Suggestion: use a cable tie instead of the Strida clip to hold the bottom tube when folded.
I’ve not found the clip to be all that secure; the bottom tube tends to release itself at the most awkward possible moment, and the clip is always trying to escape when riding.
Instead, try putting a cable tie around the back tube just above the saddle mount in a big loop. The circumference on mine is about 12". You want to leave enough slack for it to easily slip over the top of the bottom tube in the folded position to secure it. When the front tube is folded up, it will press against the tie and make it snug. When the front tube is freed from the magnet to unfold the bike, it becomes easy to slip the loop over the top of the bottom tube so it can fold down.
The cable tie can’t fall off the bike, and the bottom tube will stay folded until you slip the loop up to release it.
