^^this is awesome
Major update on the bike today! I have figured out the controller programming via a usb-ttl adapter, I have added regenerative braking, I have added a 3-speed switch, I have drilled cooling holes in the motor, and I put on some 26x2.4 CST Cyclops tires.
I also received a new power supply which allows me to charge at 10a instead of the previous 5a.beforeafterBrakes
I have doubled up the brake rotors on the front. I had to dremel one of the pads for awhile to get the extra clearence. The rotors now barely fit inside the caliper; stopping power is superb and the rotor doesn't squeak as much or get as hot. Notice how one rotor is thinner then the other one. Power Supply
My power supply is a 30a 12v 350w power supply from an ebay member called modders.cn. It works very well.controller modsNew TiresCooling Holes
I used a 1 1/8" Bi-metal hole saw. I made a template out of a baseball card to mark the holes. I took the covers completely off of the motor to drill the holes.3-speed switch
This is a 6-position rotary switch I got at radioshack. I have 4 options. Three positions are 100%, and the others are less. I can program them with the computer. I will use them for all-out mode and economy modes.Regen switch
Regen is activated by pushing down the un-used thumb shifter. This works very well. I used a momentry push-button switch.________________________
I rode about 20 miles today. The new tires are awesome! They are very smooth! It is like going from a non-suspension bike with wagon wheels to a 250cc dirtbike! I really love these tires and I hope they last thousands of miles.
The motor had a lot more trouble getting hot. I was still able to peak 97C, but I had to really try. I am and will experiment with fans for cooling. Right now I have a couple powerade caps acting as fins,,, It's not working too wel.. The one thing that puzzled me after today is my max power output.
When I changed the amp limit from 20a to 30a, to 40a, to 50a,, I barely felt a difference. When I hooked up the watt meter I found that I only pulled 27a and 1728w. I had 15+ miles on the charge, but I still expected much more power. I was hoping for 2500w+!
Is there a setting that I am overlooking on the parameter designer?
