well lets just say, i was born with bad knee's i myself can't run for more than 15-20 seconds without my knees feeling like they are about to snap.
i think back in 02-03 i bought me a mongoose MTB it was bright orange.. i loved that bike!
sadly it only lasted about a year due to excessive use and hard use at that..
i road trails, city streets levee's and even did some bmx dirt courses.
i ended up snapping the forks in half due to all the wheelies i did i guess lol.
boy did that crash hurt
but never the less it was a very comfy ride on all surfaces and conditions.
always kept it in 3rd gear seemed like the easiest softest pedaling gear.
very similar to this one:
