Archer Components' Wireless Electronic D1x Shifter - Review
I hope you were the beta tester that caused some hardware changes (diodes and stuff like that) to prevent burning out boards again.

@BobbyLite: you should try a 50t, it's awesome! (if you prefer to ride at a higher cadence)

Archer Components' Wireless Electronic D1x Shifter - Review
@groghunter: you mean electric shifting? I agree. Pull the shifting axle (the one with the sun gear) out a bit, put a worm gear on it and mount a stepper with a worm perpendicularly. Easy peasy.
Now for some heresy, a pinion would also be ideal for an ebike drive train. Same thing, put a motor in a bigger casing and connect it to the output axle, job done. Half the stuff you need for an ebike (one way clutch, mounting plate on the frame, etc) is already there and is widespread (mounting plate). It could actually be made to be rettofittabla to existing bikes. But Pinion's electric strategy is to have hub motors...

@Archer-Brandon: so you guys are using an ordinary DC motor? You then also need position sensors to ensure correct shifting rates and all? Why not go with a stepper motor? I thought it would be the ideal choice for this application. Could you perhaps elaborate on the design a bit more? I was thinking a simple stepper motor with a ball screw rod to make the motion linear would be the easiest solution for a system like this.
Just out of curiosity, how hard would it be to adapt your system to a Pinion box? And would your system work with a top normal derailleur (about 10 years ago Shimano had reverse shifting systems). The second question is a "for the lulz" style of a question, but I'm genuinely interested about the Pinion.

Enduro Bikes Galore, Including a Prototype GT - EWS Chile 2018
@pakleni: a WHAT?? Which part of it looks like an Evil?
@joehowlett55: point, messed this one up. I accept all the negative votes.
@jollyXroger: um, the Mega has a horizontal shock orientation... More or less same for the Enduro. It is Slash like though
@bman33: or any bike, that is not direct sales, really. Even more so if it's carbon or they try to be a special brand or something. The prices are literally insane.

Nordest Cycles Introduces a Titanium "Enduro" Hardtail With a Pinion Gearbox
@excavator666: sadly can't edit my previous reply, anymore, but, regarding an add on box. I was thinking about one more along the lines of adapting an Eagle trigger to the dual cable nature of a pinion. Though given supposedly high shifting forces the return spring needed in the box and the forces in general might be too much for a standard Sram trigger. The differences in cable pull ratios would be easy to get around i supposes (i'm not sure if the pull length of all gears for the trigger is the same or if they have some variance through the gear range).

Nordest Cycles Introduces a Titanium "Enduro" Hardtail With a Pinion Gearbox
@excavator666: integration wise I meant the gearbox to be mounted directly into a frame instead of to a special mounting plate. There were comments this would streamline the frames even more.
The shifting mechanism would of course make sense to be modular so you could easily exchange the current one and/or decide which you prefer or if you want to upgrade from one to the other while using the same gearbox.

Oh, forgot to mention, i still think Pinion is THE MOST SENSIBLE platform to make an e-bike. All you need to do is mout a motor into an enlarged casing to the front of the gearbox (where you have space frame wise) and figure out where to mount the battery. But no, they are promoting e-hubs as their electric bike solution.
