Coming Soon....

You have beaten me to the punch. I got to the point of rolling chassis last year, and then summer got here and the family took priority. But I'm making progress now! I've been working for the last couple weeks. All the controls are mounted, I now have a J1772 port for charging, the battery is...

The outer diameter of the swingarm bearings is 1 3/8". The inner diameter varies depending on your motor axle width. I did get some with my frame, but I ended up ordering the ones below because I custom made my motor axle...

Depends on what you mean by depend. I mostly want it so that I can verify the cell voltage via bluetooth. I will trust it if it proves trustable. I'm not using it on lipo bricks.

I have a good battery spot welder, and .2mm nickel strip, and then I also have a bunch of 3.5 inch long 1/8 of an inch copper bar that I will solder to the nickel strip first, then spot weld the nickel to the cells. I ordered some copper/nickel solder paste, and I'm hoping to clean the strips...

Got a lot done over the last couple weeks. The bushings foe the rear wheel are made and installed, the read brake bracket is modified and mostly complete. Here is the bike in almost pedalable form.

Ok, after some thought, the plan is to take down both ends to the just under 16mm mm they need to be for the rear swingarm bearings, then use a er-32 collet and collet block to mount the axle directly in the milling attachment. That way I can ensure that the flats are parallel and centered by...

Had a go at one of the axles today. Lathe worked well, needed to do very shallow cuts on this 303 stainless, but we got there in the end. Basic dimensions and bearing races and knurling is done. I need to flatten the end to fit the dropout style brackets and add the channel for the wiring. Thay...

Indeed. Its working much better now. Got the new controller in today and i wasnt aware how much smaller it is. 200 peak 100 continuous vs 300 peak 150 continuous. The smaller it gets the better clearance i have for the front wheel when the shock compresses. This is an interesting development...

Received my new cross feed nut in the mail today, and it's the correct one and is tight on the screw. I need to get a new anchor screw to connect the two; the previous nut had been drilled and tapped for an m4 i think.

1.5mm glass fiber insulation board to make the interpack layers and isolate the bus bars that will conect the pacs.

Some controllers have a line in for a thermistor. This is a tiny resistor sized electrical component that changes resistance when it changes temperature. One would normally open the motor and glue it up under the windings to give a temp reading from the most crucial component. They certainly...

If you use 45 amps at 48 volts you are outputting 48*45=2160 Watts going through the phase wires to your motor. If you use 45 amps at 72 volts you are outputting 72*45= 3240 Watts. So yes, it will increase max RPM of the same hubmotor due to the increased voltage, as well as torque at all rpms...

Well thats a good question. As fast as possible. The 5304 went 135km/h on 36s as a hub motor in a 26 inch rim. I own both a 5403 and a 5404 from the group buy 10 years ago. With the option of changing the gearing now i have a lot more top speed options to play with. Currently i have a 19t and...

I think this is final battery configuration. Ill need to split the pack in the middle of the 4 stack to get it in and out, it just about fits in and out as one big peice but i think once it is welded and shrink wrapped and such it may not be able to make it. The bms fits easily in and out once...
