Another Tern's latch problem. If it happens in the US, the whole bike's shipment would be recall back to Taiwan. In Malaysia, anything goes......
Don't buy this bike until they solve all this problems.

Hi everybody,
Obviously, when there’s an accident, it’s of concern and we need to understand it. We’ve already reached out to Samo for more information.
However I can say the following:
• The Physis handlepost is manufactured by one of the best forging companies in the bicycle industry and it is CNC machined to a tolerance of 50 microns – it is very precise.
• The Physis handlepost has been independently tested and certified to exceed the European EN standards.
• Based on our overwhelming confidence in the strength and durability of the Physis, we have increased maximum rider weight limits to 110 kg (242 lbs.) on 20” bikes and 115 kg (253 lbs) on 24” bikes.
• Thor is right – the safety pin can be broken if enough force is used to try and force the lever open. We designed the pin to break at a certain amount of force – an initial beta design used a stainless steel pin but we found that it would permanently damage the joint if it were forced open and we anticipated that customers would be much more unhappy with a permanently damaged joint. The safety pin is designed as a secondary safety system.
• The clamping mechanism is based on an Over Center locking system. This means that when it is adjusted correctly, it will not open, safety lock or no safety lock. Millions of folding bicycles have shipped using this type of Over Center locking system.

so from Josh's explanation, even without the safety, the latch would not have opened by itself.
I went to have a look at the latch and compared it with the one from Dahon speed P8.
The tern design, it will just made a very shallow ' click ' and considered ' locked '.
With very minimal force, u flip the latch , and then use some force to push the post and it will open.
Compare to the old Dahon design, the one on the speed P8, feels like a ' quick release ' type.
If u have quick release wheels or seat post, u will know that the more u press, the harder it clamps and the more secure it is.
