Tight Budget commuter/ adventure TBR7

So I have had a 2020 TBR7 for a few months and i want to look into modding it to commute on the highway and go off road on the cheap but i dont know where to start on mods and some ergonomics. I spend a lot of time on pavement but i still want to be offroad ready for when funds open up to got explore.

Welcome aboard! One of the first mods would be to change the gear ratio by swapping out the rear sprocket to a smaller sprocket to bring down the rpm's at higher speeds. Maybe a 40-42 tooth. I'm not sure what the TBR7 has on the front but a 17 tooth would be an improvement over a 15 or 16 tooth.

Front is stock 15... swapping to a 17 is almost like circumcision, should be done at birth as it makes the gearing much taller.

With the 15 tooth stock I'm in 2nd gear before I leave my driveway

If you swap the rear, I suppose you may need to make adjustment to your chain (remove links etc. )

15 swap to 17 required no chain alteration or replacement, stock chain worked fine ...for now ( cue in suspenseful music )

Ahhhhhhhh! Hurt reading about circumcision!!! 😂😂😂😂
I bought a chain cutter from Harbor Freight a few years back. It worked well...crude, but effective. I think most Chinese sweet street-spot gearing is 17/44, although I recall people here and on youtube mentioning going as high as 17/39.

17/39 would probably be dead sexy for street commuting ... I likey

Okay any other suggestions

Ok so gearing sounds like a 17/40 sounds like a great idea. Any recommendations on tires and luggage options?
