Should I Build A 52v 24ah Lithium Battery For An Ebike Build

[Brentis]

Then what about installing a mid drive on it and how hard would it be to install one such as the cyclone or a BBSHD? And no I have not, Isn't it the same thing as a normal bike but with bigger wheels? Also when I went 30+ Mph on my old ebike (Not a fat bike) I had a feeling that it was going to break or something due to how skinny the tires were in comparison to a fat bike or an actual motorcycle

cyclone will be harder to install and not be as clean as the BBSHD. There are reports the cyclone being too strong for its mounting bracket. The BBSHD also being a cleaner looking install.

No, I don't think it handles the same as a normal bike, the Dolomite in particular.
30mph on fatbike tires will use them up fast. Check some of the faster fat builds, Drunkskunk comes to mind. I seem to recall him getting 300-500 miles out of a set of rubber. Theyre just not designed for high speeds. They're meant to go slow to moderate speeds at low psi.

I think im all good, the old tires I had for my old bike wore out pretty quick and if it lasts that long, ill probably have to change them every year, shouldnt be too hard. Also should I go with a mid drive system or a hub motor?

Changing the tires isn't hard. Well, the Dolomites tire was a struggle to replace when I got a flat, but nothing too tough.Yes Fatbikes still get flats. :wink:
The issue I have is the price of quality lightweight fatbike tires vs. 26". Start investigating. That site we linked has a whole section on tires.

As to mid drive or hub you still have to give more info.

Where do you live? Does it snow a lot? Do you live in the desert? Side of a mountain? Beachfront? Prairies? American?
We need an idea of the kind of grades you climb if at all. Use mapmyride or other such programs to get an idea of the grades in your area on the routes you take.
Hub motors don't like to be bogged down for long under load, overheating is the issue.
Mid drive you can shift to the best gear to keep the motor spinning in its most efficient range.
Know that a mid drive is like a manual transmission in a car. You need to shift to a large ring to start then shift to smaller rings as speed increases. Do you have experience driving a manual? A hub is twist and go like an automatic, all be it a one speed automatic.
Was your old bike a hub motor? What type? Gotta a pic?

Do you think if your old bike had good fresh appropriate treaded rubber, that you would have saved the crash you had?
Was it your technique? Going fast, leaning way over and hitting loose sand, gravel on pavement will take a fattie out too.
A fat tire isn't going to be the end of spills.

Are you set on the Dolomite or have we convinced you to throw a few more bucks at a better Bikes Direct bike?

Hope this made sense. Still working my first cup o' joe. Not all there yet.

I live in Arizona so no snow here lol, the main reason I want a fat tire bike is because I feel safer if I go 30+ mph on a thicker tire rather than a thin tire like on a regular mountain bike. My old ebike was a hub motor (1000w) and i'm pretty sure I could handle switching gears when need be. Also I think another reason why I slid on the gravel was because the bike was top heavy (4 12v SLA batteries on a rack on the back:/) and as soon as it hit it, the front tire slid then I went with it >.<. Also won't it be harder for me to slide on gravel or something due to the size of the tire? Another reason why I want to build a fat ebike. It's also pretty much flat here, only incline would probably be to cross a bridge across the freeway lol. For the bike if there is a better quality bike that I could get thats a little bit more expensive maybe $300-$600 ill probably go for that instead. Also for some reason I can't find a 26 inch fat bike on bikesdirect.com, so if you could recommend one please tell me. I am also using lithium batteries in a triangle bag so it balances out the weight more evenly. Thinking of going with the cyclone because its cheaper but I'm trying to find an install guide first. I will mainly be going 25+ MPH when I go to school but I would like to be able to go faster on open road with no cars so another reason why I want to go with the cyclone. Also would you know if I would be able to install a banana seat for the bike? Because after school I would like to be able to have a friend go along with me places. Would a 72v battery be a good idea or stick with a 60v battery? Thanks!

 

[ArcticWolf_11]

Another thing, has anyone ever bought a battery pack from lifepo4.in ?? They sell a 72v 20ah battery with a 60a max discharge and a 72v 40ah battery with a 80a max discharge. Would 60a be enough to get the full 3000w out of the cyclone and are their battery packs any good? Thanks!

I live in Arizona so no snow here lol, the main reason I want a fat tire bike is because I feel safer if I go 30+ mph on a thicker tire rather than a thin tire like on a regular mountain bike. I don't believe this correlates. In fact I felt much safer and more stability with my first build (20" wheels/2.25" tires on a 26" wheeled MTB) than I ever did on the Dolomite. A better quality Fattie may have been different. I rode the LBS 24lbs full Carbon fattie showpiece and Wow what a difference, but that was around the warehouse, not the real world. One more thing to consider is that a motorcycle can still slid out in gravel and sand. Doesn't matter how fat your tire is if it loses traction and slides, same scenario can happen. My old ebike was a hub motor (1000w) and i'm pretty sure I could handle switching gears when need be. The BBSHD will require you to shift as a regular routine if you want it to last. The Cyclone being twice as powerful can be a lil more forgiving. Also I think another reason why I slid on the gravel was because the bike was top heavy (4 12v SLA batteries on a rack on the back:/) I hope you learned a few things with that setup. Lead is dead, more expensive in a cost comparison than Lithium and you found the easiest/worst place to place it.and as soon as it hit it, the front tire slid then I went with it >.<. Also won't it be harder for me to slide on gravel or something due to the size of the tire? Another reason why I want to build a fat ebike. I guess it all depends on the size of the gravel patch but, nope, see motorcycle example above.It's also pretty much flat here, only incline would probably be to cross a bridge across the freeway lol. Flat terrain commuter. Sounds like a perfect job for another hub motored bike, unless you plan to start hitting desert sands.For the bike if there is a better quality bike that I could get thats a little bit more expensive maybe $300-$600 ill probably go for that instead.

The Cyclone is going to require you to have a lil more mechanical aptitude to fit right reliably. Also would you know if I would be able to install a banana seat for the bike? Because after school I would like to be able to have a friend go along with me places.Anything can be done, doesn't mean you should. :wink: I wouldn't if I were you. The bike is not designed for that. Would a 72v battery be a good idea or stick with a 60v battery?BBSHD can handle 14s lithium. IIRC Cyclone goes out to 60volts so say 16s Lithium. A hub can go to 72v or higher, the more voltage the faster you'll go. Thanks!Your welcome, hope it helps. I'm half awake without coffee yet, in fact time to put on a pot.

I don't have personal experience with that company. Do you have links?
72v20ah of LiFePo4 is a big chunk of battery for a bikes triangle. 72v40ah forget it.

For the Cyclone 60v @50amps=3000watts that's more than your requirements demand.

There are many good packs out there but it's to early to make many suggestions.
But, if your going Cyclone why not one stop shop.

Edit
Luna cycles used to have a 60v triangle battery for the cyclone and Kinaye's fat hubs, but it looks like they dropped it. So forget my one stop shop idea :wink:

1. What about a fat bike going like say 35+ Mph on road/concrete, I would have assumed it would have felt safer due to the larger tires, so this isn't the case?

2. How hard would it be to get used to shifting? On my old non electric mountain bike I didn't really shift the gears unless I needed too

3. Yeah terrible idea to put the 50+lb batteries there >.<

4. Yeah I know. That was a 1 time thing me trying to cross it on the old ebike and it resulted in me falling lol

5. So should I get a hub instead? I'm still deciding which to pick because I want a bike that can go fast when I want too

6. I just got on the site and all I see is that they only have options that say 22 inch and below, unless i'm looking at the wrong thing, do they have 26 inch fat bikes?

7. I think I can manage installing it, exactly how would I remove the bottom bracket, i'v seen videos but i'm not sure if its the same for every bike

8. So what would be a good way to fit another passenger on the bike then?

9. What battery should I buy then? I want to get the maximum power out of the motor and I didn't know there were 72v hub motors lol

10. Thanks for all your help! and I just woke up too lol

Woops, copied the link wrong, here it is http://www.lifepo4.in/lifepo4.html

I hope someone with experience with this company can chime in, but I wouldn't touch them.
They use others stock photos as their own to make them look like a legit outfit. They're not alone in that behaviour. Check out the girl throwing up the peace sign at the bottom of the page. I've seen her on at least half a dozen battery sites as well as the photos of the labs and workers. Bit shady to me.

Assuming they are legit, the bigger issue is the size of those batteries. Where are you going to fit those on your frame?
Only going to work with a rear or front rack.

They have a 72v 20ah 30A lithium pack that's 8.6x6.3x5.5 inches and weighs 16.5 lbs including the charger and a 72v 20ah 60A pack that's 12.6x8.7x5.5 inches and weighs 26.5 lbs including the charger. Not sure if these are the right dimensions and weights for lithium batteries of this size but they do sound tempting. They even have a skype support line lol. Even if I do buy them I could get a triangle bag from lunacycle.

1. What about a fat bike going like say 35+ Mph on road/concrete, I would have assumed it would have felt safer due to the larger tires, so this isn't the case?
I don't know. Never done it. Wouldn't try. Check out some builds that have. Ask ?'s

2. How hard would it be to get used to shifting? On my old non electric mountain bike I didn't really shift the gears unless I needed too
That depends. Have you driven a manual tranny car? The BBSHD will not be as tolerant of not shifting than the Cyclone, but they are both crank drive motors and are meant to be shifted.

3. Yeah terrible idea to put the 50+lb batteries there >.<
Dont make that same mistake.

4. Yeah I know. That was a 1 time thing me trying to cross it on the old ebike and it resulted in me falling lol

5. So should I get a hub instead? I'm still deciding which to pick because I want a bike that can go fast when I want too
For your use I'd use a hub motor. Flat, commuter, want high speeds. That's a hubs forte.

6. I just got on the site and all I see is that they only have options that say 22 inch and below, unless i'm looking at the wrong thing, do they have 26 inch fat bikes?
Not sure why the link isn't working for you. There are about 20 26"fatties there ranging from $399 to $2200

7. I think I can manage installing it, exactly how would I remove the bottom bracket, i'v seen videos but i'm not sure if its the same for every bike
Lots of videos of BBS installs, Cyclone similar but not as refined.

8. So what would be a good way to fit another passenger on the bike then?
Buy an ebike style scooter.

9. What battery should I buy then? I want to get the maximum power out of the motor and I didn't know there were 72v hub motors lol
Hubs are not voltage limited, but the controller is. The more volts you throw at DD hub the faster it'll go. Which hub you pick will depend on how fast, how far, and how much load it has to push.

10. Thanks for all your help! and I just woke up too lol

your welcome. Give me a lil and I'll track down a hub you will like.

 

[ArcticWolf_11]

your welcome. Give me a lil and I'll track down a hub you will like.

Thanks! The more power the better, assuming I could find a battery pack for it and it doesn't break the bank lol, really wanting to spend less than $500 or so on a motor. I didn't know that hubs were not voltage limited, I always assumed that if it said 48v and you put 60v on it, it would break/fry something lol.

 

[Brentis]

Check out http://kinayems.com/Products/MongooseDolomite this is a DD hub on the Dolomite frame that meets your needs.

http://Em3ev.com offers a fatbike specific 170mm geared hub, but it's pushing its limits at 35+mph on a heavy fattie.

There are others but I'll leave you to do a lil work for yourself. Search Fatbike hub motors and builds. Though mid drive fatties seem to far out number hub motors.

All the best
Talk again soon.

 

[ArcticWolf_11]

Thanks and how sturdy is a hub motor? As my old one cracked and I used jbweld to try to fix it. Another reason why i'm leaning towards a mid drive kit, it would also be cheaper to do so too.

About as sturdy as it gets, though the odd pot metal axle and covers have failed. Pretty rare though.
Please describe how and under what circumstances did yours fail. Which make? Pics?

It cracked on the side here is a pic (sanded off the paint and the jbweld off so you could see the crack). Also not sure what happened that caused it :/

If you can live with a single speed, this Fattie will allow you to use just about any standard 135mm rear hub motor as its one of the few that still use that standard at a reasonable price.
Deadeye Monster

Edit
What brand is that motor? Is that disc brake side?

Its a motor made by AW http://www.amazon.com/48V1000W-Electric-Bicycle-Display-Conversion/dp/B00Q8JT9H2 and I wasn't able to install the disc brake that it came with because my bike couldn't fit the thing that clamps on to the disc to stop it lol. Also how fast do you think the lunacycle kit would go compared to the cyclone 3000w? I'm thinking of getting the kit you suggested with the 72v 3000w motor but it is $700+ :/

 

[ArcticWolf_11]

Also, now that I think of it. Would it be a smart idea to buy a fat cargo bike instead so I could have a passenger if I ever wanted too? Also how rare are they because the only one that I have seen is the one that lunacycle sells, $485.95 Bike frame + $389.95 cyclone 3000w + $700 or so for the lithium battery = about $1575 for the entire bike not including shipping and a front wheel ;-;.....

Edit: On second thought would I be able to just buy a deadeye monster or something then go and make a rack out of steel then weld it on to it? Or would that be a bad idea? :/

That my friend is a pretty standard kit with the exception of that odd disc brake set up. Stay away from that the second time. For what it's worth AW International is likely not the maker/manufacturer, just an American reseller. Minor point.

I realize now that you are pretty fresh to the world of ebike tech. The Luna cycle kit is a 1000w rated hub motor. That means it can safely sustain 1000 watts continuously. Hit a hill at speed or some hard acceleration and it will peak higher, say 1500-3000 watts(rough guess) but it would over heat if you used it like that for too long. So climbing long sustained steep grades, plowing through a foot of sand or snow, carrying a passenger, etc will burn it up.
Back when we talked about a hub being voltage independent, I should have clarified a few things. I've been in this ebike world a second and take for granted that I know and understand things that a newb might not.

An electric motor is wound to a certain speed known as kv. Or to simplify rpm per volt applied unloaded.
As you search out motors you will find motors rated by there kv. Some motors are slow winds(less the 10kv) some are fast winds (15kv and up) some are medium winds (10-15kv), these are just rough guesstimates to use as example.

So that 1000watts can be achieved in different ways. 24v X 40amps= 960watts, 36v X 30amps=1080watts,
48v X 20amps=960watts. The amount of voltage and the kv of the motor you use will dictate how fast you go. The amount of amperage your controller feeds it will dictate how much power you have. So for the same 10kv motor 24v will go roughly half the speed of a 48v system. The faster you go the more power you need, hence the more amperage you will draw.
The quality of your battery and its ability to supply the current you demand need to match what your motor/controller will draw at max, or you will kill them fast.

35+mph will require more than a 1000watts. Add a passenger and you need even more power.
The advantage of the Cyclone is that it can use its 3000w through the gears. So using your 3000w and your largest gear you can climb a mountain, but at a slow speed. Or you can use your smallest ring and go 35+ mph but won't have the same torque output to climb. Great for your comutte.
The 3000w hub motor I linked gives more thermal ability so you can comutte at 35 fine but it will still slow down and heat on steep hills as its still one speed. It will just last longer than the 1000w motor. Some thing I should have checked with the 3000w hub is availability, sold out till June

Confused yet?

Please ask ?'s I or others will help clear this concept up for you. I got to stop writing you before I fully wake and caffinate.

Fat cargo bikes are rare. Luna's is the only one I know of that's designed to carry a passenger. Though I've read some mixed reviews of it. I have seen a Yuba Mundo cargo bike converted to fat tires so that is one other route.

Forget adding a rack strong enough to carry a passenger on the deadeye, bad idea. The deadeye's advantage is its ability to use regular motors because of the 135mm dropouts.

Get your passenger a skateboard and a rope to pull. :wink:

Doing a lil YouTube watching this morn and looked what was recommended for me.
Think you may enjoy.

Here is the Kinaye Dolomite build I linked you to earlier.

[ArcticWolf_11]

Ah okay so it doesn't matter what the voltage and amperage is as long as it can suppy the necessary wattage to the motor as long as the controller can support it? Like 60v x 50A = 3000w or 72v x 42 = 3024w?? So a 60v 50A battery would preform the same as a 72v 42A battery? Hopefully this is all correct lol

So as long as I can properly switch gears the cyclone would be fine? The most ill probably climb is a ramp to cross a bridge that crosses the highway

What about the companion bike seat? It's about $100 and says it would support a person just fine

Why would making a custom rack and mounting it on the bike would be a bad idea? Would welding break the frame or could I just make a clamp that attatches to the sides of the bike like a clamp to secure it firmly in place?

A bike going 35+ mph isnt the safest thing in the world, going 20 while holding on to a rope on a skateboard, hit a rock, pothole, or something and you will go flying lol

Also is it possible that if it goes too fast the chain could snap/break or something?

Like 60v x 50A = 3000w or 72v x 42 = 3024w?? So a 60v 50A battery would preform the same as a 72v 42A battery? Hopefully this is all correct lol
This is not entirely correct. The 72v battery would be running the motor like 20% faster than the 60v battery. You are correct about the wattage though.
Motor, controller and battery must all be considered together when putting together a system. The battery must be capable of continuously supplying the controller the amount of volts and amps that the motor can handle.


So as long as I can properly switch gears the cyclone would be fine? The most ill probably climb is a ramp to cross a bridge that crosses the highway
The cyclone can certainly use gears to its advantage but it's not near as necessary as with the BBSHD being that it's twice as powerful. I'd still recommend a hub for your usage though. 1000w hub won't have a problem with a highway overpass. 3000w will give you the speed you want and all the hill climbing you'll need. Nothing more reliable than a DD hub either.

What about the companion bike seat? It's about $100 and says it would support a person just fine
This is for the Luna cycle Fattie? Go for it if you can afford it and like it.

Why would making a custom rack and mounting it on the bike would be a bad idea? Would welding break the frame or could I just make a clamp that attatches to the sides of the bike like a clamp to secure it firmly in place?
It would be bad on any other fattie. They were never designed to do such work. Odds are it will end badly and with lots of pain for your friend.

A bike going 35+ mph isnt the safest thing in the world, going 20 while holding on to a rope on a skateboard, hit a rock, pothole, or something and you will go flying lol
I was kidding with ya, mostly. I won't share with you the stupid things I did as a teen

Also is it possible that if it goes too fast the chain could snap/break or something?
That could certainly happen. Mid drives put lots of wear and hence maintence on a bikes drivetrain, especially at 3000watts. That's one of the trade off with the basically maintence free DD motor.

Thanks, but I mean this bike rack from this website http://www.thebikeseat.com/

Also how would I put the spokes in if I just got the bare hub? I saw that mxus 3k turbo motor for $349 and it could take voltages up to 150v lol http://kinaye-motorsports.myshopify.com/ but it does come out in june :/

Im tempted to get 2 of them lol but I do not want to wait anymore and where am I even going to get a 150v battery lol

Also do you have any idea why my hub motor cracked on my old ebike? Has something like that ever happened to you?

Interesting product. I still wouldn't trust it not to crack/bend frames, break seat post, or snap axles. Don't let me stop you though, we need Guinea pigs to test these things out.

You could have them spoke it for you, or you could learn yourself, or take it to a LBS that's willing. Forget 150v that's for the drag racers, the insane or guys with tiny peckers. Complete overkill.

Whoa! Walk before you run.

I have no idea exactly why yours cracked. It has never happened to me, but others here have had side covers crack, freewheel mounts shear off and axles snap. Chalk that upto poor manufacturing. Some Chinese companies have been known to use suspect materials such as shit pot metal.
