BionX Does Not Turn On

When your BionX doesn't turn on, there are only a few possible issues. The first thing to determine is whether your battery has a charge.

First Step - Determine BionX Battery Voltage

Once you know your battery voltage, choose from the option below that best describes you:

  1. My battery voltage is over 17 volts.

  2. My battery voltage is less than 17 volts.

  3. My battery voltage is 0.

  4. My battery touch port lights up green or orange or red.

  5. My battery touch port does not light up at all.


1 or 4 - Battery has voltage greater than 17V or Battery touch port lights up (red/amber/green)
If your battery has voltage but the system wont turn on it's likely there is a connection issue.

Next Step - follow these instructions to check BionX connections.


2 or 5 - Battery voltage below 17V or Battery touch port unresponsive
If your battery's voltage is very low it may be below the minimum needed to power on your BionX. In this case the charger will not work either and you have to raise the battery voltage manually before it can be recognized the BionX or the charger. Once you've done this you'll be able to use the BionX charger to charge the battery normally.

Next Step - you need to try to recover your low voltage battery.

If that fails, proceed to step "C", detailed below.


3 - Battery voltage reads as 0
If your battery shows zero voltage or the "touch port" (in the case of 48V systems) does not light up and you've already tried to try to recover a low voltage battery, there are a two possibilities:

  1. Cells are fully discharged = dead battery
  2. Internal fuse is blown (see below)
If you just dusted off your bike after a winter without riding, it is more likely that the battery died due to lack of maintenance than from a blown fuse. As it states in the manual, your BionX battery should be charged at least every 3 months during storage. In addition, a blown fuse will almost always correspond with an event, for example:
  • You were riding and all of a sudden the bike stopped working...
  • You were sliding the battery onto the bracket and there was a spark or popping sound...
  • You forgot to power down the BionX before disconnecting some part of the wiring harness... etc.
BionX battery fuses do not blow without a reason. A blown fuse indicates there is a problem elsewhere in your kit and the fuse blew to prevent collateral damage to the battery. So if you do suspect you have a blown fuse we recommend that you check for motor resistance to determine whether a blown motor caused the battery fuse to blow. If you do not find motor resistance it is unlikely that the battery fuse is blown. It is more likely that you ran the battery down to empty or left it in storage without charging it.

Solutions:

  1. If you haven't already done so, try to recover your BionX battery at home. In case this works you can save a lot of time and money in shipping and repair or purchasing a new battery.
  2. If you are within your warranty period the best solution in both cases is to return the battery (and motor if it is found to have an issue) to your dealer so it can be sent to BionX for repair or replacement.
  3. If you are out of your warranty period you should still send your battery (and motor if it is found to have an issue) to BionX for repair. Or you could buy a new BionX battery/motor. Or, if you are very handy and understand how to safely work with electronics, you could open up the battery to check the internal fuse.
Note: We would only recommend opening a battery as a last resort if you are out of your warranty period.
