Got one of these for my 5 year old, 20£ guy said it just needed charged. Got home done a few tests turns out the board was kaput. Followed your video and done the bypass and it's now flying. Not bad for 20£. I was about to wire in my own relay then found this way much easier. Thanks a lot. I've no charger for it so hopefully it will still charge through the port whenever I get hold of one cheers buddy..

I found an E90 in a dumster today with a cracked battery. I was looking for a way to test it out with a benchtop power supply. Your bypass idea was great and was perfect for allowing me to test it out, it worked! Thank you!

*Came in today and my friend and I both rode **Latest.Bike** Scooter around for about an hour. Was lots of fun and didn't drain the battery much at all!*

Just did this today, worked like aa charm! I got an e90 out the trash, building a 24v cell to get some run time out of it. HOWEVER.. You can mix up two connections and as soon as you flip the switch it runs wild! Lol other than that good show!

Great if controller circuit knackered but as it is for an 8 year old, the brake switch will now have no effect on cutting out motor. Great stuff though 👍 my issue is no power when button pressed, turns out the relay isn't getting the ground, so like you I gave it a hard ground and the positive side of coil now has the yellow wire going to it, that way the button does the job and the foot pedal switch.

Thank God for people like you. Saved me at least a few days just testing to find the right process to bypass that stupid 3-5v "safety start".

good video helpful i found just using the black wire short works fine off the button did not need to move the yellow wires could be luck on my part but thanks

Ok i did exactly what you did but now the scooter goes full throttle as soon as you turn the pa power on. What did i do wrong

[woodworks]

The kickstart feature on this scooter I think is dangerous. As your kids got one leg behind, the power kicks in at full power and sends them flying. It's a decent basic scooter but I think I'll be changing the speed controller for an actual normal speed controller with a real thumb throttle n if I get carried away, change the batteries for lipo to make it lighter and increase the range. I love to get a cheap one and make it better than just go out and buy an expensive one. Especially if u get a 2nd hand cheap one or find a broken one. They are so simple to work on.

Great video just use larger gage wire for powering the motor otherwise it might melt

[csabi]

Well, I just did exactly what you did now the motor comes on as soon as I connect the battery, speed switch is no longer functional.

I can not here any clicking from the relay on my e100 but as i said below the light switch on off switch lights up red, could this be lack of charge its been stood and was working and must hold charge as 8 months no charge it still lights up and it has been used a very few time his little one did not like it, any feed back i would be great full.

How do I just bypass and make it faster is that the black cable? Adding more voltage right

[haz]

I have got the razor 100 with the trottle turn swich on the handle bar, i switch it on the light come on red, i have tryd the push start but nothing, could it be there is not enough power in the battery as i am waiting on a charger, i thought it would still start even the battery is low.

Question! Can we get the Razor Sonic Glow Electric Scooter (USA) to go faster? I got my son one for Xmas and one of his friends parent's got their son a "freaging SEGWAY! scooter" and his friend's scooter goes 30mph and SMOKES his fancy light-up scooter. He's getting frustrated getting left behind. I can't afford a Segway scooter for my 9 year old right now! I have 2 adult daughters I'm trying to help get their first cars and even used car prices are through the roof right now! PLEASE HELP ME if it can be done!

Hi, I'm trying to bypass the kickstart feature. Is that done with the black wire shown in the video? What are the other 2 thin yellow wires for? (I'm trying to make it like in the video where you can press the button and it will automatically run the motors without having to manually speed it up first via kickstart in order to activate) I have the e90.

[kennywatson]

I've got an E100 scooter, seems to have the exact same control board, however when joining the same 2 as you I still get clicking from the relay. Any ideas?

[reecewood]

Can one just take the speed controller out, or is it needed?
