Another question from this newbie. Started riding to work this week and absolutely loving it!!!! BUT couple issues regarding my bikes performance. I knew buying a cruiser that it certainly wasn't going to be overly fast but a bit surprised at its lack of speed up hills. For those that know canberra, along the tuggeranong parkway there are a couple of hills, now on this my nike struggles massively to hit 100. It screams along in 4th gear at 80, if i hit the hill in 5th it really struggles. Today on the way home i had it wound up and maxing out at 80 in 4th and then changed up to 5th where it slowly trickled to 100 but that seemed a lt of effort. Is this performance normal for this bike or is there something i need to look at? If its normal im thinking a larger 900 or so Kwaka cruiser might be required sooner than i though.
