Chinese conversion kits.

How/where will use use the kit ?
On hilly terrain it will be pretty useless, they are usually wound for fast riding so expect 390 - 490 rpm, most batteries with these kits are woefully inadequate.
25/30a controllers which often these kits have really need a battery with pucker 15/20a rated cells in them as the drives are designed for high rolling speed and current draw to get the best out if them. At slower speeds below 20mph look for a geared hub for more efficiency.
The drives are D/D (direct drive) gearless drive and tend to be reliable, they are heavy 5.5- 6kg or so.

Hi, thanks for your reply.
I would be using it for leisure & mainly on roads or old railway tracks in my area. Iwas thinking of using eclipse battery http://eclipsebikes.com/product_info.php?products_id=147
Do you think would be suitable.? thanks.

The 29E to be honest isn't to bad a cell not the best but by no means not the worst to use on an ebike.
For your needs with a D/D hub you need to be looking at the 30Q at least shame it's out of stock though, also shame they don't do it in 13s 5p config.
D/D hub kits need a high spec battery which costs a few more quid, the best place to go to is BGA/Insat with 30Q or HG2 cells.

I would say that either it's the wrong kit for your bike or you have the wrong bike for the kit. For your bike, a lighter kit would be better, probably with a cassette motor. For the kit, a cheapo steel framed bike with freewheel gears (7 speed or fewer) would be better. If you want to go 30mph, you need big tyres, hydraulic disc brakes and, ideally, full suspension too.
Don't consider one of those kits if you want to run it at legal speeds. It'll be very inefficient and there are much better kits.

I'd encourage you to look at geared hubs for "normal" to fast road use
Got mine from these folks, pretty impressed, though I do regret buying a 10Ah battery as its range is only just enough:

I have the 1000W 48V setup you are describing and whilst it has plenty of power (I do all off road) as the other posters say it needs a good battery, so the whole setup is heavy. Even up the hills I rarely use above setting three on the controller (which shows 350 to 400w). So as advised in a previous post i am going to change for a 500w geared hub which is now on order.
Hi, I've had a look at that kit, looks quite impressive.
I see it's only a 26 inch wheel, my bike is a dawes hybrid with 700c wheels, so that might be the main problem with that kit.
Do you know of a similar kit with 700 wheels?
Thanks. scor24
Ok, I was looking at the kit https://www.ebay.co.uk/itm/36V350W-...746085&hash=item33bf69fcc6:g:C3IAAOSwdTJaXvku DynatechFan used. which only has 26 inch wheel whereby I really need 700c wheel, any advice.
Thanks, scor24
You could re-lace the motor into your 700c rear rim, just need a new set of spokes, which are fairly cheap.. I don't think there are many kits that are under £200 delivered without looking at shipping from China which works out expensive unless you buy a bare motor. You still then have the problem of fitting it into a rim.

That supplier sells 700c kits, though none listed at the moment. Send him a message to see when he'll be relisting. Don't forget that you need the cassette motor for 8 speeds or more.
Be patient the two sellers will probably have more kits to sell as they were very popular here and esp in Germany.

you can use a cable sensor:

They only work one way round, so you have to check which end of the cable to put it. Also, the connector sequence might not be correct for your controller, so peal back the heatshrink to check the colours and swap the wires around if necessary.
Loads more different brake sensors you can use with lots of different connectors for different controllers to save messing about:

If your kit has a fast response controller, you probably don't need them.
