1000 km is 620 miles so maybe a little thin but the salt just eats bike parts so if part of that time is with salt it may not be that bad. Quick math are you going through 2 drives per year? So one of them isn't being exposed to salt? That does seem like more wear than many others are experiencing.

What brands / models have you been using? All the same or have you tried different stuff? Cheap seems to be no good for E bikes and expensive doesn't seem to be any better than the mid grade stuff so most of us are ending up in the middle. The expensive stuff that is about saving weight seems to be the worst for E bikes, I have read many reports of broken chains and cassettes with that stuff.

BTW your display appears to still have the protective shipping film on it.

--> Ha ha ! I know :-)

The Box Components seems to offer interesting gears, I could give it a chance if though they are saying: "Not Intended for Ebike Use" :-/

I've sent them an email to advice on a ebike friendly groupset :-)

There are specific versions on their site that are for ebike use. Not that it really matters IMO, I have used one of their 8s versions for years with no issue and that definitely does not say for ebike use. Bottom line is that their core values are one of not skimping on durability for minor weight savings, which definitely makes sense for our uses.

Yeah ok I understand:

One of their sales person actually answered me and confirmed what you are stating basically , see below:

"Hi Etienne,

All of our EBike specific drivetrains are great for the Ebike application.

Please not the difference between our Ebike and standard drivetrains are that all our Ebike drivetrains come with a single shift shifter and a cassette with a small cog of 12T.

Box Two Prime 9 X-wide Ebike
Box Three Prime 9 X-wide Ebike
Box Three Prime 9 Wide Ebike

Box Four 8sp Wide Ebike

Depending on the terrain that you are going to be riding and will help you with deciding which drivetrain suits you best.

If you have any questions please let me know.

Take care,

I recently purchased my new Surron black edition. While going for my ride today, I noticed that the horn has stopped working. Do you guys have any suggestions on what may be the problem.

Is this an appropriate way to bleed hydraulic bike brakes? See below.

Because my no-name brakes don't fit any of the fill nipples in my kit, I did the following.

-left the system closed except for the port on the brake lever, and put some fluid in the bleed funnel.
-removed the brake pads and put the stop-block in.
-repeatedly squeezed the brake lever until no more air came out and no more fluid went in.
-the whole time, flicking the hose in order to encourage air to come up.

Is there anything wrong with doing it this way? It seems like a hell of a lot less effort than using the whole kit. Just put the bleed funnel in with some fluid and pump the brakes until the air is gone.

Seems like my X1 never saw any loctite. Thought I got them all but still managed to lose one half of the threaded set that holds the seat dropper lever together. Any thoughts on how to get another? Thanks

After a recent ride the check engine light would come on after 2 minutes of powering on. Wiith error code 15H. The bike would run for about 5 minutes after the light came on and then power itself off.
Any help would be greatly appreciated.

**zmarkjam** · 08-23-2021, 08:17 PM

On that display (750c) 15H error code is a speed sensor error. On other displays the speed sensor error code is 21. With the system on and the rear wheel spinning, check to see that the speed sensor flashes (red light), and that the display is registering speed. If neither is happening, make sure the spoke magnet is lined up and passing close to the sensor and check again. If the speed sensor isn't working (light won't flash and display won't register speed) your auto shutoff in the display is probably set to 5 minutes and powering the system down. You may be able to keep the system on by turning off the shutdown timer in the display settings. You won't know your speed but the system won't shut down.

What would be the best bike for off road trails and bumpy terrain/adverse weather conditions (mud, rain, maybe snow)? I think I'm looking at the Luna Cycle Apollo, the X1 Enduro, or the KHS 500 but I'm not sure how to interpret the differences between these three (I'm trying to stay away from the Sur Ron, which would probably be the best choice for the intended use, because I would still like the option of using local bike paths and trails). Is there anywhere to read a comprehensive comparison of the differences? Does one of them stand out as the best for off road use?

after my first ride on my new setup my 52V mini charger is seemingly unable to charge my luna wolfpack v2 battery.

Both LED indicators flash every second or so accompanied by an audible click LED1 is red, LED2 is green.

This youtube video shows probably the same issue i am encountering: https://www.youtube.com/watch?v=jXqE...VDFTRs&index=2

In the comments it describes an adapter that can be used to stop this, however, my charger was not supplied with an adapter.

My major concern is that this will damage my battery and therefore i am unable to ride my new bike until this is resolved.

Is it safe to continue using the charger in this state?

Hello, hope all is well. I am sorry I am not sure if I am posting this in the right spot.
I have a db primary chain conversion kit but the big sprocket is backwards according to the instructions form the company. The bike works but it is really loud. I know the primary chain is louder then the belt but this is really loud. I had the same kit on another Sur Ron and it was nothing like this sound. I only rode the bike around a few blocks and then decided to check and that’s when I figured out it was backwards. It is going to get fixed on Monday so the reason I am here is I was supposed to go riding today but now I do not feel safe riding the bike. Could the sprocket being backwards make it louder? Does anyone know why the sprocket should go the other way? I also emailed the company but I don’t think I will hear back till monday. Also could someone please tell me the proper tension for the primary chain?
Any help would be great.
Thank you!

Hello, I have a Luna X1 Enduro and was riding yesterday. I've got about 250 miles on the bike so far.

As I was riding I heard a pop and the chain went loose. I checked and the lower arm of the derailleur is pretty slack now. It doesn't return to a taught position pointing away from the crankset as it used to.

I watched a few videos on youtube and had a look at the spring and I do see a wear mark that looks like maybe the spring slipped inside the barrel but after pulling it apart and making sure both ends of the spring are seated in their slots it is still very slack. Can you tell me if that spring has to be wound in some way? Is there some other obvious problem I am overlooking? If you can describe what to do to fix it I can fix it myself. Thanks for the help!

Part 5 in this picture is the spring I am talking about.

I recently bought a used sur ron(took a chance) that’s been sitting for a couple months, the seller said that the battery was fine just dead, once I got it and tried to charge it,it will bout take a charge!…I tried the low voltage deal with turning the charger in then off 40+ times with 2 different chargers and still nothing! Reads 0%, any ideas or is the battery trash?

**cpoole** · 09-22-2021, 09:58 PM

Are the controller settings for the Bafang Ultra on Apollo also
configurable using a programming cable? I’ve been enjoying my new Apollo for a few weeks and wanted to know if
that is something we can play with.

thanks
