Re: Noob here with a legit question about disc brakes

Try Magura Gustav. I know Madrhino uses them because of their thin profile. I think they are the thinnest ones available.

I have the same problem ..above 52km it shows the wrong speed or goes to zero...

And if it works can you show your modification?
Turns out it stopped acting weird before I was going to do the mods!!! So I will leave it alone for now.

Re: Farfle joins the MENS club

Hey Farfle, I'm really interested in your rear swingarm linkage. How did you make it ? Are they all custom made pieces? Did you use a special BB? Bearings, ...etc? Having the swingarm link on the BB seems like a good and simple idea.

Re: The Unofficial 'CroMotor' Owners Tech-Tips Thread

Unfortunatly I snapped my Cromotor axle yesterday after a heavy acceleration from a dead stop. I had made some room for larger phase wires... but apparently I shaved to much down :(. Now I have to figure out if it's even possible to replace. I have no idea where I can source a replacement axle and/...

Re: The hubmotor bar just got raised....a lot

john, are there a lot of different options with bolt on rims? like diameter, width, ...etc. if so, could these rims fit on those 2 motors you have : the hubmonster HE and the mini monster?

CA speed data acting weird above 50kph

I noticed that my CA is giving me weird speed data above 50kph??? Its giving all kinds of readings and changes really fast. My pole count is right, the shunt value is right. Any ideas???

Re: stuttering controller

do you mean the add-on current throttle mod on the CA??? That gives you a throttle that's proportional to power, rather than torque, so is better in some respects than a typical ebike controller that has a throttle that's proportional to speed, but isn't quite as nice a feel (IMHO) as a throttle th...

It seems to be perfect for hubzilla. 4000 continuous watts and 10,000 burst watts.

Re: stuttering controller

fixed! Well... turns out there is nothing wrong with it! At 100 volts, the throttle is so sensitive that even the slightest variation will cause it to jerk. What we need are better throttles for running 100+ volts. Maybe an Algorithm could be programmed in the firmware to make the throttle response...

stuttering controller

I noticed this morning my controller started stuttering a bit near the end of my commute. It happened when I was accelerating at maybe half or 3/4 throttle. Its the first time it happens and i did not change any settings on the CA or the controller before this. Is there any protection inside the con...

if you're going to run this bike with that much power, I highly suggest some moto rims and tires. The handling is so much better! Talk to John at http://holmeshobbies.com/ He's awesome!

Re: Hyperion EOS 1420i NET3 14s Balance Charger...

Yes, that's too low for a 12s pack. It should be a minimum of 42V and that's lower than you should take it. Oops, it's saying your input voltage is too low to charge at the rate you want to charge at. Either get a bigger power supply or drop charge amps rate lower. it says battery connection error....
