My old mechanical brake/wired remote just for laughs

It honestly would not be that hard to couple a mechanical brake with a PWM remote. Just split signal to a high torque servo that actuate a brake caliper. Same way all RC cars do it. Donāt really see a point other than for some AT boards on steep terrain.

just wanted to say that gear drives (and also chains) are very efficient. Most the friction in our drives comes from the grease and the rubber seals used to keep the grease in and the dirt out.

I would be curious to see how much energy is lost in the belt and pulleys vs how much is lost due to the eddy currents in the motor.
I really need to build a test rigā¦

Just a random comparison point, lots of times when Iām riding with friend, he in his bike, and we do this test on small inclines, for my board the drag is almost the same, we go down the hill side by side most of the times

I feel that everything discussed in this forum has already been tried out by our brilliant French baguette engineers.
First this
Then about this topic:
A video from a french FB group showing this concept of a skateboard wheel acting like a bike.

I have the mbs equivalent brake system on a manual mtb.
Feeling the increasing resistance in the throttle as you brake is a refreshing level of feedback, Iāll say.

Plus, brakes on the front where they should be.

Police here sorta allows exactly that, but instead you accel yourself and it cruises a bit and then goes to coast to then repeat.

Thatās gonna be a no from me dawg. 
Whar about a mechanical brake assist for RWD boards. The mechanism can be simple and compact, take a belt pulley shaped bell thing attached to each wheel, except the outside is just smooth and the inside has brake tracks, the actual brake attaches to the truck and expands from the inside into the bell. Basically how drum brakes work.
Would be compatible with all wheels that uses that core etc, just like pulleys.

Yeah, but then youād have brakes on the rear, and while (brakes on the rear are) no different than what we have today, itās also no better (in terms of braking force / traction).

I meant installing it on the front. The rear remains as regen. It was just my idea to make it compact and more universal to different trucks/wheel combos.

Sounds good.

I am definitely well aware of how the implementation is done on a conventional mountain board. I am curious how one would do this without being forced to have both hands tied up - one for brake and one for electric control.
Otherwise the implementation is honestly not so difficult - until you get into 4wd boards and effectively remove the access and ability to use the mounting points for the front and rear brakes.

I would assume a high-torque servo and ADC Iām conjunction with a manual brake kit, but that does nothing if your VESC fails.

High torque servo running on its own power converter using split PWM signal from the receiver? failure of vesc does not affect input and power to servo control

Someone on builders has done this already.

Without using PPM or ADC from the VESC you canāt control the break force with a throttle curve. Plus, what point do you power the RX from, how do you control power delivery? This as a solution seems riskier than just using the brakes from the VESC like 99.999% of people already do.
