https://www.amazon.com/dp/B01M7S0DQF?ref=ppx_pop_mob_ap_share could of sworn that I included the link to the knee pads in my post. Both helmets you are looking at do not have chin guards which is a non starter for me personally. I saw your scooter can reach up to 25mph same as my emove cruiser. When I ride to and from work every day I wear a full face motorcycle helmet/mountain bike helmet, a mesh coat with ce rated back, chest and elbow protection during the summer and have a riding coat for the colder months. I also wear the knee pads or riding pants and boots. For gloves I currently have a pair of leather gloves but I'm looking to upgrade. When you fall you want gloves with wrist splints that will stop them from hyper extending so you don't have to wear a medical splint for a whole month like me.
There is one piece I really went all out on, and I do not regret it.
Less expensive alternatives may protect as well or better. This one, although pretty pricy at $260, looked flexible and comfortable. I knew if I bought something that limited my mobility, eventually I would stop wearing it.
You may not need equipment like this, it depends on how and where you ride. I see this vest not just as a measure against falling, but also cars.
The larger point I'd like to make is that with any piece of gear, you won't regret spending the money on something that is comfortable. If your cheap knee pads dig into your shins, even a little or only while turning, you could tough it out and save a buck. Or, you could spend the extra money and never let that be a nuisance to your otherwise (very freakin) enjoyable experience.
That said, protection is priority. Medical bills can be WAY more expensive than even the most expensive gear (Full body airbag suit $1100), and you can't put a price on a lifelong injury.
Oh, and these knee/shin guards. Worth it at twice the price, guaranteed to make you feel like RoboCop.
Ride safe, ride far.
I'd honestly return that helmet and get a downhill/motor cross helmet at a minimum. It's not if you will crash but when and even if you are. Going slow doesn't stop a car from crashing into you. [I use these](Leatt Black Large/X-Large Knee &... https://www.amazon.com/dp/B01M7S0DQF?ref=ppx_pop_mob_ap_share) for knee pads. Super quick to take on and off. Some people will say it is overkill but I rather be over protected than under protected.
I'm 6'2", 235. These are what I use.
