List of stuff:
First new ø160 disc brake had wrong bolt hole diameter.

New rim, xxx, bought at local bike shop.
Spokes bought from bmsbattery together with stuff listed above did not fit, to long, and the xxx to thick.
New set of spokes from eBay (venturavorld).
Disc brake mechanical caliper

OLd rim had 32 spokes, motor was for 36 spokes.

Helpful Tool: Spoke Calculator and Wheel Building 5th edition by Roger Musson.

Fitted new wheel on bike. I wanted two torque arms, extra sequrity against damage on the aluminium fork. Fork had a washer recess with to small diameter for the supplied stainless antirotating washer. I turned two new brass washers and put them under the ss washers.

Bottle battery 10s1p 36v test build. tbc...

Studied, searched and read about cable for powering ebikne, type of 18650 cells, to use a bms or not.

List of stuff:
Samsung INR18650-25R 3.6V 2500mAh from www.fasttech.com.
Solder from ebay.
Nickel tape from ebay
10 Cells 36V 40A BMS, eBay
Turnigy 14AWG Silicone Wire (Red and Black), www.hobbyking.com
Turnigy 20AWG Silicone Wire (Red and Black), www.hobbyking.com
Charger, ebay.
(Charger, bmsbattery. Has an earthing error)
EC2 connectors for charging, ebay
XT-60 connectors for power, ebay
Waterproof junction box, eBay user: mgokay
Silicon wires sch10 and sch14, hobbyking

Put together a 10s1p system. Leaded all battery ends. Cut ni tape, and connected cells and bms. Mixed up the bms charger connections, and smoked the first bms. Orderd a second, squached in the mail, nice ebay seller sent me the third at no cost. Marked all wires with numbers, no errors. But a short at the end of the assembly scared me, blue flash and a crack sound, and the ni tape spat all over. I use glass magnifier during soldering, lucky after all. Even more precasion, and fitted the 10s pack inside the bottle with no more incidents.
