Most motor kits are available with a28 inch wheel option. Maybe contact the seller or check other listings from the seller.

is dis motor a goot wan (the 1000w version) and which battery is the best
The motor kit would be good enough, the motor is fine for a starter kit, the controller is ok. But it won't be fully plug and play. The battery harness is very poor.
That was my first kit 3 years ago, I got the 48V 20ah LiFeP04 battery, but it was 15 kgs, too heavy for the rear rack of a bicycle!
Their current LiFeP04 duct tape batteries are just as heavy and way too bulky! The duct tape one I got from them was sold as 20ah but only gave 15ah. They do seem to have higher continuous discharge rates, but I would still stay away form them!
Their Limn204 Battery 10ah weighs only 4 kgs, decent discharge rate for your kit. You might get away with 12-15 miles no pedal full throttle. If you can charge at your destination that would be better. I have no Idea about the life expectancy of those batteries!

This one would probably be lighter again, but would have the least life but is cheaper.

You may have to make up a battery connection to the controller yourself.
I can't advise you what to do I'm afraid,Maybe someone that has bought those batteries can advise you better.
But I wouldn't tough the duct tape LiFeP04 batteries, I certainly wouldn't buy one again. Apart from giving me 15 ah out of 20, it's just way too big!
Try get the cycle analyst if your budget allows, it's very useful for telling you the exact amount of charge left in your battery, and how many amps you are pulling, and for counting the cycles on the battery.

or I better take lipo packs.
I do it right the first time
I'm afraid on your budget there really isn't much you can do. Buying all the kit together is expensive for the first time.
LiPo of about 15-20 ah will still cost because you have to buy the charging equipment. My sole reason for buying it was for small size and as little weight as I could get away with, I wanted to have fun too so I needed the high discharge rates LiPo could give me. Cycle life is not so important for me.
What would really save you is if you can charge at your destination ?

Yeah that setup should be fine, but you realise you won't get the 15 miles or so at full speed ? You will need to charge at your destination.
How good are you at soldering and wiring ? I'm not sure the wiring harness will survive or plug directly into the battery.
That kit works out at 210 USD , check what it is including shipping.I would strongly recommend this kit from cell-man

His battery would also be cheaper and have a little more range, but it is a far better battery. You could also solder the shunt in the controller for more power.

Add up the total cost between cell-man's kits and the conhismotor and the other battery, ask cell-man what the cheapest shipping is, but the cell-man kit would be far better quality.

There wouldn't be much difference, but the golden motor battery harness will fail, where cell-man won't ship anything that's of poor quality!
cell-man's battery would be far better than the gm battery + cell-man will ensure that the battery can connect to the controller easily without you having to modify anything. It would also be better if you want to run high power in the future, but you may have to get the higher amp bms if you want to run higher than 30 amps as you will most certainly want to.
I would also ask him for the 12 fet controller, then you are all set for a mac 8T kit when you get more money!
It's a lot to think about, but I would save for a better kit to begin with rather than spend money on a battery and controller that isn't so good, but come to think of it. I would wait until I could spend the money on the mac 8T kit and battery, I guarantee you wouldn't regret it.
Maybe you might want more than 30 mph in the future and that's where you would probably want to go LiPo but you can learn all about it in the mean time!
If you decide on the mac, then wait until the new clutches are available!

The best ebike kit is E+ hands down.
E+ motor/controller build in is for sure one of the finest money can buy.
Except you temporarly cannot buy it from manufacturer, all sold out

About 50kph, but you'll need to go easy on the throttle on takeoff with that battery since it's limited to 20A.

sorry
I know it's tough, but you can't ask us to make up your mind for you!
Go with your gut feeling, spend what you can afford, if you can't make your own cable harness, learn. If you don't know how to crimp or solder connectors, learn. Sure you will break stuff, do stupid things but that's what this hobby is all about, it's fun, interesting and will give you endless miles of smiles!
We can help and advise you, but everyone will have their own opinions neither one is right or wrong. And you will learn this as you go along. You can always save for something better. But one thing for sure even if your first kit can only take you 10 miles and only go to 35 kph the first time you ride it you will smile!
Let us know how you get on and take a few pics!
Best of luck

You want a battery pack capable of putting out at least 30A without straining it too much. So for a 10ah pack it needs to be rated for at least 3C discharge. Most lifepo4 packs are rated for 2C max, so you'd want at least a 15 ah pack at 2C. This is why I went with lipo from the start. Even the cheapest lipo you can buy is at least 10C and most is 15-50C, so you don't have to worry about about the amp draw with even a 5ah pack. I recently built a 10ah 20C 12s lipo pack for $130. That's rated for a 200A output. The 1000W kit I bought has a 30A controller, meaning it draws 30A max.parmenps said:

That battery should be fine as long as the specifications are correct!
It's risky buying from unknown sources, I would get a 20 ah ping if that battery costs around the same.
You might be able to get a battery rack for that battery where you can lock the battery.

How appropriate! Last nite I got in a hurry, hooked up the wrong wire and burned up a hall sensor
Even though I think I can fix it in time, I've ordered two more motors, but the wait is going to kill me.
Last week, I learned not to run a 12v PS on a hyperion @ 2C.
I'm not sure which will come first, expert status[or at least accomplished] or a depleted bank account.
It's a good thing that I'm single.
Despite my extensive reading, there things I guess I just need to learn for myself.
As a Lipo noob, I had ordered various connectors mostly crimp-on, pre-made sub harrnesses, the wrong size shink-fit and now realize, that for me, the way to go is quality 4 mm bullets[soldered] and 14 ga. silicone and make it all. I think I must have gotten clone Andersons, for they just won't stay connected.
Anyhow, I'll get there.

PS Scorp. I would just copy your build, but the rear drop outs on my beloved Rocky Mountain Edge just won't support a 1500 Watt motor. The alum. chain stay is delicate to say the least, with no where to afix any kind of serious torque arm. Maybe build number two.
But I think I have a plan to do something interesting that will keep me contented for a while.
