Thud and Adrian, how well does the 8085 perform compared to the 6474?
Is the ACS Crossfire any quieter than the White freewheels?

Isn't Thud just about the most tempting or the most lusty open-source porn on ES? :lol:adrian_sm said:Now you have me thinking about a BB drive through the gears on my FS bike with this reduction unit. Damn you.
Why not drive the front crank on the left side then? Too complicated or too expensive to do or ?Thud said:the wide BB are actually offset far more on the left, for clearance of the china girl 2-stroke engine kits.
Apples & oranges recommendations for the following typical scenarios please! ...Thud said:As far as compairing the 63mm to an 80mm motor.....apples & oranges. The 80mm motor starts out with a 27% size advantage directly in the leverage ratio that makes outrunners so atractive.

As I understood it, Thud was just stating a fact. If the offset isn't needed for the freewheeling mech, it doesn't matter that it's on the left-hand side. In any case, it's easy enough to rebuild them with the offset on the right-hand side.deVries said:Any thoughts, comments, opinions, or recommendations about this... ...

recumpence said:I am pushing to make the highest quality crank drive that uses the stock derailer and pedal system that I can while keeping an eye on the cost. It looks like the kit consisting of motor, drive unit, FW cranks with chainrings, all mounts, motor and all hardware will come in at around $1,500.
recumpence said:#4 The freewheeling crank. This is one thing I am really excited about! It will use a second support bearing to eliminate the overloaded freewheel bearing issue that is so common with freewheeling cranks. It will also use standard 130mm BCD chainrings for multiple ratio options. I am very excited to have come up with a solution to the FW crank bearing issue. I am not the first to do this, but I think it is the first to be readily available. My system will come with this new FW crank system and a new lengthened bottom bracket.#4 The freewheeling crank.

recumpence said:#1 Motor. This system will be compatible with Astro motors, but for those who are looking for lower power, lower cost, and lighter weight while retaining quality, it will also be compatible with a small outrunner based on a standard Maxx Products outrunner. This motor will retail for under $200. The normal motor is $180. However, my motor will use a longer shaft and a few other minor changes. Also, this motor is readily available and I can pick them up 15 minutes from my house! And if someone manages to smoke the motor, the stator/windings retail for $50 and are easy to replace! This motor uses high-end bearings and is, overall, a very high quality motor! I am thrilled to find this option so close to my house. Also, these motors have been tested in very dirty environments. So, I am confident it will run well in this application. It is also a very quiet motor.

Brentis said:Beautiful work.
I am considering BB mid-drive of 750-1500w, & as light & simple as possible, for a recent acquisition.
Light, simple, RC, BB driven NuVinci N171.
This sure would fit the bill. Especially with the C.A. RC development.
Cannot wait to see a couple examples in action.
Your pricing is very reasonable.
I have started another penny jar.
Best of luck expanding your empire.
Has your beta tester started a build thread, or have you gotten any feedback?Thud said:Beta unit is boxed & in the mail.
this is going into the beta stage now...we'll see what meets the testers expectations & where we can improve the packadge.
