Hey Vi,

Front wheel suspension: wow, nice build.
Except for the 'front part - pivot' attachment the 'suspension fork to frame 
tube' seems a little weak too. Why not weld two extra tubes left and right of 
the front wheel to make a triangle (as in the attached picture). Just an idea 
to make your ride safer...

Happy cycling,
Patrick

Hi All,
The original build, http://www.youtube.com/watch?v=liEgAoT_8eI, is modified 
after several months of testing.

BB-EOS length is shorted ~3in (4in tubing), to reduce pedal reach and to 
increase the knee clearance of the shock posts. Legs are more comfortable now.  
Reaching the pedal too far can put strain on the legs, despite having smaller
 wheelsize (24") than the FP02 (26"), 
http://www.youtube.com/watch?v=ursy9LxXlqc  Compared to the FP02, seat height 
is 20cm less, but at 36cm, it still high relative to the survey.  We'll see how 
it fairs in comfort vs. the FP02 over the next few months...
The pivot joint is reinforced, after it broke during testing,  It's still the 
weakest point in the bike.  Perhaps another round of reinforcement is in 
order...http://www.youtube.com/watch?v=SsK3sF1P-HQ
The video also includes some build details, the idler, fork modification for 
sprocket clearance, front frame, and rear frame...
Wiki page is also up, http://en.openbike.org/wiki/FS24P
Cheers,
Vi
