Hi! Brand new install here of a mid drive kit. The 1000w bbshd. I'm getting error 21 and all the cables seem to be in good shape (new) and everything is connected securely. I'm running a pugsley with an internal 8speed shimano alfine.

In addition, possibly because of error 21 my assist levels are pretty similar and the throttle seems to be kind of on or off.

Lastly, is it normal for the motor to sort of slightly stick when I have to roll the bike backwards? As in when I'm leaving home I have to roll reverse a bit.

[paxtana]

21 is a speedo sensor error, likely you need the magnet closer.

Hey, I'm looking at the Roam Fusion with the Ludicrous controller upgrade. Two questions about the ludicrous:

1. Will I be able to use it at 2500W continuous output without melting the nylon gear? Or is that only intended for short bursts like going up hills?
2. If it isn't safe to use continuously, will the controller automatically decrease the current when it gets too hot or do I have to be careful to monitor that myself?

Basically the Ludicrous speed/torque is really attractive, but I also want a reliable bike that I can ride 25+ miles a day without worrying about burning something out. Thanks!

[paxtana]

The nylon gear will be fine, it's very rare we ever see a problem with that even with Ludi.

New to the e bike scene, but really loving it. Wish I had found Luna BEFORE purchasing my ride, but it is what it is! Of course, being a natural born hot rodder, like I assume a lot of your customers are, I now have the need for MORE POWER, lol!!

I will most likely end up buying one of your radical monsters, but for time being, I want to take my current ride a bit further.

I ride pretty much 99 percent off road, have it right behind my house. Woods, trails, creeks, sand, open tall grass fields. My 2 German Shepherds accompany me,
and in the 2 weeks time I have had my "ride", lol, we have covered a bit over 300 miles! I just CANNOT stop. My area is FLAT(Texas) so hill climbs of any distance are NOT in my equation.

My "ride" does fine, front suspension, ThudBuster, 750 watt rear geared hub motor, 48V 11.6 pack. 27.5 inch FAT TIRES.............a Fat tire off road bike. AMAZING what it can do even with it's LIMITED power. She has decent torque, 25 MPH speed(enough for the off road part) and handles pretty well for a "cheap" e bike. I made a GOOD CHOICE in my 1st rider I think. I want more torque, more acceleration, and some top speed(but 25 is COOKING in my riding areas) ...............the off the line power(watts?) needs improvement, as does her climbing ability.

Im intelligent, been googling for days.......................MY HEAD HURTS!!! Been steered 20 different ways................very confused. Thought maybe HERE, I could get straight answers.

My line of thought is/was this: Current controller is 15/22.BUT testing it shows me she will only throw 740 watts to the motor , even with the 48V pack, so the controller or display unit are limiting it. I have found out THIS motor will survive somewhere around 2000 watts............SO..............

Was going to buy a 50 amp controller................a Cycle Analyst 3( believe it can CONTROL amps to motor???? set to 40 amps with it, 50 amp controller so future usage might be available) and throw around 2000 watts at it, IF C3 can adjust amperage, maybe even start at 35 amps and near 17 to 1800 at it.

I ASSUMED my 48V 11.6 Dolphin pack COULD supply this amperage..............but NOW thinking it cannot. So......................Look up specs, my pack says: 30 Amp Continuous BMS Panasonic 2900 mAh Cells......................so I GUESS IM NOT gonna throw 35 or 40 or 45 amps at my motor with this pack??????

HELP PLEASE..................be cool, lol, I will end up buying one of your 5K bikes...........................hard to RESIST after seeing THESE LIL MONSTERS!!!!


BTW...............NICE WORK on these bikes you sell.............pretty BAD ASS looking to me...................I KNOW they would just SPANK my lil "ride",
BUT, since I am in, an a "mod" NUTT ................I want to takes this lil 750 hub motor to it's limits before I move on to one of your mid drive 50 MPH beasts...................

Thanks in advance......................YOU REALLY GONNA ANSWER IN A HALF HOUR........................????? If so, probably save me from buying something else I dont need....lol

Cycle analyst can only control amps to motor if the controller has a plug for cycle analyst. Most do not.
I'm not so sure a geared hubmotor can survive 2000w, that's a lot for a geared hub. But maybe.
A 50a controller will trip the BMS on your pack, you will not be able to use the stock battery with a high current controller. You would need to replace the display, controller, and battery, as well as using compatible stuff like throttle. It's not impossible but it's kinda problematic considering it would be basically a total rebuild of the entire bike, which is typically not cost effective.

Lastly, is it normal for the motor to sort of slightly stick when I have to roll the bike backwards? As in when I'm leaving home I have to roll reverse a bit.

Yes this is normal.

Was so excited to try out my bike that I used it for the first time without charging up to full. Am charging up to full now. Is there a way to know if I have somehow damaged the battery pack or cells? Am charging it using 1 amp setting

[paxtana]

Foldersunite No you're fine, the battery has has a battery management system built into it to prevent discharging it far enough to do damage. Not to say that I would encourage regularly draining it to the point where you reach low voltage cutoff. This causes "dendrites" to form over time and isn't good for the pack, but it's not a big deal. Basically every lithium battery in existence is in a slow decline from the moment it leaves the factory, only question is whether you are speeding up that degradation process. The BMS prevents the worst of it, you can take this even further by not taking it below 20% and only hitting 100% once every month or two for balancing, rest of the time charging to ~80%. Check out the battery knowledge base on the forum for more details.

On degradation, please see this video for what I mean when I say dendrites:

Need to know if there is any fix on front fat coil suspension bike...there is play on the left suspension tube whenever I put on the front brake.

[paxtana]

Not too sure, might want to ask your local bike shop since it sounds like the kinda thing someone would need to see in person to evaluate.

[Brattmjones]

Changing hall sensors on Cyclone 3000w needed to know if i have to remove the stator from the can to pick out old sensors thank you.

[paxtana]

Yes, you would. It would be very difficult without damaging the motor given the force needed to be exerted..

[Brattmjones]

Want to add xt90 to my Luna 1000w hub motor and would like to know the best way to do it

[HIGHVOLTAGE]

Are you using any connectors right now currently or do you have it hard wired/crimped? If so, you basically just have to cut the power +/- wire and solder them to XT90's. If you live near any hobby shops that deal with R/C drones, they usually will be able to offer soldering services for like $10 and will even usually have XT90's on hand so you don't even have to purchase them. That's how I got my cradle connectors changed out for my battery.

[paxtana]

Here's a video for you on basics of wiring:

[zrxjet]

Thank you for your response . I do understand what your saying about cost effectiveness. I thought that if I bought these things, controller, battery, and C3 display, they could all be ported over to a "better" donor at a later time. I did not look at it as a purchase to stay on this bike forever.

I now understand my problems with the battery packs. I have read about the BMS now, and realize my pack at 30a will "trip" if I plug it to a high amp controller.

I have read about the need for a C3 output. The unit I am looking at has one. DOES THAT MEAN, I COULD control the amperage to the motor, and NOT "trip" a battery? I.E Get good controller, use the C3 to set amps to say 28 or so, under my 30a continuous rating on my battery??? Attempt throwing like 1500 watts at it??? Are the higher end controllers(this one like 180 bucks!) adjustable themselves, like the C3??? The ones Im looking at say programmable.

I saw you 40 amp controller just now. Does it have a C3 output on it??? If not, you have one that does? You have what I need to do this??? A good controller that will suit my needs now, and in the future, the C3 display unit, and a great battery pack. I know you have the packs covered.

Would I want to go 60V or 72V. I assume going 72V I would need a really good controller, and C3 or other means to keep amperage in check.

Would be NICE to buy it all in one place.................you guys have what I need ????

Thanks

[paxtana]

Yes that would work if the controller is programmable. Presumably you could use a cycle analyst or just program it directly. I would probably just program directly since cycle analyst is not user friendly, and you can get more intuitive battery info from other products.

No the 40A cyclone controller does not have cycle analyst input. It's also made for mid drives, not to say it wouldn't work with hubmotors but it can be fairly difficult matching hall motor wiring combinations if you're not experienced with that sort of thing.

By cost effectiveness I mean that since parts are largely specialized to the application you need, there's a good chance you would want other parts if doing a build from the ground up. Such as a battery that more closely matches the triangle of a donor bike, or a full kit that already includes these other parts.

[commuter ebikes]

Once I learned how to do what I wanted to do, I found my Cycle Analyst V3 to be user friendly.

[Brattmjones]

Thank you not using anything right now haven't built battery yet I would really like to make a adaptor with the xt90 on one end and the matching connector for the controller side does Luna carry the female connector for the 25a contorller that comes with the 1000w hub kit

[Enickols12]

Hi, I am looking at building an e-bike using a Bafang BBS02, but that battery that I have planned would be 36v. I have found some sources that say that the motor can run on 36v, but the lunacycle site only has 48v and 58v batteries listed with it.

Thanks

[HIGHVOLTAGE]

There are some units specially modified for 36v capability by certain vendors but unfortunately we don't offer that capability at this time.

Will the Electric Enduro Motorcycle seat fit a Vector Typhoon frame? Where can I find the dimensions for the Cyclone 7500 motor? Best Regards

[paxtana]

Please see below for a picture of the dimensions.
I do not know if Enduro seat will fit vector, I would assume you could make it work with enough effort.

[LuckySchwinning]

Thank you for the pic exactly what i needed. Can you give me the bolt hole measurements from the enduro seat, Pls? I'm willing to make it work if its close. I really like the way the enduro seat has that grab bar for hooking up tow ropes :)

[Moontimber]

I have a Terratrike Rover recumbent trike. I modified it to use an 8 speed 26" wheel in the back. I am thinking about getting an electric rear wheel. I can't have a tire bigger than 26 X 1.5 or things start to rub. What wheels or motors can I get that are compatible with an 8 speed setup?

I want something easy to remove when I want to pedal unpowered.

[commuter ebikes]

Have you considered the mid drive options? If you "want something easy to remove", a rear hub motor does not satisfy this requirement when you (1) repair a flat tire, (2) replace a worn out rear tire, or (3) need to remove the rear wheel for any other reason.

If you choose a rear hub motor, the width of the hub motor will compete for space with the freewheel. Choose a narrow hub motor and you can fit a tall freewheel, but this may come at a cost of motor heat. Choose a large hub motor and heat won't be a problem, but this will not allow enough room for more than even a 3-speed freewheel.
