tyslider,
What type of primary chain will be used in your gear box? Will there be a way to adjust the tension? Oil bath is the only way to lubricate a primary chain which drives some people to using tooth belts and sprockets to eliminate the oil issues. Good luck with the gear box adventure!

Looking good TS! (A lot better then my prototype)

Friction, I'm using High Quality #35 chain. There is a tensioner.

Dan, Thanks! I'd like to see your project too!

sounds awesome TS. Gonna try and master paint and post some drawings. For 2 and 4 strokes, I am just making a BB that freewheels and acts as a reduction gear, Like Ebikes.

Latest build pics and update

We are presently developing additional parts needed to complete a shift kit version of the Firebelly "Hard Box" all metal, locally manufactured and sourced green machine transmission.

Seals tightly w/ no leaks, Easy Low Maintenance!

The appearance is unsurpassed!

This is Truly a Gold Standard Product!

Thanks, Evan FBC

Hi Evan
The Hoot gearbox weighs a bit over 4 lbs
2" wide

The EZ motorbike transmission weighs 5 lbs 4oz
Prototype cover is 2" wide but can be reduced by at least 1/4"

The Grubee gearbox weighs 10 lbs 8 oz
Only 1 3/4" wide

Did I miss any of your competition?

The new Grubee belt drive does not have any published stats

How much does your transmission weight?

How wide is it?

I really do like the look of your box....
Are you offering any deal to dealers like myself?

thanks
