Assembly

VERIFIED PURCHASE
I purchased the M3i Studio Plus. Packaging excellent, I like the double box to product the bike. Parts packed beautifully. I look at the tool list, no problem I have all the tools, although a lot of buyers may not have required tools. Keiser let me make a suggestion, either go with a 15 mm or 16 mm not both, as you can get the same torque values with either one The average user is not going to have 15 or 16 mm, or even a torque wrench, maybe self tightening fasteners with loctite? Instructions are very clear. I would suggest people that are not conversant with hand tools to mask of certain spots in the event a tool slips. Maybe use one type of common head fastener, as I can see, and I’m sure it’s happened, someone trying to force an Allen key to a Hex head. Build quality...
