Don’t use the supplied tools
I read the reviews before buying and noticed that around half were saying assembly was easy and the rest saying it was hard. I think the issue is the tools provided aren’t up to the task. It took me over ten minutes to do one bolt with the supplied Allen key and spanner. It decimated my hands and I couldn’t even get it fully tight. Then I got out my ratchet set. The next bolt took 30 seconds and that included fully tightening the first bolt. Don’t even bother trying to use the supplied tools. You need a ratchet set for nuts and Allen key screws.
