Can a BBHSD that's designed for 100mm BB be adapted to a bike with 68-73mm BB? If so, do you sell the adapter?

[HIGHVOLTAGE]

This is currently not possible right now unfortunately due to lack of adaptors. I'm sure someone is working on it though *wink wink*

[fleadope]

Trying to add a bafang mid-drive to a road bike with drop bars, and the original thumb throttle doesn't fit. Outside dia of bars = 24mm, inside dia of the throttle is 22mm.

You have a different looking throttle on the site: https://lunacycle.com/bafang-bbshd-a...humb-throttle/

The page redirects to a page on this board, but I can't find any info on the specs; can you advise me?

Thanks.

I’d like to install a BBSHD motor on a chopper style frame that has a one-piece/American/astabula bottom bracket shell (first two pics). I found an American to JIS/BSA BB shell adapter (see third pic) that should work and allow the motor housing to clear the BB shell – does this look like it will work?

Also, with the BB shell adapter on, I expect the total width to be around 75-76mm. I’m thinking I should get the fat version of the BBSHD (73-100mm), correct?

I also have another frame that I might use in the future that has a 120mm wide BB shell (JIS/BSA) – if I bought the extra fat version of the BBSHD, could I also make that work on the frame with the 75-76mm BB shell?

Thanks,
Noah

You don't want to go wider unless you have to.
Yeah it'll work with extra parts and possible fabrication but it's more effort and it puts the pedals farther away from the frame than you may prefer and often makes it lopsided.

Yes the eccentric adapter will work with bbshd. Might want to go with the Luna version as it will give you better clearance.

https://lunacycle.com/american-style-eccentric-bb-to-bsa-adapter/

It's okay to go with standard bbshd and go couple millimeters over, that extra axle length is just used by the black lockring which acts as a jam nut, you can use loctite instead and go without that part entirely, this gains you an extra 3-4mm.

But yes if you are set on going with 100mm that will work, though you will need extra spacers, or possibly an alternate mount bracket such as bsb-1 if you dislike how all spacers need to be typically placed on drive side which can make it lopsided.

So for the luna 5000 carbon fiber fat, the sale on it is $0.05? Really? Or is it a typo?

[HIGHVOLTAGE]

Likely website error. The bike isn't even in stock and available for sale.

[paxtana]

That model is unavailable, sorry. It was built off of the Luna cyclone deluxe which we no longer stock. Clicking any options causes it to do page validation and check stock levels, and it will show out of stock at this point.

[CAMatt]

I am trying to order the Bafang programming cable and entered my email as requested but have not heard anything in weeks. Are they that backordered?

[HIGHVOLTAGE]

Yeah, they're coming. We haven't discontinued them or anything.

[AZguy]

If you'd like to DIY one it's quite easy and I'll send you links to the two parts if you like (I've posted them in other threads)

[CAMatt]

Thanks HV.

[quantumcloud509]

What bms did Luna build the 72v24ah packs with?

[HIGHVOLTAGE]

That information isn't currently available to the public right now. I also don't think we've ever had a 24ah 72v pack?? Maybe I'm wrong on that. Any 20S BMS will do though.

[noahp99]

I see that the 52v Mighty Mini 30Q 6ah battery pack is no longer available. Will it be coming back and, if so, how long before it's available again?

Also, is the 52V PANASONIC 11.5AH CARBON SHARK PACK a good backup choice for the BBSHD? I think the BBSHD controller is limited to 30A and I'm trying to keep my costs down, so would like to save the $150 on the Shark pack vs the Wolf pack.
Thanks

[HIGHVOLTAGE]

It will be coming back eventually. It's quite a popular pack. No dates right now though but I can't imagine it'll be any longer than a few months. And yeah the 11.5ah PF pack can handle 30 amps just fine. You'll just get a little less range out of it than a 13.5ah GA pack.

Too be honest I'd save up a little more and spring for that Wolf Pack. The 30Q cells have great lifespan and low voltage sag with decent range. They are a popular choice among E-bike enthusiasts. GA cells are for maximum range options but suffers in other aspects and PF cells are for inexpensive options to keep your pricing down, but it's a fairly mediocre cell overall.

I am building an ebike to do work commutes all paved roads and going onto sidewalks a lot

8 miles a day for 5 days a week in all weather

plan on going 30mph -no suspension cyclocross bike -38c tubeless tires

Judging by my shopping list below, is there anything you think I should add?

suspension seat post maybe?




Is there any tool or product I am missing that would prevent a successful installation or be good for my intended use of the ebike.


BBSHD mid drive kit
full color display
thumb throttle plus spare
luna wrench hand
luna sockets and torx wrench
tektro ebrake front
regular disc hydraulic brake back
lekkie bbshd cranks
a good chain
luna tool kit
wire crimpers
programming cable
42t eclipse chainring
torx wrench and socket



triangle battery
case waterproof
smart charger



dielectric grease
silicon grease (to water proof stuff)

[HIGHVOLTAGE]

Generally looks all good. Make sure you order most of this stuff as a kit and not separately to make sure you at least have the bare minimums to run the kit in-case you forgot anything. Not sure if you need both the Wrench Hand and the Luna Torx Wrench though. They both serve the same purpose. I would only get the Torx Wrench if you plan on doing multiple installations or plan on regularly removing your motor for maintenance/swapping bikes.

[Joe Remi]

Torque wrench..Torx is a different thing. I agree with High Voltage that you don't need both torque and hand wrenches, and the hand one is workable, but I'll throw my support stronger towards the torque-and-sockets even for a single build. My first build with the hand wrench came loose a couple times, plus it's just kind of annoying to work with because of close proximity to frame and motor when you're tightening the nuts. The torque wrench comes with the values needed to tighten correctly printed on the handle, and it's just SO nice to work with. I think it's well worth the extra cash.

[HIGHVOLTAGE]

Yeah, Joe raises a good point. My first installation was a a loose one so probably best to just go with the Torque Wrench for a rock solid installation with no chance of loosening.

[Brentiea]

Purchase two bikes Crusher 2&3
the computer on the C-2 keeps shutting down???? I have to disconnect the battery for re-Bot . Help

[HIGHVOLTAGE]

What voltage is it shutting down at? What does it say on the display?

What do the XT90 connectors look like on the battery? Any scorching marks? Make sure to check the bottom tube frame where the cabling routes into. Does it look like the battery is crushing any of the cabling? If the straps on the battery aren't properly secure, it can potentially crush the harness cable. I have this bike so I had to learn this the hard way hahaha.

Also, obligatory "Has it is been ridden in the rain/snow at all?" question. Corrosion can sometimes be an issue if the bike is persistently ridden in snowy/rainy conditions or hosed off with garden hose.

[sambar]

Hi, i have a weird thing happening to my 2nd anniversary BBS02 kit. I start a ride with a full battery and after a few miles on PAS the motor dies as soon as i stop pedaling for a second. No error on the display, no throttle is working. Then i have to wait a few minutes and the motor runs again and keeps running but only as long i keep pedaling.
(no break sensors and working gear sensor) Any suggestions?
Ahh, PAS level 0 suddenly feels like 1...

[paxtana]

I would try reprogramming the controller or unplug all the wires from controller>motor. Worst case scenario swap out the controller for a new one.

Thank you paxtana!

How do you turn off the headlight on the Sur-Ron bike ?

I saw on "https://electricbike.com/forum/forum/knowledge-base/bikes-aa/55116-sur-ron-documentation"

Light
Rotate the knob on light to turn it on/off

Where is this knob ? Is it on the headlight ?

[paxtana]

Yes unless they changed something it is right behind the light, a convex rear that rotates

[girlpower100]

My BBSHD throws sparks around when I try to connect the battery (52-58 volts).
Measured the plus/minus contacts going down to the motor and it reads 1.7 ohms.
Is this normal?
Any ideas why the sparks fly?

[paxtana]

The controller has capacitors for power conditioning. It sparks because power is flooding into those caps.

If using a hardcase there is no need for connector between cradle/controller so you can cut it off and hardwire it. If using a softpack it has xt90-s antispark connectors which a matching connector can go on controller side.

In theory you could swap out the Andersons on a hardcase and stock controller for xt90-s as well. We sell the set on our site. Though in practice having a connector there at all is a bit redundant.

[AlanKilian]

Where can I find the manual for the controller that comes with the 7500Watt Cyclone?

I'd like to get a headstart on wiring before the kit arrives.

[HIGHVOLTAGE]

Cyclones don't come with manuals. They are fairly advanced level DIY kits for experienced builders. Although most of plugs should be generally Plug N Play.

We have an entire Cyclone forum full of resources if you wanna get a headstart:

https://electricbike.com/forum/forum/kits/cyclone-mid-drives

[noahp99]

Any idea when the Cyclone 3000W kit will be available again?
Thanks

[paxtana]

About a week.

[Trbutt]

Yes unless they changed something it is right behind the light, a convex rear that rotates

This is the light that came with my Sur-ron:

I cannot see this convex rear knob, the only attachment is the cable that screws into the back of the light.

[paxtana]

Hmm..looks like latest model changed it :/
You'd probably have to wire in a switch like our remote to turn light off on latest model as it appears to be always on with this version.
