Video Instructions - Controller, Sensor, Bearing etc maintenance

[Ravi Kempaiah]

This is BH's Youtube channel and they have some basic instructional videos about changing the bearing, sensor adjustment, Controller replacement etc.

Might be useful for DIY times in the garage or when you don't have any dealer nearby.

Awesome! Thanks for sharing Ravi, I had stumbled across this a while back and the content is pretty good. It's neat that they offer a resource like this to help people optimize and maintain the bikes. I recently shot a couple of videos with the founder of Optibike covering batteries and motors... I'll try to get those up soon!

Here is another useful BH related video. Removing the rear wheel from a Neo Xtrem.

And another useful one.

If there is any loose connection with the battery, it might not display the correct charge level. Here is a quick vid describing what might be wrong.

Sadly I couldn't scan this, but here is a photo to explain further details in relation to the torque sensor.



[edit] touched up the attachment and typed out for easier reading below:

Adjust the torque sensor - RDS

The innacurate adjustment of the torque sensor may cause incorrect functions in the motor assistance. For these cases, the controller
software includes some additional securities to avoid any related risk. It is necessary to know how the torque sensor works in order to adjust
it if any malfunction appears.

The torque sensor reads the tension of the chain, which is proportional to the torque generated by the user on the pedal. It is mounted in
the right-hand side rear drop out and it is joined to the frame by three M6 screws.

It is not necessary to remove the torque sensor to remove the rear wheel. The rear wheel can be easily removed, same as in a standard
bicycle. Besides, the torque sensor is totally sealed and can be cleaned with water for a correct performance.

In case the torque sensor is removed, please apply the correct torque to the screws. An incorrectly applied torque may generate a malfunction of the ebike. See diagram for torque settings.

I made a discovery today when refitting the wheel to the BH.

Follow the first video carefully and don't remove the nut and torque arm from the brake caliper side of the axle. I have always removed both nuts, but leaving 'both' of them on the rear axle makes life very much easier. I stupidly hadn't noticed this detail from the video.

As you slide the rear wheel back in, you can use the brake torque arm to guide the wheel in. I can now remove and re install the rear wheel in under four minutes.

I also added the following in another thread, that the plug joining the cable has an arrow on each side of the connector. To make life easier, put a dab of Tipex/correction fluid onto the arrows, which then makes life easier in relation to lining the connector block back up again.

Thanks Eddie, your tips will no doubt help many of us avoid some hassels in the future. I just wish, as you and I have discussed, we could get a torque value for those wheel bolts. I would be willing to get a " crows foot " for my torque wrench for the right side wheel bolt, if I knew the value.

 

[EddieJ]

I'll be brave and email my local dealer later to ask.

Hey Dave and Eddie, aren't there a couple of Easy Motion guys here on the forum? Can't we just private message them to get an answer? If you struggle reaching anyone just message me and I'll reach out to my advertising contact Stateside. She isn't as knowledgeable about technical stuff so it's a last resort but I'd love to get this figured out with you.

 

[Dave]

Yes Court there are some EM guys. I will try Mark at Len's and see what info I can get, I'm sure it's in the service manual.

 

[Dave]

Here is what Mark from Len's electric bikes emailed me concerning my question about torque values:

I did not find specific torque for Emotion, but many other bands with same axle and bolt sizes show 30-40nm for torque specs.

This is in reference to the rear axle bolts. I would have guessed somewhere in that range.

I'm thinking that I may need to adjust the "clearance" when installing my Thudbuster (27.2mm) into the 31.6mm seatpost tube of the Neo Volt. Can anyone figure out what the tech is doing starting at about 0:24 of this video?

 

[EddieJ]

It's hard to tell, but it looks as though he might have put a shim in for adjustment?

Yes, I think you're right ... but not sure if it is a metal washer or rubber. I also unsuccessfully tried to rotate the silver bar at 1:33, but it seems wedged in tight, so I didn't force it. I may have to McGuyver a washer or strip (of 2.2mm thickness) around the silver bar. Open to any suggestions, though.
