I need help finding a more powerful e-kit.

[parabellum]

I would take last one! It is little heavy, will probably not fit you dropout but who cares, you can climb vertical wall after all.

HA Ha ha ha ha !!!

If these people don't carry the associated throttle assembly,
where would I get the motorcycle type twist throttle? And
also the battery that I will obviously need to power it.

To power this beast you will need suitable controller first. Who sells controllers, sells throttles. Lyen for example.
For battery I would choose RC LiPo for those power levels or A123 at least, if you do not want to carry trailer with 200lbs of batteries in it. It looks like this motor can swallow over 10KW for extended periods (if 5KW is written on it). I do not think your trike can handle such a beast and then again not as front wheel.

[el_walto]

I wonder if you could run 3 tiny hub motors on that thing, probably be hard to find ones with the right spacing and room for those discs.

Hi Parabellum,

I only like to ride for about 20 minutes at a time,
but sometimes as long as 45 minutes. What
battery would you recommend for this?

Hi Parabellum,

I could probably mount two batteries: one under each leg extension.



Ed J

[parabellum]

You definitively need something lite, since your "leg extensions" are movable parts. I would not install anything heavy on those extensions, it will 1 affect maneuverability and 2 put a lot of stress on the moving link. What is in the bag on the steering column?
If your commute is 20 min. then your battery should be capable of 5C at least to not carry died weight with you. To calculate the capacity we need at least distance you will cover in 1 of your commutes.
Anyway, battery chemistrys I can think about are:
RC LiPo (very lite and powerful but unforgiving) Easy modular plug interconnection but manual balancing and care required
LiMn 18650 konions, those with higher discharge rate (look makita tool packs) Little PITA because you need to assemble packs yourself (soldering skills required)
A123 cylindrical or prismatic (cylindrical if you go HV and prismatic if you go Low Voltage to save weight) Those can be purchased ready to go from Cellman.

[Ed J]

Hi Parabellum,

A lead acid gel battery is what's in the bag.
I would like to go with this hub motor (pictured below).

I don't need to go any farther than 20 miles.
And yes, the weight of the batteries is an issue.

The frame weighs 38LBS
The motor (pictured below) weighs 38LBS
And I weigh 250LBS; 76+250=326LBS without the batteries.

What type of light weight batteries (TWO) would
be able to be mounted under the leg extensions.

Or do you think it would be better to put only one on the steering column?

Or how about THREE instead, one on the steering column, and two under the leg extensions? (for better balance and a lower center of gravity)

Ed J

What about this one?

Max efficiency:85%
Max torque:200N.M
Wheel: 12inch Aluminum wheel
Climbing ability: ≥25o
Gross Weight:17.5KG
Brake Type:DISC Brake.

Man, this motor is serious overkill, but anyway, when you realize it you can install it in some serious bad ass bike or scooter.
I would try to put all possible weight over front wheel, it will compromise handling but increase traction.
To be more flexible and be able to split the pack if handling is not what you expect, as well good C rate if in the future you want to run this beast in rear of larger chassis, I would use RC LiPo.
Again.
1) They are lite
2) They are powerful
3) They need baby care!!! (If you do something wrong it can have disastrous consequences)
4) and you need some serious preparation, search and read as much as you can about RC LiPo here on ES.
Here is what I like to use. Have over 60 of this packs purchased and no complains. They are cheap and already protected.
http://www.hobbyking.com/hobbyking/stor ... _pack.html
What controller will you use?

[Ed J]

Hi Parabellum, Is that the charger?

How powerful of a motor do I need then?
Currently I have a 36 volt hub motor
on a smaller frame (T78 deluxe).

I need some "serious" help on the hills.
I would like to top out at 24-30 MPH
and get about 20 miles of travel.
So my goal is to modify a T12

Can you help me find a more suitable motor then;
How fast do you think the pictured motor will go?

Do you think if I get that motor, I should put one
battery on the searing column like the one pictured?
(The one in the picture has a 36 volt hub motor as well.)

How much are they?

How long will it power that beast of a motor for?

[Ed J]

My (36 volt hub motor with a lead acid gel battery) goes about 17 MPH,
and only about 3 miles at full speed; I had it for 2 and a half years.

I think the battery might be wearing out. So I will be needing
a replacement battery for the "trikke tribred" (T78 deluxe frame).

I need some "serious" help on the hills.
I would like to top out at 24-30 MPH
and get about 20 miles of travel.
So my goal is to modify a T12.

Note: a T78 deluxe is a smaller frame size than the T12.
(the numbers [8" vs 12"] represent the size of the tires)

Does the voltage of the motor make the need for different batteries?
(I'm electrically illiterate) Like 60 volt vs 72 volt vs 48 volt motors?

[Ed J]

Will this throttle assembly work?

Here is the model I currently have, but mine is electric of course.

Ed J,
I do not know what motor can fit in your trike, but being front hub short base and high center of gravity do not expect to push more then 2KW in it. In any case, motor does not have voltage or current, it will swallow everything you can give until overheating.
In case of your smaller trike, you can up the voltage and upgrade controller (box that inverts battery DC current into PWMd motor feeding current) and get your 30MPH or more.
Find BLDC sensor motor that fits your bigger scooter physical dimensions first, rest is peace of cake.

Controller will depend on your motor and throttle can be purchase with controller. Good source for controllers is Lyen (search in for sale section), he makes programmable high current controllers capable of 36-150V.

Voltage increase is almost proportional to speed increase if you can feed necessary current and motor can take it.

As example: I am running modified Mxus DD rear hub with inscription 36v 500W. I feed in 100v of charger and ~3000W continuous or up to 10000W burst.

[Ed J]

Hi Parabellum, Won't pumping higher voltage into a 36 volt motor - burn it out faster?

I want a bigger frame for the higher speeds,
BUT, I would like the litter one go faster as well.

The frames weigh about the same: 36 LBS,
the litter T78 deluxe frame is made of steel,
while the larger T12's frame is made of aluminum.
________________________________________________________

There is a manual aspect of propulsion that you add by
"rocking" side to side while you're kicking like rollerblading.
Thus, the larger frame will be better at speed in these two ways.

This aspect of helping it to - keep the speed - has
a certain conservation to the battery as well.

________________________________________________________

Therefore, I would like to maximize my "speed to weight ratio".
Modifying a T12 with a 60 volt e-kit seems to be the best answer.
Where do I find this mini beast motor and all the associated parts?

I need some "serious" help on the hills.
I would like to top out at 24-30 MPH
and get about 20 miles of travel.

Ed J
PS. a new controller and better battery
sounds like the answer for the smaller one.

Hi Everyone,

Sorry I can not give any recommendations on 12" hubs, have never had one in my hands. Maybe you should look in scooter/motorcycle section. It is actually only part strictly dimensioned for your need. Look for everything over 500W. Maybe you can just buy mentioned 5000W monster if it fits your fork, little extra power is good to have.
I will jump in when you got one, with rest of your setup.

The motor you chose burns out controllers.

It will be difficult to spoke almost 10" motor into 12" rim (if you get one).

[silverrich1]

it would be easier to use it as it is with a pirelli tyre, would probably give him 12" with a thick moped tyre up front

[Edg]

Have you seen what I've done with my T12?

http://www.youtube.com/watch?v=C_JRh2ff_cg

1000 watts LiFePo4. 30 mile distance. 2 hour rides. 18.5 mph top speed. Can be made to go faster with higher voltages, but then one risks burning out something.
