Having decided that this company was the one to use to enable me to transform our folding bicycles we firstly sent pictures and details of the bikes to them. They confirmed that their kits would fit them perfectly as would the seat post adapters. The battery holder does not fit the handlebars nor does the saddle tube adapter, it’s is too small to fit the tube. We upgraded to the led display and control panel but this is also a disappointment for to change down a power setting one has to completely cycle up the settings before it returns to a lower one, this is quite a distraction whilst cycling. On the plus side the motor is quiet and powerful and the battery appears to hold its charge well although we have yet to travel far enough to determine how powerful it really is in normal conditions. I can provide photographs of the above points should the company wish to follow this up but having already sent them photographs of the bikes in the first place I’m not sure they will study them in the detail required now that they have sold two kits that that they confirmed would be suitable.
