Just got a pair of Clarke hydraulic brakes on impulse. Local shop selling up and seamt a good price. Two questions . Will I need to get cut off brake levers. Would I be wise to replace the rotors or will the ones from the Tektro mechanical discs be ok. Thanks for any advice

The old discs will be fine.
You could use some brake sensors on the new levers, I've opted not to bother on the bike I've converted (my GTech doesn't have any brake cut out and I've not had any issues yet). It's going to depend on how quick your motor stops after you stop peddling, mine is pretty instantaneous, so I thought I'd take the chance and see how it goes.
I am a bit of a newbie to the electric bit of bikes though, so hopefully someone with more experience will be able to confirm if I'm talking rubbish.

You need brake sensors if your motor runs on after you stop pedalling. The response on modern bikes is much quicker now, so they're often not required.
Be aware that if you have a throttle and it breaks when you fall off, it'll make your bike run with half maximum speed. If you try and stop it with the brake, the controller will blow. If that worries you, you can put a simple switch on one of the old brake wires, which will cut the motor instantly. You can of course switch the battery or LCD off, but people often panic rather than use logic in those situations.

Just to follow on from my earlier post. I've now properly ridden my converted bike and had no issues without brake sensors.

Thanks guys. Got them fitted without too many problems. The pipe for the front brake is a little tight. Is it a big job to fit a new one. I assume that if I had brake levers with sensors I would need to do that. I have kept the sensor cables in situ. Other option is to switch front brake to left??.
I'm surprised the hose is short.
Most pre-bled brakes come with a hose which, if anything, is a bit too long.
Of course, it depends how far the lever is from the calliper, so if you have a raised stem for the handlebars that will make a difference.
Fitting a longer hose is possible, but it will be a bit of a faff because the brakes will require bleeding.
Plenty about that online, but it involves a syringe, containers, and messing around with fluid.
By the time you've bought a new length of hose, a bleed kit and associated olive connectors, the new brakes may not be quite such a bargain.
Shimano hydraulics are excellent.
No need to buy expensive ones, the basic models do just as good a job.
They come pre-bled, complete, including levers.
As I mentioned earlier, the front one may have a hose that might be a bit long.
It should be possible to route the hose in such a way that it doesn't need shortening.
Lengths are given in this link, looks like a metre for the front.

learn to do it yourself. It's not difficult and saves you some cash too.
You can re-use the old olives, may need new inserts.
