I bought this CrMo steel frame from an online classifieds website for $25 and its in pretty good shape. Its surprisingly light.

It looks like the rear dropouts are forged, which is a bonus.

As per usual I am winging it. My original alum bike was a 2009 Specialzed Rockhopper in which I snapped off my alum rear dropouts pretty easily actually.

Here are the specs for the bike donor bike. Different RD and Shifters. Went from 8spd SRAM to 9spd Shimano.

I found the '09 forks stem to be too long, but it fits the 1-1/8" tube. The cups are pressure fit. I either push the nut inside the tube down and cut off. Or find shims. I havent decided. Here is a picture of this problem.

I found I can push down that inner nut.
Not much clearence for my 26x2.10 knobby mtb tires.

I found out my '94 Bottom Bracket is a Shimano Square Taper.
The '09 is a Shimano BB-ES25, Octalink spline, cartridge bearings, 68mm x 118mm.
BB and Crankset both not compatible.
I can reuse my rear stay bar and seat post mounted "clamp style" rack, I will convert the lower mounts to regular bolt on style, and leave the seat post clamp style.

Except mine is clamped to bar all the way around.

See how each clamp is just bolted onto rack, my legs can be bolted onto stay holes. In this picture above, I got the clamps that bolt onto rack, upside down.
Here is the list of stuff I bought.
- MXUS 4504 V2 straight from the manufacturer in China.
- Lyen 18fet RDS
- Ebikes.ca Cycle Analyst
- Throttle
- DC-DC Converter
- 18 HobbyKing 4 cell 14.8V hardcases. Will be going two packs of 74V 10Ah.
- HobbyKing 4mm, 5.5mm bullets, different guage wires, heat shrink, balance lead extensions, balance lead splitters, power cable parallel leads. The "extra hand" is a waste of money, dont bother with their solder, there soldering iron is probably a waste of money too.
*I used power cable 6 (4mm) to 1 (5.5mm) to be most beneficial, 5.5mm bullets and 10,12 guage wire to be most beneficial for building up my battery pack. As usual I overbought* This setup makes it easy to parallel your battery first, then series your individual packs for desired voltage.*
Here are some random pictures.

I think most likely I will be going one speed in the rear, I just have no idea what an ideal teeth count would be. My front crank will be the typical triple, 42/32/22.
