@markciccio I’m curious, how much does the gREVel frame, front triangle and seat weigh? Not sure what it weighs but the Cruzbike S40 is probably the closest thing - it would be an interesting comparison to the S40.

How heavy is a Nuvinci? It might make the steering go funny.

In action
A couple things that I see :
1. The seating is too high, probably should make the seat tube more angled
2. The seat is very short, need it longer so I can rest my head and back
I havent test it yet as Im busy and I had someone else make it, the guy in the video is the maker and hasnt rode a FWD MBB, so it isnt that hard to start ride it. This is witha very high seating and very laid back seat

Test ride it and note many things
1. The top tube is too long and the poaition of the seat was a bit too far back
2. The seat was too much lay down while I wanted a more upright one
3. I wanted handlebars to directly be on the boom and not attached to a stem
4. Usual handlebar setup hits my legs so it should be turned up
5. The attachment of the boom to the headset of the fork is too short. No spacers make it rattle and having it on bolts mean more effort when yoi want to change the boom length.
6. The boom wasnt properly holed so the clamping cannot be tight
7. The boom was too long as the seat was too far back
8. Changing the crankset too smaller ones had a problem as it didnt clear the boom and fork attachment
9. The seat tube and seat stays could probably be modified if he wanted to make another Cruzbike Homebuild
10. The shape of the seat tube is an angled L while Cruzbike usually has this U shape.
11.should bend the handlebar so the drops face outside more and clear the knees/leg
12. The weight. Even the road bike where I took the components for was heavier. So I think it could be under 13 kg. The maker stated he used robust steel tubes so it is rather heavy, but if Almunium or chromoly tubes for bicycle is used, it could be much more lighter. Problem is money, sourcing the tubes and the market
13. The ride itself was good, didnt feel the road imperfections too much as I ride around the housing complex. I think the head tube angle and the positioning of seat stays play a big factor. The seat stays does not point through the axle and the angle of the fork angle means bumps are smoothened
It also turns head.
The maker then made several modifications which could be done and noted my notes for improvement for the next. I still want a bigget sear though, this one is short and narrow
