After getting some great info and tips from the sphere over the past few weeks, I've finally started to order parts for my 2nd build. As such I thought I may as well turn this into the build thread. The next 4 odd pages contain nothing but my research and help/tips from ES members. Ill reserve myself a few spots towards the end of page 4/start of page 5 for a pic log.
This particular build will be using a Avanti D8 from 2002ish... a cromolly frame, and an overall good looking DH bike if you ask me...
Here is the rough idea of what it will look like in the long run...
Initially however, since I have a total of 0 exp points in the area of mid drives, Ill be bolting everything/welding everything to the current frame. once i've got a rough system going ill either build a 2nd similar one for the norko before modding the frame to house the drive system + batts, or if I can stop the norko from breaking spokes like dry pasta then ill leave the HT on there and ill go strait into modding the D8 frame.
Im hoping to have the intial 'bushpig' version running before uni starts in march next year, but chances are ill go over that target to some degree.
With luck ill have enough done to start, and possibly finish the frame mod in the mid year break.
Wish me luck fellas.

The problem is that there's a few too many options, Im kinda at a loss as to what to go for... the options as I see it are a recumpence asto + v4 system, a cyclone 1200w, or going out on my own, probably using a motor like this http://www.robotmarketplace.com/products/MAG-S28-400.html
or flying monkeys http://endless-sphere.com/forums/viewtopic.php?f=28&t=19841
I really want to keep the rear gears on my D8 for both myself and the motor. Even if its only 3 spd or something, I'd much prefer it to a single speed for the motor. Is this doable at higher power levels (~4-5kw peaks)? the ultimate plan is to build something like timmas bike, cutting out the lower downtube of the D8 to put in a large steel box that houses both battery and motor.
The question is, what to go for?
the cyclone is a bit short on power for what I ultimately want (3-5 peak, less than 1kw cont.) and also noisy as hell. on the other hand its cheap, availalbe, and relatively simple to get up and running. (now if only my women were the same
The astro is a real stretch in terms of $$, I'd have to wait a few months to afford it, and even then Im guessing theres far more to buy than just what you get of recumpence (more frewheels etc), but unlike the cyclone, its relatively quiet (on a RC scale anyway) and near bullet proof.
And going out on my own could potentially be cheaper, but will probably take ages, since I don't yet have all the knowhow, and may not be as reliable. Chances are it wont actually be cheaper either...
My thoughts are to start with a cyclone, as their cheap and set me up with a number of bits and pieces that ill need in the future if I decide to up the power, but my main concern is partially the racket they make, and the concern that the parts wont be good enough to handle it If I bolt a 3-5kw 80 100 or a astro in place of the cyclone motor... in wich case I may be better off just saving for the higher end kits?
So wadda ya all think? Go with the cyclone, since it looks like it'd be a good introduction to building a mid drive? or save and dive in the deep end with a recumpence? or just say Fk it all and go out on my own??
