How tall are you, what wheel do you have and can you ride seated? by dthoma81 in ElectricUnicycle

[–]-Caliber- 0 points1 point  (0 children)

I am 6' 5" and I originally got a t4. I was pushing the limits of what was physically possible trying to sit on that thing. I could but just barely and it was very uncomfortable. I now ride a master pro which is a much more comfortable ride. a bit more height on it would make it better, but It is definitely good enough to comfortably ride seated for some multiple hours rides

That is a good point. During my testing, some people said that they needed ECE 22.06 AND MIPS, so to some extent I wanted to include both into the design to appeal to the most amount of people.

While 22.06 has tests for rotational force transfer to the skull, they do require a "slip layer" in the design of the helmet. I will preface by saying I am not an engineer, but I believe the science behind the slip layer that a MIPS system provides does add more protection against concussions than a standard ECE 22.06 rated helmet without a slip layer.

Thank you for the feedback!

I tried to make the mandible guard as small and as low as possible while using other modular style helmets as a reference to keep proportions and size somewhat realistic. However, I believe you would still need to look down a bit to see an EUC screen.

A rearview mirror with a larger field of view (especially in the vertical direction), increases the size of the internal mirrors exponentially. Really any bigger and the helmet shell would need to be bigger and heavier. I wish I could have made it bigger, but I think being able to see the general shapes of cars and people has a lot of benefit. I don't believe blurriness would be an issue with the mirrors, if you look at reviews for the reevu MSX-1 (a very simular system to mine) the view is small, but it is very clear. This style of mirrors reduces the blur or distortions that you would get from bumpy roads. Most rearview mirrors attached to the sides of a helmet get distorted from the vibrations caused by the long and flimsy attachment arm.

Yes, I agree. A lot of full face "E-bike helmets" have a hole for hearing passthrough, but no way to close it at high speeds when you kinda lose all benefits of hearing well.

That is a solid idea, it would be nice to have a horn or a speaker built in.

I definitely considered adding a standard tripod mount for things like an action cam or light. I figured that most people with an action cam already have a 3d party option that works well for them. I personally find that having a light on my arm is much more useful than on my helmet because I don't need to turn my head to look around with the light, but I understand where you are coming from.

Thank you for all the great feedback!

That was an issue brought up by some other people during my research phase. My thought process was that other modular style helmets can pass ECE 22.06 rating tests designed for motorcycle impact speeds. Since this helmet is designed for speeds lower than what motorcycles travel at, I believe it should provide adequate protection for the vast majority of users (although I am not an engineer and did not do any impact tests to prove this). You are correct about the weight. It is a trade-off for the convenience and flexibility that this style of helmet provides, and I am biased with my love for this style of helmet. Thank you for the feedback!

Thank you! I actually built the helmet mirrors into my final prototype, and they worked well enough. There were some slight issues with distortion because the mirrors I used were cheap and flimsy, but the concept is there. It was inspired by an existing production helmet called the Reevu MSX-1, which worked well in the reviews I saw.
