Only 15 minutes spent and I'm surprised to realised that, even without significant improvement on my bike balancing, I still broke a lot of sweat under a cool rainy weather today in Annandale. It felt like quite a work out even though I haven't managed to successfully ride it yet.
I'm still having trouble maintaining a straight line - I kept steering to one side without meaning to, and then lose my balance. The car park under my apartment has a light slope that I practiced to slide down and just keeping a straight line, and I did pretty good with that, but as soon as I raise a foot to the pedal, my entire body just weight to one side.
I also braved the tiny lane that the car park leads out to. May be it was because the lane was curved up - I kept steering to one side there even when I was just sliding down (which I was pretty good at when I did it on the flat ground in the car park). I managed to pedal with both feet for 10 cm here and there before I crumble (not literally - I built an instinct to brake and land on my foot), but not often enough.
Will try again tomorrow morning, might even push to the nearby park and try it there with the fresh morning air instead of the stiffy car park.
