i try buy which electric Trike Conversion Kit and battery for KMX Typhoon

For that 20" wheel in a recumbent you need a quite powerful legal rear wheel motor Jatinder. The eZee kit had often been used for that purpose and it has a variety of batteries and mounting options:

I don't know of a low price high powered one for a 20" rear wheel Jatinder, but perhaps others will have a suggestion.

We need a bit more informationfrom you to be able to advise correctly.
How fast do you want to go?

How far do you want to go?
How much can you pay?
Are you good at DIY and do you know about electric stuff and can you solder?

Most of the 36v hub-motor kits will be much too slow in a 20" wheel - maybe 15mph max.

A 312rpm Bafang BPM will give about 20mph in a 20" wheel at 36v,so with a 48v battery, it'll just about reach 26mph - about £460 -£500 for both.

If you need cheaper, the 328rpm 36v Cute motor will do about 26mph at 44v. I think 48v would be too much for this motor, so you need lipos for the battery. You won't get as much torque as the BPM motor

The motor is for 13.5cm wide bike.
This motor is less powerful than a Bafang 250w motor, so should be legal in UK with the 15amp controller in the kit.
You should select the 328 rpm option, which will give approximately 20mph in a 20" wheel. You want 26mph, which is not legal. If you really want 26mph, then you must use 12s lipos for 44v (48v average). I don't think that this motor is strong enough for a 48v LiFePO4 battery unless you reduce the current to about 12 amps. The 36v controller in the kit can run OK with 12S lipos, but not a 48v battery, so, if you want a 48v battery for higher speed, then you need to find a 12 amp 48v controller, which will be expensive. You could get the Greenbikekit 9FET controller and cut one of the shunts, which would give 11amps instead of the normal 22amps. A programmable controller from Ed Lyen or Emissionsfree.com would be better.

No problem i buy for 20mph (328 rpm) - 36V250W~350W GBK-100R electric bike kit, rear driving e-bike conversion kit, let me which can work with 36V8.8Ah bottle battery/bottle shape battery for electric bicycle with charger can full speed 20mph?

21mph is the speed without load. 18mph would be about as fast as it'll go without pedalling on the flat. These motors are not high torque, so will slow down on the hills. You can get 20% more torque by soldering half of the shunt in the controller, but I think that the bottle battery can't give that much power.

21 mph is speed without load. The motor is small, so doesn't have a lot of torque. The rack battery in the kit would be able to give more mower than the bottle battery. In your first post, you wanted cheap, light-weight and legal, which is this kit

f you want 20mph without slowing down, you need this motor, with 312 rpm:

and this battery:

You have to buy a charger too. The weight of this kit is double the other one and it's not legal, but that's what you need to sustain 20mph.

Until now, I've never heard of anybody being prosecuted for an illegal bike. It's almost impossible to prove that a kit is illegal if it's restricted to 15mph. Any kit that takes you to 20mph is illegal. Many of the ready-made supposed legal bikes that you can buy will go up to 20mph. Just don't run anybody over and you should be OK. Also, that motor's so small that nobody will notice that your trike is electric.

i see read sometime what's mean - tricycle – 0,25kW?

0.25 kW is just another way of saying 250 Watts. That's the old UK law that you've read, 200 Watts for bicycles, 250 Watts for tricycles. The EU law that we are subject to now is 250 Watts for both bicycles and tricycles.
