Heavy loads in rear - Front wheel lifts off ground

Does anyone else have this problem when the rear of the bike is loaded up?

Occurs when i'm going up steep hills

What do you do to cure this? Just simply load the front with more of the weight?

Seems to me your options are:

more weight on front wheel OR
Xtracycle (longer wheelbase) OR
trailer (and good balancing of the load on trailer).

You could also try to lower the centre of gravity of your load on rear rack, but you might not be able to lower it enough to make any real difference.

Or move the weight forward, but still on the rear rack. You are essentially looking at a lever, where the fulcrum is the axle of the rear wheel (when on flat ground). If you can get the weight forward of the rear axle, this problem will likely go away.

Or just scoot forward and weight your handlebars. This is the solution when mt. biking up steep hills with no load. If your load is 30 lbs and you are 150 lbs, you could probably solve the problem by leaning forward a few inches.

Climbing with a loaded rear (you can take this any way you want!) you will usually find me standing on the pedals with my nose just about lined up with the front edge of the front tire, pedaling a steady, maintainable cadence.

It doesn't take much for this to happen with me either. I tend to keep the rear derailer on 5 and I only change, the front derailer, so I start in a mildy low gear. When I am climbing I usually bring it down to 4 on the rear and when I start off my back wheel tends to go up. For anything more than 30 pounds though, I use my trailer.
