buy an electric motorcycle or even an electric car if you have that kind of cash. That's overpriced by a factor of x 75

 

[dogman dan]

My carbon cost more than your carbon, naaa naaa na naaa naaa. That's why. Bet they already sold one to Lenno so he can rub it in on Begley.

Cut all speed specs in half too. Bet they get real good numbers drafting the van all the way. Or they have a one mile test run, and never noticed it's downhill. They then do math to get a "real world" range figure. :lol:

I just realized that the top speed was never stated. 35 mph mabye? 25 miles at 35 mph wouldn't be too far off reality if they have 48v 20 ah in there. But even slowing down to 19 mph, I don't see the cruising range being real without lots of suction following that van at 6 feet.

 

[Hillhater]

from the Gizmag article ..

...It called the BlackTrail, and with a top speed of 100 km/h (62 mph), it’s officially the world’s fastest commercially-available electric bicycle –

Its all hype,aimed at the Hollywood "rich boys toys" market.

 

[veloman]

I'm with Doc on the power required to go 100kph. Only way you'd get to that speed on 3kw is if you have an aero shell, or were an 8 yr old imitating that highway-moped stunt guy doing the superman.


This bike makes me sick, it's just such utter BS. And the public will believe them too.

sorry but your wrong. A 80kg scooter will do 60mph'ish on around (50cc) 3kw ( with cvt transmission ) and people say that a cvt is not very efficiant ( go figure )...

 

[Pedalex]

in the video they say it´s 3.6kw
i was hoping Jay leno would take it out for a top speed run but he was only cruising round

http://www.jaylenosgarage.com/video/pg-bikes-blacktrail-electric-bicycle/1243504/


as a singlespeed pedaling above 25-30 seems to be useless anyway :x so where´s the fun when you can´t pedal and only can go fast using the twist throttle? :|

useless thing - better go for an eRockit

http://www.youtube.com/watch?v=tzsHFka92X8

it once started at ~30k € and is now available at ~12 k €
not really nice looking - maybe with bigger wheels but surely good fun to ride

Sorry but wrong also a (50cc) stock scooter never reach 60 Mph without any modifications, i have past many of them this summer at 50 Mph with my Black Arrow and i'm leaving them in the dust and i'm with Doc.

Good day!

And according to you a 6fet Infineon controller is also capable of 8kw too GWhy...still waiting for proof of this also (been waht? 3months since you said it would be sometine 'this week') ... I'll add the 50cc 60mph scooter to your 'still to prove' list shall i?

stock they are only around 2kw yes they need to be deristricted ( modifications) and yes this puts them upto around 3kw. I have ridden many a 50cc scooter upto 60mph with NO real major mods ( only exhaust and gearing ). You Hub motor guys crack me up

Hi KiM I dont have to prove anything about the 50cc scoot its common knowledge with people that know how to get the most out of them. As regards the 6-8kw out of a 6fet yes its doable and the proof will come its just finding the time .

LOL ...Black Arrow has seen the light...i wonder when Doc and Hal will too

All the best with the build Hal look forward to seeing her up and running

Kim, My Dh setup is already very impressive about the acceleration with the 5303 and 18 fets controller... The max speed is now limited by the current!!.. and... the weak link in my setup is the controller... BUT... i'm assembling a DOC mod 36 Fets Controller now!!

That controller total cost would end to around 225$ total!! icluding a beautifull compact case and quality capacitors and fets....

that will probably do 450A burst.. with that 36 fets ( i'm now reaching around 250A burst with the 18 fets)

that's a real multi 10kW beast!! at 80kmh if i twist the throttle WOT, the front wheel still want to do a Wheellee!!

let say that the 5303 cost 320$ and the controller 225$... the total price is around 550$ motor + controller.. TOP POWER AND PERFORMANCE YOU CAN GET....

now if with these RC stuff someone can beat that with the same performance for acceleration and top speed and.. without reaching 140dB high frequency.. i'll be impressed!

From now i did not seen any RC motor ebike that can outperform my setup Without blowing or breaking a belt...

But.. if someone can make the proof that it can.. Then.. i'm open!!.. i would appreciate seeing one.

Doc

Doc... you blew your Infineon FIVE times in a week i hardly call that reliable. I would bet Recumpence 28hp RC builds to snot all over your MTB Doc, fact Matt gears them for blitzing acceleration not top end is the only reason you haven't seen a rc build posting high top speeds. High speed bores me, getting there fast is the fun part IMO. Hats off to you Doc you have done superb no argument there Great to see the lack of Duct tape on your new bike too mate, looks very nice indeed
