luis_teixeira Fill these at 3.2 - 3.4 bar (46 - 50 psi) and you should be fine.

luis_teixeira Hi, this car stereo should fit on any double height slot that follows the DIN standard. Its dimensions are 178mm * 102mm*43mm, which is within the DIN dimensions x 2 (180 x 50 mm). And because its depth is only 43 mm, it leaves a lot of room behind for ventilation or cabling. For that car in particular you will probably need to replace the dashboard frame around the slot for aesthetic reasons, as it appears to have its own infotainment system featuring a DIN (x2) but with a custom layout of buttons in the front. If your infotainment system provides car functions, you may also want to take that into consideration, as it might be difficult to preserve these functions with the new car stereo.

luis_teixeira It should be firm enough so that there is some resistance to folding. It will get loose again after some rides, so it needs to be tightened periodically. In my case I have added an extra self-locking nut and applied threadlock to the threads around the 2 nuts. If you have to fold the scooter frequently you will notice the noises appear sooner, as there will be some wear to the plastic joint that is sandwiched between the lever and the folding axis. The thickness of the plastic will decrease, causing more slack between the parts.

luis_teixeira It weights about 50 Kg, just the scooter itself. Battery pack contributes with about 10 Kg of the total weight. Battery deck and most other structural parts are made of relatively thick aluminium parts which are a significant contribution to the overall weight.

luis_teixeira I normally fill my road tires to about 3.2 bar (slightly below 50 psi). I also check the pressure every 2 weeks or so. I think in any case (road or off-road) you should not let the pressure drop too much, because as these are tubeless tires, without enough pressure it won't form a sufficiently strong seal between the rim and the tire, causing air to escape.

luis_teixeira Apparentlythe battery is made up of Lishen LS LR2170SA cells. It is provided by Dongguan Bangsheng Energy Technology Co., Ltd. This seems to be a custom pack not listed in their product catalogue.
