You have to find your own rim and spokes, which cost about £30 if you build the wheel yourself, otherwise about £30 more to build it.

You can get similar with the Yose Power cassette motor kit, but then you're stuck with 36v unless you sling the controller and buy the 48v one above, so you bought the ready-made cassette motor wheel for £200.

Thankyou , yea , I don’t want to get into building wheels etc , My budget might stretch a bit to avoid that, also I should have added I am I Scotland so I need something that will tackle everyday hills as well !

 

[vfr400]

The most important thing is that you get the right kit for your needs. It doesn't make sense to save £100 to have something that's less than satisfactory.

To give you best advice, we need to know how heavy you are, exactly what sort of hills and how hard you expect to pedal.

Ok , I’m 63 yo , 5’7 and 12 st , my usual terrain is in and around Edinburgh with its various inclines .
I dont want to be puffing and red in the face after 100m up a hill . But I’d like to be able to get around with relative ease with a bit of ooomf . Thanks

 

[vfr400]

A hub motor is generally better for the road, but a mid motor can offer advantages for very steep hills and or heavy riders. You should be OK with hub motor at 48v. In fact at only 12 st and the hills around Edinburgh not too bad, I think you'd be OK with a 36v setup. You'd be surprised at how much difference even a low powered ebike makes over a non-electric bike.

To summarise, the Yose Power kit would have enough power, but you won't be going much faster than 20 mph. You have to go to 48v to get a comfy 22mph, which is a nice speed. Woosh Bikes also do a cassette motor kit, which you can derestrict to about 20 mph.

Finally, a BBS02 or BBSHD mid drive can give the performance you want, with the disadvantage that you don't get such a comfortable ride, and you get more wear on your chain and gears. There's not a massive difference. A lot of people use them and are happy. I just prefer the ease of use and reliability of a hub motor.

 

[RON FAIRWEATHER]

That is very helpful , thankyou . I wasnt really considering a rear hub ,can you recommend a supplier for the kit ? Should I go for a 48v rear wheel with a 48v . 17A battery ,or the mid drive , by the way what is BBS02 and BBSHD? Thanks Ron

if this is your first conversion, get a BBS01 kit. It's simple to fit and totally road legal.
If you are on a budget, take a look at the XF08C kit.

Yose cst I have will do 24mph @36v, though you will need to be fit to maintain it.
Controller is not the std one but a 25a 9fet sinewave KT.

 

[RON FAIRWEATHER]

I am happy to pay a little more to get more oomph and distance , I’d like to do some minor touring with it .Do all the batteries have compatible hook up connections?

 

[Woosh]

.Do all the batteries have compatible hook up connections?

No.
Each battery case comes with its fixed side connector.
You find most of the popular cases from this manufacturer:

In principle, yes. You can use any 36V battery with any 36v controller.

Some batteries have a compartment into which an optional motor controller can be stored. You can buy the battery with or without the optional controller. If you buy a kit that includes the optional controller, the installation can be neater, but it limits which batteries you can use in the future.

 

[Woosh]

In principle, yes.

in principle no.
Try to connect a rack battery to a downtube controller for example.
Some kits are a mess. Wires everywhere, poor protection against water ingress, vibrations, cable snags etc.
If it's your first conversion, try to keep things nice and clean.

 

[RON FAIRWEATHER]

Also should have said I would prefer not to have a throttle , it hurts my wrists , but are they essential to achieve higher speed with certain kits ?

 

[vfr400]

When you have a throttle, you don't have to use it, but there are always times when you will find one extremely helpful or even necessary.

 

[RON FAIRWEATHER]

Thanks folks , so is there a kit with a battery , off the shelf , I can get my local bike man to fit ? Is the Electron stuff good value? Cheers

 

[RON FAIRWEATHER]

Ok , It looks the best option is the rear 48v hub wheel and 48v battery , can anyone please advice the best supplier with after sales etc and name of kit , also, can you get a rear hub kit that has pedal assist option ?
I’m a bit worried of buying blind on ebay direct from China etc . Thankyou

For the UK then use Woosh as they meet all your requirements & 250w , SWX 02 kit for freewheels
48v rear Yose kit form Germany for cassettes, when they are in stock. Marked 350w.

A throttle is nice, even if you don't use it, because you can power on your bike, lift the wheel, flick the throttle and you know right away if the bike is working.

Part of my pre-ride check every day, Don't want to coast down the little hill leaving my place and find there's no power when I start pedaling.

 

[RON FAIRWEATHER]

Thankyou , Ill go with a throttle then , is the thumb throttle as easy to use as the twist , if J only hope to achieve a top speed of 22mph will a 36v kit do the trick ?
