4 years ago I developed an e-scooter ESK8 mix together with one of my suppliers. I call it Driftboard, because it has just one solid rubber rear tire, which is very easy to slide around using the brake or throttle on loose ground.
It had a 15A FOC controller, 450W motor and a13S3P 18650 battery. I had a range of about 30km and the top speed was about 45km/h with an acceleration form 0 to 45 in 2 decades.
It was fun carving the shit out of it and I enjoyed it for short commutes during the summer.
With the appearance of the FS 75100 and better battery cells available, I decided to give the Driftboard a refresh. I thought the 75100 should be the perfect match, since the form factor of the VESC housing is exactly the same as it was before and there are still the same options for the lights that are build in.
So I swapped the battery to a 20S3P P42A with a 20S ANT BMS and the 75100 with Metr Pro.
I also changed the thumb throttle display to a twist throttle and a smartphone mount. The top speed is now 65km/h and the range is more than 60km with the same riding style.
The biggest clue is that the 75100 has 2 UART ports, so it is now possible to use it with an RC as well.
So if you want to ride it more like a regular e-scooter you can use the twist throttle, but if you want to rinde it like an ESK8 you can collapse the stem and ride hands free. Due to the steering linkage on the front wheels and the single rear wheel, it is a total different riding experience.
I’m not totally done yet with the project, since the VESC needs a better cooling solution and little more fine tuning, but the first rides were fun and enjoyable. I might try a larger motor as well and the 75100 V2 to get more power out it, but so far I wanted to share some of the first experiences with the board.
Here are some pics of the old battery with the old ESC and BMS vs the new ones.
