eBay vs magic or smart pie kits

They do but you need to lower the motor kV normally too to chase down amps...take an rc helicopter for example... They use brushless also( ac motor) switched by the the DC speed controller to ac..same as these bikes....so a 11.1 lipo pack..(3s). Motor kV of say 3000...turning the rotor at whatever speed it does...drawing 20amps....okay so far?
If he doubles his voltage to 22.2 he can use a motor with half the kV (1500) and probably turn it the same speed at nearly half the amp draw..extending his duration with the same mah packs......make sense?

oh! oh! ken.. sounds like your be hanging around around with Luke soon enough. or put that motor hub on the front and the morini back in the frame where it belongs! oop's i might get banned from e-bike sec. good luck and i knew it was only time before your need for speed got to ya bro. dennis

You know me too well but I'm not in Luke's league! lol
I'm going to wait to see what's up Dean's sleeve before I upgrading.
I'm pretty happy with what I've got. It's not fast but super quiet and fun as heck. Next project is the Mid Class cruiser just so I can hang out and get some track time with the boys.

when i first started riding mine like you i started looking at every option out thier. batteries, motors you name it. however after i while i stopped looking, i am actually really happy with what i have, its fun and reliable and i ride it every day

yep electric is the future... the older i get i'm starting to think about a good way to hook up a bicycle and a pacemaker... just a thought.

When I look at the Magic Pie kits at Bikeberry, most of them say they only go 10 or 12 mph.

Can anyone provide real world speeds for the Magic Pie with the various wattage hubs and battery voltages?

Thanks,

Michael

they must be talking 24 volts or something, the magic pie 3 with 48 volts 26 to 29 mph with 36v 17 to 21 mph. I have both and that is the speeds I am getting
smart pie 48v 20 to 24 mph 36v 14 to 18mph

"eBike Speed: 25kph/24V, 33kph/36V and 45kph/48V (Based on 26" rim, 80kg rider)"

Every ride I do is GPS and on flat ground my bike with 24" wheels will do 24 mph and my other bike with 26" wheels will go 28 mph. Both use 48 volt batteries. However you will notice a drop off in speed when the battery life is 25% or less.

My results are similar with an MP2. The seller was optimistic on the speed claiming 31mph with a 48v battery. In reality its hits 30+ briefly with a freshly charged 55v battery(59v off the charger). Once the charges settles it will top at 28- 29 and cruise nicely at 25-26. My 9C I bought in a cheap kit off ebay has equal performance at the same voltages I havent added the ammeter yet to the new bike with the MP2, it may be a tad more efficient. I honestly like the 9C as well as or maybe a bit more than the MP2. The GM controller is nice being programable, but it cuts the battery out if voltage is over 60v. The 55v battery charged to 4.15/cell reaches around 63v, so Im only charged to 3.9/cell@59v. Greatly reduced capacity at that voltage. Strangely the cheapy 6fet controller that came with the 9C will happily accept 63v. Figured it would smoke it, but hasnt yet. Have a 63v controller on the way as well as a 60v charger. Summation: the cheap 9C is a good motor.
