now to get rid of that useless hall board, you can also see that i have removed the hall wiring and replaced the old wiring through the axel with the original phase wire but without the sheath i can fit 6 strands ,a pair of temperature sensor wires and a very thin PTFE hose the reason for the hose will become aparent shortly

This shows all the terminations, what you dont see is that under the heatshrink the wires ends are all soldered and then coated in oil resistant silicone this is then squeezed by the heat shrink hopefully sealing the wire core and insulation against fluid creep. it has been a couple of months being ridden without the battery (under construction) and no drips so far. Temp sensor tucked up against the windings (bottom black thing) and a anti splash breather pipe cap to stop the squirts .
and all squared away with a minimum 2mm clearance to housing and tied down with dacron/cotton woven boot cord.

And the mostly installed item in the bike with one motorcycle tyre 16x2.5" vee rubber up front and a bmx on on the back while i wait for another like the front had to cut of the V brake bosses to fit the moto tyre on the back but its been on and ridden like it looks in the pic for weeks now and it is as nice as pie to ride i dont notive any extra drag formthe motorcycle tyres and the whole frontwheel is only 50g heavier than the original 26er brakes are awesome and the suspension is very plush the slightly altered geometery only a loss of 5mm bb ground clearance with the longer than original forks (130mm manitous vs 70mm mozo ) and the longer rear shock a 190 long 55mm travel dnm replaces the original 160mm long 35mm travel pogo coil of the nodamping flavor (infinite improvement) I love riding of things on it and doing wheelies ( still no battery )

Building a battery now with A123 AMP20 20 ah pouch cells will be 14s 1p to go with a flipsky 12fet vesc6.6 and hopefully saturation will be a little more than the 60 battery amps that the vesc is capable of. More pics to follow , slowgress is progress
