Re: E Kart sprocket I need your help

Kart axle sprockets are normaly mounted on a “sprocket carrier” which has the axle bore and key fitting . The sprockets are flat with a 6 hole bolt on fitting to the carrier. #40 may be a bit light for 23kw max,..i would plan to use the 219 series chain and sprockets that most racing karts use... a...

Re: E Kart sprocket I need your help

Why use 428 chain? Even if you already have a 428 rear sprocket it can make sense (in the long run) to find a front sprocket and rear sprocket combination that's just bolt on. Front wears more, will be replaced first, so if you need to adapt something every time then it can be a hassle. I'd buy bot...

E Kart sprocket I need your help

I built an E-Kart but I am finding it hard to find and figure out what gear ratio that will give me a top end of 60-70mph. The only sprocket I am finding for my motor is for a roller 40 or 50 chains. I wanted to do 15 teeth sprocket (motor) and 25 teeth on the axle. The problem is finding a 428 spro...

Re: Alltrax vs Curtis NEED HELP

If both controllers are rated to carry the voltage you're using, then whichever one can supply more current could potentially give you better performance. The Curtis controllers I've used in the past featured automatic plug braking on closed throttle. That wasn't too big a problem when I used a fre...

Alltrax vs Curtis NEED HELP

OK... I'm building an E-kart to go at least 60mph. I bought an Alltrax SR72450 controller, sw202 selenoid, 5k throttle today. The problem is I will have to mount everything after receiving it which will cost more money in materials. Then I came across a Curtis controller already mounted on a heatsin...

Re: Electric kart

Where did you buy a 36 teeth rear sprocket? I've been looking to match your gear ratio to get the same speed as I have the similar motor specs as you.

Re: E-Kart Build I need your Help

Only problem i find with the pouches is that if one cell die it will bring all the other pouches down to 0v not all of them, ..only the ones in parallel...and that applies to any battery system. But the pack may well stop working , depending on the pouch failure mode. Correct but on my 18650 i use ...

Re: E-Kart Build I need your Help

With that motor and controller you can't have 2-3s to 60mph, the fastest you will get is 7-8 seconds. If you want 1h run time then you can't run your motor at peak hp either. I personally choosed A123 pouches at first because they have the safest you will get aside lead-acid. So average 4-10hp is 6...

E-Kart Build I need your Help

Hello everyone! I'm trying to build an E-kart so I could have a project with my twin brother. Yes, we are new to this but hopefully, this will get us well rounded. So far we have a Phantom Racing Chassis, Motor, and controller. The part I am having a problem since I'm new to this is finding what bat...
