I bought a piece of 1.5 inch stiff foam to try to fix a sag in a bed. It didn't work but having that thick piece of solid foam around has been a life saver.
Need something flat to put a laptop on? Throw it on the foam. Going to be doing something that requires you to be on your knees for a while? Get the foam!
It went from stupid purchase to something I'd gladly replace if it broke.
can we get some more deets on what you use it for in terms of terrain/altitude/distance/weather?
Seriously considering an ebike to replace a 20 minute car commute (12 miles). There are some 750w used bikes on my local craigslist for ~1-2k USD, but there's also a super cool dual-motor bike with rear suspension for $3k. Any advice?
