[luap321]

i would like 250w rear hub motor in a 29" wheel to take a 11 casset
i would like to use KT controller i would buy a kit or just wheel
not sure what size battery for 10miles eachway everyday
kt controller is what it has to have we will have a few ebikes in the family
an im keeping to kt so if one goes wrong i can swop bits around an if one is B E R
it will become a doner
i have seen hubs on the internet but would prefer a wheel

No one sells only hubs built in to rims in the UK.

Nearly all Bafang hubs/wheels will be from China, unless something comes up on ebay.
11t cassette no, one will have to use a 10t cassette on a std splined hub carrier.

A built wheel is usally exp and adds considerably to p&p form china so most of us always buy bare hubs and build oue own wheels or one can find a wheelbuilder to do it for you.

If the need is for 20 miles in flatish terrain and one wants to keep the battery light then 6 or 7ah will do in 2p config using very good cells in low PAS.
For my 2p configs I use one battery 6ah 12s2p 44v with LG hg2 cells and another I use 8.4ah 12s2p 44v with Molicel p42a cells. Both being top rated cells with 20+ amp cell rating.
The latter battery is mainly used for medium to heavy towing of a trailer with 24 miles range.

Small battery use depends on rider input and terrain to get low miles out of a small battery.

bike has 11speed cassette 11-46 sunrace an the chain is a kmcx11 dirailer is shimano slx shadow plus ,none of it means any thing to me but if i put a 10 speed casset on it will it work with the currant set up also he has shifters that finger an thumb type i assume when opperated they move a set amount to the spacing of the sprockets on the back is it the same for 10 and 11 speed so if i set the travel limit on the derailer so the chain didnt come off ether end of the cassette will be set up or do i need to fit 10 speed shifters ? i was hopping for him to be able to take the battery off an swop rear wheel if he had a fault and be able to use it like a normal bike until i could look at it

are bafang hubs wider than other hubs as other hubs except 11 speed

You are correct, it is the 12 spd eagles and so forth that use a different spline carrier.
