Can a KHS SixFifty 680+ HardTail with the 2500 w controller be confgured with one of the 52v larger packs. On the site it lists the 48v 13ah. I was looking to get that bike with a 52 volt, Let me know Eric,

I am excited to get the order going.

[ykick]

At the moment 52V 13.5Ah Shark packs appear to be oos (out of stock) so my guess that option is not currently available. https://lunacycle.com/52v-panasonic-...ah-shark-pack/

If you want to put in the request once we have shark officially restocked we'll be happy to make the alterations on the listing so you can get it with 52v ga shark.

Hi,

Considering getting a BBSHD and pairing with a Motobecane 529HT.

Read this thread: https://electricbike.com/forum/forum...er-wheel-bbshd

It seems as though the BBSHD isn't designed for a 68mm BB and requires mounting to a shim, such that the knurling does not drive directly into the BB but into the Shim.

Has this issue been addressed since the post or is it still an outstanding concern?

Thanks

Hi,

Considering getting a BBSHD and pairing with a Motobecane 529HT.

We do not make recommendations about compatibility with specific models, but the standard size bbshd kit is built for use with any BSA english threaded BB shell from 68 to ~73 mm, i.e. it will work with most bicycles. Typically you shouldn't need a spacer with a 68mm bb shell if using the standard size kit, although we do include some spacers just in case you do. There are some instances where you may need a spacer with 68, such as an intrusive chainstay etc. so we can't flat out say, "you will not need to use a spacer". But it is likely you will not need any spacer, if the frame design is still the same. The current standard sized motors we have do have a 68mm sticker on them, not 73mm like the one in that person's pics.

Interesting! Good information. So is a 68mm and a 73mm BBSHD actually two different sizes, rather than all the same size? The fact that they each have different stickers seems to imply. It seems as though the issue that the previous person had may have been due to some sort of sizing mixup?

[paxtana]

Well that thread was posted over a year and a half ago, not long after the BBSHD came out. It could be that we did not have a 68 for the production run at the time, or that we hadn't settled on that axle length for what we consider standard length. Bafang actually makes several other oddball axle lengths for some reason. Nowadays we know to stick with these three and use spacers for lengths in between, which is the best balance of versatility without adding to confusion by having half a dozen axle lengths.

Ive tried to contact tne for the apocalypse scooter front forks as mine were bent and randomly sheered off! No response back from them does anyone have a link for better or original front oil dampened shocks as ive already ordered the wrong ones before.

[paxtana]

They would be the folks to talk to. Maybe try sending another email to them.

[Lemark]

paxtana do you have a direct email or person to deal with other then the ones listed on the site?

[bowhuntin]

wanting to know when the ludicrous fusion or carbon fiber will be in stock

[paxtana]

This thread's more for technical questions but from what I understand, neither of those will be available in the immediate future. Ludi fusion is always a preorder and takes months even when it can be added to cart, and I'm pretty sure we're waiting on some backordered component before we can resume taking preorders for next production run. As to carbon fiber I don't know which one you're talking about. We vary what we build a lot to keep things interesting, so generally if you can't add it to cart you'd need to choose another.

Hi Team,

I have this bike and looking to increase it speed, can you please help:

http://www.daymak.com/pages/classic/vermont48v.php

Thanks,
Absan

[commuter ebikes]

The general recipe for increasing speed is to raise the voltage. The proper way to do this is with a higher voltage battery in conjunction with a controller optimized for that voltage and a motor than can handle the resultant heat.

In your case, you already have a 48V system in place. If you ran that motor at a higher voltage, I would expect more heat than the motor is engineered to handle.

In my opinion, you need to get a new motor, controller and battery with a higher voltage. You can remove and sell your existing rear hub system OR add a mid drive or front hub system. There are considerations with regard to gearing, however. If your rear hub motor is DD, I would not proceed with adding a second sytem. If it is a geared rear hub motor on there now, you are fine.

If you have a geared motor on there now, I would add a geared front hub. Having a mid drive assist a rear hub motor is unconventional.

Thanks Commuter ebikes as cool as it sound what you said, most went over my head :( i was hoping for something easy like unplug old thing and plug new thing lol im not that savey

I love my LUNA BBS02 750 (bafang). I camped out at an area lake Saturday and had a nice ride yesterday morning (mild trails). I wanted another easy stroll on the park roads, but the Bafang C961 won't tuun on. When I push the "start" button, the display lights up, but shows no battery) and turns off immediately. I have checked and re-charged the battery and checked the connectors. Where do I start looking or what should I do.
Thanks, Stan Wilson, Dodge City, Kansas

Here for both BBSXX and battery troubleshooting - https://electricbike.com/forum/forum/knowledge-base

Female contacts on the bottom of the pack look ok? Re-tension them a bit? What does the voltage measure with DVM?

See the links above for more info....

[Swilson50]

After further testing, I got the display to come on, but it went off. This time, I heard a "click" coming from the battery or battery holder. I was able to repeat it several times, so I have emailed Luna to see what they want to do. I assume that either the battery to battery holder is arcing or something inside the battery box is arcing.

Hi. I purchased a Double Gear / Double Torque Motor currently being shipped from Luna Cycle. I'm trying to find out the size of the axle so I can order some torque arms. My last build, the universal 14mm ones I bought were junk and didn't fit the axle snuggly. I switched to a 12x10mm set from a bike shop in the UK and the cutout was too small for the axle. I was able to grind it out to the appropriate size. I would love to get the perfect one and avoid having to modfiy again. Anyone have any suggestions. Thanks!

[Sebz]

10mm at the flat spots of the axle for this motor.

This one should fit perfectly fine

https://lunacycle.com/parts/hub-motor-parts/torque-arm/

Or this one : https://lunacycle.com/torque-arm-amped-bike-style/

[commuter ebikes]

I had my local machine shop cut some D-holes in 303 SS plate. You can wait until to get the axle, precisely measure the cross section of the axle, and then have the machine shop make D-holes just a little too small, and then file them to fit tightly.

When I did this, I had the machine shop make the plate too large, and then I cut down the plate (using a chop saw and bench grinder) to fit perfectly on the frame.

[windfinder]

Will a 27.5" wheel/tire fit in the Luna Lander fork?

I apologize if this is listed somewhere. I couldn't find it.

Thanks in advance for your answer.

[Sebz]

Yes if it's not too wide.....you can even fit a regular 29er x 2.25inch

I am trying to mount a square battery into the triangle of my Jamis Dakar. The battery itself fits, but I need a bag to mount the battery.

I am looking at this bag but cannot find the dimensions. The battery I have has dimensions of 81mm thick. 324mm long, 140mm wide.

Also, what kind of security do people use with this bag? I would like to be able to lock up the bag so that someone can't unzip the bag or cut the bag and take this battery.

I saw someone use something like this to secure their bag. Might slow a thief down.

Hey, two issues...

I have a BBSHD with a Shark 52v (I asked for a 13.5 ah battery, not sure now if I have one since the Luna Cycle website says they're not out until September. I bought my kit in August). I have 100 miles on my bike and have charged it 4 or 5 times.

1. When I accelerate I sometimes hear a tapping sound, and I believe it's coming from the motor. I hit the throttle and the tapping occurs 1-2 times a second until I let off of the throttle. I'm not having any performance issues at all. I've had it up to 37 mph but generally I cruise around at about 22-25 and I never just floor it from a dead stop. I almost always get up to about 15 mph on my own power then hit the throttle so that I don't put a lot of torque on the motor. Ever heard of this?

2, After a fresh charge I'll take off and my charge indicator on my display will show 100% for a long time, like maybe 10+ miles, and when it finally starts to show less than 100% the behavior is hard to figure out. If it's showing 95% at rest, when I hit the throttle the indicator will show as little as 50% charge, then of course when I stop it goes back up near 95% again. This is fine, but when I'm down to a resting charge of 40-50% I'm in danger of it going all the way to zero when I hit the throttle, and I'm not accelerating hard. It seems like when the charge at rest shows 50% or less I have to be very careful, going really easy on the throttle and pedaling. It will often drop to close to 10% or even less, then when I stop it's back up to around 50%. Is this normal and just something I have to live with, or could there be something wrong?
