Giant Anthem SL 0 (Carbon Fiber) Build plus other bikes.

[litespeed]

Hey Tom,
I have the Battery amps set to 64, Phase amps to 170 and this is on 24s lipo. Peak voltage is 100.8 off the charger. My shunt is entered at 1.333. I found that the higher you go with the phase amps the more it peaks above 64 battery amps. With 140 phase amps i was getting 6180watts peak. I picked 170 phase amps because of all the reading i was doing that said keep the phase/battery ratio the same as you increase the current. Peak current on the CA shows 73-74.
The brakes on the new bike im building are Hope Tech V4 evo stealth with 203mm floating disks. These are twin piston mono bloc bad boys 8) The braking surface is 2 x that of my budget hydros on my Talon so im expecting good performance out of them. Hayes stroker ace look simular to these now that ive read abit about them. What speeds are you braking from that requires larger disks?

Strokers are also 4 piston brakes. My bike had new Strokers on the front and I bought a matching set for the rear. Right now I've peaked at 53 mph (85 kph!) but most rides are mid 40's. I just want to have more brake than needed rather than not enough. I find that the faster I can go the more I go fast, obvious or not. I probably will just stick to what I have for right now but really like the idea of the floating disk for longer braking periods where I'm in the tight trails/woods.

I have 55 amps battery and 110 phase on my bike right now. I read anywhere between 1-2 and 1-2.5 is the ratio to use. I went the conservative route. It's supposed to hit 70+ degrees this afternoon so I think I will try 65 amps and 130-150 phase for today's ride.

Thanks for the info,

Tom

man spewing you blew the hadron rig after three days.
looks like a great bike now. im keen to see how the new bike looks when its all together, its a prety big frame yeah? with bigish forks? should be a gooden

Yeah i was spewing at the time. It was a good learning curve though looking back.
The frame is a large size. I can fit 18s4p lipo in the frame pretty snug. Fork are decent size. They are 32 models though so the smallest diameter forks fox make.

Installed my schlumpf high speed drive today. Took about 15mins to do. It was really very simple for those that are thinking about this. Only problem i found was I need a 6mm spacer for the left crank arm so there is no gap with the frame. Other then that im pretty happy with the way it turned out. Heres some pics.

with all those high grade components on it I hope you'll make a carbon battery box !

I couldn't agree more with you. I really hope I make a nice carbon fibre battery box. The trouble im having at the moment is figuring out how i would go about it. A 3d printer would be awesome for making molds to lay the carbon.. But thats out of reach right now.

a friend showed me how easy it is to carbon mould.. it seems like it can rap around 3d corners easily and a mould could be made frome balsa wood or foam. he said butter up the carbon with epoxy first on the under side then lay it on , massage it into place and add the outer epoxy.
just had a look for a realy nice battery box. couldnt find it.. but here's a good carbon fibe artist.

Cheers it looks pretty straight forward doesnt it. Im going to have to do it now theres some others that want to see it done
Cheers guys for the boost ill need to get this done.

 

[pendragon8000]

yeah its a pitty its so bloody expensive $100/m2 or more i think , also depends on corse or fine weave.

 

[dan974]

if you use epoxy then you can use EPS foam to make the mold, (polyster will burn it...) then you can apply a plastic film or mastic, and next some wax or phenyl stuff made to unmold...you can use airex with one glass fiber layer inside and 1 glass + 1 carbon outside, sandwish technology is lighter and stronger, there is no interest to use like 2 or 3 layer of carbon, better make a sandwish...no need to vaccum laminate it, ...you can use balsa or small plywood +carbon if you want to strenght it...but it will be harder to make nice curves...I think EPS is the best, you can even make the mold with EPSfoam+ 1 layer of glasse fiber next polish +wax ...

Update time again. Got My headset bearing cups so now i can attach the forks. Starting to look more bike like now. Cromotor from Methods is in the Air too so it shouldnt be long.
Ive had a think and have a good idea of how im going to do the battery pack for the bike. Im going to make a carbon fibre/kevler shell for them and have it so its removable from the fram for charging. Im then going to have it leather wrapped to a simular finishing that the BT01 blacktrail. Im Planning to run either 18s4p or 24s3p. Will all depend on how the bike handels it once its complete.
I have a few things to decide on also. Mainly whether to use moped tires and rims or stick with bicycle ones and what controller to use. I wanted to use the sevcon gen 4 but im not sure if its worth the time and effort require to get it working. The other option is an Adaptto MAX-E controller but that rules out 24s due to voltage restrictions with the mosfets. Bike is still 2 months away frome being complete, maybe 3 if i go the sevcon path, maybe never too is i go the sevcon path as I hear they are real time consuming to set up. Cant see it being impossible if theres a manuel. Not sure the Adaptto controller has a manuel. Anyone know?

thats what ive been playing with. Lyen 18x4115fet high voltage 50+amps pc usb programable. took about 1 week to get to adelaide australia.
nice work with the shlumpf, and a cromotor? wiked 8)

I have the 4110Fet model on my talon pushing 6.6kw peaks. For this bike im going sinusoidal controller. The reason for this is throttle control in the higher power ranges and also effeciency. Plus also there is no better way to control an electric motor. Ive gone this far why take short cuts?! The shlumpf + cromotor should be fun. I dont have a car at all so im fully committed to this now
One thing thats stuck with me with this build is what JohninCR said which goes something along the lines of "every person should try a 20kw ebike atleast once in their lives" and I aim to test that once with this bike

lol ..good on you(serioiusly). for goodnes sake keep us updated every step of the way now that you've said that. and respect for being sans car and ebike represntAA!

Time for an updated. Its been a while even i thought i was dead...
Rims are on the way(19in Pro wheels). Controller has arrived(zombies 36fet 4115 version). Battery box is being constructed. Everything needed to make a killer ebike is on the way. I have of late been thinking that the carbon swing arm will be the weak link. In light of this i ordered a Giant DH comp with 150mm rear swingarm and kiwi dropouts. If the carbon frame cant take it its back to steel. If the carbon frame takes it then what ill have is the lightest high powered ebike going. I really wanted the E-max adaptto controller but nobody wanted to help me test one. Doesnt matter now though as i have more power then needed. Im actually more fearful of this ebike @ 20kw then my 120kw ducati. Over the next 2 months i hope to put this to rest and give fellow members an idea of what a carbon frame ebike can do. All testing will be done in full motorbike gear. Might get a second Go-pro to get some good footage.

 

[dan974]

in case i got new dropouts....

Update on the Carbon bike. Finally got the bike rideable. Its not finished by a long shot as im waiting for some parts to come(small connectors) to tidy the wiring up and to cut them all to length. Not sure how much power is going through it as I miss placed the shunt value for now so the CA isnt telling the truth. I programmed it for 60 battery and 110 phase amps. running 20s1p A-spec nanotech and i must say that these are well worth the extra $$. There is 1v of voltage sag under full accelleration. They also hold there voltage better and give you a much better idea on state of charge. So far the top speed I have got up to was 71km/h and ran out of room. Need to weight the bike but my guess is its about 15kg with the battery. Ive put 100kms on it and so far the frame is holding up quiet nicely. Ive dropped my plans for this bike to have the cromotor. Instead I brought the DH comp from Moonshine here for that project.
Need to attach photos later as they are too large.

i have faties dropouts that hold my 12 mm axel,if in need...

 

[Falco]

Got around to tidying up my wiring today. got rid of all the white bulky plastic connector and replaced with tiny black ones from ebikes.ca
Bike is still not complete but it is good for now. Still need to hide the wiring and will be moving the battery to just below the handle bars in a bag like Kepler's stealthy carbon super commuter.
Need a new seat post as the 25mm offset on this one makes it way too easy to do power wheelies. Might put some crazy bobs on it too as im very happy with the way they are performing on my other bike.
Finally got some photos for you guys to see.

Falco, looking good. Good to see that the frames holding up. Are u still in maylands. I've just got my blue Phasor running again.

 

[t3sla]

Love the battery setup, can you share some more pictures and links to the bag

Thanks. Im away for work for a week so cant do anything with pictures till I return.
Heres a link to an ebay seller that sells the same bag.

It only fits a 2x5s 5AH lipo per side. Its very snug.

Hey Rodney, Thanks Im still at the same place you came to before yes. When I double my battery its group ride time i think

 

[t0me]

Gis a hoi when you do that group ride, would be pretty cool to see some other ebikes from around Perth

You guys ever hit up the Camel Farm trails on your ebikes?
