Scootabot

Post by Emoto » Jan 27 2018 4:40am

Been Designing this one for a year now, researched all components , bought some parts , and then thought no ill do a kickbike.
But i think this scooter will be a lot cooler 8) more power full.. but of course a lot more fabrication / designing and a generally a bigger torture :| .
So here is the brief as of now.. full custom aluminum frame - with alloy mag wheels and custom alloy hubs with 13x 6.5 '' tyres
Reduction drive with big block inrunner type motor [ still to be decided ] and just to make it harder, BELT DRIVE for a more silent ride.
And to add to the quieter theme sine wave controller . And lipo
Let the build begin..

Thanks Gaffer i will.
Ive been in deep thought the last couple of days ,
One thing im going to change is the size of the 6 m5 hub bolts to m6 just for a bit of security.
Also playing with cad and plan on a custom alloy 44mm bcd to 5.1/4'' bcd hub to pulley adapter to mount kart toothed pulleys :)

And after doing all dimensional calks i was just about to start on the main frame fabrication [ no suspension] and thought bugger it i would really like some rear suspension to soak up those small vibrations , especially as im going to all this trouble may as well , its going to be real tight but about 4'' of travel should be ok . with a nice little rockshox air shock .

Design update..Looks like rear suspension is doable, which im super!! happy with / has to be comfy-ere :D -- ill have to take a hit on main frame size but should still be able to get 20ah of 60v, plus a controller and stagger the air shock on one of the swingarms arms.

The deck will be wide enough to stand both feet parallel facing forward [ cruising ] and ill have a kick plate at around 45 deg at the rear, so i can have one foot forward and other on the rear kick plate which will be a good solid stance for hard acceleration ect also covering the rear wheel like a mudguard .

Ive been struggling finding 30mm belt torque nm ratings, so i spoke to my local harley shop and they use 25mm on one of there nearly 2lt bikes
So thats good enough for me as my power should be around 8/10kw ... 30mm belt it is .will go over design this weekend and hope to start on main frame next week.

Did i say it was going to have rear suspension :lol: Ive flipped on that idea , i only want to ride on smooth cycle-ways and this for me will be a upgrade in ride comfort from my eboard so im betting the bigger wheels alone will achieve this.
This way i get this project moving, and if its as much fun to ride as hoped i can always do a different one later.

Just spotted this one, those wheels are smart if the rest of the ride is up to those standards then it will be a stunner.
The tyres have plenty of sidewall and compliance should be easy eniugh to use offroad, Best scooter I had was with small 4inch wheels and loads of ground clearence, it was great fun on dusty tracks and beginner downhill paths etc so I'm making it again with more beef.

Unfortunately no tangible progress on this , i had a welder lined up but this guy has strung me along for 6 weeks now and ive bailed as he is unreliable . so waiting on another now to slot me in, this is sometimes the reality with custom builds but everything has a price , so ill keep plunging at it .
On top of that im looking at doing a big change in life witch includes moving so this is on the back burner when spare time allows.. still keen though.
Ianhill good to hear it was not to bad off road .[ ill have around 4'' of clearance ] i wont be doing anything like that just the odd squirt on the beach looking for fishing spots. :D those fat tyres should do the job nicely .

Finally my welder did some welding , quite happy about that :D , this is stage one on the main frame .
Not a bad standard welds look good he struggles on vertical with tig [ normal as tig is not the easiest ] , this gives me some good insight for next stage so we will focus on improving this.
Have designed 90% of the next stage, got headset bearings ect .
One nice thing about using extrusion is you have a good base for measurements and alignment.
So now i have something to play with.

:mrgreen:.... Here is the stator of one of the motors im hoping to fit, rad in runner magnet config .. no chance these flying off, as some have.
Just waiting for magnet width and kv specs .

Its been a long time Now and no reply on the specs i need for that motor :banana: .
Lots of measuring / designing on the front end pretty much finalized now , here is the alloy fork 90% there ... a bit of plate fabing / welding ect.. ive now got a new welder to try , still yet to find the right dude.
Sourced some nice long stainless bolts for the wheel axles , and will be getting some custom alloy axle spacers made soon , no expense spared :roll:

Today Small steps, ive finished the reinforcing plates and cleaned all areas ready for welding, now lets see how good a job the new welder does , fingers crossed.

I get why aluminum is the chosen alloy. But with the difficulty of welding it, I often wonder if 1 mm thick mild steel lasercut template strategically folded would not provide enough rigidity. Sure welding thin ms isn't easy either but it can be done, not relying on specialized welders for the job.

For sure ali welding is a bit of art form and outrageously expensive if you get the wrong people ... but well wort the effort in the end for me, Among other things i love machining it .
This one i might not paint ,Im thinking leaving it raw or i might just polish it and no worries about rusting as i hope be riding on beaches.
