Thanks Everyone!

When I meant "attack the hills". It really means just making it up to the top of the hills. He is at the lowest gear already. And yes, since he doesn't ride everyday, it is hard for him to get into the level that can ride a standard crankset. He is physically very active since he's a courier by trade. But it's different muscles used.

I'll let him know what you guys wrote. Thank you. And yes, we've been looking into spending about $400 to get it set up. Crankset for some reason is super cheap in Britain so we probably will buy it online and get one of the LBS to install it.

He doesn't want to deal with the LBS that sold him the bike. They try to rip us off by changing his carbon seat post for a cheapo $20 one! We didn't know any better until one of our friends mentioned it. They even fitted him to ride for triathlon. Really weird. Had all these problem until he went to one of the places he delivers to. Talked to them about it and they set him up with a more relax position. It's a long story but this bike is not the best experience for him. Wished we knew about this forum earlier before he bought this bike.
