Front mudguard

In winter there is a lot of dirt under the Bullitt, so i 3D printed a extra flex mudgardholder.

You can find the design here.

Torque arm

To provide a "brake out" of the hub motor, i've made two torque arms.
On top they will be fixed with a water hose clamp.


Gas throttle for crystalyte hub motor.

The original crystalyte thumb throttle won't fit, so i made a throttle of my own.
I can regulate the speed with a potentiometer and there is also a swith for the "cruise" function.


Transportbox part III

Now the small side panels are ready.
They are fixed with some alu strips through the frame holes.

Transportbox part II

The basis for the transportbox is now finished.
I've integrated a small box for the Crystalyte controller as well.

Bullitt transportbox

Now the woodworking part has started.
I use Poplar multiplex, very light weight in 12mm.
I want to make a bottom-, front- and rear panel and 2 sets of sidepanels.
One with an height of 30 cm , another with 60 cm, that also is variabel in width (max 70 cm).

Shimano E-type front shifter.

As i said before, there  was a problem with the mounting of a normal  front shifter on my bullitt, the saddle tube is 45 mm thick , so no normal shifter can be mounted..
I ordered now a new E-type front shifter with a special brace that fit around the bottom bracket.


The special brace and the bullitt frame  has no cable stop. So i must add one. 


I mounted all the necessary parts, so now the drivetrain is complete.
