ATC 70 Single Speed Automatic

[ICS Vortex]

Hey guys,

I'm having my first child, a girl, in February! It may be a bit early to start thinking about getting a three wheeler for her, but I'm really excited. I think first starting out, it would be best to get her something that is fully single speed automatic. It's my understanding that the ATC 70's are 4 speed. Are there any known easy swaps for something that is fully automatic (single speed)?

I'd also be open to the YT60's or ALT50's since they are already fully automatic (single speed) but they seem to be a bit harder to find in my area.

Thanks for the input!

Just leave it in first gear and use the throttle stop .

I wasn't aware that they had a throttle stop - would it be okay to leave it in 1st gear for a prolonged amount of time?

I did similar with some TRX 90s when my kids were small. I put them in second gear, removed the shifter and used the throttle limiter to screw to about 10-15%. When they got older he loosened the screw gradually and the. Eventually put the shifters back on , then upgrades hahaha. https://uploads.tapatalk-cdn.com/20251018/34ecd96db8646b12dd9166c3de9c2a73.jpg
