KillaBICYCLE Electric Bike Drag Racing 3 may 2009

[frohawk17]

i freaking love it. if i had two hub motors i would drag race anyone LOL

[DanFrederiksen]

the headwind doesn't help : )

is the camera vehicle also electric?

[victorvtwl]

u think ur a tricycle in tron

[MrJetjoe]

hay doc, I though I would share with u what i have been working on. regenrtive electric scooters and have achived it. basicly two scooters put toghter but not connected electricly and bolth have regentive costing (no freewheele) 1 pushes the other and charges and u use whatever one has the highest volatge. the other one u probly won't belive but electric scooter without batterys.

[MrJetjoe]

i ssay put a frount moter thats geared for the top end u only gained 1 mph from 1/8to 1/4 mile defently run the same reargear . voltage = power

[Doctorbass]

@MrJetjoe rear motor are enough.. believe me!

Voltage is not power.... power is voltage time current =) and i use both !

watch more of my video.. you'll see i built another one.. a DH bike that top 106kmh using 15-20kW of aceleration power

[richardmg9]

@MrJetjoe NOPE voltage does NOT equal power you scrub. Why not just strap some 9v alkaline batteries together....

[richardmg9]

@MrJetjoe NOPE sure doesn't take your misinformation somewhere else scrub

[richardmg9]

@MrJetjoe NOPE sure doesn't take your misinformation somewhere else scrub, Also motors do not work that way!!! GOODNIGHT!

[liviooo18]

you can make yourself a carbon fiber frame,handle bar and other components that individualy don't weigh much but in summed will be considerable weight loss :)

[pochul]

what the spec ?

[TimpBizkit]

Wear Lycra and pedal - faster

[sbrust1]

ok nice;)

[sbrust1]

top speed?

[Doctorbass]

Time slip:

- recorded 67.9km/h (1/4mile)

-reaction: 1.064

-60FT: 3.032sec

-1/8 mile 14.385sec at 66.8kph

-1/4 mile time 25.093sec at 67.9km/h

- head wind of 46 km/h TOO HIGH

[karmabike1911]

that's the point heh

[smr1967]

i most have missed it,what was you time and speed?

[beaterbaja]

thats pretty cool, is that motor brushless?

[Doctorbass]

Yes it is.. a Crystalyte 5305 mounted on a 24" wheel

[OrthodoxSteel]

I figured it would be! How many volts and AH is required to successfully move one of those mothers? I only have 20AH 48v. Thats my most powerful. Thanks.

[andreschapero]

Dr.Bass : To save the planet all we need is 25kph and lots of torque to go up steep slopes. Long steep slopes.

The bicycle should look like a regular bicycle...light and safe.

Drag racing is a hobby for rich countries with lots of resources.

Range ,range, range and torque....that´s the avenue you should explore for us.

Congratulations !

Andres fron Santiago, Chile.

[swbluto]

Range = Lots of batteries and/or low aerodynamic profile. It's as simple and tried and trued as that. Convincing people they need to go less than satisfying speeds is not convincing in a Western country like the US, but it might be elsewhere in other places that don't obsess as much about time.

[luc59457]

Naw man, I'm proud of him for achieving this. Plus 25km/h is really slow, slower than many speed limits i've seen for e-bikes. Also, racing is not for the rich, I can beg to differ... Although Dr.Bass's Bike here would be rather expensive.... I'm sure he saves a lot on the batteries!

[hal9000v2]

awsome !!!! :):):):):)

[sopdadope]

I think your 1/4 time is faster than my car's hehe

[luc59457]

Can't wait to see the next race you will get more speed recorded than this.

[karmabike1911]

feel the wrath of my goldenmotor!!

nice vid doc

[OrthodoxSteel]

Thats like saying..."feel the wrath of my 250w Cammy CC hub" LOL

[karmabike1911]

heh that the point :)
