I can try 15:45 but the gearbox will get bigger

I think there is still some resistance. Do not know whether the V-Ring causes resistance. I will add a video later.

These are very interesting, but I’m not sure what the advantage is over the existing drivetrains. If you can build a gearbox that drives both wheels with one motor, you would have a TON of demand.

Looks nice and compact…

Could see a few advantages.

  1. If the gear is stronger than a belt you don’t have to worry about the belt breaking (now would be worries about gear teeth but depending on materials/lubrication/alignment this might not be an issue).
  2. Fully enclosed drivetrain means no chance for getting rocks into the belt, you could argue a covered belt drive would also have this advantage but I don’t see many of those.
  3. No belt tensioning issues this would likely be a rigid system

That said I would like to hear the OP in terms of reasons behind the design or what they see as the major advantages or any disadvantages compared with a more traditional belt driven drive train.

You can also fit dual 6374 or 6380 on Calibers with this drive system!

The advantages of the gearbox are like what @wafflejock said, no need to worry about the belt. But the advantages of traditional belt drive systems are more. It is cheaper and lighter than gearboxes. Because I just want to install the dual 6374 motor on Calibers, so I designed this gearbox. Although I can solve this problem by just replacing the Calibers, I think there are more ways to install the motor for everyone to choose. I hope that gearbox can create more cool skateboards through your creativity.

Sorry, I use google to translate my English is very poor :cry::cry: Morris

I disagree. Safety first. Debris gets stuck in belts and can lock the wheels. I’d prefer not to street my face. Belts are fine, but gears are safer. In more ways than I just described, just one example.

Definitely gonna need closed can motors for this, but the design is looking good.

Because the motor is closer to where debris shoots from the wheels?

Yes and cause the motors are so low and pointing forward. I guess you could point them out the backwhich might cool. Like spinning dual tailpipes.

Really cool! Awesome to see someone expand on @GrecoMan 's direct drive idea.

These are kinda rad. I’d be interested in trying them out when they’re available. Subscribed

Subscribed, definitely interested in purchasing these.

I changed the material of the gear I started to use 3D printing gears and there is a lot of noise. Change, although there is noise reduction, the noise of the thrust bearing becomes more obvious

This is the noise video of 3D printing gears and aluminum gears.

That’s pretty cool. Do you have any kind of timeframe estimation for when you might be able to start selling? Honestly I like noisy esk8 setups. People hear me coming and it makes it sound like I’m from the future

This week I have to test some km on the road and maybe start selling next week.

What are your thoughts on prices? Rough estimate is fine, I understand if you don’t want to set anything in stone just yet

If all goes well, the price may be around 200usd.
