Looks nice! On your drawing I just noticed that your head will be behind the rear axle which will make it hard to balance. That's one of the problems with stick bikes.

Shoulders, yes. I think my head will be just in front of the axle. Much the same as the Actionbent I got from Jerry...

Looking good! I never had a problem with balance on the Actionbent. I think the F5 will be even more stable. After you get use to the bike, lower that seat down to 20 degrees or lower!

Had a frustrating week, so I bashed on some metal and made the lower seat bracket. It's not perfect, and a bit higher than I had hoped. But, it's done, and has 2 QR's to release the seat completely.

Now to cable it up and get it ready for a test ride.

Just about ready for a ride. Still need to cut and cap the cable ends. Should get that done tomorrow. Maybe go for a ride, if the weather cooperates.

Sweet rig. Perfect for the Black Bear 100.

Weighed it today. A little disappointed that it came out at 31.2lb. I thought this would be much lighter than my homebuilt LWB (@32.7lb). But, only a pound and a half.

According to Google, the advertised weight was ~26lbs. That was with the Rans seat, not a hardshell like this. And, of course, without pedals. But, they don't weigh 5lbs.

I would guess that my seat brace is lighter than Rans'. My handlebar setup should be close to a wash. I guess these wheels aren't so light, but they're not especially heavy either. Front (steel) fork is a bit portly, though. Might need to find a carbon replacement for it...

That stuff adds up. Plus, advertised weight might not have been sport on.

I would bet the real weight would be closer to 29-30 pounds rather than the advertised weight. Someone in TX weighed his F5 and it was 29.8 pounds. I think the companies weigh them with no cables, pedals, tires, and tubes! My trike weighs over 5 pounds more than advertised. It is a lot easier to lose 5 pounds off ones self than the bike! It still is a nice looking bike.

Maiden flight was yesterday. It wants to roll, that's for sure. Very easy to get going. I rode without my cleats just to be safe. But, I think the next ride I'll try the cleats.

Did find one problem - I laced my wheels wrong. I didn't interlace the spokes on the 3rd cross. The wheels (especially the rear) have very little lateral stability. Going to take them all apart and relace them this week...

Seems my LWB is in the same boat. Not sure how I missed that step. Oh well, live and learn.

I am late, as usual, to the party, but this design reminds me of the Z-bone. A racey bike for sure. Even my fat-a$$ did a 4 hour century on one. Of course drafting off JS, JV, and others might have helped.

Mine is a similar layout, but not FWD...
