Hi ROG130,
I too have been building a full carbon framed ebike. I used a new 2012 Giant Anthem SL 0. Slow progress build is on here somewhere. I should have it finished in 3 weeks. All parts have been ordered and waiting for the final parts.
I like your frame. Looks good and should be a good base for your build.

I have a Scott Ransom Carbon 10, I never thought of it as ebike material, but maybe you intend to apply hacksaw to frame? This could get interesting, I love the three level setting of the equalizer though....

no no cutting this frame up
i wish to keep the std look of it and keep it light as i can
but wish to keep the speed to 30 to 40 mph
i am looking for a setup that i can use as a e-bike as well as a std mounting bike #
we will see how it will go :mrgreen:

Very nice frame. Are the dropouts aluminium? Looks like you have plenty of anchor points to attach torque arms too. Will be interested to see what you come up with.

hi kepler
just like to say i love your carbon 29er build
when i see your 29er build i said to by self i wish to build a full suspension carbon ebike
i have a custom built intense m3 i love it but its in ya face looks attracts the police
and its no light weight at 46kg or 7.2 stone so i am going to sell it
http://www.endless-sphere.com/forums/viewtopic.php?t=42121
still the new build
the lower swing arm is alloy just the bottom part and the dropouts are aluminium yes lots of good anchor points
the frame is used and has dings and marks on it so i am going to flat it down and re-clear coat it in 2 pack ici clear
should look good me hopes
will add some photos this weekend of me starting it :mrgreen:

as for a motor i have a hs 4080 but i think it going to be a bit over weight for it
:mrgreen:

s thinking of using :mrgreen:

g the mini conhis motor or the same as you the 8fun
what sort of speed you getting out of your 8fun
i am looking for about 30 to 35 mph
how is your carbon frame holding up i love the way you got it as you look at it you would not think its a e-bike :wink:
thats how i am hoping to get my build like ????? is it a e-bike or is it a std bicycle ?????
love to see a video of your 29er on the road 8)

ROG130 · Sep 27, 2013

well i started re- clear coating the frame to day did the top rear swing arm did it so all the frame numbers are still there ect looks a lot better
now i have flatted of the rough battered ransum transfer stickers 8)

Hi Rog, I'm thinking along the same lines, sell my greyborg and the big dd motors and get a carbon frame and small geared motor. Good luck with your build!

ROG130 · Sep 28, 2013

thanks stanford
hope i can sell some bits to finance this build
i got my m3 frame and 2 1000w kits to sell and the new 48v 20ah a123 cell battery to sell
then i can start it then

Why dont you go a mid drive? there are some real nice kits avalible that would suit a nice frame like this. This one for example http://endless-sphere.com/forums/viewtopic.php?f=31&t=50188
This set up would make for a great lightweight setup. Go the 750w system. I would go for this had i not modded my drop outs so it cant be undone. Just an idea that i think would be awesome.

i will look into it but i am not a big lover of mid drives

ROG130 · Sep 28, 2013

ha new part for the build
truvativ stylo carbon crankset 8)

Falco · Sep 28, 2013

Nice Crank! Hope the rest of this build follows that level of quality. My build is running a mxus 500w motor + kit that hyena put together for me. Will be running somewhere between 3-5000watts through it on 20s lipo. Maybe this is the kind of motor your looking for with this build if you dont like mid drive??

ROG130 · Oct 1, 2013

ROG130 · Oct 1, 2013

luigi · Oct 5, 2013

Hi,

Snap, it turns out I've just done the same.

Details to follow, here is a crappy pic.

How goes yours?

looks good my one is still in bits just working out what bits to fit
what setup are you using and how is it going
details please :wink:

etard · Oct 6, 2013

I have to say, this is the last frame I would think to convert to electric unless one were to chop out a section and replace with a structural battery box.

And now I have to go check that cable rub area on mine...

etard · Nov 3, 2013

I hope I was not discouraging ( I hate it when people crap on your idea before they know what they are talking about), any updates on this build?

kudos · Nov 5, 2013

Rog,

Where are you going to put the battery?

Kudos

Kepler · Nov 5, 2013

Hey Rog,

Nice choice of motor and controller. I am glad you have gone geared hub rather then big direct drive for this build. I run a Bafang code 12 on 80V and 3000W on my Fighter. This gives me 65 kph flat out and enough power to tackle just about anything I can throw at it.

In regards to batteries, you have a bit of a challenge with this bike to stay with the light weight stealth approach. I would consider the handle bar bag approach as a viable option. You could even look at large seat bag and handle bar bag giving you about 600Whrs.

In regards to my carbon 29er, the frame is holding up great. I now have it setup with Fox Float front forks and use the bike not only for commuting but also quite a bit of single track work. I can understand why some would wonder why bother with a carbon frame but lighter is better even on an Ebike. And of course, carbon just looks great no matter what type of bike it is. 8)

thanks kepler
i was thinking of getting this from keith in ireland
he got me the motor and controller and he gets them from coghog on e.s
its not to big and yes i think the handle bar bag approach is best to
this is the specs he sent me below

The batteries are 58.8v max, 14S 10Ah and are made up of 14no 9959156-10c li-ion pouch cells. They are as the model name suggests 9.9 x 59 x 156mm and 10c which means they are capable of 100A continuous current. The BMS is rated at 50A cont with 120A overcurrent and also keeps the cells in balance and has a temp probe buried between the cells. The pack dimensions are approx. 80 x 60 x 320mm. :wink:
