new Kingpins/Spindle Shafts done. 20mm thru axle and 160mm brake mounts Also modeled it 100% including moving parts Weight of the spindle shafts was reduced from "heavy" to 3 pounds not including any parts attached

Made the 20mm spindles. in 3 passes I hit .787 from a 7/8 piece of round bar. Slid the hub over the shaft, marked it, then trimmed the end of the shaft for an exact fit with the dust cap of the hub. Then I drilled the hole in the end and tapped them 3/8-16 LH and RH. Much easier than trying to...

Grin/ebikes.ca sent me a replacement screen and I soldered it in and things are back to normal.

I sorted the shunt resistor misreporting and Grin/ebikes.ca is sending me a new screen to solder in. I got them to compensate me by sending along a free 6 pin extension and a usb programming cable. The replacement for the failed charger is here also so it will be tied in and tested. The...

I would have figured that one out if it weren't for the illegibility of the screen. :/ Can't read anything. Sure hope they make it all good. I was under the assumption that if they coordinated with the controller manufacturers to get a 6 pin output they would get them to agree on a set...

I have been riding my bike to work. It Runs great, Everything is solid. Got the Cycle Analyst V3 in the mail today from Grin/ebikes.ca. Besides the fact that the bottom 1/3 of the LCD does not function, it appears to be a well built piece of electronics. I was able to make out the...

Ding ding ding! Cable gland sounds like one of those industry terms only known by the electrical supplier. But yes. Which size bullet connectors best fit 10g wire? Those seem best. I did a little more research and determined that 10g fits best the 6mm you mentioned. I wasn't aware those...

New charger on the way. The thumb throttle is way too sensitive for the available acceleration. Good thing I have cruise control. GPS said I did 44mph. (true GPS, not tower triangulation) The electronics box is doing an amazing job at getting rid of the heat from the transistors and voltage...

The stock motorcycle bullet connectors going to the motor are insufficient and get too hot. I am building a prototype that has an electronics box that has 1/2" diameter cord grips. A few searches led me nowhere regarding single wire quick connectors for higher amperage. You guys have any ideas...

I looked it up and you are right. 80%~ efficiency. How goes your project tahustvedt?

I'm so caught up in the wholeness of the project that I forgot that I had to supply the BMS with a regulated voltage and current. You're right. A new charger is on the way from GreenTime. Problem solved. Meanwhile the ride is awesome and really enjoyable. The throttle is too sensitive, to be...

Bridge rectification with a voltage regulator, resistor and capacitor would fix that. Off the shelf would be preferred

The jackass at Greentime sold me a charger that failed in 30 minutes and said he would replace it when I purchased a few other parts. It wasn't in the box. Guys got any ideas on how to supply my BMS with the voltage it needs from A/C? 24s 100.8v at full charge I know a transistor failed...

The pedals are all chained up and it now functions as a bicycle. I didn't bother putting in derailleurs because on the next version I'll be using an internally geared hub (NuVinci) Finishing the wiring and fusing tomorrow so that once the body is done it is as simple as popping in the fuse for...

Put a nuvinci n380 inline with a sprocket bolted onto the disc brake 6 hole bolts for power output to the differential? That's what I'd do :) No gears, no variable chain paths. Just 4 sprockets of the same size. They even have a "harmony" system that matches the gear ratio to your pedaling...
