I don't understand the question ?
what is the best e-bike kit??

Well that depends on a few things really such as the batteries ability to deliver the power under load.
For instance if the 20ah battery can only provide 20 amps or 1C, acceleration will be slow compared to a 10ah battery that can supply 50 amps + or 5C
That really effects acceleration and hill climbing, top speed on level ground would be much the same!
For lower powered applications a geared hub makes the most sense because you will get more torque from it over a direct drive, and it will be far easier to pedal. In fact peddling a geared hub even a little up a steep hill can really reduce your energy consumption, it works much better than a direct drive, so you and the geared hub help eachother.

A (amps)=torque
V (volts)=torque and speed
Ah (amp hours)=how long the battery will run before being discharged
C rate= how many amps your pack can provide. IOW's ah x C rate=max amps. A 10ah 30C lipo pack provides up to 300A
There are some variances to consider, like voltage sag under load, but that basically sums it up. Just make sure your battery can provide the max A of your controller and you'll be good.

parmenps, YES, that controller with the ping battery will work. BUT Wait just a little bit longer and you will get it to winter, Because when your dealing with China it takes at least 4 weeks to get your kit and we are already in the middle of June.
All jokes aside, I have that specific battery and it has served me well since 2009. I know that Ping states on the site that the battery is rated for 500w, I have been pushing 1200w and I ride an average of 14km a day on an Direct Drive motor.
Do yourself a favor and PULL THE TRIGGER! get the kit before you miss this season of riding.
Good luck

That looks like the controller that came with my motor kit. If it is, it draws 30A, which would be pushing the output of that battery, possibly popping bms overload breaker. A 10ah 2C battery is only really good for a 20A or less controller. You need a 15ah for a 30A controller. BTW, if that's a 30A controller, you'll pull up to ~1800W from the battery.parmenps said:

haha that was funny. Just for some perspective on Swedish weather, right now we are having a high of 53 Fahrenheit and at night around 45. The summer has not come, and when it comes it will be over before we know it.
wesnewell, I respectfully disagree, I can confirm the 48v 10ah ping will take a constant 30amp discharge. My controller is an Infenion programmed to 30amp discharge as confirmed by my wattmeter with Regen and it works no prob. I have even discussed this with ping because I was going to try to order a V.3 battery with higher discharge and he said that the 48v 10ah V2.5 can handle it but he can not guarantee that you get the 1500+ cycles. But why would you want a battery longer than like 4 years?
The 15ah ping battery is a better battery I do not contest that but I don't like is over a $100 more expensive, bigger, harder to put in triangle and weigh alot more, I know a friend of mine has one.
By the time the 10ah is dust if this guy, if he is still into ebikes he will want to move on to LIPO's.
