    just read thru the thread and I am curious as to why the Luna 500C is not mentioned ? I see it on the Luna website in the BHSD kit as a option , but not here .... just wondering :)

    If you mean the standard wires that are on the controller like for the harness, discharge, speedo and gearsensor, yes. The controller has the same wires on the bare motor as if you bought the controller separately.

    Does your bbshd bare motor and controller come with the connectors coming out of the motor? Your picture doesn't show these. Thank you!

    Yeah it just so happens that only 52 is in stock right now but we will probably have more 48-volt shark later

    I found a link that explains or supports the use of 52v battery;

    I am getting close to buying a Luna Bafang kit. I thought I wanted a BBSHD mid-drive with a 48v battery, but I see as of today that only 52v batteries are offered as choices? I don't intend to abuse the eBike, but I read higher chance of burning out components being more common with 52v. I may sometimes use the eBike to ride distances back to my car and I don't want it to overheat. I am not concerned about burst power so I don't think that I need 52v. 48v battery may be overly cautious, but I read it is most efficient and reliable (I am cost conscious and want lowest cost of repair/replacement ) So what can you tell me I'm missing with regard to battery choice ordering the kit from Luna? (why are only 52v batteries offered today?)

    Well ... if your bike frame has a big 'ol turkey jowel on the front of the bottom bracket like this, no BBS motor will likely fit:

    If it's like this, you may have a chance if you're willing to mount the motor straight down or slightly back:


    You need to make the measurements, here's one of the reference documents.

    In very general terms, the narrowest width motor that fits is best - having to do with an optimal chain line and somewhat, knees.

    But, this Surly horse has a 197mm rear hub (correct?), and from what I can discern from other builds with this hub and rear tire width, the 120mm motor is often used.

    Either measure first, find some other sucker who's already done it, or take an edumacated stab at the motor width and cross yer fingers.

    I want to install the BBSHD on a new redesign Surly Ice Cream Truck fat bike frame it has a 100mm BB but I am worried about clearance with the chain stay. Should I go with 120 mm kit to be safe? Any down side to going with 120mm?
