When I pedalup, I need to jump like 15cm higher than I normally would because whilst pulling up the bike, my body starts dropping down thus not allowing me to pull the bike up as high as I jumped in the first place. This is only to do with pedalups - taphops are better. No such problems when sidehopping or pedalkicking upwards. Only have this problem with obstacles over 80cm, which is actually quite small taking into account how high I get my body when jumping upwards. Is this to do with timing or incorrect body movement? Having this problem for about 4 years now, it's the only reason why I cant get onto obstacles from a rolling start. edited this, hope it's more understandable
