Voicecoils's 2nd build: Giant DH Team (7" travel up front, 8" travel in the rear)
[EDIT] Save yourself the trouble of slogging through this thread and jump straight to the electrified DH Team's new home with Mark_A_W here:

Here are the specs:
FRAME: 2004 Giant DH Team
REAR SHOCK: Manitou Swinger 6 way
FRONT FORK: 2002 Marzocchi Super T Pro
WHEELSET: 24" Alex DJ rims w/ novatec hubs
CASSETTE: 9spd Shimano LX (w/ rapid fire shifter)
CRANKS: Shimano Saint (38t chainring)
BRAKES: Hayes HFX-9 HD hydraulic rear (front brake and 8" discs yet to be bought)
(plus a seat, seatpost, stem, handlebars & pedals of course and a few more links in my chain!)
I'm building up this bike as the second bike I hope to electrify using the same batteries purchased (but waiting to receive) from John @ e-mtb.com.au for my red rigid project. If you're not into downhilling, the Giant DH Comp & Team were extremely popular race bikes for a good few years till the Giant Glory and Ironhorse Sunday World Cup got a foothold as the dominate weapons of choice.
The batteries are two packs of 36v 10ah each which can be wired in series or parallel and are capable of 40-50a discharge. With a cell voltage of 3.2v, total power available is therefore 3072-3840 watts at either 76.8v (72v nominal) or 38.4v (36v nominal). I mention this because of design considerations to be explored further on.
