2nd attempt complete:
Update. Took it apart and started to clean everything up/tweak existing setup.
So far I’ve stained the deck, added threaded inserts for the enclosure and reverse mounted the motors.
Just wanted to share my first ‘DIY’ attempt. I felt this wasn’t complete DIY so I kept it in the general discussion. I took an eBay board with what I thought had OK specs (90mm wheels, 42v, 5.2ah, dual belt motors, nice looking enclosure) and retrofitted this setup to my trusty evo. I’ve hit 22mph and estimate 7-8 miles of range (haven’t run it out yet). I have another battery and enclosure with the same specs above that I plan to add in parallel to increase range and reduce sag. Having a blast. Hopefully purchasing a build kit board over Black Friday.
