Imagine explaining it to the doctor, “How did he fracture his skull?” “Oh, he was riding a homemade electric scooter.” “Right….”

Notable efforts, and rather comprehensive. Makes you seem honest, which is tricky to come by today.

Hey, Great work, besides all the helmet talk i just wanna know… How to get my hands on a good frame, i saw earlier u mentioned a brushless outrunner quicker, but where else will i get the rest of the necesary stuff to make it, i was thinking of soldering two frames and having those bad boys on a plastic frame body go kart, something for my boy to enjoy… it seems a better idea than gas or electric just need a good cooling system maybe… any suggestions? Could i fit a bigger wheel than the small rubber ones? Large enuf to fit a good braking system.

AWESOME! Great work on the scooter Mike and Co.
Drop in for a drag at Flinders Uni next time you’re down-under. We’ll have a 3kW version ready to race you soon!

dood iv always wanted to do somthing like that to a set of roller blades lol would love to see the blue prints of it so i could try my own home brew version.
ps to all toughs that think that helmets are a must iv been a bike/motorbike rider my whole life falling a 25kph is no biggie. iv never landed on my head. hell if my face is aiming at the ground there called hands people it’s better to have a scar there rather than on the face. hell i know even motorbike helmets dont do much unless you scrape the ground and thats only grazes the think you need if your going to be anal where a neck brace like a gp bike rider when you fall your more likely to snap your neck on impact but other than that don’t worry so much about safty
ps if a car hits you or you get fliped at high speed you can kiss your ass good bye even if you are wearing ahelmet

Nice Hack!

I am curious about thermal issues. Duty cycle effect is often an underestimation multiplying damages.

With the rule of “down V= up A” as one further end-of-run parameter impacting thermal load. Brushless design sadly does not provide a nullification of electrical constants and curves

1500W is 2HP, but you’re measuring different things. A 2HP engine puts out 2HP. a 1500W motor *takes* 1500W, and puts out some lesser amount of energy in the form of acceleration. That motor might only be 50% efficient under typical load, so it’s only putting out ~1HP.

@ cHaRlEs I don’t care in the least bit if buddy here wheres a helmet. Yes the scooter is 2 in off the ground, his head is ~6ft +2 inches off the ground. So if one did hit their head it would be quite a bit higher then 2 inches, unless the ground came to you…

Sounds like you hit your head pretty early on in life judging by your grammar.

There is a time and place for helmets, but that is my choice, not yours or anybody else. I wear the protective gear I feel most safe with almost daily ranging from knee-pads for skateboarding, to a variety of pads for paintball. I hardly think you or anybody here getting all preachy is going to change anybody’s mind on the matter.

I am now done with this conversation.

Would you do this without a helmet? Probably you are not here in this world anymore to reply.

what is with all the helmet preaching?
Thank you for the advice mother(s). Please get off your soapbox and let me and everybody else in the world decide if they are going to wear a brain bucket.

Yes, very nice of them to lend THEIR equipment.
