What is the max weight a standard bycycle would take? I would like to get back into cycling again, however over the last couple of years I have piled a few needless pounds on. I currently weight 178kg (392 lbs), would a standard bike frame withstand my weight? I'm hoping to loose substantial weight hopefully by cycling each day as I've never been much of a runner. But do I need to loose this weight before I start cycling. I had been looking at the Carrera Vengeance Mens Mountain Bike 2015 - 22".
178kg would put significant strain on most off the shelf bicycles. Most critical parts would be wheels, bottom bracket, crank set, and suspension if any.

I would suggest that you go to your local bike shop and have custom assembled bicycle for you with:


wheels 26" with at least 36 spokes, best quality double walled rims, best quality spokes and good wheel builder
robust steel frame with no suspension
wide tires
bottom bracket and crank set with external bearings like Hollowtech II, or better
