Is that a direct drive motor kit? If so, why do you want that?

More than likely a D/D drive , can't say have seen any 1kw geared hubs the nearest I've seen is the Q128h. Generally those D/D kits are very heavy and have a high speed winding with low torque so not very good for its climbing ability. Several on here have bought similsr kits but as yet we have seen no real world reports of decent rides and the kits ability backed up by some data.
Edit;
Just seen the specs posted as expected 470rpm you will be iucky to get that to climb a speed hump ;). Before you waste money on that kit, ideally a test ride on a bike fitted with one would be a good idea up a hill.

It's would be best if you could tell us all what you are trying to achieve. Direct drive is rarely the correct answer.

We need to know:

How far, how fast, how heavy. How hilly, how handy, how fit.

If you answer these questions you will have a much better chance of getting the correct kit.

I wouldn't bother with that kit. You have front disk brakes. DD motors struggle with torque(grunt). If it has any it's not good with front forks unless they are steel.
The speed will make you stand out and risk your driving licence.
If it is 1kw it would flatten even a 17ah battery in half an hour.
And 36 volt systems are more common. So better price and availability.

you can get hub drives with massive grunt and top speed just not those types and speed drains a batt fast so will need a big un see 2nd vid.

Thanks for all the replies I don't live in particular hilly city and need it to do about 10 miles a day maximum just to work and back I am not exactly physically fit at the moment will be pedaling quite a lot also just a little push to help when I am on a long uphill.

You don't say how much you weigh, so it's difficult to give an answer, but I agree with others, a DD kit is probably the wrong way to go.

If I were you, I'd be looking for a rear wheel kit, with a geared hub motor (Bafang/8fun SWX or similar) and a downtube mounted battery of about 10Ah at 36v. Panda bikes sell all kinds of kits in UK.

I don't know how long that BOSS will last doing 10 miles a day though, so be prepared to move the kit to another bike at some point. It would be worth keeping an eye out for a second hand bike locally. Something like a Trek, GT or specialized.
