Hi every one,

I am from France and i come here to present to you my project.

I hope you will enjoy it...!!

Maybe you're wondering why this name...??

B for built, 52 for the rake angle.

In details :

-24"x4" front wheel with dual disk.

-20"x4 rear wheels, a disk for each wheel.

-Double freewheel

-11 internal gear hub with a additional sprocket mount instead of the disk.

-Saddle from "fat boy"

-Frame totaly homemade in steel, central section is 42mm. Head tube is 50mm.

-Triple tree fork totaly homemade, legs measure 110cm and 48mm for the diameter.

-Triple trees made in a 7175 aeronautic aluminium.

Let's go for some pics:

Thank you guys !!!

I really appreciate because this is my first built and i try to design it as best i can.

For the saddle, as i said i will use one from a "fatboy" (specialized):

 
Thanks ilia-45 !!

I'm gonna to work on the rear arms on the frame, machining again to obtain good fish mouth.

After that, i'll be at the olympics for 5 days so no work on it...

When i'll be back, i'll weld the rear arms and the saddle support.

I really need to accelerate the work on the triple trees...
 
Love love love trike builds. Gonna have to watch and learn. Though all these components and machining shenanigans is way out of my league!
 
Just a little update about the transmission :

The green spocket, between the 2 pink chains is free because it will be for the electric motor...

 
This trike is freakishly awesome!!!
And your using an Alfine 11!!! $$$$$$$$$$$$$

Thanks !!! :D :D

For the Alfine 11, i get it with the rapidfire shifter for 349 € (440 $) in Germany.

In fact, the parts of my trike are from all around the world...France, Germany, UK, USA, Taiwain, Vietnam... :lol:

Yeah, brilliant idea bolting on a second sprocket onto the disc brake mount! I must remember your 'Einstein moment' for a future build!

Build on brother!
