I thought I would put this build in this thread:
It is the design series of the I.C.E crusher LFP was going to pilot at the Death race in Tucson
I am definatly racing it 6-5-2010 in Carrothers OH. at a motored-bicycle race.
I will power it with 18s 3p (66 volts) & a 6500w turnigy & an e-crazyman controller sutibly modded to to release all the energy potential.
#1 superior cornering capability
#2 improved brakeing performance
I started with a 24" mnt. bike frame. I need to streach it a bit to get the riders center of mass more between the axels
this photo is taken after I have cut all the rusted cables & parts off
it's ok to mod the frame as it has a "Life time" warranty
next we Jig it up & measure the caster angle. hmmnn kinda slack at 28 deg. I will steepen it to 26ish & see where the trail come out at.
I chop the top tube so the frame will give a little, theres a come-along & a tommy bar to keep things straight heat the lower tube & crank to desired geometry.
Next we streach the rear triangle 4-1/2" to get the wheelbase out to 49"
along side my first build for compairison.
I still need to add some bracing & gussets.
& yes there is pedal clearance. I will put a tiny crank set in there to gain a little but this "bike" will only have pedals to make it a bike. I may put a detent to hold the pedals horizontal & add foot pegs back for head foward rider position.
Tire option atm looks like it will be Shinko 4 ply moped tires on 20" rims. I still have the option of 24" wheels if I want them.
I wanted to put a disc brake system off a CR125 but I have no room on the 20" skyways for caliper clearance. Need to look at some kart calipers & see if I can shoe horn something in (non issue in roundy round but on a road course braking is key)
I will modify this post over the spread of the build. adding & deleting photos as relavancy dictates.
I will consider any sugestions & welcome any comments.
