    I like it, to me it looks better than a folding frame.

    Current status of this build - BBS02B motor with a Lekkie 40 chain ring, Alfine 8 rear hub, 20" wheels with Schwalbe Super Moto X tires, 17AH tray battery:

    Throttle top speed gear chart (40 tooth Lekkie to 19 tooth SA sprocket, 20" wheel), optimized for the fifth (1:1) gear:

    This selection yields an easy on the motor 1st gear for steep hills and a wind at your back 6th - 7th and 8th are not used. I don't like to push the BBS02 motors hard for any length of time.

    Alfine conversion complete - I couldn't find the rim I wanted to use (polished Velocity Cliffhanger 20") through my normal vendors. Velocity had some and offered to build the wheel using my hub, so they got the job. I was going to build it one-cross with no interlace, as that's the way they're done in Asia (a mini-velo hotbed) - Velocity chose three-cross with the normal last spoke interlace, which surprised me. But anyway, now the bike is 8-speed Alfine with a shift detector:

    Oh, and Super Moto X 2.4 tires.

    Speed in gear chart follows - the range is too high by two speeds, but I'm going to live with it till I swap to the IGH:

    Another change to make - since there's no bottom stay clearance issues, normal stagger cranks arms will work fine and yield more cornering clearance. Such as the Shimano STEPS E6000 or even vintage tandem arms

    Here it is, and mostly done - kickstand soon, 8-speed IGH later. No sizing done yet, other than the seat height.

    As far as motor/chainstay clearance, no problem - actually more room than any other build I've done, and the chain line (Lekkie 40 chain ring to a 11-28 11-speed SRAM cassette) hits square in the middle of the cassette:

    Since plans are to fit it into cars and/or truck cabs, the bars are narrow and the pedals quick-release:

    On another BBS02 bike the Nexus 3-speed has been just fine, which aligns with other owner's experiences. In the second (hub-locked) gear it is particularly strong, standing up to severe power abuse:



    IF I can find a silver 32-spoke Shimano Alfine SG-S501 hub somewhere I'll go with it on the Neutrino build, just to have a little more ratio depth.

    I'm thinking about a short-haul bike that would fit in the back of an extended cab pickup - not thinking of a folder at this time, but who knows. So maybe ...

    Some component notes:
    • notice the three bolt water bottle mount - very desirable for tray batteries, and I'd just use the 17AH version I already have
    • gearing to start would be an SRAM 11-speed package, chained to the Lekkie 40 tooth ring - since I don't like derailleurs (especially on low-slung frames), the Alfine will come later as funds permit
    • depending on how high the stem spacer stack ends up, I might seek out a folding stem which would make stowing easier
    • the frame has a kickstand tab, but I've not seen what brand stand other Neutrino owners have used. For errands, it's handy to have the bike self-support
    • storage-wise, I think I'll go with a front rack with a decaleur, with a suitable, secured bag
    The Velo Orange Neutrino has a steel frame and what appear to be paragon-compatible sliding rear dropouts. It'll clear up to 2.4 inch tires.
