Intermittent battery problem!

[TheFatPanda]

Hi - took my e-summet out for the first time yesterday! Was having a great time and then when pedalling uphill (fairly gentle slope) the assist kept dropping out - I played around in the different modes and gears but it wouldn’t resolve - switched on-off same problem. Bike is pretty heavy the pedal uphill!!

Any advice???

Did an error code show up on the display, or the whole bike just shut down?

If the whole bike shut down then the battery mount may need adjusting, as it may not be holding the barely tightly.

Thank you - will have a look. There wasn’t an error code - it just seemed to kick-in then drop out!

But the display in the computer stayed in and was showing the assist mode

Adjusted mine yesterday on a new VR.
There was 1-2mm play at the top of the battery holder/lock end. Worth checking.
Bit of locktite on the 2 silver bolts under the black cover and you're away.

Ahh so there was power but no assistance?

If you are getting power, but no assistance, it may be that the spoke magnet needs realigning with the speed sensor on the chain stay - this is quite a common issue as if the spoke magnet has come loose it may move, and the sensor won't pick it up, meaning the motor won't supply assistance.

Brilliant - thank you will give that a go as well!
