Assembly instructions are very clear and the bike went together easily. The bike feels solid though after using it daily for a couple of months the torsion brake creeks a lot. This may or may not be leading to a problem but it will make it harder to sell secondhand if ever I want to upgrade The computer operating instructions weren’t very informative though I worked it out after a few days. Saddle is hard and uncomfortable. I would have liked a chest strap to measure my pulse as the hand grips aren’t very effective. There’s nothing at all in the manual or online about this. customer services offered a little help but not enough for me to buy with confidence
