The next step up from a bird 2 scooter that is quite a bit more powerful suggestions please

Been there done that. Remove the stock controller, vent the motors side plates. I basically drilled five equally spaced holes, I use just step drill bit too increase diameter to a 1.25". , you'll see why I say five holes once you take the side plate off. I didn't use the carbide burr to basically manually mill out more metal.
Venting the motor is essential, You're not going to get good performance without it and you will burn the windings.
After venting I've never had issues with dirt or debris getting inside. I use common sense but I've even run the scooter up to the store but it was an inch of snow on the road. Slowly of course.

I used the stock battery, bypass the BMS discharge.
BMS still works for balancing. From here you can add either a VESC based flip sky FS 75 100 pro V2 or a FS75 200 pro V2. You're going to need to learn how to solder and you could have need electrical knowledge and mechanical knowledge/ability as well as computer skills.

With the stock 10S battery You can get a significant increase in performance with a vesc controller. Field weakening will get you a good boost probably up to about 30 miles an hour.
But to Go beyond this you going to need to increase voltage. I'm running mine at 20S. You can basically add another stock pack in series. I separated the second stock pack into two pieces stacked them on each other so they fit between my feet on the deck. Guys with e skate mountain boards place their batteries in a similar position. It really doesn't cause problems. I don't charge my battery's conventionally I use a large RC charger which accepted balance taps. I would not recommend doing it the way I do unless you understand what you're doing.


With a stock motor and a 75 200 pro V2 tuned close to perfection I'm able achieve 55 mph flat road with no tail wind. The scooter is surprisingly stable. I don't keep it at full throttle for that long. I don't really need it because 55 miles an hour is enough. This is achieved With the stock motor vented as I described. I'm pretty aggressive with the throttle. It's a lot of fun the torque is mind blowing considering it's the stock motor.


That said it took me a while to figure all this out over a several years . many motor controllers burned, I've went through many motors Figure it out how to tune the motor took quite some time. I finally got a good setup which I've used for about a year and a half without problems.
. I also have a vast amount of experience with electricity , Hi capacity high current lithium batteries. motor controllers, wiring methods. Been an electrician for much much longer than I'd like to admit and I've been into high performance large scale electric RC aircraft basically ever since high current lithium polymer batteries and brushless motors were co introduced back in the mid-2000s. With all this experience It was still a bit of a learning curve for me.

Awesome, heaps of knowledge and experience hope to get there sooner then later
