If he isn't tackling big hills I think the Q100h would be a good choice. Get the sine wave controller to go with it and you will be amazed at how smooth and quiet it is.
Contact BMSB about compatibility and specify that you want throttle control.
Their shipping is sky high so think about what spares or parts for another project you might need and order all at once.
As i understand case 02 has built in 18A sine wave controller that should work just fine with Q100h or Q128C right?
BMSB costumer suport really do not know much about how thing work, they just know what they have on stock...that is why i am counting on you guys here that really know everything about ebike...thanks again

Why not keep the current motor (not broken or worn out?) and just get 36V controller and battery to run the motor a little faster?

It can be as easy as going to Home Depot and buying a 36V battery used with mowers and trimmers, or you can order an ebike battery from Justin at www.ebikes.ca
If 25kph was his previous speed on 24V, then you'd buy 24V battery. But if he wasnt going that fast previously, then go with a 36V battery pack, and keep the same controller.
Seems to me that you'd want new. More money that way. Whats wrong with the current setup? Just dead battery, or dead battery AND not enough speed.
Hmmm, yes we could try new 36V battery with an old motor and see how it works...old batteries were 24V and he had problems going even 15 kph so 36V with 18A should increase speed to about 20 kph i think. He wants to ride 20-25 kph.
but just in case... we will order a new motor too, it will look "cleaner", it is smaller, lighter, faster, probably more eficient...and shipping is the same with or without motor so it is cheaper to order all together rather than just the motor later...
We really do not know anything about old motor (rpm, gears, sensors) and old controller (amperage, square, sine) just another reason to buy whole kit.
We will surely try new battery with old motor and if it works fine...great even simpler solution and we can still change motor later if needed.
