TK pro went together in about four hours. We watched the instruction video several times and it was very useful. No major problems. All necessary tools come with the trike. The packaging was basically superb. However, the box was taped both at the top and along the edges at the bottom, so to remove the cover, besides pulling out the white plastic anchors, it required lifting the box and slicing the packing tape from below. Took time. The assembly was basically easy. Note: unlike on the video, one needs to install the front fender before putting the front wheel in, otherwise the little metal lip that holds the fender up won't go in and you will have to take the wheel off again to put it in place. The rear fenders do need some fiddling to tighten them up in place but after it's done right there is no rattling at all. Access for tightening the anchors is not easy. The video says to remove the back rack for better access, but I didn't have to do this. One note, rather important actually, when removing screws such as for the front basket assembly, make sure to reinstall them in the same hole they came out from otherwise they have a tendency to lock. This could be due to how the threading is originally done; to avoid any issues, don't switch the screws around basically. Reinstall them in the same hole they came from. Battery was charged up out of the box, but the tires needed to be inflated to proper pressure. Riding an eTrike is very different than riding a bike. Be mentally…
