GoPed Sport Electric Conversion

[Guy H]

Hi

I wanted to share with you my scooter conversion process for electric power.
This is an old chassis of GOPED SPORT and RC electrical equipment

Installed components are:
*Motor : Chinese 6364 230KV from Hobbyking
*Controller : Hobbyking 190-200A
*Servo tester
*BEC
*Batteries : nano -tech 45C 5S 5A X2

Most parts were constructed of composite materials, the final weight is 8 KG.
The motor take me (80KG) easily and never warms up even on long rides.
Speed ​​is 25 KPH with a 1:5 gear and range is about 10-12 KM per charge.

I got it like this:

Really sweet work. Not enough good electric scooter conversions anymore.

I am suprised you dont get faster than 25kph per hour.

[milesinfront]

Awesome job! Is the carbon cut from hard sheet, or did you 'brew' it yourself? Wish my scooter was 8kgs, but then again I'm aiming for 50km/h+....

Thanks for the compliments
Don't be surprised.. now I'm working on 5 cells instead of 6 , as soon as I change my battery I will get to 30.
I have transmission for power insted speed because I live in a mountainous area..

Thanks to you too
I cut the motor and rear wheel parts made from purchased plate (thickness is 2.5 mm)
Plate and the part for carrying made by me with 180 g/m carbon fabric

Consideration in selecting the components were made only by weight since I'm a student and need to take it with me between classes...
I have a few more projects which go much faster, hoping that soon I will have the time to upload them

[def215]

nice! that is awesome!

i guess im not the only one that has converted a goped sport from gas to electric. heres mine that ive converted:

the gasser one in the background has nothing on this one.

yours is way better than mines by a long shot.

[Guy H]

tell you the truth?
I saw your scooter in google search and thats why I built mine

After two months with my scooter it's time to move on...
sold my goped and got myself GOPED GTR
I'll sell the engine because petrol driven scooters are Illegal in Israel and replace it with 80-100 brushless

this is my new toy
hope to open new thread soon ( I can't find motor like this in stock)

[sk8norcal]

nice!
I dislike those solid tire goped wheels, horrible ride.
pneumatic + suspension is way better...

do you see people using these small wheel e-scooters in israel ? popular?
I know kooper, moover, and trekker are from israel.

my goped?

a trail ripper platform should be pretty good. IMO i think thats probably one of the best gopeds to date.

that should be a great electric scooter when its done, especially with an 80-100.

i remember running into this thread, not to scare you about having that scooter, but more of a caution. there have been stories of the front fork failing at the stem.
you can read about it here:
http://www.gopednation.com/forum/showth ... ail+ripper

im planning to trade up to an air-tire scooter soon so i might let go of mines soon too.

[Guy H]

Yes , your Goped..
This chassis lay in my house for a long time and when I saw what you did I started working on my..

Like a car, motorcycle or any other vehicle you are riding it ,a person needs to check it from time to time and maintain it .. Cracks happened somtimes..
the chassis of GTR considered reliable because of suspension.

**Great news! i got myself 80-100 motor from leders hobby yesterday. it was in stock for a few hours.

These wheels are only good for driving on roads. on sidewalks it's a nightmare.
I agree that pneumatic tires and suspension are better..

The only scooter in Israel which use solid tires is Goped Iped..

[sk8norcal]

they have Iped2 with air tires 8", they discontinued Iped....

[Guy H]

This model had just arrived to Israel, looks good!
I personally like to build my scooters

[Astropower]

Hello Guy.

Nice job you do here,
Tell me please, there is no heat problem with such a small motor with high output like this ?

by the way, I from Israel too, i like small compact E-scooters, maybe my next project.
you can see my project: viewtopic.php?f=35&t=38385
i didnt finish yet, soon i will.

[Guy H]

Hi
I follow your project from the beginning, looks very good!

there was not a heating problem because the transmission was for slow speed (25-30 km/h)
The engine stays cold even after long climbs ( My weight is 80 kg)

Because the RC equipment light and have good performance, I recommend you consider using it in small scooter ..

[Astropower]

The reason that i didnt using RC motor,
1. This kind of motor have low efficiency 40-50%
2. Generate lot of heat , that lead to short life time.
3. Low torqe, and high RPM, all this system generate lot of noise.

Generaly, this motor did not designed for heavy loads.

But i fan of small things.
Maybe in my next design i will try combin motor like you have, can you give me link for specification of your motor.

[Kin]

40-50% is not quite accurate... you may be running the motor in not the best conditions to be getting that bad efficiency. The 6054 should be powerful enough, but if you're running near 30mph you might want a more powerful motor. One option is to take a lower Kv 80100, rewire as wye/star, and it should still cope with the power demands of ~2kw. RC motors are just BLDC motors, so they might be inefficient in the sense they're not the highest quality if purchased from a cheaper place, but they can be decent in the right conditions.

Definitively requires a lot of reduction. I've been told you want to replace the ball-bearings on the hobbyking motors if you're running above 5k rpms, but at 5s I guess you're running at 4k and might be ok. The high heat might be a factor of the smaller motor being stressed throughout accelleration in these high demands.


I hear you have some of the coolest scooter designs in israel! At least all the cool ones sn0rkal posts, seem to be from Tel-Aviv.

I think Guy-h is running something like the http://www.hobbyking.com/hobbyking/stor ... duct=18180
