say you are riding a 10 speed road bike and speed 5 is the comfortable one. with that gearing the next up is straight to gear 8 on that bike so it's a very big jump and at 80 gear inches I know i won't even be using that on FLAT ground and would only use it on a slight slope or more! it's a useless gear. The single speed Carryme might be a better option with the GI in the mid 50's.

Also i just went to the pacific cycles main website and the new carry me Dual speeds are $1015 USD!?!?! wow that's very hard to justify plunking down that much cash for that bike that doesn't look like it's main purpose is for long rides! But the bike is extremely well built and easy to drag around with those tiny trolley wheels. Plus no one will probably question you anywhere because they won't even know that this contraption is a bike.

But i gotta say their own upgradable 2 speed drive kits price is very reasonable instead of the crazy price a schlumpf costs!
