Electric Downhill Bike (66 mph run) 

with those sounds, you really satisfied my right ear!!!

Beautiful bike and quick!! Absolutely love the gear shifts, sounds very F1 ish doesn't it...

When my legs and lungs give up I know know there is hope and in years to come battery technology will get better and these bikes will come down in price

I am shocked that your bike chain did not disintegrate from all that power. This is one of the most underappreciated builds i've seen, so i'd like to give you props now. Excellent job!!

having it go through the chain is a good idea so you can change to make it easier for the motor, good job

I loved the comment at :58. My sentiments exactly! My next build will be a similar drive configuration. I loved hearing it go through the gears!

The Harmonic Sounds are absolutely Beautiful MAN!!!

When traveling at these speeds, 'Remember, RED BULL gives you wings. But' what makes up the ingredients? is what stings. May you live long and prosper.

I also saw some dude who converted a beetle into a dragster. 0-60 in 1.5. Very impressed.

Still the coolest home build e bike out there!! Even cooler than mine :P

ahh that bike sounds like a formula 1, so awesome

RIP headphone users.

Ola KIM, agora sim ficou aprovado seu projeto gostei do zumbido troca das marchas muito bom, valeu seu empenho abraço

I love the sound of when it shifts

That varies widely, it's like seeing a car outside and asking what would it cost. It cost me 600$ for a hub motor setup (easiest to do). I don't go as fast as this guy, just over 50kph. Range varies, but I have ridden for 40 kilometers with pedaling before. Check out the endless-sphere facebook page, lot's of build pictures and ideas there!

Very fast- great Sound!

Great e-bike and great acceleration !!! (I like your lcd display, could give some info about ?)

well done what an awesome ride!

Very impressive!

oh and of course there's the fact it's much faster response upon depressing the pedal as you don't have to wait for combustion to occur.

Wow! It accelerates faster than a sedan!

It's a beautiful thing

Nice dude!

Hey man, first of all, sorry for my bad english :D. I just got one question for you, what kind of motor do you use in your bike? I would like to know because i have a bicicle downhill type... and it would really nice that you help me to do the same :D

cool shifting sound @ 0:41 Seriously, gears may be the way to go...this is cool! Are you wearing leathers at that speed?

I'm more interested in single speed (gear-wise) EVs like Tesla Roadster S. Sure the top speed is only 125 or so but the torque, it's incredible :) And not having to shift is brilliant!

That's freaking fast. I got a farbike aka Xtreme xb. I want more power or a awd how can I convert the front hub into an already built on rear hub? And do I need a strong battery or 300 watt is good?

8000watts at the end? Respect! Aren't you afraid your chain/dérailleur is going to snap or something? I can imaging some huge forces pulling at it when changing gears?

so thats what electric shifting sounds like.

or if you can tell me where can i find or get one of that engine.

The shifting you heard was that of the bikes gears not the electric motor

What's the range? How big is the battery. I'm guessing 3 miles, and as big as a house lol.

I Have a DH Bike and want to do this what would this cost not Including the Bike?

nice job what do you get for distance

it must be hot on the calves after a while

and where do i get it at the cheapest price?

She had MORE to give

just curious about what bike you used?

can you add a bunch of "light generators" on the tires to prolong the motor battery time?

:D I guess(!) for MTB tiers it is easy because they are used to much harder (of course different) conditions at downhill ?

can the tires handle that speed?

MORE LIKE 55 MPH THAT'S WHAT THE FUCKING CLOCK SAID

Wow! Over 60 mph, weighing around 60 lb? How much is it? I'm ready to buy!

multi speed transmission? Why for an electric motor?

vaya pasada de bici impresionante

thats too kool

when the litium air battery comes out youll bet your ass ill build one of these, How much for a Good motor and battery and controller?

~8kW peak, thats hot !!

Couldn't you play MP3's of Harley sounds on the bike or at least use clothes pins to hold some playing cards in the spokes?

did You notice the chemtrail upper left corner at start of this video?

no,really what is the range of this nice and damn fast bike ? :)

How Much? I want

This bicycle is literally within 9 MPH of being as fast as my old Yamaha XT225.

Dame dude that's cool how much for you to build me one

highway speeds on a DH bike. holy hell.

Lol it has gears?

I wish i was smart

now show me it on 20 degree hills please

What is the best adult diaper to wear when riding this bike?

When I can buy that watt meter?

hehe electric motors don't shift, it's why electric cars have one gear - drive :P constant torque right up to high speed. At the moment electric cars are premature technology but they have the potential to be faster than petrol cars. We just need better energy system as batteries are too heavy and limited.

I noticed it's around 7Kw, seriously?

I'm so building one know

Put that on my TT bike.

Tailwind....

can u get a speeding ticket for that? ))

can you do a emergency braking at this speeds ? make sure you invest some money in proper brakes and proper tires . Tires like the City jet puncture protection which are like Slicks ,very sticky and they might increase your top speed to 70 mph . and some good 180 mm disc brakes . The reason I'm sending this comment I've crashed my 1000w e-bike , my brakes simply become unsuitable . Now I prefer to stick with 250w e bikes Message from bike Builder to Bike Builder watch?v=CTsVRTtumQQ

Sounds like F1 car..

if only batteries were better...

it looks so slow

a bike has horrible aerodynamics so high speed is very energy intensive. as much as a car

There is no sense DH bike that is e-powered, people are trying to make DH bikes as lightweight as possible and you have one decent frame and fork and you are ruining it.....
