These kits can be purchased either from the yescomusa.com website or on ebay. Search for '48v 1000w'. Price is $289 from yescomusa. As low as 275.90 shipped if you use ebay. The actual motor is manufactured by Golden Motor. Their motors are used in many kits. Like most kits it includes the the motor in a 26" wheel, which seems to be of good quality. It comes with a decent 26x1.75 tire and tube installed, which I promptly replaced with a 26x2.125 65psi tire and tube. It also comes with a 5spd freewheel with 14 cog high gear. On my first kit I replaced this with the original 7 spd freewheel off the bike, but realizing I rarely use anything but the highest gear, I didn't bother doing it this time. Makes install much easier and you wont miss the lower gears. It also comes with a rear rack that is solid as a rock. I installed it on my first kit, but didn't this time around as I wasn't going to use sla batteries. Installed the rack easily held my 125lb wife bouncing up and down on it so it is very strong. The bag and long bungee strap is capable of securing about the biggest sla batteries you'd want to use, although sla batteries suck for many reasons. I use lipo now. the rest of the kit is pretty much standard stuff, a pair ebakes to replace your regular hand brakes. A thumb throttle, which I prefer over the twist throttles and a pair of new grips if you need them. A 48V controller and a 48V 2.5A battery charger. And lastly an installation manual with lots of pictures. Basically everything you need except for the bike, tie wraps and a battery pack. Where you mount the controller and battery pack will be your main decisions and this will depend on the bike style you have. I've moved mine around a couple of times. So much for that. Now to the performance. I'm a big guy at 270lbs, so you will likely get better numbers than me.
Bike: Kent Sierra Madre 26" 21 spd (now 15) with full suspension.
Battery pack: 14s lipo (51.8V nominal)
Max speed on level ground 35.0 mph
Undocumented controller features.
The controller is an EB215-A-5 with 15 80NF70 mosfets. All caps in the controller are 63V. The controller supports many features that are not enabled by default. These include cruise control, regenerative braking, anti-theft wheel locking, forward/reverse operation, and 3 speed switching. I can verify that cruise and regen braking work great. I can only assume the others will work too, but I didn't try them.
To sum things up, I think this is one of the best deals available. I don't think you'll find another kit that will give you these features and performance for the price.
