I got a few updates:
New tires, they are Cyclops 26x2.4 @ $17/piece shipped!! Maxxis worm can stay in the ground! Not paying their prices.
12V regulator to supply lights, brakes.
Temperature sensor switch (to run fans cooling down battery pack-experimental)
Headlights n switches.
I made an extra positive wire from battery pack to go to the frame's key switch which activate the regulator. Off switch cut off power to it so no parasitic drain when not in usage. I added a 100ohms resistor to the LED brake light to make it dimmer. WOrks great.
I use the bike to cruise around the ngbrhood for some fresh air and if its a nice sun-less day I commute to work. Its a 10miles trip each way. I would use it more if I can find a safer route. More than 4 miles I gotta be on the main 4 lanes street with vehicle going 60+mph. There's the emergency lane which I ride on but its still not too safe knowing folks texting and driving and may not pay attention to the road. I ride around 20-24mph, bike max speed at 32mph.
I did some rough calculation and come up with 24.4wh/mile which my new pack will do around 100miles per charge
Worst case senario with this used/recycle battery pack is 20-25% less capacity I still have atleast 40A pack wich will yield 80miles/charge. I have not run it til bms cut off, first few charges I ran around 2000w/hr before plug it in charger.
This used/laptop battery pack cost around $250 in parts @40A (worst case), definitely a GO for an avg DIYer. You can't find a premanufactured pack at twice the price for the same power.
Coming updates: Front suspensions (Rockshox Domain R)
