Current post: Re: Weight Weenie Ebike, Nine Months Later

In a few weeks I am going to rework this the power system on this bike so I want update to the current "as built".
First of all I got tired of dealing with the 1-1/8 adapter. I got suckered into the fad. I installed a standard 1" long neck steel stem and turned it around backwards for a more comfortable riding position.

The bag is now bolted to the stem via an 1" Aluminum clamp. These are VERY handy little clamps (takes 5mm bolts).

The plexiglass stiffening bar inside the bag broke. It was replaced with a piece of 1/2x1/2 aluminum angle. The motor controller is bolted to the bar via one of the through bolts. I also added another grommet to pass the wires through.

The seat was replaced with one salvaged from a Schwinn bicycle ... needed something a bit more comfortable.

I do not always want to drag the Travoy around but I did need something to carry things around so I broke down and installed a light weight aluminum rack. As the frame had NO provisions for a rack I used "D" clamps around the seat stays at both top and bottom. Then I mounted the overpriced Travoy hitch to the rack so that I could lower the seat back down where it belongs.

For version two I intend to:
Relocate battery to underneath rear rack
Provision for GM 36Vx12Ahr rack mount battery on top of rack (when extended range is needed)
Replace controller with Grin Tech Phaserunner (i want to try various setting on the motor) Ultimately I will probably use a EMV3V programmable controller.
Add Cycle Analyst V 2.4 (stem mounted) so I can evaluate the controller changes.

The more I learn the more obvious the immensity of my ignorance becomes.
