ANSWERED Assembler has front brake on the right side - does it matter?

Recommended Posts

The reason for the spoke design is that there are two sources of stresses in the rotor. The first is mechanical stresses due to torque and the second is thermal stresses within the rotor. As the braking surface heats up, it expands. The inner portion of the rotor near the hub is comparatively much cooler. With the outer braking surface expanding with higher temperature and the temperature of the center remaining largely unchanged a thermal stress is imparted on the spokes. The spoke design is specified such that the mechanical stresses and the thermal stresses occur in opposite orientations, attempting to cancel each other out and lowering the total stress in spokes as opposed to adding together. The result is the “sweeping forward” spoke pattern.

Futher more, if you have the disc brake on the right side, the front fork would be turned the wrong way. You should think about changing the assembler, because mounting the brake or the wheel or even the fork in the wrong direction is highly unprofessional.

I too would be wary of a professional who mounted the forks or wheel backwards on any bike. It might not hurt to also go over the rest of your bike to make sure it looks right, all the nuts and bolts are tight, etc. Just to be safe.

      (description of the C parameters follows)
      Step by step / Details
      What you should now to set up your KT LCD3 display:
      General Settings:
      Under power off status, hold the „power“ button long, the meter is turned on. Within 5 seconds after boot-up, hold „up“ and „down“ simultaneously for about 2 seconds. Now you are in the settings menu.
      (between each setting parameter press „power“ to save and to get to the next parameter)
      Max. Speed: leave it
      For Europe: set it to 25 km/h to be on the legal side. Wheel Diameter:
      set it to what it is: 29 inches Metric and Imperial Units:
      your choice After finishing metric/imperial unit settings, the speed and mileage units stop flashing. Within one minute after stoppong flashing, hold „up“ and „down“ simultaneously for about 2 seconds to enter the P parameter settings environment.
      Need values for our motor are (http://www.szbaf.com/en/components/component/motor/rm-g06350d.html):
      Cadence (Pulses/Cycle) 6/1 Reduction Ratio 1:5 Magnet Poles 20 P1 Motor Characteristic Parameter Setting Mode
      P1 is motor characteristic parameter setting mode. P1 = motor gear reduction ratio x number of rotor magnet pieces, just rounding if there’s any decimal.
      Sondors: Ratio 5 x 20 Magnet Poles = 100 = P1
      P2 Wheel Speed Pulse Signal Setting Mode
      P2 is wheel speed pulse signal setting mode. If wheel generated 1 pulse signal by a revolution, P2 should be set as1. If wheel generated 6 pulse signals by a revolution, P2 should be set as 6. If users didn’t configure the pulse signal system, and then P2 parameter setting can be 0. The setting range of P2 should be between 0-6.
      0 : motor hall sensor only (speed is only shown while motor is working)
      1-6: Pulses per Cycle
      Sondors: Cadence (Pulses/Cycle) 6/1 = 6 = P2
      P3 Power Assist Control Mode
      P3 is for power assist control mode, when P3 parameter setting is1, power assist control mode is gear 5 of “imitation torque control” mode, when P3 parameter setting is 0, power assist control mode is gear 5 of “speed control” mode. P3 parameter needs to be determined according to the distributed function of the controller, its setting range is 0 or 1
      Sondors: P3 = 1
      P4 Handlebar Startup Mode
      P4 is handlebar startup mode. When P4 setting is 1, indicating the handlebar is under
      “non-zero startup” mode, namely, the handlebar can be effective only after startup the
      foot power assist. When P4 setting is 0, indicating the handlebar is under “zero startup”
      mode, the motor can be startup by the handlebar directly. P4 setting range is 0 or 1
      Sondors: P4 = 0
      P5 Power Monitoring Mode
      P5 is power monitoring mode, when P5 setting is 0, the power monitoring is the “real-time voltage” mode. Namely, it is the method to determine the battery capacity based on real-time battery voltage. When P5 equals to a specified parameter, the power monitoring is the “smart power” mode (this parameter is determined by the battery characteristics, ordinary 24V lithium is generally is 4-11, 36V lithium is between 5_15). P5 setting ranges from 0-40.
      9 = 24 V
      12 = 36 V
      15 = 48 V
      Sondors: 36 V -> P5 = 12
      To exit the programming mode just hold „power“ some seconds.
      After finishing P parameter settings, the P5 parameter stops flashing. Within 1 minute after stopping flashing, hold “up” and “down” for about 2 seconds to enter the C parameter setting environment.
      C1 Power Assist Sensor and Parameter Select Mode
      C1 is power assist sensor and parameter select mode.
      C1 Quantum power assist sensors or similar products
      00 5 magnet sensor
      01 8 magnet sensor
      02 10 magnet sensor
      03 12 magnet sensor
      Power assist sensors from other manufacturers
      Sondors: C1 = 02
      C2 Motor Phase Classification Coding Mode
      C2 is motor phase classification coding mode. It is served as identification parameter of different phases of the motor when using sine wave drive and the default value is 0.
      When C2 setting is 0, indicating that the used Quantum motor phase is an ordinary one.
      When the setting is a certain value, indicating a particular motor phase is used. C2 setting range is 0-7.
      Sondors: C2 = 0
      C3 Power Assist Ratio Gear Initialization Mode
      C3 is initialization mode of power assist ratio gear. The setting range is 0-8 (gear).
      When C3 setting is 0, the meter is switched on, and the power assist ratio is at gear 0. When the setting is 1, the meter is powered on and the power assist ratio is at gear 1, and so on.
      Sondors: C3 = 8
      C4 Handlebar Function Setting Mode
      C5 Controller Maximum Current Adjustment Mode
      C6 Backlight Brightness Adjustment Mode
      C7 Cruise Function Setting Mode
      Activate the Cruise Mode:  C8 Motor Operating Temperature Display Mode
      C9 Startup Password Setting Mode
      C10 Automatically Restore Default Setting Mode

      i just crashed my sondos thin. the crash broke one of my brakes: see picture.
      and now i need a replacement. most links to brakes here are to american shops. can somebody send me some links to brakes from european shops, because i don´t want to wait so long for the new ones. which specs do the brakes need to have that they would work for the sondors thin?
      ps. this post is all in lower case, because it hurts if i move my left arm

      My bike arrived yesterday! After the momentous task of unboxing, and then assembly, first step was brake adjustment. The rear brakes were only rubbing in one spot and easily fixed by bending the disc slightly. The front brakes were continuously rubbing, and thanks to the excellent videos I adjusted them with a business card and squeezing to center them. The wheel now spins freely. But as I close the caliper, the pads are grabbing on all the holes on the disk themselves and making a very disturbing clunking and grinding sound. If you spin turn the wheel at that point you can feel it grab at each hole. I repeated the process a few times with no luck on a nice smooth grip. Any ideas what needs to be adjusted? As always, a video is worth a million words:

      Here are a few pictures showing the "no power" issue caused by a brake switch being
      triggered. If you've charged your battery, inserted it correctly and have your battery
      switch turn to "on", and you confirm that the LED lights on your handlebar throttle
      illuminate, BUT you don't get power (or intermittent power) the issue is likely with your
      brake cutout switch. This bike is designed to cut off the motor when the brake levers are
      depressed, even a very small amount. This issue can be caused by brake cables with
      too much slack, creating play in the brake lever.

      In this first picture you can see a properly
      aligned brake with no slack. The lever is
      fully released and there is no gap between
      it and the housing. This is how things
      should look.

      In this second shot I have depressed the
      lever ever so slightly. I'm doing this manually,
      but this can also be caused by slack. The
      brake cable should be tight enough that this
      doesn't happen due to just being loose. A
      gap this small will cause your power to cut

      Here's what happened to me. I had things
      installed correctly, but I didn't notice that the
      brake cable itself found its way to a position
      where it kept the brake lever from fully
      releasing. Once I read that the brakes could do
      this (thanks guys) I quickly found the issue. My
      cable is now out of the way and snapped to
      other cables to keep it that way. Hope this all

      Front wheel hub is broken
      I have original sondors with suspension. But when I was biking, suddenly my front wheel got broke and I could not bike anymore. Removing the front wheel and inspecting, I could see that the cone in the front wheel hub is broken. It seems it is a very rare case and do you guys know if I can fix this? Replacing the front Tyre is extremely pricey.
