Just installed this on my Mini 4.  Can any of you knowledgable people advise me of a controller and display to connect to this. 

Does anyone know where I can get a 1000 watt Bafang hub motor ready laced into a 20 inch fat rim please. ?

Any thoughts on this new bike. Old battery style so you can turn it off. No suspension. No display. Step through only. Better colour scheme. Better handle bars. Price. https://youtu.be/rlmC8iS3l_4

Keeps coming loose while riding . I am constantly re tightening the two bolts despite using Loctite. Anyone else had this problem and have a solution ?

With the extra speed of the upgraded mini. I find I am pedalling like crazy when 20 or more mph. Would changing the cassette or front chainring to a different size slow the pedal rate down? I would like to pedal more at higher speed in 7th gear. Has anyone tried this ? Any suggestions?   Tony

Has anyone used the upgrade controller from Big Game Bikes in the U.K.?   Tony.

Has anyone found a small triangular bag/pouch to fit in that small triangular area of frame on the mini folding ? Tony
