Ok.. so i'm building what i intend to call the " Grin-Mobile "
Rear eZee motor in 700C rim, on a Norco Storm 29'er
I spent over an hour at the local bike shop eyeballing all the possible options, willing to spend whatever it took to get a proper bike for the kit with Thun BB and CA V3 with all the bells and whistles.
It came down to a ladies Norco low step thru with fenders, all black, but the rear rack was smallish and would not take the eZee 48v pack and mounting plate well.. so the Storm took it with nice frame similar to my fatbike Bigfoot with long handle bars and solid frame..
Anyway.. then come the problems, as they always creep up with an ebike kit.. argh.
The store owner looked at the BB and told me it's a 68mm, that was the deciding factor between the storm and another +300 $ model with Rock Shox and XTR components( not square taper BB ) .
I got a drive to the LBS ( local bike shop ) took my helmet with me cuz i was buying a bike and pedaling it home, holy crap, been a while since i pedaled a 10 km non-assisted bike !!!.. :lol:
So, i start with the BB, remove the stock unit ( f'n axiom BB tool i have is tapered edges and would not grab the right side properly, had to resort to big honking clamp vice to remove it ) ... rambling.. sorry.
Low and behold, the BB on this frame is 73mm !!!. NOT 68 ! damit.
Broke out the calipers and compared everything, being very used to compromise with ebike stuffs i come to the conclusion it will bolt up and be " good enough " ...
The Thun is not like a regular BB, you screw on the left side into the frame first, it has a notch that the right side locks into preventing the body from spinning and severing the wires... so after a whole big glass of wine and head scratching... i hesitantly drilled the frame tube..... tried to fish the wire from the BB into it.. no luck... but then realized it's easier to run the CA side wire into the hole first, hook up the connectors, then use that as a fish..

But then.. the problem :
The notches on the chainrings are hitting the frame once the crank is torqued down... i have 2 options.
1 : Remove the crank/chainrings, file/grind down the lobes so they clear the frame, it only need 1mm or so ..
2: Remove the Thun, add the 2.5mm shim that was on the original BB, this will push the chainrings further away from the frame... BUT... the problem is that the left side Thun locking collar is barely grabbing as it is... if i add a shim, i'm afraid it will spin and cut the wires...... it's VERY close....
thoughts ?

I'm sure there is something out there with your name on it.
