motorhedfred the bikes are cool but you won't get much help from ( gasbike.net ) that's were I got mine from also the spare parts aren't available yet. I put about 3000 miles on mine last summer and the jack shaft parts do wear out and NO replacements are available. also the parts are in metric so off the shelf parts won't work. I did have problems with the primary drive see photos

Yes, and I'm no lightweight so I'm sure Murphy's law would apply. I'm guessing the alloy of that shaft could be improved upon and a good bearing retailer could recommend some superior bearings to support it, but that's not why you buy something like this. I prefer not to be a test rider for the R&D and warranty (or lack thereof) departments of either Phatmoto or the retailers. Speaking of retailers that sell Phatmoto Rovers, if any of them would like to step up with sweet group buy pricing you might get quite a few takers.

I see this as a way for those without the tools and/or mechanical abilities to experience motor assisted bicycling and a weakness like this is missing that mark by quite a bit.

I think that would be the ideal solution to the low top speed issue, except I believe it's a single speed in pedaling mode.

You can get a rear wheel that has either a cassette/multi speed freewheel or an internally geared hub. I wanna get a phatmoto frame, but they don't sell parts and I'm not buying the whole bike when most of the parts will go in the trash day one. I wouldn't use the jackshaft to keep the gearing on the left, I would do exactly what I suggested to you.

I might be concerned about the bearing in a bottom bracket kit. Even with the reduction from the sprocket sizes, that shaft will be spinning much faster than human legs can rotate it. The increased shaft rpm might be more than the crank bearings can handle.

It'll be fine. People have been running those bottom bracket kit bearings for years on shifter bikes. Mine is almost 10 years old.
