I Blew It Up! - Scooter Episode 11

In the process of trying to build an ever more useful and awesome Razor E300, I burnt it all down to the ground.
Expect video of the testing regime that led to this in the coming months.

Ive just gone and watched the whole playlist of this. Absolutely love this series and now super inspired to upgrade my e200, which is basically a smaller e300. Great playlist and cant wait to see what is coming up next!

[@alexcampbell7356]

Bro. RIP. I watched your scooter vids like 3 years ago when I was trying to build a Razor scooter chair.(Since scrapped in a move). Hope you get back on the road soon! Best wishes from Oklahoma!

[@WhatUpTKHere]

Thanks pal!

[@samsbigshow9081]

Thanks for the episodes of the e300 customizations, loved em

[@WhatUpTKHere]

No problem - more to come!

[@kabevis1]

Oh no TK! That just sucks. I too just toasted my stock motor running on over-volt (36v). I just received the 500w but haven’t installed it. Not a lot of hope for me after watching this. Oh well, I’ll try it anyway. Consider using a car alternator converted in to a BLDC. They are a few “How To” videos on KZbin. Going to try that myself if my new motor does last. Good luck bruh!

[@WhatUpTKHere]

Yeah those stock motors are weak sauce when overvolted, burnt two out myself now haha. Cheers homie!

[@lestergranger1685]

I think cooling is the key here... I was thinking of banding a ton of strips of metal around the motor and then bending them out the back of so they were like fins cutting through the air. Maybe even a cheap temp prob and display could be in order(?) Also I have learnt that having a lower gear ratio also put tremendous stresses on the motor as well as the electronics, SO, maybe drop your top speed a little and up the ratio. It would see an extension in life for all components. I'm still rocking my 1st standard 300w motor but was thinking to downgrade to 200w but keep all the other mods just to extend the range and add as much cooling as possible. Everything is a compromise. But at 200w I would be pumping in nearly 400w vastly reducing my current consumption and drain on the battery. I'm down from 90kg to 83kg now so losing a little weight helps too (side tracked research into F1 drivers) Keep up the good work.. and as you are now burning through them I believe NOW is the time to go brushless. its WAY more efficient so you should see perks across the board for speed, range, acceleration... good luck with it all!!

[@WhatUpTKHere]

Very cogent points, particularly on gearing!

[@lestergranger1685]

@@WhatUpTKHere I think the key is high ratio gearing on a very high rpm motor with added cooling. The way you're currently doing it you will burn through many motors. Hence the reason i prefer the overvolt method. But this has many of it's own problems. So I suggest brushless as we can achieve the high rpm with long gearing and still stay, relatively, cool.

[@djartbeatsentertainment]

Man that sucks, R.I.P Razor e300! Hope you get back on the road soon! I modded an e300 and already went through 2 motors already lol.

[@WhatUpTKHere]

Ha, #justscooterthings

[@russsayscut437]

Cool show dude, I'm doing a similar thing on my channel with my electric scooter. I've modified my battery to the same as the Mi M365, upgraded the motor and fitted a disc brake after watching what you did with yours. thanks for the inspiration dude, wish me luck.

[@WhatUpTKHere]

Cheers bruh! Sounds like some solid parts ya got there, good luck with the build :D

[@paulkuvener6940]

Hiya TK! Mate I have used your advice to build myself quite a mean E300, running an 800w controller & variable throttle (after killing 3 stock controllers, and also nearly myself at full boar when the fets' died lol!) and a 36v 350w motor. For power I love saying it's 'powered by Samsung' lol, I made 2 x 5s4p battery packs connected in series out of cells from 4 Aldi battery packs (which some people may not know are actually Samsung 20Q 2000mah cells) giving me a 10s4p 41v 8ah pack (Yeah yeah ok, 37v lol). Btw I did it like this because I am a tightass and didn't want to buy an expensive charger, I just use 2 x Aldi chargers that I got for 10 bucks each. I changed the charge port to a 4-pin, with 2 wires going to each 5s pack and both chargers connected with the one 4-pin plug. I get a range of about 14kms , which to me is bloody brilliant. So yeah, TK I just wanted to personally say 'thankyou' mate, your videos have been an enormous help to me and I would've been fu.., umm I mean 'buggered' without them! (Every single time anyone asks I always say 'there's this guy on KZbin called TK...... etc etc lol) Oh 1 more thing, mate this latest video is painful to watch, I can smell that motor from here! Your place must smell terrible! ... I was in the shit with everyone here for about 2 weeks when I cooked my motors lol!)

[@WhatUpTKHere]

That’s huge range for a 8ah pack! Glad you found the videos helpful, thanks for spreading the word :D P.S. you are not wrong about the smell, I tell ya what

[@paulkuvener6940]

Wow TK thanks man, I'm honoured you actually read me lol! (Oh yeah btw I was 'channelling my inner used-car salesman' re. the range lol), i arrived at that figure by measuring the exact route I take to work and back using the rather intuitively titled app 'Map Measure', which is just under 14k's. However, It slipped my mind that it was actually you i was telling, and I failed to disclose the fact that that route contains a few 'sections of continuous angular declination' (Lol). If you factored in positive gradients and stop/starts the figure would be more accurate at around 11-12 k's.... My apologies there TK!

[@TheCaffeineRacer]

Shame, I think I will try fit some pc cooling fins on my motor case. Plenty of motors on bangood or ebay. U think it had a build up of dust?

[@WhatUpTKHere]

Good idea. I’m exploring cooling solutions for the replacement.

[@omernomer7429]

Hey, I just wanted to thank you so much for getting me into this hobby! I've welded up my own scooter and did all the electronic bits and now its absolutely killer. Thank you so much man! Also, when are you gonna make an update video? Id love to see it!

[@WhatUpTKHere]

Later this year, but current focus is on the Solarboi rover! Thanks for watching :)

[@RSmerlinRS]

could try a 1000w brushless but itd need a battery that can deliver the power. Motors about 100 bucks and banggood has 'ZOP' brand 6s 8000mah (30C?) lipos that are also about 100$ea. problem is these batteries wont fit well in the E300 unless you mount a battery on top of the aloy deck. for 12s lipo you could do 3x 4s lipos, have 2 in the normal spot and the 3rd above the deck. really its best to source a bigger framed scooter unless you're cool with chopping and welding the current E300

[@WhatUpTKHere]

Yeah it’s tough, because I spent $400 on the 36V 18ah battery because I want big range, and it’s just a bit limp in current delivery. Reckon I’ll stay in the 500W range but go brushless, rather than switch back to my old high power batteries. Short range just isn’t quite satisfying enough anymore.

[@RSmerlinRS]

@@WhatUpTKHere if you could somehow mount 2 of the 500w motors and have them both power the same wheel. Two speed controllers, won't be too hard if they're still brushed. Your battery could take it

[@WhatUpTKHere]

Nah, 2 500W motors would draw 1000W total and still be too much. Tbh 500W is plenty of power for now, but if a big pile of KZbin money came in I might consider a dual battery system for double the current and range.

[@RSmerlinRS]

@@WhatUpTKHere or in series for 72v :) make it shred tyres. What ever you do, can't wait to watch

[@WhatUpTKHere]

RSmerlinRS I like the way you think ahahaha

[@grandtheftauto1233]

I missed this one. Been keeping up for a long time now! Great video TK. I am surprised the MY1020 failed. I believe since you have no current limiting anymore you might be putting excess current into the motors than they're able to output. Personally I highly recommend a Kelly Controller (Kelly Controls). It is programmable and works very well for my dune buggy. Love the vids keep them up! I recently got a e300 as well and the modding has already begun

[@WhatUpTKHere]

Good advice! I’m tempted to switch to a brushless MY1020; the brushed version always stank after a ride

[@grandtheftauto1233]

What Up TK hear those 1400w brushless kits are pretty good. When you get that new controller. Mod the shunt with a little solder and you’ll be set! Little extra oomph and reliability! Can’t wait to see the next one

[@mondude9754]

You should upload the video where you add the new battery and burn out your motor. I am also having motor issues I have a very similar motor but with mine I left it out in the rain and one of the magnets came unglued

[@WhatUpTKHere]

That sounds annoying! I have also broken a magnet before, it sucks

[@Velktron]

It not only let the magic smoke out, but the magic carbon as well.

[@WhatUpTKHere]

It stanks fer sure!

[@mkat_551]

I'm super torn, on one hand I want a scooter to make it goes fast and have to ride around, but on the other hand I feel like you spent about $2,000 doing all these mods. Is there a list somewhere of what would actually work together without frying everything?

[@WhatUpTKHere]

Probably just go buy something fast if you don't wanna experiment :)

[@stevenmarquez4476]

Shame on the motor failing but should provide you with plenty of scooter modding content for the future.

[@WhatUpTKHere]

Haha, indeed!

[@jayracz701]

I am almost done with my mods to my e300. It looks great. Hopefully it performs as well as I hope. I don’t make vids. I would like to send you some pics of my build. Maybe they would inspire you to revisit this series?

[@WhatUpTKHere]

It’s not so much inspiration as time! SOLARBOI takes what little free time I have outside my two jobs, but I do have plans to resurrect the scooter one day! Show me your pics on Twitter! (@whatuptkhere)

[@jayracz701]

What Up TK Here I don’t do twitter or Facebook. Believe it or not I am social media free. Have been from the start. I comment on KZbin. That’s it for me. E mail me if you want. [e-mail].

[@All-rc804]

Hi do you know if i can use a brushless speed controler on a brushed motor?

[@WhatUpTKHere]

Some you can (like VESC, I think), but mostly no.

Thanks for the update, your mistakes will save me a lot of money :P

[@WhatUpTKHere]

Ahaha, tell me about it!

[@mjp0815]

Just buy two cheap 10 inch hub motor wheels. 2wd scooter, sorted.

[@WhatUpTKHere]

Would be a cool way to do it!

[@gyromatical]

I chopped a kids bike fork onto a Razor. It's way too high up and basically messes with your wheelbase and everything else. You'd need to extend the rear or just own it and live dangerously ... like, Evel Knievel style

[@WhatUpTKHere]

Gyromatical ahah that’s mad

[@shadowofsunshine6019]

So what will do with the scooter now

[@WhatUpTKHere]

New motor, more range!

Rip. You were a good scooter. Those motors are decent but yeah you abused the brushes also lol. Check out HobbyKing

She certainly stank after a long ride, I tell ya what hahah
