home made e-bike frame. stealth fighter look a like

[louis raaijmakers]

hi,
@chuenchco thanks i will measure the diameters tomorrow.
and do you know if the headtube of a standard cheap bike like my cannondale wil fit a downhill fork?

also i am thinking of ussing a strong 45kmh, 4000w ,48v ,14 inch scooter wheel with a original kelly 6000w controller.
and drilling the rim from the motor and to put spokes truw it an lace it in a n20 inch wheel or so. from a dirt bike or so.
and then using 36v so the bike won't go 80 kmh'.

now i only have a 48v chonismotor with a golden motor 24v till 48v programmable controller. :|
i am thinking of buying a 72v controller and charger from China (greenworks)

i already have 52 headway 10 ah cells to be configured in 72v 20ah or 36v 40 ah.

any advice?
just some thoughts.


thanks

 

[Chuechco]

My head tube has an inner diameter of 34mm. The headset fits into it nicely. I am not an bicycle expert, but this should be the normal size for mountainbikes.
I also have headway cells. However 52 cells sound like a lot. Do you have space for all them? The weight of 19kg is also to consider.

 

[louis raaijmakers]

hi
right now i have a 72v 20ah pack the same as in the stealth bomber. also a 10ah 12v pack for boost or extra 12v items.
and i have made the frame around the battery pack so it wil fit for sure.

 

[Chuechco]

A seperate 12V battery needs to be recharged as well and is unnecessary weight when the lights are off.
You might consider installing a DC/DC converter.

 

[louis raaijmakers]

yes that is correct it just extra at the moment.
but here are some new picture's of the roling frame.

 

[jesset33]

The main frame looks good mate just add some gussets to the front steer tube and bottom corners

Swing arm also might need triangulation to make it stronger and less flexy 8) check out the work by drunk skunk and his Monster bike

 

[louis raaijmakers]

the tube i am using is i thought 2.4mmx2.4 and 2 mm thick

i will ceck it tomorrow

 

[louis raaijmakers]

thanks jesse.
but al the bombers and fighter have it this way so i also want it
i have used thicker steel than the monster bike for the rear swing arm.
so it wont flex
and yes is have read his thread verry nice bike!!

 

[jesset33]

Sounds good Louis

Just remember go easy when testing it and see it the rear end flexes around

 

[louis raaijmakers]

hi
i did some more work today.
first some welding and grinding.

still need to find a way to clean the gaps where i can't come with the grinder.
i thing i need to borrow a small air grinder. now way i am going to file that down.

that was it with the steel work next reply wil be about the wheels and stuff.

 

[louis raaijmakers]

now some idea's of the wheel size.
i have 2 chinees dirtbike's and one isn't done so i borrowt the wheels for my ebike.
becouse maybe i going to use a 14 ich scooter wheel as rear wheel.
so thats why i used the rear wheel because that is the same size as the scooter wheel with a dirtbike tire.

that was it for today next week i will search some metal/aluminium/plastic for the side covers. still not sure what to use.
and i hope i will find some copper sheet +-1mm for making the connection for the battery cells.

see you soon


ps: let me know what you tink of it and give me some advice for the scooter hub

i appreciate that.

 

[louis raaijmakers]

hihi forgot some thing.

the bottom crank
for the foot peds.
how do i make this? the crank is now 12mm wide.
and in need them further appart.
alt least 15cm from each other. so i can peddle past the frame.
i am thing of making for 2 bottom cranks 1 crank and to make it shorter like 18cm.
other wise i need to make a new axle with a milling machine. (alot of work. :? )
but i think that is a bit to wide to pedle.

someone any smart idea's ?

 

[louis raaijmakers]

hello
been working on the bike
now i have a marzocci 888 rv 2
and i have order a damm heavy brushed motor + 10 kg.
spoked in a 16 inch rim with a front wheel.
so now i have to adapt the front of the bike so the front suspention wil fit.

update you soon with more picture's

 

[louis raaijmakers]

ow the motor is in the rear wheel.
just in case you didn't got that point...

 

[louis raaijmakers]

120 a 48v controller running at 54v normal.
headway 16s 30 ampere pack. with 10 ah charger.

i got the scooter for free on marktplaats.nl (same as ebay only it is for the dutch guys and only had to pay for the dive to get the scooter 300km

 

[louis raaijmakers]

i recieved my lyen 18 fet.
but lyen has send my the wrong controller now i go a sensorless...
i will return this controller and ask for my orderd sensored controller.

after school today i will have one week vacation so i will make my bike ready for the mxus 3000 motor and lyen.
also i will make my crank axel so i can pedle.
i will make the side covers from aluminium and the top en bottem of the bike from steel so i can easly make the bike water tight

louis

 

[louis raaijmakers]

hi here is another update.
now with a new head tube and bottem bracket all self made.
also coverd the side's of the bike with 2 mm steel.
the 2 big gaps wil be aluminium 2mm.

here are some pixs

 

[louis raaijmakers]

ow and i also made some good drop outs

 

[louis raaijmakers]

here some pixtures of the complete bike.

ps: i will sell the orange set (32 spokes) of wheel for just a from wheel with 20mm true axel.
i wanted to have the same rims on the rear as on the front but chaged it becouse the wheel has 32 spokes and a hub motor has 36 spoke holes. :x

als fixed a bearing set in the steering tube.

 

[louis raaijmakers]

oke also i have made some progress.
i got my 18 fet sensored lyen in the mail.
but still waiting on my 72v lifepo4 10 ah charger and my 3000w mxus.
but i have made the side pannels and am painting the frame against rust temporarly becouse i want to it to be painted or powdercode'd by a pro. :wink:

here are some pics.

 

[lennovich]

Mooi werk Louis!! Doe zo verder zou ik zeggen

 

[teakuh]

Hallo mede-Nederlander

Ziet er goed uit, alleen wordt deze fiets niet verschrikkelijk zwaar zo? Ik zelf ben ook bezig geweest met een e fiets maar heb alles wat compacter uitgevoerd ghehe ^^ Maar ziet er goed uit, ga zo door

 

[louis raaijmakers]

hallo nederlanders,
vanaf nu in het engels voor de rest van de wereld :wink:

nice to see that more people from the netherlands are interested in e-bike's.
but yes you are right teakuh.

my bike is heavy it weights 55kg.
but yea that when you have +1.4 kwh onboard
but it like it and thats wat matters haha

here are some pics of the build and how i have set the wheels in one line.

i have also upgraded the rear suspention with a fox vanillia rc shock and it is a good inprovement.

more to come.

sorry i don't have a picture in day light.

 

[louis raaijmakers]

here is one video

https://www.youtube.com/watch?v=P7Fc2nykZ9E&feature=youtu.be

and also the max speed i have tested with only a front brake :? was 71kmh... i like it

 

[louis raaijmakers]

did some riding to day (15km) and rode up the steepest "mountain" we have around here.
did verry well only the part where i also can't climb it with my normal mtb. the e-bike also couldn't climb it..
but for the rest it did go verry wel.
i only need to move the rear brake to my steering bar.

then i would say it quite good even on verry hard climbs my mxus 3000w V1 doesn't get warm. also the alluminum side panel acts great as a heatsink the plate was nice hand warm after some good climbing.
i also solderd a bit on the lyen 18 fet.
