36V 48V 1500W 20" 24" 26" 27.5" 28" 29er 700C Rear Wheel ebike Electric Bicycle Conversion Kits with 750C Colour Display

I converted my Cannondale to an E bike, I bought a separate battery a large one with a rear rack that came with the battery 48 V. It took about two hours to mount the rack and the battery onto the bicycle. When the Hollyn motor box came it was very well wrapped and protected. It came with some paperwork written in Chinese but there were no directions. The good thing was it came with all the parts and pieces needed, and with a little bit of mechanical ability and making sure I use YouTube, I was able to figure it out. The first thing I did was about the rear wheel and I use the inner spacers between the sprocket and the frame of the bicycle and the hub in the frame. This is super i portant. I also connected the display center, front and rear brake handle bar controllers, and bought a crank arm puller on Amazon and out of the pedal assist sensor. Next I went to the auto parts store and bought a cloth wiring harness holder called easy cool and nicely put all of the wires going from the front of the bicycle to the rear control center. Then the plugs are very specific to the receiver plug and I use the easy cool to make those wire connections all look nice and neat. There were two dummy plugs on the control center that had to be pulled out for me to use the plugs in the wiring harness, you’ll understand. After that it was a matter of wiring up the face connectors which is a yellow and green and a blue wire that will go to the battery of a yellow green blue and bolted with a little yellow connector box. I had to solder the negative than positive battery connectors to quick connects so I could take advantage of the universal plugs that came with the battery. I also ordered a axle control arm on Amazon which is basically like an old or a pedal brake to keep the axle from slipping on the frame mount. Make sure the battery is completely charged and connected well. I turn the power to the battery on, turn the key on, turn the display on, and I selected the power mode I wanted for the test ride. It works fantastic. I really would’ve given us three stars except the equipment and the packaging was so well doneThey really should invest in some instructions or copy and paste this with pictures for people to do the work

Kit came with kt controller and a ukc1 display which are not compatible with each other. Luckily I just used the controller and screen from one I already have. Contacted seller (at the time didn't know ukc1 screen not work for kt) stated to seller screen wouldn't work and that the display from other kt controller works. Got told to send pic of wiring don't remember if I did or not. By this time I had run out of patience with controller and screen that came with and just used my existing one. The motor is good tho.

i built a diy ebike with this set up ,and could not be happier.
