DIY 1 set of 26″ 36V 750W front hub motor<\/a> electric bike kit from Internet shop,waited for a couple days,at last received it.
\nChecked packing box,it\u2019s okay.Disconnected package,there were all goods inside box: <\/p>\n

1.1 set of 26″ 36V 750W front hub motor wheel without tyre
\n2.1 set of 36V 750W bldc motor controller with LCD
\n3.1 set of twist throttle with battery gauge
\n4.1 set of brake lever with low voltage to brake
\n5.1 set of three-button switches(control horn,led lights,cruise..)
\n6.1 set of 36V 16Ah LiMn2O4 electric bike battery with 110~230AC charger
\n7.some zip ties(fix wires)
\n8.1 set of instruction manual and wiring diagram<\/p>\n

Was told to prepare below tools to install electric bike kit<\/a>:
\n1.open-end wrench(loose\/tight screw nuts)
\n2.philips screwdriver(fix LCD)<\/p>\n

By now,install electric bike kit seems very easy.But for a newer,first time to install electric bike motor<\/a> (hub motor) wheel and need to connect various unknown wires that is still a little difficult.
\nLeafmotor will share some install experience with every DIY bike kit rider.Some issues you will meet:
\n1.You are going to install hub motor wheel,you should find out the motor\u2019s direction of rotation first.Please read install instruction manual;
\n2.Install tyre according as flower pattern of tyre;
\n3.Fix 26\u201d front hub motor wheel on front fork.If your front fork is 100mm,no problem.After installed,sometime you will find the wheel isn\u2019t in the middle of fork,now you should use some washers to adjust.If still can\u2019t solve it,the problem come from spoke rim should re-fit this rim;
\n4.Fix bldc motor controller,LCD,electric bike battery and install throttle,brake lever,three-button switches.This step is easy;
\n5.Make the electric bike motor wheel in the air, power on li battery and test bike kit system.If it works normal.Please use zip ties to fix wires.If not,re-check wire connecting according as wiring diagram. <\/p>\n

This fifth step is the most important.When you power on battery,you may meet below issues:
\n1.The electric bike kit system can\u2019t work.When you turn throttle,nothing is happened.Now you should check battery power connector and three-pin throttle connector;
\n2.The electric bike kit system works as the fastest speed suddenly.The problem is the black ground wire from throttle isn\u2019t connected well;
\n3.The hub motor shake,please check motor phase wires;
\n4.All leds light,but electric bike kit still can\u2019t work.Check motor wires;
\n5.The electric bike kit works,but just wok less than 3 seconds,all lights on throttle are off.Loose throttle,be on and the bike kit system still works less than 3 seconds.This is battery issue,use volt-meter to measure it.Full charged 36V limno4 battery is 42V and dis-charged it is 34V.The volt of your new battery can\u2019t less than 34V.If it\u2019s under 34V,please return it to your supplier.
\n6.LCD doesn\u2019t display speed.Solve: the sensor should be closed to the detector.<\/p>\n
