For anyone trying to make a throttle work with their swytch kit I thought I'd share this info, I bought a third party bafang thumb throttle and did the wire "hack" where you swap the wires, I did as it said but didn't work , so it was sat there for months and today I thought hmmm maybe try a diff wire connection , so I went white to white, red to black and black to red as shown in pic , and guess what, it only worked !!! :-D is a Bafang BBS01 BBS02 BBSHD £8.99, Just thought would share for any other swytch kit users out there looking for a throttle, just tested , works well on flats , slight slope, crawls up hill, as expected, but get's there, gets to max speed on flat fairly quickly, I may upgrade to a higher amp output controller with an lcd one day to get that extra power on a hill, but not sure how much to push the "250" watt motor , or which controller set up be best , so will prob leave as is , ya gotta put a bit of leg work in or is just a motorbike lol
