Harold in CR
100 kW
Well, it's been a LONG time coming , but, now I have nearly everything I need to kill myself. :lol: :lol:
Cut a head post out of a BMX very heavy frame, and welded it into a round tube frame that I fashioned from parts laying around.
Bought a 14" Moped Yamahopper front wheel and put a decent tire and heavy duty tube in that.
Had to cut a set of forks out of another frame, and cut and chisel the aluminum steering post out of the fork tube. Had enough extra so no sweat there.
Bought a 2 speed motor from John in CR, and put a decent tubeless tire on that wheel. It comes in at 17½" height, so matches up close to that 14" front wheel.
Have a rear shock from a Kawasaki moto that I bought parts off of on Fleebay.
Bought an Infineon controller that needs the 72V mod resistor and check out the caps. A Leo controller is in the future when money frees up a little.
Bought a new full twist throttle.
Bought one of those $12.00? V-A-Ahr meters that were shown on the forum. Bought a V-A meter. all are LED.
Got a freebie 72V-12V Dc/Dc converter for lighting and such, to include an E-Airhorn, if I can locate one.
Made a deal with a member-vendor for nearly 500 26650 M1-A LiFePo4 cells.
Bought a wad of accessories also.
Now, to get it all put together.
Inside the frame, I will put a center plywood panel, similar to what Aussie Jester did, to mount the batteries to. They will stand upright and be in long rows of 23S 18P, if I go to that setup. :lol: The batteries will sit on "Shelves" that stick through the center panel, and, will be built similar to a spice rack, on a kitchen cabinet door.
That will make them firmly attached with strips mounted underneath to support the weight. All will be tied in real well, and sit in shredded foam carpet underlayment, to absorb all the roughness from the rocky ¼ mile ride in and out of where I live, to reach the blacktop.
The frame will be beefed up with ribs of some sort, so I can stretch light weight plastic fairings over the frame to protect the batteries and keep them weather resistant, and, keep out the wandering fingers.
Controller will-should fit under the moto type seat above the rear wheel, protected from the elements, but, hopefully have an air stream focused on it to help cool it if need be.
Distance inside the frame at the curved seat area is 10½" high. Length is 26 inside and wheelbase is right at 50" c/c of the axles.
The frame is a combo of cruiser-dirtbike-cargo bike, kinda. It will be our main source of transport, so, I need to be able to strap the little woman on the back, along with her back pack, when she goes to the big city and back. Should be able to carry 50-75# of feed and or groceries on the back. I'm sure I have left out a bunch of stuff that will need to be added later on. Top of frame tube is 23" from the floor, so, my short legs will be comfortable sitting on it with feet flat on the floor. Down here, these little guys mostly ride high sitting dirt bikes on the road. They can barely balance it sitting still with tippy toes touching the road on one side or the other
Still need to get the steel box tube to build the swingarm. That whitish piece of 2 X 2 represents the swingarm position.
Only time will tell.
Here is what I have so far. It's a slight;y different view with handle bars showing better in the second photo. They are not what be used, but, works to get a "feel" sitting on the frame. I have short arms, so, had to adjust things to get a comfortable feel.
