starter motor powered bike video compilation

[hiruna1]

WTF ? this has a great acceleration than my 70cc :S LOL

[wweraw5678]

how many tooth flywheel

[pontoontodd]

@wweraw5678 153 teeth, see the description on our other starter bike video for more info.

[mptrax]

muuuwaaawaawawahahaha no controller, just on/off switch !LOLLL !

[LUVHERB247]

that thing got sum torque!

[backyardsounds]

Due to the tight winding on the motor, wouldn't it burn out quickly? Just curious. Also, why didn't you just go with a regular electric motor... :) Neat stuff.

[pontoontodd]

@backyardsounds they probably last about 100 hours @ 12V. the flexplate makes the drivetrain cheap, simple, and reliable.

[poweressen]

have you tried controlling the amps using a lm555 and varying the cycle duty form 0 % to 100% using sinewave dc pulse? i am seriously thinking about a starter motor and a 200ah 12v battery ^^

[DmakAttack]

OK..DEATH TRAP!!  ha ha,,,Looks like a fuckin BLAST!!

[djfantom205]

yu know this guy has a video titled " water cooled car starter electric bike"

and if i do this I wont have to ask my dad to take me to atouzone every 15 minutes

[pontoontodd]

@djfantom205  they normally last for months of hard use before burning out.

[pilavideo]

i dont knew that can wheel :D

[ipissed]

you can get a 12v potentiometer for boats and such for a throttle

[hoorsec]

that must be a dodge starter rreeeeeereerrreeerrererreee

[pontoontodd]

nope, big block chevy

[djfantom205]

@pontoontodd I knew it

[universalmoor]

awesome

[ratheads]

LOL, I made a 3 wheel standup cart with the same gear, I found out real quick that a starter motor is not made for this....FRY !

[pontoontodd]

they usually last a few months if you ride often, when it burns out just take it back for your free replacement!

[dratorent]

great thing

[DDandtheking]

i was thinking of doing the same thing on my bike but i was wondering if you needed to use a car battery for the starter motor, or possible something smaller?

[pontoontodd]

anything 12V will work, just won't last as long.

[airsoftmaniac1988]

i want one of those motors where could i get one

[2605830]

lol at torque

[Ninjasmoon]

Wheely bar

[chevyloverguy1]

was that grinding ???

[pontoontodd]

the gears make a lot of noise, especially when they're not aligned quite right.

[hellspawndarkangel]

hey just wondering, i saw a thing on the internet on how to MODIFY a starter motor for something like what youve got here, i was wondering if you modified the starter at all, and did u use car batteries, if not what type

[pontoontodd]

just normal starters and car batteries.

[treborly]

i thought it was high torque low rpm. How come you geared it and it still went fast?

[pontoontodd]

it uses a standard flexplate that would be on the engine. so you get a lot of torque multiplication and it gets up to a few hundred RPM.

[uclarge]

waaay too much power, did he use a controller or resistor???

and i guess ice doesnt help

[pontoontodd]

it's just on or off.

[uclarge]

sweeeeeeeeet

[DoctorPlutology]

A ha ha ha that looks amazing! I have a pretty big starter motor at home and a crap bike, plus an empty summer ahead...

[svenskakr4]

I hope u used an optima gel battery.

[k0ent]

for how long can you let it run? and how many AH does the battery has? cool design

[pontoontodd]

20+ minutes in the snow. 60+ in the summer. half that with the single battery.

110 minute reserve capacity.

[xXxmidgexXx]

I would cry if i were the battery

[silverska8er]

how much did the motor cost?

and how much was the gear ratio? 72-12?

[pontoontodd]

$70 at autozone w/ core charge and lifetime warranty.

standard 153 tooth flexplate, starter pinion has maybe 7 teeth?

[silverska8er]

thanks

that has alot of torque lol

[bicicletaeletrica]

Gosto de ver veículos elétricos em ação. E quanto ação hein!!!

[Rottao]

Que gambiarra do capeta. Se eu tenho uma bicicleta é porque quero pedalar, quando não quero pedalar ando de moto.

[timrocket2008]

I bet that will pull you up a steep hill with no problem!

[lakecharlesfrankie]

Is that a basic flywheel you are using as the gear? Was it easy to mount or did you have to weld it into place? Can you give us a few ideas on how you put it together? Looks like a racing machine to me. Good job.

[pontoontodd]

it's a flexplate for an automatic transmission.

we machined a hub for that which we welded onto the bike wheel. the one on the BMX bolted through the plastic wheel.

there is a fair amount of fabrication involved in the motor and battery mounts.

[Cr4ckCoca1n]

looks like fuckin fun!

[SAIDARK7]

the bronko!!! XD

POWERFULL JEJEJE

[999benhonda]

what did you use to "switch on" the power? is it "on-off" or does the power come on gradually?

[pontoontodd]

heavy duty push button (on-off)

[RoboTekno]

best idea ever! haha

[ashishrd]

That's a lot of torque...awesome video! I thought starter motors couldn't be used for continuous use. Do they heat up?

[pontoontodd]

it gets hot, but when it burns out you just take it back to autozone and get a free replacement.

[universalmoor]

lmao

[djfantom205]

@pontoontodd are you kidding

[talbertnz]

thats so cool!!!!

[fallingwater]

How much do you pay for the starter motor(s)?

[pontoontodd]

$70 w/ core charge and lifetime warranty. consider it a one time cost.

[donnyjayw]

How long till starter motor burns up?

[pontoontodd]

a month to a year depending on how much you ride it.

[donnyjayw]

Thanx, great bikes!!

[gorbache]

Green practical transpo right there...

[DJBJ24]

can you ride it continuously, or would the solenoid overheat?

[pontoontodd]

you can basically keep going until the batteries die.

[Hanowair]

Nice work, how long does the battery last?

[pontoontodd]

20+ minutes in the snow. 60+ in the summer. half that with the single battery.

[SomeoneSmarter]

Nice drifting! Keep it up

[mixer1dotgeo]

I love shit like this! Awesome engineering! Post another vid after the snow melts (If you're still alive)
