Dave's right, these do make for a great bike. I'm still in the install stage, but having the Tanget mechanics mounted to the bike makes it look and feel awesome. I'm fairly sure I'm at around 40lbs, I'll weight once I get it complete.
So the chainline drama is over and the motor is for the most part installed, still have to work on electrical. I had to space 7mm from the ISCG tab (bottom right), then 3.75mm spacer to the pedal chainring (bottom left) and had to turn 2mm off the chainring adapter (top left) and it all came together with perfect chainlines to pedal and for the drive. I have to make custom spacers now for between all the points on the mount to the ESC bracket.
Now questions...Dave, is there an optimal number of links on the drive chain? I linked it as you can see in the pic, and if i go one more the tensioner needs to do more work to hold it up or one less and the chain is almost straight.
Also, how important is the strap around the downtube? None of the three supplied in the kit work for my frame. I actually needed something in between the longest and the middle strap. Is the strap just to hold everything in place with minimal forces exerted to it? I'm debating on milling something from the front derailleur mount (obviously not used) to the Tangent mount to hold it in place. Bolting the drive side mount with 3xM6 bolts to the ISCG already keeps things in place solid!
