@@nokflyby No, not with a push rod like this. But since I made that video, many alternatives flooded the market. Look for springs which will be mounted in the hinge.

Hey Neil! I assume it's physics which struck ;-) There are some parameters to look at: First of all, is your string _really_ 100nm strong? Markings are, well, just markings - and some manufacturers are just a bit "optimistic", especially those from China. Then there is the law of the lever: How long is the spring (compressed) and how close is it's lower-end mounted to the saddle? It might be that the lower-end is mounted too high, so the spring has no angle to push up but pushing to the back of your scooter instead (giving a nudge changes this and it opens). So mounting the lower-end of the spring a bit lower should give it a better leverage pushing upwards. The downside will be a smaller opening-angle. Alternatively a stronger spring might work but certainly will require more force to close the thing.

@@my_niu thanks for reply. Yes, I was thinking it could be a leverage thing - but I don't want to drill lots of holes in my scooter to find out haha.... The strut says it is 80nm. - I'm thinking maybe I try a 120nm first, and if that doesn't help then perhaps look at leverage.

I got it working. 120nm took care of it. Not a problem to close and opens first time every time :-) Thanks for the video.
