How To Make an Electric Bike Part 6 www.comcycle-usa.com

[spectrospirit]

Magnets are simply amazing, but you did know that these magnets also can give electricity?

I saw a magnet wheel with generator attached spinning up to 6000 rpm and it managed to squeeze out 100 volts quite easily.

I'm currently stocking up to do some experiments on magnets and multiple configurations and i suspect this could easily replace any batteries of today.

I think i'm pretty close to not being dependent on batteries, in theory that is.

Everyone want to save money so i'll try do just that

[TheGandeloft]

Did anyone actualy make a bike using this? :P

[doubletriplerainbow]

You can get a lot of High quality E-bike parts from Busettii electric bikes in LA. They ahve the really long range and higher speed stuff. I ride a Busettii Bike and it gets about 55 miles of riding on one charge unless I ride it at the top speed of 27 mph then it only gets about 35 miles per charge. Rainbow

[ComCycleUSA]

@doubletriplerainbow I don't know for sure, but BMC is an OEM supplier to many eBike makers (like Currie, for example). I don't think anyone OEMs these particular motors, but I could be wrong about that.

[RO55M4C]

how fast does this bike go on a flat straight?

[AcumenDown]

Where might i be able to buy these parts? By these parts i mean the Electric Hub Motor, Throttle, Controller, and Lithium Polymer Battery. I'd really like to undergo a project similar to this, hopefully in a cost-effective way.

[meravei13]

i want to put this on me bike LOL

[rspoons]

What about 2 kits for 1 bike, 1 electric motor per wheel. It would create a heap of power and still be fairly light.

[arashogfar]

what if it rains?

[ComCycleUSA]

@arashogfar These are not waterproof, but they can handle a little wet. For real rain riding, you need to waterproof the bike.

[arashogfar]

@ComCycleUSA okay thank you very much!

[rtex95]

Very good videos, however i cant find it for sale, do you still sell it ? Thanks

[dirtdadx]

@rtex95 We only sell the accessories now

[Dave51262]

Very good video series, however, I do not see any kits for sale on your website. Have you discontinued selling them? I just see various parts that would not make up a complete kit.

[dirtdadx]

@Dave51262 We sell only bike accessories now.

[maria271011]

I have a Busettii Electric Bike and I love it ,Ride it everyday ! I wanna try the new vortex bike too!

[64jcl]

How safe are these electric bike kits when it rains? I live in a part where we have 200+ days of rain every year but is seriously considering an "electrical upgrade".

[PownedEntertainment]

exelent idea : )

[rainbowdragon1215]

I have seen other E-kits like this also, and wanted to ask most I have seen lets you choose either the front, or the back wheel, does yours only do the back wheel ?

[ComCycleUSA]

@rainbowdragon1215 BMC makes a front wheel version too. We have concluded that only very low power motors work on the front of a bike. These motors have too much torque and tear apart most forks, even rigid steel forks, in the long run. The rear of the bike is much better at supporting the weight and power of the motor.

[rainbowdragon1215]

Does this kit work on Chainless Bicycle's ?

[ComCycleUSA]

@rainbowdragon1215 Yes, I have build up a bike with no chain with this motor. Of course, you cannot add pedal power and you end up with more like an electric scooter, but it does work.

[rsmithlal]

@rainbowdragon1215 I'd imagine.. From the look of things this setup is pretty much chain independent!

[evildoctorbluetooth]

will the controller charge the battery at certain times, IE, going down hill?

could dynamic breaking be used?

[ComCycleUSA]

@evildoctorbluetooth That is commonly referred to as "regen".

This controller cant do regen, but we sell the compatible Infineon model that can, both braking regen and full time regen.

Also, this motor features a clutch that allows the motor to freewheel to a stop when the bike is coasting, so the motor cannot do regen.

This design makes the bike feel more like a bicycle. It coasts and descends freely. Regen on a bike adds coasting drag. Both styles have their fans.

[runisle]

Really helpful video !

[MrGolfTee]

top speed?

[ComCycleUSA]

@MrGolfTee With 36V about 23-25mph. With 48V about 29-31mph

[avirankatz]

What does the controller do?

Can't I simply connect the battery to the electric motor?

[ComCycleUSA]

@avirankatz It provide throttle control efficiently. If you just hook up a motor to a battery, it just runs full speed. If you just put a resistor in line, it burns off lots of power. Modern controllers us Pulse Wave Modulation (PWM) curtuitry and Mosfet transistors to switch the power at different frequencies to vary motor speeds with minimal losses.

[wealthfinder192]

how long will this run before needing recharge? If you want to know at what speed then can yuo give me an example at low speed, average speed and top speed thanks.

[ComCycleUSA]

This depends on the capacity of the battery measured in Kilowatt-Hours. This battery is 36V 10AH or 360 Kilowatt-Hours. I am presuming neutral conditions, meaning no wind or hills. Other factors matter like rider weight, how much stopping/starting you do, and how much pedal power you add.

At a low speed of 12mph you can probably get 15-18 miles from a battery like this. At a top speed of about 25mph you can probably get 5-10 miles. Average would be between the two for speed and distance.

[donwinkey]

way better project than a pyramid car rofl if you havent heard about "pyramid car" yet, you better use youtube right now to get the right image about it

[MrJetjoe]

i built a electric scooter with 1000wat 48volt moter running 36volts and 26aph batteries and the thing runs longer than 8 hours and 4.70 gearing goes 42mph just though you would like to know that is posable

[nictii]

Dennis thanks for these tutorials... very well done and I learnt alot!

[kevykev38]

Nice idea and great fun. But upon checking your site out ..I found the kits and components to be very over priced. I have found similar components on another site that were much much cheaper. Why is that?

[ComCycleUSA]

@kevykev38 Like anything there is a wide variety of prices and qualities of solutions. The quality of batteries, controllers, the wheel build, etc., can all cause the price of the kit to vary a lot. We actually sell a lot of our kits to people who have those low priced kits that fall apart after a few months.

[bendawo]

no sry

video is in progress

actually it is not that hard to built such an alu-box

i used wood for the stabilisation

it works very fine

I will post my video here as soon as it is done^^

[animator909]

hey wait i thought that a motor had positive and negative not those other names you called those two leads that came out from the motor

[ComCycleUSA]

@animator909 Brushed motors have two leads. This is a brushless motor, it has a total of 8 leads. 3 leads are the phase wires, and the other 5 are for the hall sensors. Nearly all brushless motors work this way. There is a new generation starting to come out that is brushless and does not use hall sensors. Such motors only have 3 phase wires. Like I mention somewhere, this stuff is changing pretty fast right now.
