Thanks Gary on the Rambler I have engine 10
Left 17
Right 10
Outside 44
Inside was 40 just switched to 36 and improved low end torque
Rear wheel 28-14 shimano 5 speed freewheel.

I'm using KMC HL710 from engine to shaft and shaft to outer ring and KMC X8.93 from inner ring to rear wheel. I had to file the engine sprocket and j shaft sprockets for the chain to fit but it didnt take very much.
You may need to switch back to a 40 on the NuVinci. I can't seem to find my paperwork, but I believe it contains info for minimum ring to cog requirements. I used the Ebike numbers. I'm pretty sure it was 40 to 18. I think you can go as low as 33 to 18 if just using leg power, but it's too stressful on the hub with a engine. You won't need to go that small cause you will soon see it is plenty quick enough with the 40 18.

Good to know, I have a whole new jackshaft on the way for Ducky and a couple 40t chainrings kicking about, so I'll start off with the 40 .

I’m too fargin’ lazy’da do th’ math, Chris, but what’ya think the budget is on yer ‘Goose? I think a lotta folks see some o’ these, an’ think they’re gonna be ableda build somethin’ solid fer $500-$600. I don’t think they appreciate the $$ and time y’all put inda these righteous rigs. Think this one’s gonna be up there, and it’ll be awesome! 👍

[EDIT] That’s an improper question fer me t’ ask, Chris. That’s really none o’ my business. I just think it’d be good for folks to have some understanding that — to be structurally and operationally safe/reliable — this takes time, sound experience, and WallyWorld ain’t ever gonna have these on the floor.

It's kinda hard to say, there are certain tools and such that you need so does that get added to the build price? And then there's a ton of sh*t I've ordered that either didnt work out or I change my mind so there's that extra cost as well. Plus there's the whole being my first bike and the learning curve and costs associated with that. And the biggest cost I think is living in Canada and having to pay ridiculous shipping costs on certain items and if im extra lucky I get to pay duty on it as well lol. I would say I've probably dropped $3000, easy on the Rambler so far, the mongoose is already over a 1000 with all the parts I've ordered for it so far. I probably could have bought an off the shelf build but I seen and heard lots of problems with them. If im doing over 50mph on a bicycle I want to be the guy that built and put it together so I know it's safe ( lol as safe as a 50mph bicycle can be). Last year when I got hooked on these dam bikes I bought a $200 engine kit and thought I'd be done. Lmao.
The price adds up really quick.
