Troubleshooting

This section provides troubleshooting steps for your OHM Electric Bike: 

The system does not turn on

Check the battery and make sure that it is charged. The battery must be correctly inserted onto the docking station and the lock must be completely closed. Also check that all connectors of the wiring harness are properly engaged, and the console is inserted properly. If the problem persists, contact an authorized dealer.

The system can be turned on but there is no assist – POWER PROT appears on console screen

Check all connections, in particular that the cables running from the battery to the motor are properly connected (with the system turned off). Turn the system on. If the problem persists, contact an authorized dealer.

The system is continuously in Generate mode

When the propulsion system is continuously in Generate mode and cannot be switched back to assist mode by pushing the + key, the problem most likely lies with the brake switch that is located under the brake lever. In this case try to “repair” the system by turning it off and then on again. If that does not solve the problem, you can temporarily bypass it by removing the plug-in connection from the console to the brake switch.

WARNING

If you bypass the brake switch you also disable regenerative braking, in doing so your BionX system will not provide any additional braking. We recommend that you contact a dealer as soon as possible.

The motor is not as powerful after a repair or service

Tighten the nuts of the rear axle to the specified torque (40Nm/30lb-ft); check that the axle slot is facing in the direction of 6 o’clock. If the problem persists, contact an authorized dealer.

The battery state-of-charge display on the console does not show “full” after a complete charging procedure

Make sure that you have followed all of the instructions for the charging procedure. Let the battery cool off for a few hours and charge it again. If the gauge still does not indicate a full charge, let the battery cool again, fully deplete the battery and charge it again. If the problem persists, contact an authorized dealer.

The throttle lever offers no response

Check the throttle connections. Next, attempt to calibrate the throttle, simultaneously hold the On/Off and – buttons until a countdown begins at the top of the console screen. Fully depress the throttle lever and release a few times during the countdown.

The system will not turn on after storage

48V BionX batteries are now equipped with “Deep Sleep” mode, a new function that preserves battery energy. To activate a battery that has entered Deep Sleep mode, connect it to the 26V BionX power supply. If the battery is removed from the system when doing so, allow the battery 5 minutes until it turns off before re-installing. A series of 5 beeps will indicate the battery has shut off and it is safe to install again.
