Amateur E-Bike concern

[Horizons]

Well i'm new around here as also in the matter of e bike and research so i will try to explain in this section my thoughts about making a bike electric and pls fell free to reply.
So, i have ended somehow in a 1500W Motorized Kit (CY1500A) 80kph from cyclone-tw 3 chainwheel Kit wich can speed up to 80 km/h with controller and can give maybe 20-30 km range.
But the problem is that the site says for the specific product that (controller will burn if overload more than 30 secs) and thats because controller has a limitation 650W~1200W.
This is where i have to ask for your help cause if it is a problem an overoad and a burn at the end then it seems i have to find for 1500w the right controller...

1500W geared motor without controller from http://www.cyclone-tw.com plus (Cooling Fin for motor 9pcs , 3 pcs chainwheel freewheel crank set with 158mm Axle , 3 tools , 68 links chain)

Controller 72V 1500w from http://www.google.gr/url?sa=t&source=web&ct=res&cd=1&ved=0CAcQFjAA&url=http%3A%2F%2Fcgi.ebay.com.au%2F72V-1500W-Brushless-Speed-Controller-for-Electric-Bikes_W0QQitemZ200419422119QQcmdZViewItemQQimsxZ20091219%3FIMSfp%3DTL091219204001r3406&rct=j&q=72v+1500w+controller&ei=_dtMS9C0D9DH_gbOlP2fDg&usg=AFQjCNEjOPc1rXUtpRC6BFS9MsLif5HFbw
(Don't know if it the right one or if there is one much better in quality and spec)Pls give some referral here if someone knows.

Thumb throttle - missing cause http://www.cyclone-tw.com seems don't sell it as a single part.(I have asked them in case of selling it as a single)
Where it is possible to find one in 72V maybe?
I have found only here but it is only 48V http://www.electricrider.com/crystalyte/x-t148.htm

Battery from http://www.pingbattery.com/servlet/the-17/48V-30AH-V2.5-LiFePO4/Detail but i do prefer http://www.pingbattery.com/servlet/the-21/60V-30AH-V2.5-LiFePO4/Detail because i need mileage and autonomy.
And finally a home charger.


So i need a 72V 1500w reliable controller a gemmy thumb throttle in 72V (don't know if it is ok also with 48v).


P.s Has anyone info of what this http://www.cyclone-tw.com/pas.htm is?

Has anyone the idea of charging the bike on the go with something like that http://www.opticsplanet.net/brunton-solaris-cigs-foldable-solar-power.html or http://www.growandmake.com/62-watt-solar-energy-kit-solo-15?
I mean in case of a long distance coverage haw anyone look after this section?



Thanks for the hospitality and sorry for the long message

Dear horizons, welcome.

PS Has anyone info of what this http://www.cyclone-tw.com/pas.htm is?

It is a "Pedal Assist Sensor". If you decide to use one of these, they act as the throttle, but the motor only gets power if you are pedalling. If you want to use a hand throttle, you do not need a PAS.

Thanks for the info and welcome note spinningmagnets

The Cyclone system you are looking at is very powerful. The throttle and controller changes the amps that are going to the motor. The voltage to the motor is always the same as the battery voltage. If you are carrying a heavy load up a steep hill you will have to use the throttle to send many amps to the motor, and then the motor and controller will start to get very warm.

750W is equal to one-Horse-Power (HP), One HP is very good for one person and light cargo. If you have two people on the bicycle or heavy cargo, 1,000 watts is better (1-1/3 HP). A 1200W controller is very powerful, are the hills where you live very steep? Where do you live and what will you use this bicycle for?

The standard controller does it's job reliably if used with a correctly geared motor. The problem is that Plug&Play Cyclone 1000W kits (nowadays "1500W" according to Cyclone ) are not geared down enough, and hence the warning listed on their webpage about "controller will burn if overload more than 30 secs", which is Cyclone’s poor explanation of a usage limitation due to poor kit design.
The issue is that unassuming customers buy these kits and often bolt them onto 26" wheeled bicycles. With a 6T motor sprocket driving a 44T chainring that’s a 7.33 reduction to the cranks/BB. The customer then thinks that when pedalling at his/her natural pedal cadence (~60>75RPM) that the motor and controller will be happy doing their job just fine, afterall that is what the kit's marketing suggests right? WRONG!
Under these circumstances the motor is spinning at only 440RPM>550RPM which is about ~30/35% efficient according to the dynometer chart. This is unsustainable to both the motor and the controller. Both heat up quickly and if the temperature sensors don't trip in or are un-calibrated (it seems they often are) then out comes the magic smoke. Most kits will survive if the motor is only loaded at low RPM for a short time whilst accelerating from a standstill and if the selected gear denies pedalling (keeping the motor RPM higher). However under continuous high loading at low speeds or in the wrong gear (gears that allow pedalling), the controller will inevitably blow once the thermal mass of the heatsink is swamped.
So without Cyclone advertising it, the current non-planetary Cyclone kits will only be reliable on bicycles that can't be effectively pedal assisted. 20” wheeled bicycles make things a bit easier due to the higher wheel RPM for a given speed, but as GGoodrum has stated in the past, the pedals are still effectively useless as an assist.
What Cyclone should do is start offering direct drive non-planetary motor kits that drive a large sprocket mounted next to a BMX freewheel on a Nuvinci/Internal hub. They do sell these components individually, but they don't yet offer a complete kit and most customers aren’t cluey enough to see the advantages of this setup over the standard kit.

At first i have to thank you for the time and effort to pay attention to answer and guideline about this forthcoming e-bike.

The use will be mainly for transfering to my job at long distance (about 75 km to and fro) and saving some fuel as the most people targeting in here.
The road is the classic asphalt wich of course has the classic up and downs (not such very steep).
Off road and steep i don't think will be such often or whatever cause i don't want to endorse the motor or whole set up....As i said before asphalt transpotation mainly and i really want to try on a speedy (up to 70-80kph) set up.

This concept is a thinking about a transportation wich will help me in any occasion or instance (run out of money , gas charges) of having problem to move fast with free energy.

This is why i'm thinking of getting a grid like this EBS100P8 100W E-Bike Portable Solar Charging Station http://www.innergypower.com/ebike_charging.php if i decide to make a long trip with bike but it seems to be really big and heavy



@ boostjuice
Really appreciate your cue mate.

I believe the motor on the 500W and 650W Cyclone kits are the same motor. The difference is that the 650W motor has a separate controller that can be placed in the open air to help it stay cooler when it is pumping many amps to the motor. The 500W motor has the controller inside the same body to make the system very easy to install on the bike, and it also looks less messy.

If you use full throttle to make your travel very easy with no pedaling, the battery will run out of power soon. If you use 1/2 throttle you may think that you can travel twice as far, but at half throttle you can travel about 3 times farther because at full throttle, more of the battery power is being turned into heat instead of spinning the wheel.

For very long travel, pedal with your feet as much as possible, use half throttle unless you really need full throttle power (sometimes you need max power for a minute). Sealed Lead Acid (SLA) batteries are heavy and big, and they should only be discharged to 1/2 capacity. SLA is an acceptable starter battery to save money for a short journey.

The Ping batteries are well-regarded, many purchasers are happy with them. I do not know if that Cyclone kit you want works well at 60V, but a 30aH size is very big and will provide many miles. I believe many people have used the Cyclone kits at 36V or at 48V. You should research other Cyclone users to see what voltage will give you the results you want.
