He wants 10 miles each way with minimum effort. I think the 36v Yose kit would be a bit weak for that. He really needs a 48v 250w kit, but I don't believe Yose does one. It's what i said - you can't have everything.
Think about buying a Yose power need help guys

Something close to that , after 10 hour shift don’t want to be peddling hard just want least effort as possible getting home , but still peddle but not ghost peddling , the journey from work nearly 7 mile straight long road . So just relax peddle back home ,where not sweating and the motor doing most off the work .
this is the map a done on google see it’s nearly one straight line. And give you idea how steep the hills are this 5 mile of me journey , so don’t know if the yose power 250w or 350 w would be enough or to weak with stock controller ??

But been have look on the internet and a have come across this motor never heard off it but
It’s a part of Bafang but there not much info
On the net about it ??
SUTTO 250W 36V Rear Hub Freewheel Electric Bike Hub Kits with DZ40 Display
In this case, Varstrom helps you select everything needed for the eBike conversion, you only need to choose a favorite battery from or out of Varstrom, then you can start your electric bicycle modification plan

but it’s 36v controller but since Bafang KT controller could not swap this for KT 36v / 48 controller so have 250w with 48v ???

A just think 15 little bit to slow 19/21 is very comfortable and gets you A to B in reasonable time 15 can peddle fast than that but obviously not for that many miles .
In which case you have a choice. Buy a 350w kit that you can set the speed limit to what you want, knowing it is illegal, or get an e-moped with road tax, insurance etc. You can set the speed and throttle with the Yose 350w kit.
I have 250w and 350w Yose kits and was very pleased with both of them. I think you are being too fixated with speed. The difference between 15 and 21 mph on arrival time over 10 miles is negligible. I updated the 250w with a KT controller to get a higher top speed, but in practice I've found 15.mph fast enough and set it accordingly, with the peace of mind that my bike conforms to the regs.

You should look for a 250w 48v kit. The problem is that you have to search very hard to find a kit with everything: 250w, 48v, 29", rear, cassette motor. Its easier to buy the parts separately if you want the best, otherwise you're pretty well limited to the Woosh kits, which are adequate for what you want.But been have look on the internet and a have come across this motor never heard off it but

The controller and display will both be Bafang brand SZBF denoted, one can't simply change the controller for a KT model as it will not be compatible.But been have look on the internet and a have come across this motor never heard off it but

If you want 250w & KT then one needs to buy a 250w hub and the controller kit seperately.

It’s getting them compatible that’s the thing
It’s like mind field all these different controllers rear hubs you don’t know if there just labeled 250 or there 500 relabelled , it’s lot harder than thought. Loads off 250 w 36v but not many 48v
a could think about mid drive route but that’s got problems with chain alignment and chain snapping 10 mile away from home ,
know wonder delivery drivers around the town just do basic 500w Bafang and 48 v battery as there loads them kits and gets you 24 mph what a do think is to fast for bike looks suspicious
but thanks all input guys appreciate it and have red every ones comments
am starting think that two a think it’s like 12 minutes slower getting home from work
Think might go yose power route with built in controller and buy couple spare 36v 13 amp battery and charge at work ready for finishing work by spare charger from them to keep at work
If go this route a know motor switch off after 15 mph could peddle to push past that or does the motor stop you bang on 15 mph ??
If you use a bike for work every day, you'll be observed by many drivers. It only takes one to grass you up because they get annoyed by you filtering to the front at a stoppage or because it took too many seconds to get the opportunity to overtake you. Many of them will be driving to work as well, so they'll see you every day and be able to predict your presence. That's the biggest risk, AFAICS. If you were riding at random times in random places, the only danger would be if a police officer observed you or stopped you during at a coordinated event of some sort.
Personally, I think the risk is too high now, and the gain you get from an illegal vehicle is not enough to make the risk worth it. The police are much better informed on what to look for than they were in the past. You can get all the power you need from a legal bike. It's only the speed you'd gain, which over an 8 mile ride makes about 6 minutes difference. It wouldn't be 12 minutes because a lot of the time the speeds would be the same, like on any incline and every time you have to slow down and start up again.
If you really want to do the journey quicker, get a 50cc scooter. It'll be quicker, cheaper and more comfortable. Also, you get a much longer range and can carry more stuff.
If you got a KT controller, you could set it to exactly to 27.5 km/hr with the GPS in your phone, which is technically the limit because EN 15194 allows a +10% tolerance.
I can't understand why you're stuck on Yose, when the Woosh 48v kits should be better for you.

I regularly do around 17.5mph on flat. I have a downhill that when there is a good tail wind I've managed 26mph.
My bike is geared with a larger front crank as the original one felt too slow. I also got rid of the knobbly tyres and put on Marathon pluses.
The electric power gets me up said hill on the way home and on the flat accelerates the bike to 15.5mph where I take over.
If I don't feel the urge to go that fast I don't and let the bike take the strain.
I also have a comedy folder with 20" that I've just converted. I struggled to pedal that up to 15.5mph in the lower assist settings. When I was setting it up I managed 17.5mph on the throttle and it felt flipping dangerous. About 12 to 14mph is a comfortable speed.
For compatibility one can't mix and max controller or LCD/displays.
Lishui and Bafang are hardest to match as often the two components have to be matched form the same supplier, vendors may use differing software then another.
With KT one can pretty much guarantee 100% compatibility , alll one has to chack is the connectors are the same for plug and play, OEM KT stuff may use custom software and settings so one has to be careful if trying to mathc up OEM KT with generic KT.
Many of us have used generic KT purchased from various sellers with out seeing any non compatibility issues.

The yose controller will just stop applying power to the motor beyond 15.5 mph, it wont hamper you beyond the mass burden pedalling any faster, so if you could pre conversion you can again post 
. And with motor assist to get you upto and at 15.5 mph you should have more energy to devote to top end spinning.
Ive crossed paths with plenty of folk who would take pleasure in spotting and reporting a 'suspicious' 20 mph ebike, and if you haven't im pleased for you.
yose-power employment of either julet connectors or the smt automotive style connectors is basically the generic industry standard that all ebike controllers employ.. the odd brand may add their own twist to monopolise spares resales? and bafang/higo connectors can muddy the waters if unaware, and while there are a couple of known gotcha's NONE apply to yose-kits afaik so rest easy on that score..
Topbikekit can even sell you a 48v kt controller that fits inside a hailong battery base, if you buy one? I for one would lurve to know if its a dual voltage capable 36v/48v device or just 48v as the site description is a bit ambiguous.
- the more compact space than within the 'silver box' format, could limit circuitry options??
Making an ebike travel at 20 mph isnt difficult, the question to ask yourself is however is it a wise thing to do?
And if traversing areas unpopulated perhaps it is but on the same roads day in day out?? -
Perhaps if your the most courteous and polite fast ebike on the road givng NO-ONE any cause to raise an eyebrow you will be ok??..
