e-bike wheel on steroids

[rockinjoxx]

Wheres the playing card for the FAP FAP FAP FAP FAP FAP?!?!?

[raydiofolk]

ever thought about building a car with these motors?

can you brake electricaly and feed the bateries?

[circuitdotlt]

@raydiofolk Did thout about it. Due to high unsprung mass, it is way better to mount motor(s) on the frame and transfer motion via shafts.

All motors do have regenerative braking, mine does too. Its all about motor controller or it's software, to be exact.

[ImJaanek]

attach this wheel to the bike and usea a long cable to drive with it, it would be kind a fun! :D

[circuitdotlt]

@ImJaanek clearly you have no idea what today's batteries can do.

Nice Video That You Share , So Very Nice Thanks You e-bike wheel on steroids

[MACHINEIRON]

Very nice. If there was some way to perfectly balance the wheel it would be even better.

[akrobatictiholubi]

je to velmi  hezké video

[Ultranothing]

Stick your finger in there

[ElectricAvenuesIRE]

I have this motor in a 20" rim. I will run it at 24s {72v nominal} and around 100 Amps. Cannot wait. It will rip hard.

[vistigioful]

It was probably spinning at 100mph.

[Thaaps]

Lol it did a wheelie :D

[RoweroMacka]

thes motors - fasttest ones like 5303 or 404 or 405 are for smaller wheels 16" 20". what is the point using it at 26" ?

[circuitdotlt]

@RoweroMacka point is in getting high top speed. With improved cooling, of cause.

[RoweroMacka]

@circuitdotlt ok, so what battery will you fit in it ? i guess this will ride on roads?

[circuitdotlt]

@RoweroMacka Yes, this is going on the road. This one, to be exact:

i.imgur. com/M3nNd.jpg

24 inch wheel, 80V A123 20Ah battery. Top speed on flat should be ~ 85 km/h. Onboard 40-minute (2.4kW) charger. 35W HID lamp, all other lamps/horn to be street-legal. Pedals only for testing, will remove them later.

[RoweroMacka]

@circuitdotlt ok i got it. nice piece of work was done here :)

but...i do not like it. it is heavy, it costs, too heavy to go to forest.

i guess 7 kg motor, 24 kg battery, 4 kg front suspension, 5 kg frame?

i once had 48V20Ah LiFe + C'lyte 406 and after 3 years of fun i decided next e-bikes must be light

now i got 250W geared 2.4 kg + 48V10Ah Headway. and i like that idea, i can go to forest and enjoy a lot.

If i was you :) i would simply buy Enduro motor:)

good luck friend

[circuitdotlt]

@RoweroMacka Battery is 12 kg, not 24. Total weight wil be ~45-50kg. For power/weight ratio, it's no longer a bicycle. Look at this like at a motorcycle, and a damn light one. Motorcycles start at like 80kg.

250W is wayyy too weak for me. It's OK as an assist for going shopping etc, but not for motor-only transportation.

[RoweroMacka]

@circuitdotlt something is wrong,

48V20Ah headway = 12,5 kg (including simple protection made of rubber)

80V20Ah should be at least 20kg.

i assume you using 26650 2.3 Ah A123 cells?

is it 24s9p ? 216 cells

or wait a minute, are you using prismatic pouch cells? 15Ah or 20Ah ? from Cellman ?

[circuitdotlt]

@RoweroMacka :) I use 20Ah prismatic A123. 0.480kg/cell. Not from cellman, directly from manufacturer. But I do have some for sale, got them from cellman.

24 pcs with my micro BMS is 12 kg. Headways are crap. Had many tested. 2,4kW charger is 3 kg.

[RoweroMacka]

@circuitdotlt i use headways since 2009, from two different produces, first one was crap, many cells unbalanced at start, bms not working good etc, now my new distributor got very nice headway cells and already assembled battery packs as i wish. maybe you weren't lucky with your headways just like i was at 2009. they are so easy to make pack.

but i do know what these 20Ah cells from cellman can do. i have read full test thread on endless. but price is so high. headways are 12.5$

[circuitdotlt]

@RoweroMacka $12.5 for what capacity? A123s go for $30 per 20Ah. Not that expensive, only $1.5/Ah. HW cells cost similar. But yes, they are easier to deal with.

Yes, headways I tested were from ~2009. Now I do have a "new" one, got it as a free sample directly from manufacturer (chinese family) at eCarTec exhibition in Germany, a couple months ago. Did some testing: performance below +10°C is just terrible. Did not do more tests though.

[RoweroMacka]

@circuitdotlt i simply can't afford it, need to make bike for myself, for my girl-Maria, for 9 year old kid (yes he rides electric:D) then i want to buy suspension like RS Revelation or Pike, decent frame like "Kona coilair" or "Author A-rh" or felt redemption (currently got author and felt frames.) add 3 motors - 300$, add 3 batteries 36+36+24 and then you got a lot of cash :( and i earn not much

[MongooseFreeRider]

Nice Tyres The Holy Rollers

[bkunal88]

Ok what's your point then ???

[marknano]

That's just normal speed for an electric bike without a load (person).

[coycoy75basualdo]

Hello im building an electric bike and i was wondering if you can tell me wich battery is better the lithium ion or Nimh Nickel metal

[circuitdotlt]

@coycoy75basualdo LiFePO4 with no doubt.

[RoweroMacka]

@coycoy75basualdo nimh got memory effect, and it lasts 2 years. lifepo4 is like 6-10 years in theory. and lifepo4 is smaller then nimh.

but lifepo4 is fragile when we talk about heat, in 40 celcius degree it degrades fast. also in theory, no one measured it. it changes so fast. go go china develop super nuclear cells :D

[xxTatsuyaKun94xx]

OMG, thats very fast! if my city's metropolitan trains use this motors, it would go faster than they go now LOL, and sounds like the newest subway trains

[Artevaldo]

Taip ir supratau, geriau nurodyk linka į savo blogą, tada ir kitiems aiškiau bus, šaunus projektėlis ;)

[Artevaldo]

Sveikas, tai tu pirkai toki rata is eco-led ir perdariai?

[circuitdotlt]

@Artevaldo nepirkau, tai kitoks motoras.

[Demoman42]

Sveikas. Kur galima gauti toki rata su el. motoru, kaip siame vid. ?

[circuitdotlt]

@Demoman42 labas.

eco-led.lt

[Demoman42]

@circuitdotlt Dekui :]

[Glassakis]

what is the point of doing that?

[StuntBiker14]

burnout that!

[yurijm]

What kind of motor are you using? And how do you control it?

Thanks!

[circuitdotlt]

@yurijm This is a three phase Crystalyte x5303 BLDC motor. It is controlled with intended Crystalyte controller and twist throttle.

[yurijm]

@circuitdotlt

Thanks for the answer!

I'm trying to build a similar project but with a single phase motor and DIY controller! But having some difficulties =)

[circuitdotlt]

@yurijm By single phase you mean a simple brushed DC motor? In this case the controller should be very simple: only one transistor is needed if reversing and regenerative braking is not a necessity. Just feed it with current-limited PWM proportional to throttle. Three phase controllers are much more complex, as they need a lot of trigonometrical computing power and complex algorithms. If you are interested, please look at my other videos, you might find something interesting there.

[punchas19]

ant "steroidu" xDD

[auryzzz]

Kokios galios šis variklis? 1kW?

[circuitdotlt]

10 kW bus.

[circuitdotlt]

That is about 115 km/h.
