The bumpiness is always there since the first day. Is it that there is no problem at all, only that I compare with my previous ride ?
The DIY to press down and release the boot has no problem. It doesn't bounce up and down.
For those who stays near the NTU area, maybe you can make a right turn at the T junction of jurong west st 92 into pioneer road north, just opp the city harvest church, to see if you experience the same as me.
