ever since i was 12 and saw some kids doing donuts in the infield, i was smitten. junior and senior high school were ALL about go karts for me. wish i had pics. i lived in mass at the time, and my favorite thing was getting the kart up to full speed on the snowpacked street and seeing how many spins i could do.
the passion somehow got lost after my first couple speeding tickets in cars, until i discovered ebikes.
anyway, back to the kart. i really liked the existing butterfly steering wheel, but:
- the brake lever was way too small for the power needed to pull
- i didn't want to have to rig up an ebrake switch on that lever to stop the motor when the lever was pulled
- the accelerator cable i had running to the back to twist a hall throttle was too stiff, not enough recoil, and wouldn't do more than half throttle w/o add'l mods
so i decided to bend charlie's old bike handle bars and flip them upside down like some other ekart steering bars:
then let luca try out the positioning:
this shows the brake lines, fyi:
took me a while to figure out how to attached the new handlbars to the stem, but finally figured out a bolting solution:
i paralleled 4 8s lipo 5.8Ah packs for 23.2Ah and put them in an old Zappy! ebike bag in front of the seat just to test it out. ran MUCH better.
a tad slow for me, but will probably have good speed for the kids. i think i'll put a bigger chain ring on the wheel to give high more torque, less speed tho.
i'll also mount the batts on the back - won't use lipo for more than first runs. still considering AGM SLA, but might look at some lifepo4 packs.
will need to wire up battery monitors/switches etc. fog lights?
