50 miles isn't that bad.. we're starting to see more and more practical iterations of electric powered vehicles.. it's about time!

World fastest electric motorcyle is "KillaCycle" http://www.killacycle.com/ with world record of 174MPH

"43 bhp Agni Lynch electric motors" --- know what, this motors are made in india http://www.agnimotors.com <== Great company, has good name in electric motors for two wheelers and four wheelers.

I discussed with the same company to build an electric motorcycle almost 1.5 years ago.
The total estimated cost to build the bike was above my budget so droped the idea for some time.
Cost of motor could be managed, but getting A123 battery set and its chargers and other electricals where making it move out of my budget. Probably will build one as soon as i get some more money or a good sponsor

Wondering how much the battery pack alone costs..

Cost break down at that time was arround

60K for motor (Agni 72V Motor) Perm 132 could have been cheaper
30K for 72V A123 batteries ( thought was looking more in line of 144v)
30K for Charger Zivan NG5 Charger (550$)
30K for Altrac Controller 24-72V 450Amp (600$)
10K for D2C Convertors 72 to 13V (200$)
2.5K for Throtle
2K for wiring, fuses, connectors etc etc
20K for Bike that needs to be converted to electric
10K for mechanical and electrical work arround building the bike.

Total arround 2Lac

Given the cost, it was hard for me get going with the project I expected it to raise arround 2.5 - 2.8 L due to error and learning methodology. But the machine built would have easily gone at par with any 600CC racing bike, and it would have easily made 60Km in less than 4sec thx to electric motor Killacycle touches than in less than a second (0.8sec) if i am not wrong.

On a single charge it would have gone 60-80kms, top speed would have been 140KMPH to 160KMPH and 80% recharge in less than 10mins of charging (thx a123 batteries) cost per km would have been less than 10paise per km

Any one wanna sponsor the project

The whole project can be done at half the price too, but it would be just an electric bike and not something that you would love to ride daily.


This sound funny and i dont think this is how they would have implemented 2motor, generally 2 motors are used in linear pattern to gain better pickup or intial torque, similar setup is done in killacycle too. Any links to read more about TTX01 configurations ?

There are lot of electric scooterettes in India... i really wonder if there is a market for electric bikes? AFAIK, power isn't controlled by gears.... Can anyone throw some light on this?

Viny?

Would you love to ride a electric bike which gives you powerband of 600cc, comes at half the cost, and operations cost is 100th of the 600cc machine? No Oil Change? No Carb tunings, No airfilter servicing .. so on ..

Power transmission is controlled by gears, Power Output of motor is controlled by controllers.
if you use smaller gears you would get good pickup, good for up hills, if you use big gears, you will get more milleage, higher top speed but low pickup.

I have thought of using cycle gear system in the electric motorcycle, to gain the fun otherwise its as plain as Cars with Automatic transmissions

thanx for the info Viny...

One doubt - just wanted to know if the gears will make the battery to run out of charge faster?

The intial investment seems to be fair to compete with a 600cc gasoline powered bike. So the problem with the bike is that its too powerful and hence of no use in India? Hence no investors?

Why not start with a lesser powerful electric bike? I mean the ones in the market at present are scooterettes and have major reliability issues. Electric bikes in the intial stages will be mostly used within city conditions hence the suggestion.

Intriguing project Viny. Where are you based?

Nopes, Gears are used just to direct how the power generated by motor is going to be used.

Indian/chinese electric scooterettes, compromise a lot for cost competitiveness, they have kind of use and throw motors, that have life only till the warranty lasts, there after "ram bharose" they use simple LEAD acetate battery, which hardly runs for 1 year.

Where as the setup that i am talking about is using a123 battery (Lithuium ion battery, used by top automakers A123Systems ), these have 2000 + charges cycle that means even if you charge it daily it would go for 6 years, it charges very quick (upto 80% in less than 10 min), unlike the normal ones which take overnight. The motors that i am talking about are the best in class and can be used to power electric car.

Why to make cheap electric cycle that wont give you joy of creation and satisfaction of riding. Rather I would wait till i get the right opportunity. I dont belive in medicore jobs, do the best, if you want to be the best.

@rossiter: I am still in India pm me if you want to discuss further.

Didn't know that.

6 years and 10 mins of recharge time! Thats quality stuff man.

Thought you would say that

You have extensive info regarding this field

I agree, even a single 43 bhp motor would be enough to eliminate everything made in India...

Yes, even faster than the Ninja 250 & RD 350 ... For such a powerful & enough sturdy production bike, I would gladly pay Rs. 2 Lacs any day ...

@ Viny: Why did you say that it would just be an electric bike and not something you would love to drive daily ... ??

What i meant was that if i have to build a electric bike then i can build it at half the cost that i quoted above, but this low cost bike would not be something that I would love to drive daily. I understand you already have some experince of low cost electric vehicles... And I dont want to have same....So staying out till have needfull funds to build something thats worthwhile the effort and give joy of creation and riding

I feel building an electric bike is much easier than cleaning and assembling the carburetor on normal bike
