Hey, i want to make ebike like this man have on youtube https://www.youtube.com/watch?v=1DS_6VjKQGY

Need your opinion.

Motor and all kit from cyclone-tw.com for 529 USD

48-72V super 3000W 13T freewheel 8kw max +105 km/h @ 72V ( 48T,44T,24T) super crazy big motors 5.5 kg without gear box with 3KW 48-72V ( max input voltage 88V) 120A continue 350A max cyclone controllers throttle 48-72V no LED light with B.B. style bracket

i will buy battery from here http://www.bmsbattery.com/packs/531-48v-10ah-38120-lifepo4-battery-16-cells-ebike-battery-pack.html 72V15AH 40152 LIFEPO4 BATTERY

maybe who can calculate how much available range? That guy in comment writing about 50 km, is this true?

Your range will be very much dependant on how you ride it, have a play with the simulator to how speed effects battery range.
I would expect a nice conversion with good condition chain and sprockets etc and good tyre pressures, no hard starts or hills with gentle pedal assist could return upto 100km at 25kmh or 25km at 100kmh from a 72v 15ah pack. Yes the variance in economy covers a wider range than internal combustion engine powered vehicles. So there is no way to calculate an accurate range.

The motor kit you have mentioned is a bit over the top for the bicycle drive train, while the Cyclone kits can work well that one is not just pushing the boundaries of the bikes drive system but probably well beyond what it is long term capable of handling.

Also the company you have selected to supply the battery do not have the best reputation on here, do some research!

Simulator; http://www.ebikes.ca/tools/simulator.html find a motor to use in the list that has similar power for comparison to the cyclone. Maybe the Clyte 5304? which will make that power.

There is a cyclone conversion on my first project below, only a 900w kit though which worked well at the 1350w limit I imposed on it with the CA.

Go for it! I have the same kit, but I bought mine in January - since then it seems the controller has been beefed up in the kit. The Kelly controller and the drive sprocket are different. The new controller is better and the drive sprocket is larger, preventing chordal noise. However, the reduction from motor to wheel is less.

I am modifying my drive train to make it quieter. I wish mine had this controller though.
