Overall the kit is brilliant. Only a few things which could be bettered in my opinion. 1) The difference between the battery indicator on the battery itself and the battery indicator on the LED Display are always showing different levels. From what I can gauge, the display battery is adaptive and shows the "real" remaining battery dependent on what assist level you use. 2) The LED Display. The display itself is useful and easy to use, however the display did not fit my handlebars (standard sized drop bars). The plastic is also very thin causing mine to snap (currently have my display taped to the bars to use the kit properly) Would also be great if in future kits, you could link the display to Garmin products to get the true Ebike experience.
